Journal article (peer-reviewed)abstract
- Dizziness is a common and often untreated symptom in the general population. The aim of this study was to investigate the effects of a combined cognitive-behavioral/vestibular rehabilitation (VR) program, using a randomized control design. A total of 29 participants were randomized to treatment consisting of psychoeducation, vestibular exercises, relaxation and cognitive interventions, or to serve as waiting list controls. Measures of dizziness-related handicap, dizziness-provoking movements, and daily diary registrations of dizziness symptoms at pre- and post-treatment showed statistically significant improvements in many domains, which translated to moderate effect sizes. These findings provide preliminary support for the combination of Cognitive-behavioral therapy (CBT) and VR methods in the treatment of dizziness.

Journal article (peer-reviewed)abstract
- Abstract Nineteen elderly hearing impaired subjects participated in an experimental treatment study and received either behavioural hearing tactics or served as untreated controls. Treatment was supplied in the form of a self-help treatment manual supplied with telephone contacts during 4 consecutive weeks. The treatment manual included applied relaxation, communication strategies training, advice to relatives, information, and coping skills. Assessments (pre-post) were conducted in a structured interview measuring coping behaviour. In order to evoke behavioural compensation small acoustic provocations were included in the interview. Pre-post assessments also included questionnaires, daily registered hearing problems, and hours of daily hearing aid use. Results showed significant beneficial effects in favour of the treatment in terms of self-assessed problems and behaviour change.

Free choice of treatment content, support on demand and supervision in internet-delivered CBT for adults with depression : A randomized factorial design trial
- 2023
-
In: Behaviour Research and Therapy. - : Elsevier. - 0005-7967 .- 1873-622X. ; 162
-
Journal article (peer-reviewed)abstract
- Even if much is known regarding the effects of internet-delivered cognitive behaviour therapy (ICBT) for depression there are several topics that have not been studied. In this factorial design trial with 197 participants we investigated if clients in ICBT could select treatment modules themselves based on a selection of 15 tailored treatment modules developed for use in ICBT for depression. We contrasted this against clinician-tailored module selection. We also investigated if support on demand (initiated by the client) could work as well as scheduled support. Finally, we tested if clients that were mentioned in supervision would improve more than clients not mentioned (with the exception of acute cases). The treatment period lasted for 10 weeks, and we measured effects at post-treatment and two-year follow-up. Measures of depression and secondary outcomes were collected at pre-treatment, post-treatment and two-year follow-up. Overall, within-group effects were large across con-ditions (e.g., d = 1.73 on the BDI-II). We also found a small but significant difference in favour of self-tailored treatment over clinician-tailored (d = 0.26). Within-group effects for the secondary measures were all moderate to large including a test of knowledge about CBT. The other two contrasts "support on demand" and "supervision" yielded mostly non-significant differences, with the exception of a larger dropout rate in the support on demand condition. There were few negative effects (2.2%). Effects were largely maintained at a two-year follow-up. We conclude that clients can choose treatment modules and that support on demand may work. The role of su-pervision is not yet clear as advice can be transferred across clients.

Therapeutic alliance in guided internet-delivered cognitive behavioural treatment of depression, generalized anxiety disorder and social anxiety disorder
- 2012
-
In: Behaviour Research and Therapy. - : Elsevier. - 0005-7967 .- 1873-622X. ; 50:9, s. 544-550
-
Journal article (peer-reviewed)abstract
- Guided internet-delivered cognitive behaviour therapy (ICBT) has been found to be effective in several controlled trials, but the mechanisms of change are largely unknown. Therapeutic alliance is a factor that has been studied in many psychotherapy trials, but the role of therapeutic alliance in ICBT is less well known. The present study investigated early alliance ratings in three separate samples. Participants from one sample of depressed individuals (N = 49), one sample of individuals with generalized anxiety disorder (N = 35), and one sample with social anxiety disorder (N = 90) completed the Working Alliance Inventory (WAI) modified for ICBT early in the treatment (weeks 3-4) when they took part in guided ICBT for their conditions. Results showed that alliance ratings were high in all three samples and that the WAI including the subscales of Task, Goal and Bond had high internal consistencies. Overall, correlations between the WAI and residualized change scores on the primary outcome measures were small and not statistically significant. We conclude that even if alliance ratings are in line with face-to-face studies, therapeutic alliance as measured by the WAI is probably less important in ICBT than in regular face-to-face psychotherapy.

Using the Internet to provide cognitive behaviour therapy
- 2009
-
In: BEHAVIOUR RESEARCH AND THERAPY. - : Elsevier BV. - 0005-7967 .- 1873-622X. ; 47:3, s. 175-180
-
Journal article (peer-reviewed)abstract
- A new treatment form has emerged that merges cognitive behaviour therapy with the Internet. By delivering treatment components, mainly in the form of texts presented via web pages, and provide ongoing support using e-mail promising outcomes can be achieved. The literature on this novel form of treatment has grown rapidly over recent years with several controlled trials in the field of anxiety disorders, mood disorders and behavioural medicine. For some of the conditions for which Internet-delivered CBT has been tested, independent replications have shown large effect sizes, for example in the treatment of social anxiety disorder. In some studies, Internet-delivered treatment can achieve similar outcomes as in face-to-face CBT, but the literature thus far is restricted mainly to efficacy trials. This article provides a brief summary of the evidence, comments on the role of the therapist and for which patient and therapist this is suitable. Areas of future research and exploration are identified.

Both early and late changes in psychological variables relate to treatment outcome for musculoskeletal pain patients at risk for disability
- 2013
-
In: Behaviour Research and Therapy. - : Elsevier. - 0005-7967 .- 1873-622X. ; 50:11, s. 726-734
-
Journal article (peer-reviewed)abstract
- We know little about why some people get better after psychological treatments for pain disability, whereas other people do not. In order to understand differences in treatment response, we need to explore processes of change during treatment. It has been suggested that people with pain complaints who change early in treatment have better outcomes. Therefore, we aimed to investigate whether changes in psychological variables at different time points are related to outcome, and whether early or late changes are better predictors of outcome. We used the fear avoidance model as a theoretical framework. We followed 64 patients weekly over 6–7 weeks and then determined outcome. Our findings indicate that people who decrease in catastrophizing and function early in treatment as well as in depressive symptoms, worry, fear avoidance beliefs and function late in treatment have better outcomes. Early decreases in function, and late decreases in depressive symptoms and worry uniquely predict improvements in disability. While early and late changes covaried concurrently, there were no significant sequential relationships between early and late changes. Changes in the proposed process variables in the fear avoidance model, early as well as late in treatment, thus add valuable information to the explanation of outcome.

Internet-based treatment of social phobia: A randomized controlled trial comparing unguided with two types of guided self-help
- 2011
-
In: BEHAVIOUR RESEARCH AND THERAPY. - : Elsevier Science B.V., Amsterdam.. - 0005-7967 .- 1873-622X. ; 49:3, s. 158-169
-
Journal article (peer-reviewed)abstract
- Internet-based self-help for social phobia with minimal therapist support via email have shown efficacy in several controlled trials by independent research teams. The role and necessity of therapist guidance is, however, still largely unclear. The present study compared the benefits of a 10-week web-based unguided self-help treatment for social phobia with the same intervention complemented with minimal, although weekly, therapist support via email. Further, a third treatment arm was included, in which the level of support was flexibly stepped up, from no support to email or telephone contact, on demand of the participants. Eighty-one individuals meeting diagnostic criteria for social phobia were randomly assigned to one of the three conditions. Primary outcome measures were self-report measures of symptoms of social phobia. Secondary outcome measures included symptoms of depression, interpersonal problems, and general symptomatology. Measures were taken at baseline, post-treatment, and at 6-month follow-up. Data from a telephone-administered diagnostic interview conducted at post-treatment were also included. Results showed significant symptom reductions in all three treatment groups with large effect sizes for primary social phobia measures (Cohens d=1.47) and for secondary outcome measures (d=1.16). No substantial and significant between-groups effects were found on any of the measures (Cohens d=00-.36). Moreover, no difference between the three conditions was found regarding diagnosis-free status, clinically significant change, dropout rates, or adherence measures such as lessons or exercises completed. These findings indicate that Internet-delivered treatment for social phobia is a promising treatment option, whether no support is provided or with two different types of therapist guidance.

Effectiveness and cost-effectiveness of individually tailored Internet-delivered cognitive behavior therapy for anxiety disorders in a primary care population : A randomized controlled trial
- 2014
-
In: Behaviour Research and Therapy. - : Elsevier BV. - 0005-7967 .- 1873-622X. ; 59, s. 1-11
-
Journal article (peer-reviewed)abstract
- A significant proportion of the general population suffers from anxiety disorders, often with comorbid psychiatric conditions. Internet-delivered cognitive behavior therapy (ICBT) has been found to be a potent treatment for patients with specific psychiatric conditions. The aim of this trial was to investigate the effectiveness and cost-effectiveness of ICBT when tailoring the treatment to address comorbidities and preferences for primary-care patients with a principal anxiety disorder. One hundred participants were recruited through their primary-care contact and randomized to either treatment or an active control group. The treatment consisted of 7-10 weekly individually assigned modules guided by online therapists. At post-treatment, 46% of the treatment group had achieved clinically significant improvement on the primary outcome measure (CORE-OM) and between-group effect sizes ranged from d = 0.20 to 0.86, with a mean effect of d = 0.59. At one-year follow-up, within-group effect sizes varied between d = 0.53 to 1.00. Cost analysis showed significant reduction of total costs for the ICBT group, the results were maintained at one-year follow-up and the incremental cost-effectiveness ratio favored ICBT compared to control group. Individually tailored ICBT is an effective and cost-effective treatment for primary-care patients with anxiety disorders with or without comorbidities. Trial Registration: Clinicaltrials.gov: NCT01390168.

Long-term, non-specific spinal pain: reliable and valid subgroups of patients
- 2001
-
In: Behaviour Research and Therapy. - : Elsevier. - 0005-7967 .- 1873-622X. ; 39:1, s. 75-87
-
Journal article (peer-reviewed)abstract
- The aim of this study was to identify reliable and valid subgroups of spinal pain patients, using data from the Swedish version of the Multidimensional Pain Inventory (MPI-S). A second aim was to test the generalisability of the three patient profiles described in earlier studies on the MPI (”adaptive coper”, ”dysfunctional” and ”interpersonally distressed” patients). The study base consisted of two samples of individuals suffering from long-term, non-specific spinal pain and the results were validated across these samples. Cluster analysis was used to detect distinct groups of patients and the validity of these subgroups was evaluated on variables not used to generate the cluster solution. One subgroup was characterised by lower pain severity, lower interference with everyday activities, lower affective distress and higher life control than the other two subgroups. This patient profile was similar to the MPI adaptive coper patients. A second subgroup resembled the dysfunctional patient profile, thus displaying a worse adjustment to chronic pain than the AC patients. The third patient group reported significantly lower levels of social support from “significant others” than the other subgroups. This patient profile was similar to that of the interpersonally distressed patient group. Taken together, the results support the reliability, validity and generalisability of three subgroups of chronic pain patients derived from the MPI-S.

Internet-vs. group-delivered cognitive behavior therapy for insomnia : A randomized controlled non-inferiority trial
- 2015
-
In: Behaviour Research and Therapy. - : Elsevier. - 0005-7967 .- 1873-622X. ; 70, s. 47-55
-
Journal article (peer-reviewed)abstract
- The aim of this study was to compare guided Internet-delivered to group-delivered cognitive behavioral therapy (CBT) for insomnia. We conducted an 8-week randomized controlled non-inferiority trial with 6-months follow-up. Participants were forty-eight adults with insomnia, recruited via media. Interventions were guided Internet-delivered CBT (ICBT) and group-delivered CBT (GCBT) for insomnia. Primary outcome measure was the Insomnia Severity Index (ISI), secondary outcome measures were sleep diary data, depressive symptoms, response- and remission rates. Both treatment groups showed significant improvements and large effect sizes for ISI (Within Cohen's d: ICBT post = 1.8, 6-months follow-up = 2.1; GCBT post = 2.1, 6-months follow-up = 2.2). Confidence interval of the difference between groups posttreatment and at FU6 indicated non-inferiority of ICBT compared to GCBT. At post-treatment, two thirds of patients in both groups were considered responders (ISI-reduction > 7p). Using diagnostic criteria, 63% (ICBT) and 75% (GCBT) were in remission. Sleep diary data showed moderate to large effect sizes. We conclude that both guided Internet-CBT and group-CBT in this study were efficacious with regard to insomnia severity, sleep parameters and depressive symptoms. The results are in line with previous research, and strengthen the evidence for guided Internet-CBT for insomnia. Trial registration: The study protocol was approved by, and registered with, the regional ethics review board in Linkoping, Sweden, registration number 2010/385-31. (C) 2015 The Authors.

How does persistent pain develop? : An analysis of the relationship between psychological variables, pain and function across stages of chronicity
- 2005
-
In: Behaviour Research and Therapy. - Oxford : Pergamon. - 0005-7967 .- 1873-622X. ; 43:11, s. 1495-1507
-
Journal article (peer-reviewed)abstract
- The fear-avoidance model is an attempt to underscore the importance of cognitive and behavioral factors, in a chain of events linking pain to disability. However, it is not clear at what time point the psychological variables within the model begin to be prominent. The aim of this study was to investigate the role of these psychological variables in the development of a chronic musculoskeletal pain problem. Three stages of chronicity, defined by duration of pain, provided a proxy for the developmental process: <1 year (N=48), 1–3 years (N=47) and >3 years (N=89). Subjects completed questionnaires on fear of movement, catastrophizing, depression, pain and function. The results indicate that the relationship between fear of movement and function is moderated by the stage of chronicity. Regression analyses showed that fear of movement did not explain any variance in the group with pain duration <1 year. Fear of movement did explain variance in the groups with pain duration of 1–3 years and >3 years. This suggests that the time point in the development of a musculoskeletal pain problem might be an essential aspect of the importance of the relationship between psychological components and function.

Journal article (peer-reviewed)abstract
- Chronic stress increases the risk of health problems and absenteeism, with negative consequences for individuals, organizations and society. The aim of the present study was to examine the effect of a brief stress management intervention based on the principles of Acceptance and Commitment Therapy (ACT) on stress and general mental health for Swedish social workers (n = 106) in a randomized, controlled trial. Participants were stratified according to stress level at baseline in order to examine whether initial stress level moderated the effect of the intervention. Two thirds of the participants had high stress levels at baseline (Perceived Stress Scale; score of >= 25). The results showed that the intervention significantly decreased levels of stress and burnout, and increased general mental health compared to a waiting list control. No statistically significant effects were, however, found for those with low levels of stress at baseline. Among participants with high stress, a substantial proportion (42%) reached criteria for clinically significant change. We concluded that the intervention successfully decreased stress and symptoms of burnout, and increased general mental health. Evidence is, thus, provided supporting ACT as brief, stress management intervention for social workers.

Guided internet-delivered acceptance and commitment therapy for chronic pain patients: A randomized controlled trial
- 2013
-
In: Behaviour Research and Therapy. - : Elsevier. - 0005-7967 .- 1873-622X. ; 51:6, s. 307-315
-
Journal article (peer-reviewed)abstract
- Acceptance and commitment therapy (ACT) interventions for persons with chronic pain have recently received empirical support. ACT focuses on reducing the disabling influences of pain through targeting ineffective control strategies and teaches people to stay in contact with unpleasant emotions, sensations, and thoughts. The aim of the present study was to investigate the effect of a guided internet-delivered ACT intervention for persons with chronic pain. A total of 76 patients with chronic pain were included in the study and randomized to either treatment for 7 weeks or to a control group that participated in a moderated online discussion forum. Intent-to-treat analyses showed significant increases regarding activity engagement and pain willingness. Measurements were provided with the primary outcome variable Chronic Pain Acceptance Questionnaire which was in favour of the treatment group. Reductions were found on other measures of pain-related distress, anxiety and depressive symptoms. A six month follow-up showed maintenance of improvements. We conclude that an acceptance based internet-delivered treatment can be effective for persons with chronic pain.

A novel approach for constructing personalized networks from longitudinal perceived causal relations
- 2024
-
In: Behaviour Research and Therapy. - 0005-7967 .- 1873-622X. ; 173
-
Journal article (peer-reviewed)abstract
- Personalized networks of psychological symptoms aim to advance therapy by identifying treatment targets for specific patients. Statistical relations in such networks can be estimated from intensive longitudinal data, but their causal interpretation is limited by strong statistical assumptions. An alternative is to create networks from patient perceptions, which comes with other limitations such as retrospective bias. We introduce the Longitudinal Perceived Causal Problem Networks (L-PECAN) approach to address both these concerns. 20 participants screening positive for depression completed 4 weeks day of brief daily assessments of perceived symptom interactions. Quality criteria of this new method are introduced, answering questions such as “Which symptoms should be included in networks?”, “How many datapoints need to be collected to achieve stable networks?”, and “Does the network change over time?”. Accordingly, about 40% of respondents achieved stable networks and only few respondents exhibited network structure that changed during the assessment period. The method was time-efficient (on average 7.4 min per day), and well received. Overall, L-PECAN addresses several of the prevailing issues found in statistical networks and therefore provides a clinically meaningful method for personalization.

How does change unfold? an evaluation of the process of change in four people with chronic low back pain and high pain-related fear managed with Cognitive Functional Therapy : A replicated single-case experimental design study
- 2019
-
In: Behaviour Research and Therapy. - : Elsevier. - 0005-7967 .- 1873-622X. ; 117, s. 28-39
-
Journal article (peer-reviewed)abstract
- PURPOSE: To understand the process of change at an individual level, this study used a single-case experimental design to evaluate how change in potential mediators related to change in disability over time, during an exposure-based behavioural intervention in four people with chronic low back pain and high pain-related fear. A second aim was to evaluate whether the change (sequential or simultaneous) in mediators and disability occurred at the same timepoint for all individuals.RESULTS: For all participants, visual and statistical analyses indicated that changes in disability and proposed mediators were clearly related to the commencement of Cognitive Functional Therapy. This was supported by standard outcome assessments at pre-post timepoints. Cross-lag correlation analysis determined that, for all participants, most of the proposed mediators (pain intensity, pain controllability, and fear) were most strongly associated with disability at lag zero, suggesting that mediators changed concomitantly and not before disability. Importantly, these changes occurred at different rates and patterns for different individuals, highlighting the individual temporal variability of change.CONCLUSION: This study demonstrated the interplay of factors associated with treatment response, highlighting 'how change unfolded' uniquely for each individual. The findings that factors underpinning treatment response and the outcome changed simultaneously, challenge the traditional understanding of therapeutic change.

-
Journal article (peer-reviewed)abstract
- Previous studies on Internet-based treatment with minimal to moderate therapist guidance have shown promising results for a number of specific diagnoses. The aim of this study was to test a new approach to Internet treatment that involves tailoring the treatment according to the patients unique characteristics and comorbidities. A total of 54 participants, regardless of specific anxiety diagnosis, were included after an in-person, semi-structured diagnostic interview and randomized to a 10 week treatment program or to a control group. Treatment consisted of a number of individually-prescribed modules in conjunction with online therapist guidance. Significant results were found for all dependent measures both immediately following treatment and at 1 and 2 year intervals. Mean between-group effect size including measures of anxiety, depression and quality of life was Cohens d = 0.69 at post-treatment, while the mean within-group effect size was d = 1.15 at post-treatment and d = 1.13 and d = 1.04 at 1 and 2 year follow-up respectively. The tentative conclusion drawn from these results is that tailoring the Internet-based therapy can be a feasible approach in the treatment of anxiety in a homogeneous population.

Long-term outcome of Internet-delivered cognitive-behavioural therapy for social phobia : a 30-month follow-up
- 2009
-
In: Behaviour Research and Therapy. - : Elsevier BV. - 0005-7967 .- 1873-622X. ; 47:10, s. 848-850
-
Journal article (peer-reviewed)abstract
- Internet-delivered guided cognitive behaviour therapy for social anxiety disorder has been found to generate promising short-term results, up to one year posttreatment. No study has however documented longer follow-up periods. In this 30-month follow-up we contacted 57 participants from the original study of which 77.2% (44/57) responded to the Internet-administered outcome measures and 66.7% (38/57) completed a telephone interview. Results showed large pretreatment to follow-up within-group effect sizes for the primary outcome measures (Cohen's d 1.10-1.71), and a majority (68.4%; 26/38) reported improvements in the interview. The findings suggest that the long-term effects seen in previous live treatment CBT trials can occur in Internet-delivered treatment as well.

In: Behaviour Research and Therapy. - : Elsevier BV. - 0005-7967 .- 1873-622X. ; 43:10, s. 1321-1333
-
Journal article (peer-reviewed)abstract
- A randomized trial was conducted comparing 10 individual weekly sessions of cognitive behaviour therapy for panic disorder (PD) with or without agoraphobia with a 10-module self-help program on the Internet. After confirming the PD diagnosis with an in-person structured clinical interview (SCID) 49 participants were randomized. Overall, the results suggest that Internet-administered self-help plus minimal therapist contact via e-mail can be equally effective as traditional individual cognitive behaviour therapy. Composite within-group effect sizes were high in both groups, while the between-group effect size was small (Cohen's d=16). One-year follow-up confirmed the results, with a within-group effect size of Cohen's d=0.80 for the Internet group and d=0.93 for the live group. The results from this study generally provide evidence to support the continued use and development of Internet-distributed self-help programs.

First steps in using machine learning on fMRI data to predict intrusive memories of traumatic film footage

Journal article (peer-reviewed)abstract
- After psychological trauma, why do some only some parts of the traumatic event return as intrusive memories while others do not? Intrusive memories are key to cognitive behavioural treatment for post-traumatic stress disorder, and an aetiological understanding is warranted. We present here analyses using multivariate pattern analysis (MVPA) and a machine learning classifier to investigate whether peri-traumatic brain activation was able to predict later intrusive memories (i.e. before they had happened). To provide a methodological basis for understanding the context of the current results, we first show how functional magnetic resonance imaging (fMRI) during an experimental analogue of trauma (a trauma film) via a prospective event-related design was able to capture an individual's later intrusive memories. Results showed widespread increases in brain activation at encoding when viewing a scene in the scanner that would later return as an intrusive memory in the real world. These fMRI results were replicated in a second study. While traditional mass univariate regression analysis highlighted an association between brain processing and symptomatology, this is not the same as prediction. Using MVPA and a machine learning classifier, it was possible to predict later intrusive memories across participants with 68% accuracy, and within a participant with 97% accuracy; i.e. the classifier could identify out of multiple scenes those that would later return as an intrusive memory. We also report here brain networks key in intrusive memory prediction. MVPA opens the possibility of decoding brain activity to reconstruct idiosyncratic cognitive events with relevance to understanding and predicting mental health symptoms. (C) 2014 The Authors.

Journal article (peer-reviewed)abstract
- Generalized anxiety disorder (GAD) is a disabling condition which can be treated with cognitive behaviour therapy (CBT). The present study tested the effects of therapist-guided internet-delivered acceptance-based behaviour therapy on symptoms of GAD and quality of life. An audio CD with acceptance and mindfulness exercises and a separate workbook were also included in the treatment. Participants diagnosed with GAD (N = 103) were randomly allocated to immediate therapist-guided internet-delivered acceptance-based behaviour therapy or to a waiting-list control condition. A six month follow-up was also included. Results using hierarchical linear modelling showed moderate to large effects on symptoms of GAD (Cohen's d = 0.70 to 0.98), moderate effects on depressive symptoms (Cohen's d = 0.51 to 0.56), and no effect on quality of life. Follow-up data showed maintained effects. While there was a 20% dropout rate, sensitivity analyses showed that dropouts did not differ in their degree of change during treatment. To conclude, our study suggests that internet-delivered acceptance-based behaviour therapy can be effective in reducing the symptoms of GAD.

Journal article (peer-reviewed)abstract
- Objective: The current study evaluated the efficacy of an Internet-based parent-training program for children with conduct problems. Dose-response ratio and costs for the program were also considered. Method: Parents of 104 children (aged 3-12 years) were randomly allocated to either parent training or a waitlist control condition. Diagnostic assessment was conducted at baseline and parent ratings of child externalizing behaviors and parent strategies were completed before and after treatment and at 6-month follow-up. Results: At post-treatment assessment, children whose parent(s) had received the intervention showed a greater reduction in conduct problems compared to the waitlist children. Between group intent-to-treat effect sizes (Cohen's d) on the Eyberg Intensity and Problem scales were .42 and .72, respectively (study completers .66 and 1.08). In addition, parents in the intervention group reported less use of harsh and inconsistent discipline after the treatment, as well as more positive praise. Effects on behavior problems were maintained at 6-month follow-up. Conclusions: The results support the efficacy of parent training, administered through Internet, with outcomes comparable to many of the group-based parent training programs. The efficacy, low cost, and higher accessibility make this intervention a fitting part in a stepped-care model.

Pavlovian threat conditioning can generate intrusive memories that persist over time
- 2022

Journal article (peer-reviewed)abstract
- Although Pavlovian threat conditioning has proven to be a useful translational model for the development of anxiety disorders, it remains unknown if this procedure can generate intrusive memories - a symptom of many anxiety-related disorders, and whether intrusions persist over time. Social support has been related to better adjustment after trauma however, experimental evidence regarding its effect on the development of anxietyrelated symptoms is sparse. We had two aims: to test whether threat conditioning generates intrusive memories, and whether different social support interactions impacted expression of emotional memories. Non-clinical participants (n = 81) underwent threat conditioning to neutral stimuli. Participants were then assigned to a supportive, unsupportive, or no social interaction group, and asked to report intrusive memories for seven days. As predicted, threat conditioning can generate intrusions, with greater number of intrusions of CS+ (M = 2.35, SD = 3.09) than CS- (M = 1.39, SD = 2.17). Contrary to predictions, compared to no social interaction, supportive social interaction did not reduce, and unsupportive interaction did not increase skin conductance of learned threat or number of intrusions. Unsupportive interaction resulted in a relative difference in number of intrusions to CS + vs CS-, suggesting that unsupportive interaction might have increased image-based threat memories. Intrusions were still measurable one year after conditioning (one-year follow-up; n = 54), when individuals with higher trait anxiety and greater number of previous trauma experiences reported more intrusions. Our findings show that threat conditioning can create long-lasting intrusions, offering a novel experimental psychopathology model of intrusive memories with implications for both research on learning and clinical applications.

Applicability Of A Cognitive Model Of Worry To Children And Adolescents
- 2012
-
In: Behaviour Research and Therapy. - : Elsevier BV. - 1873-622X .- 0005-7967. ; 50, s. 341-349
-
Journal article (peer-reviewed)abstract
- Background: Intolerance of uncertainly (IU), cognitive avoidance (CA) and positive beliefs about worry (PB) independently predict worry frequency in older adolescents and adults, and when targeted together in treatment produce significant reductions in both worry and anxiety in this age range. The present study addresses a gap in the literature by testing whether a cognitive model of excessive worry and anxiety incorporating these process variables is applicable to children and adolescents. Method: Primary and secondary school students (n=515; aged 7-19 years) completed modified self-report measures of worry frequency, anxiety, IU, CA and PB and a path analysis undertaken to test whether IU was a higher order variable for CA and PB and whether the relationship between IU/CA/PB and anxiety was mediated by worry frequency. Results: Significant (bivariate) correlations were observed between the measures of IU, PB, CA, worry and anxiety across the age range. However separate path models had to be fitted for children (aged 7-12 years) and adolescents (aged 13-19) with PB being dropped from the child model. CA was related to anxiety only through worry in children while IU showed direct paths to worry and anxiety in both children and adolescents. Conclusions: Cognitive models of persistent worry in adults and older adolescents may, with some modification, have applicability to children. Further testing and refinement of these cognitive models of worry may lead to improvements in existing treatments for anxious youth.

Reducing the threat value of chronic pain : A preliminary replicated single-case study of interoceptive exposure versus distraction in six individuals with chronic back pain
- 2009
-
In: Behaviour Research and Therapy. - Amsterdam : Elsevier. - 0005-7967 .- 1873-622X. ; 47:8, s. 721-728

Journal article (peer-reviewed)abstract
- This paper describes a preliminary experimental evaluation of a technique intended to help people suffering from chronic back pain and low pain acceptance to alter the aversiveness or threat value of their persisting pain. Using a multiple baseline cross-over design six individuals with chronic back pain were taught to use a form of interoceptive exposure as well as a relaxation/distraction breathing-based technique in the presence of their pain. Half the participants used one method for three weeks, and then crossed over to the other method for a further three weeks. The other half did the reverse. Assessments were conducted at pre/post treatment and at a three month follow-up. Daily monitoring of pain-related distress was also completed. The results indicated moderately high improvements in pain acceptance across most participants and corresponding declines in pain-related distress. No clear differences occurred between conditions, but the changes on disability and catastrophising scales for most cases were consistent with those reported after more substantial interventions. The study raises some important clinical and methodological issues that could inform future research in this area.

Stepped care versus face-to–face cognitive behavior therapy for panic disorder and social anxiety disorder : Predictors and moderators of outcome
- 2015
-
In: Behaviour Research and Therapy. - : Elsevier. - 0005-7967 .- 1873-622X. ; 71, s. 76-89
-
Journal article (peer-reviewed)abstract
- Objective: To investigate predictors and moderators of treatment outcome by comparing immediate face-to-face cognitive behavioral therapy (FtF-CBT) to a Stepped Care treatment model comprising three steps: Psychoeducation, Internet-delivered CBT, and FtF-CBT for panic disorder (PD) and social anxiety disorder (SAD).Method: Patients (N = 173) were recruited from nine public mental health out-patient clinics and randomized to immediate FtF-CBT or Stepped Care treatment. Characteristics related to social functioning, impairment from the anxiety disorder, and comorbidity was investigated as predictors and moderators by treatment format and diagnosis in multiple regression analyses.Results: Lower social functioning, higher impairment from the anxiety disorder, and a comorbidcluster C personality disorder were associated with significantly less improvement, particularly among patients with PD. Furthermore, having a comorbid anxiety disorder was associated with a better treatment outcome among patients with PD but not patients with SAD. Patients with a comorbid depression had similar outcomes from the different treatments, but patients without comorbid depression had better outcomes from immediate FtF-CBT compared to guided self-help.Conclusions: In general, the same patient characteristics appear to be associated with the treatment outcome for CBT provided in low- and high-intensity formats when treated in public mental health care clinics. The findings suggest that patients with lower social functioning and higher impairment from their anxiety disorder benefit less from these treatments and may require more adapted and extensive treatment.ClinicalTrials.govIdentifier: NCT00619138.

Working alliance and competence as predictors of outcome in cognitive behavioral therapy for social anxiety and panic disorder in adults
- 2016
-
In: Behaviour Research and Therapy. - : Elsevier BV. - 0005-7967 .- 1873-622X. ; 77, s. 40-51
-
Journal article (peer-reviewed)abstract
- Objective: The research on the association between the working alliance and therapist competence/adherence and outcome from cognitive behavioral therapy (CBT) is limited and characterized by inconclusive findings. This study investigates the working alliance and competence/adherence as predictors of outcome of CBT for social anxiety disorder(SAD) and panic disorder (PD).Method: Eighty-two clinically referred patients (58.5% female; age: M = 33.6 years, SD = 10.3) with PD (n = 31) or SAD (n = 51) were treated with 12 sessions of manualized CBT by 22 clinicians with limited CBT experience in a randomized controlled effectiveness trial. Independent assessors rated the CBT competence/adherence of the therapists using a revised version of the Cognitive Therapy Adherence and Competence Scale, and the patients rated the quality of the working alliance using the Working Alliance Inventory-short form in therapy sessions 3 and 8. The outcome was assessed by independent assessors as well as by patients self-report. A total of 20.7% of the patients (27.5% SAD, 9.7% PD) dropped out during treatment. The association between the alliance, competence/adherence, outcome and dropout was investigated using multiple regression analyses.Results: Higher therapist' competence/adherence early in the therapy was associated with a better outcome among PD patients, lower competence/adherence was associated with dropout among SAD patients. Higher rating of the alliance late in the therapy was associated with a better outcome, whereas lower alliance rating late in the therapy was associated with dropout.Conclusion: The findings indicate that the therapist competence/adherence and the working alliance have independent contributions to the outcome from CBT for anxiety disorders, but in different phases of the treatment.

Clinical effectiveness and cost-effectiveness of Internet- vs. group-based cognitive behavior therapy for social anxiety disorder : 4-Year follow-up of a randomized trial
- 2014
-
In: Behaviour Research and Therapy. - : Elsevier. - 0005-7967 .- 1873-622X. ; 59, s. 20-29
-
Journal article (peer-reviewed)abstract
- Social anxiety disorder (SAD) is common, debilitating and associated with high societal costs. The disorder can be effectively treated with Internet-based cognitive behavior therapy (ICBT), but no previous study has investigated the long-term clinical or health economic effects of ICBT for SAD in comparison to an evidence-based control treatment. The aim of the study was to investigate the clinical effectiveness and cost-effectiveness of ICBT compared to cognitive behavioral group therapy (CBGT) four years post-treatment. We conducted a 4-year follow-up study of participants who had received ICBT or CBGT for SAD within the context of a randomized controlled non-inferiority trial. The cost-effectiveness analyses were conducted taking a societal perspective. Participants in both treatment groups made large improvements from baseline to 4-year follow-up on the primary outcome measure (d = 1.34-1.48) and the 95% CI of the mean difference on the primary outcome was well within the non-inferiority margin. ICBT and CBGT were similarly cost-effective and both groups reduced their indirect costs. We conclude that ICBT for SAD yields large sustainable effects and is at least as long-term effective as CBGT. Intervention costs of both treatments are offset by net societal cost reductions in a short time. (C) 2014 Elsevier Ltd. All rights reserved.

Cost-effectiveness of Internet-based cognitive behavior therapy vs. cognitive behavioral group therapy for social anxiety disorder: Results from a randomized controlled trial
- 2011
-
In: Behaviour Research and Therapy. - : Elsevier. - 0005-7967 .- 1873-622X. ; 49:11, s. 729-736

Journal article (peer-reviewed)abstract
- Social anxiety disorder (SAD) is highly prevalent and associated with a substantial societal economic burden, primarily due to high costs of productivity loss. Cognitive behavior group therapy (CBGT) is an effective treatment for SAD and the most established in clinical practice. Internet-based cognitive behavior therapy (ICBT) has demonstrated efficacy in several trials in recent years. No study has however investigated the cost-effectiveness of ICBT compared to CBGT from a societal perspective, i.e. an analysis where both direct and indirect costs are included. The aim of the present study was to investigate the cost-effectiveness of ICBT compared to CBGT from a societal perspective using a prospective design. We conducted a randomized controlled trial where participants with SAD were randomized to ICBT (n = 64) or CBGT (n = 62). Economic data were assessed at pre-treatment, immediately following treatment and six months after treatment. Results showed that the gross total costs were significantly reduced at six-month follow-up, compared to pre-treatment in both treatment conditions. As both treatments were equivalent in reducing social anxiety and gross total costs, ICBT was more cost-effective due to lower intervention costs. We conclude that ICBT can be more cost-effective than CBGT in the treatment of SAD and that both treatments reduce societal costs for SAD.

Mediators in psychological treatment of social anxiety disorder: Individual cognitive therapy compared to cognitive behavioral group therapy
- 2013
-
In: Behaviour Research and Therapy. - : Elsevier. - 0005-7967 .- 1873-622X. ; 51:10, s. 696-705
-
Journal article (peer-reviewed)abstract
- According to cognitive-behavioral models of social anxiety disorder (SAD), four of the important maintaining mechanisms are avoidance, self-focused attention, anticipatory processing and post-event cognitive processing. Individual cognitive therapy (ICT) and cognitive behavioral group therapy (CBGT) both have substantial empirical support. However, it is unclear whether they achieve their effects by similar or different mechanisms. The aim of this study was to investigate whether changes in the four maintenance processes mediate clinical improvement in la and CBGT for SAD. We analyzed data from participants (N = 94) who received either ICT or CBGT in two separate RCTs. The results showed that ICT had larger effects than CBGT on social anxiety and each of the four potential mediators. More pertinently, moderated mediation analyses revealed significant between-treatment differences. Whereas improvement in ICT was mainly mediated by reductions in avoidance and self-focused attention, improvement in CBGT was mediated by changes in self-focused attention and in anticipatory and post-event processing. These results support the importance of the putative mediators, but suggest that their relative weights are moderated by treatment type.

Predictors in Internet-delivered cognitive behavior therapy and behavioral stress management for severe health anxiety
- 2015
-
In: Behaviour Research and Therapy. - : Elsevier BV. - 0005-7967 .- 1873-622X. ; 64, s. 49-55
-
Journal article (peer-reviewed)abstract
- Severe health anxiety can be effectively treated with exposure-based Internet-delivered cognitive behavior therapy (ICBT), but information about which factors that predict outcome is scarce. Using data from a recently conducted RCT comparing ICBT (n = 79) with Internet-delivered behavioral stress management (IBSM) (n = 79) the presented study investigated predictors of treatment outcome. Analyses were conducted using a two-step linear regression approach and the dependent variable was operationalized both as end state health anxiety at post-treatment and as baseline-to post-treatment improvement. A hypothesis driven approach was used where predictors expected to influence outcome were based on a previous predictor study by our research group. As hypothesized, the results showed that baseline health anxiety and treatment adherence predicted both end state health anxiety and improvement. In addition, anxiety sensitivity, treatment credibility, and working alliance were significant predictors of health anxiety improvement. Demographic variables, i.e. age, gender, marital status, computer skills, educational level, and having children, had no significant predictive value. We conclude that it is possible to predict a substantial proportion of the outcome variance in ICBT and IBSM for severe health anxiety. The findings of the present study can be of high clinical value as they provide information about factors of importance for outcome in the treatment of severe health anxiety.

Predictors of outcome in Internet-based cognitive behavior therapy for severe health anxiety
- 2013

Journal article (peer-reviewed)abstract
- Internet-based cognitive behavior therapy (CBT) for severe health anxiety can be effective, but not all patients achieve full remission. Under these circumstances, knowledge about predictors is essential for the clinician in order to make reliable treatment recommendations. The primary aim of this study was to investigate clinical, demographic, and therapy process-related predictors of Internet-based CBT for severe health anxiety. We performed three types of analyses on data from a sample comprising participants (N = 81) who had received Internet-based CBT in a randomized controlled trial. Outcomes were a) end state health anxiety, b) improvement in health anxiety (continuous change scores), and c) clinically significant improvement. Outcomes were assessed at six-month follow-up. The results showed that the most stable predictors of both end state health anxiety and improvement were baseline health anxiety and depressive symptoms. Treatment adherence, i.e. the number of completed treatment modules, also significantly predicted outcome. Notably, health anxiety at baseline was positively associated with symptom improvement while depressive symptoms was negatively related to improvement. Demographic factors were largely without significant impact on end state symptoms or improvement. We conclude that baseline symptom burden and adherence to treatment have strong predictive effects in Internet-based CBT for severe health anxiety.

Sudden gains in internet-based cognitive behaviour therapy for severe health anxiety
- 2014
-
In: Behaviour Research and Therapy. - : Elsevier. - 0005-7967 .- 1873-622X. ; 54, s. 22-29
-
Journal article (peer-reviewed)abstract
- OBJECTIVE: A sudden gain is defined as a large and stable individual improvement occurring between two consecutive treatment sessions. Sudden gains have been shown to predict better long-term improvement in several treatment studies, including cognitive behavioural therapy for depression and anxiety disorders, but have not been studied in the treatment of health anxiety or any form of internet-based cognitive behavioural therapy. The aim of this study was to investigate the role of sudden gains in internet-based cognitive behavioural therapy for severe health anxiety.METHOD: We examined the occurrence and significance of sudden gains in measures of health anxiety in 81 participants receiving internet-based cognitive behavioural therapy. We compared patients with sudden gains, patients without sudden gains, and patients with gradual gains.RESULTS: Thirteen participants (16%) experienced one sudden gain in health anxiety with individual sudden gains distributed across the treatment. As expected, patients with a sudden gain showed larger improvements than patients without a sudden gain at post-treatment (d = 1.04) and at one-year follow-up (d = 0.91) on measures of health anxiety.CONCLUSIONS: Consistent with previous studies, sudden gains in internet-based cognitive behavioural therapy are associated with significantly larger and stable treatment effects up to one-year follow-up.

Approach as a key for success : Reduced avoidance behaviour mediates the effect of exposure therapy for fibromyalgia
- 2019
-
In: Behaviour Research and Therapy. - : Elsevier. - 0005-7967 .- 1873-622X. ; 122
-
Journal article (peer-reviewed)abstract
- Fibromyalgia (FM) is a prevalent chronic pain disorder associated with large suffering and substantial societal costs. Pain-related avoidance behaviour and hypervigilance to bodily symptoms are common in FM and contribute in maintaining and exacerbating the disorder. Exposure therapy targeting avoidance behaviours and hypervigilance has shown promise in the treatment of FM. The present study investigated mediators of treatment outcome in exposure therapy for FM. We used data from a randomised trial, where 140 participants were allocated to 10-week Internet-delivered exposure therapy or to a waiting-list control condition. The main outcome variable (FM symptoms) and the hypothesized mediators (FM-related avoidance behaviour, mindful non-reactivity and FM-related worry) were measured weekly throughout treatment. Mediation analyses were conducted using linear mixed effects models with bootstrap replication and time-lagged analysis. Results indicated that all three process variables were significant mediators of FM severity. However, in the time-lagged analyses, only FM-related avoidance behaviour displayed a unidirectional relationship over time with FM symptoms, suggesting a causal effect. Thus, results illustrate that changes in avoidance behaviour mediate the outcome of exposure on FM symptoms, which implies that avoidance behaviour is an important treatment target in exposure therapy.

Shared and distinct effect mediators in exposure-based and traditional cognitive behavior therapy for fibromyalgia : Secondary analysis of a randomized controlled trial
- 2024
-
In: Behaviour Research and Therapy. - : Elsevier. - 0005-7967 .- 1873-622X. ; 178
-
Journal article (peer-reviewed)abstract
- Fibromyalgia is a chronic pain condition associated with substantial suffering and societal costs. Traditional cognitive behavior therapy (T-CBT) is the most evaluated psychological treatment, but exposure therapy (Exp-CBT) has shown promise with a pronounced focus on the reduction of pain-related avoidance behaviors. In a recent randomized controlled trial (N = 274), we found that Exp-CBT was not superior to T-CBT (d = −0.10) in reducing overall fibromyalgia severity. This study investigated pain-related avoidance behaviors, pain catastrophizing, hypervigilance, pacing, overdoing and physical activity as potential mediators of the treatment effect. Mediation analyses were based on parallel process growth models fitted on 11 weekly measurement points, and week-by-week time-lagged effects were tested using random intercepts cross-lagged panel models. Results indicated that a reduction in avoidance behaviors, pain catastrophizing, and hypervigilance were significant mediators of change in both treatments. An increase in pacing and a reduction in overdoing were significant mediators in T-CBT only. Physical activity was not a mediator. In the time-lagged analyses, an unequivocal effect on subsequent fibromyalgia severity was seen of avoidance and catastrophizing in Exp-CBT, and of overdoing in T-CBT. Exposure-based and traditional CBT for fibromyalgia appear to share common treatment mediators, namely pain-related avoidance behavior, catastrophizing and hypervigilance.

Intrusive memories : A mechanistic signature for emotional memory persistence
- 2020
-
In: Behaviour Research and Therapy. - : Elsevier BV. - 0005-7967 .- 1873-622X. ; 135
-
Journal article (peer-reviewed)abstract
- Memories of negative emotional events persist more over time relative to memories for neutral information. Such persistence has been attributed to heightened encoding and consolidation processes. However, reactivation of the encoded information may also lead to reduced memory decay through rehearsal or a reconsolidation processes. Here, we tested whether involuntary intrusive memories, spontaneously arising following a stressful event and reactivating its memory, function to prevent memory decay, enhancing its persistence. Participants watched a stressful film containing scenes of aversive material. Memory for the film contents was tested immediately post film using a visual recognition test. In the following five days, participants recorded intrusive memories of the film using a digitized diary. After 5-days, memory for the film contents was retested. Results indicate that in the immediate aftermath of film watching, participant's memory scores were similarly high for scenes that were later experienced as intrusions and scenes that did not intrude, suggesting effective encoding for all scenes. However, persistence of memory for scenes that intruded was preserved relative to memory for scenes that did not intrude, pointing to a mechanism through which negative intrusive memories persist over time. Implications for memory modification interventions in trauma-related psychopathology are discussed.

Behavioral avoidance moderates the effect of exposure therapy for irritable bowel syndrome: A secondary analysis of results from a randomized component trial
- 2021

In: Behaviour Research and Therapy. - : Elsevier BV. - 0005-7967 .- 1873-622X. ; 141
-
Journal article (peer-reviewed)abstract
- Past research has failed to identify consistent moderators of outcomes in psychological treatments for irritable bowel syndrome (IBS). The aim of this study was to test previously identified mediators as potential moderators of the effects of exposure therapy on IBS symptoms in a previously published randomized component trial. In total, 309 participants with IBS were randomized to internet-delivered cognitive behavioral treatment that included exposure (ICBT) or to the same treatment protocol without exposure (ICBT-WE) and were asked to report on gastrointestinal symptoms at pretreatment, posttreatment and weekly during the treatment. Pretreatment scores of The Visceral Sensitivity Index (VSI) and The Irritable Bowel Syndrome Behavioral Responses Questionnaire (IBS-BRQ) (i.e., gastrointestinal anxiety and avoidance behavior) were evaluated as predictors and moderators. Piecewise latent growth curve models were employed to evaluate moderators during distinct phases of the trial, prior to and following the onset of exposure in ICBT. Results revealed that pretreatment scores on IBS-BRQ (avoidance) moderated the effect of exposure therapy during the specific phase in which exposure was implemented in ICBT, with higher avoidance scores linked to stronger positive effects of exposure. VSI did not serve as predictor nor moderator. Adding exposure to CBT seems to be especially important for persons with moderate to high levels of avoidance behaviors in order to reduce gastrointestinal symptoms.

Clients' in-session acceptance and cognitive defusion behaviors in acceptance-based treatment of tinnitus distress
- 2009
-
In: Behaviour Research and Therapy. - : Elsevier. - 0005-7967 .- 1873-622X. ; 47:6, s. 523-528
-
Journal article (peer-reviewed)abstract
- Cognitive-behavioral treatment (CBT) is considered to be an effective treatment of distress associated with tinnitus (perception of internal noises without any Outer auditory stimulation), but the processes by which the therapy works remain Unclear. Mindfulness and acceptance is receiving increased attention in the treatment literature for chronic medical conditions. However, few Studies have examined these and related processes with behavioral or observer measures. In the present Study 57 videotapes (a total of 1710 min) from 19 clients who participated in a Controlled trial of an acceptance-based treatment for tinnitus distress, were coded for frequency and peak level of verbal behaviors expressing either acceptance or cognitive defusion. Frequency of cognitive defusion behaviors and peak level of cognitive defusion as well as peak level of acceptance rated in Session 2, predicted symptom reduction 6 month following treatment. These relationships were not accounted for by the improvement that had occurred prior to the measurement point of the process variables. Moreover, prior symptom changes could not predict process variables rated later in therapy (after most of the improvement in therapy had occurred). Thus, clients' in-session acceptance and cognitive defusion behaviors appear to play an important role in the reduction of negative impact of tinnitus.

Two-year outcome of internet-based relapse prevention for partially remitted depression
- 2013
-
In: Behaviour Research and Therapy. - : Elsevier BV. - 0005-7967 .- 1873-622X. ; 51:11, s. 719-722
-
Journal article (peer-reviewed)abstract
- The objective of the study was to investigate the long-term effects of internet-based relapse prevention for sufferers of partially remitted depression. Eighty-four individuals with partially remitted unipolar depression were randomized to either internet-based CBT (iCBT) or to a control group. After the ten week intervention period the participants were followed for 24 months and diagnostic interviews conducted to detect relapse. The intervention and monthly self-ratings of depressive symptoms were administered via an internet-based platform that ensured secure communication with all participants. Significantly fewer participants in the iCBT group had experienced a relapse compared with those in the control group two years after the internet-based intervention. The relapse rate in the iCBT group was 13.7% (CI 95% = 2.5–24.9) and in the control group it was 60.9% (CI 95% = 44.8–77). Furthermore, a significantly larger proportion of the iCBT group experienced remission two years after the intervention compared with the control group. Internet-based CBT seems promising for preventing relapse in sufferers of partially remitted depression.
