- Traumatic stress has traditionally been studied in the aftermath of traumatic events. In contrast, this study aimed to explore if traumatic stress can occur before an event that is perceived as threatening or feared. Traumatic stress, as related to the forthcoming delivery, was studied in 1224 women. Background data and psychological characteristics were assessed in early pregnancy and traumatic stress and fear of childbirth in late pregnancy. Of all subjects, 2.3% met all DSM-IV criteria for posttraumatic stress disorder (PTSD) and 5.8% fulfilled criteria B, C, and D in late pregnancy. Traumatic stress and fear of childbirth correlated significantly. High trait anxiety, depressive symptomatology, psychological/psychiatric counseling related to childbirth, and self-reported psychological problems, measured in early pregnancy, were risk factors for traumatic stress and fear of childbirth in late pregnancy. Results suggest the occurrence of “pre”traumatic stress (i.e., a threatening forthcoming event provoking symptoms similar to those after a traumatic event).

- The prevalence of having a posttraumatic stress disorder (PTSD) profile after childbirth and women's cognitive appraisal of the childbirth were studied cross sectionally in an unselected sample of all women who had given birth over a 1-year period in Linköping, Sweden. The PTSD profile was assessed by means of Traumatic Event Scale (TES), which is based on diagnostic criteria from Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV; American Psychiatric Association, 1994). The women's cognitive appraisal of the childbirth was measured by means of the Wijma Delivery Expectancy/Experience Questionnaire (W-DEQ). Twenty-eight women (1.7%) of 1640 met criteria for a PTSD profile related to the recent delivery. A PTSD profile was related to a history of having received psychiatric/psychological counseling, a negative cognitive appraisal of the past delivery, mulliparity, and rating the contact with delivery staff in negative terms.

- The present study aimed to examine the prevalence of posttraumatic stress disorder (PTSD) in survivors with low levels of risk factors for PTSD. The sample included 142 adults (58% women, 54% university education, 93% employed/students/retired) on vacation in Southeast Asia during the 2004 Indian Ocean disaster. Semi-structured clinical interviews (SCID-I) were performed after 6 years including PTSD, depression, specific phobia, and alcohol abuse. The 6-year prevalence of PTSD was 11.3% and the current prevalence was 4.2%, with onset mainly within 1 month and remission within 3 years post-disaster. Suicidal ideation and comorbidity were common in PTSD cases. Lifetime prevalence of depression was 19%, specific phobia 7%, and alcohol abuse 4%. The findings suggest elevated levels of PTSD but not other disorders as compared with general population samples, but still lower levels than other disaster samples. Despite benign circumstances, however, the course and burden of PTSD were comparable to similar studies.

- This study evaluated the properties of Swedish versions of self-report measures of posttraumatic stress disorder (PTSD), with emphasis on the Impact of Event Scale–Revised (IES-R). Survey data from adult survivors 1, 3, and 6 years after the 2004 Indian Ocean tsunami (n = 1506) included the IES-R (from which the IES-6 was derived) and the 12-item General Health Questionnaire (GHQ-12). The PTSD Checklist (PCL) was included in one survey. A structured clinical interview was performed after 6 years (n = 142). Factor analyses of the IES-R and PCL indicated that a dysphoric-arousal model provided good fit invariant across assessments. Both measures were accurate in excluding PTSD while all measures provided poorer positive predictive values. The IES-R, but not the IES-6 and GHQ-12, evidenced stability across assessments. In conclusion, the Swedish IES-R and PCL are sound measures of chronic PTSD, and the findings illustrate important temporal aspects of PTSD assessment.

- Cognitive behaviour therapy (CDT) is efficacious for severe health anxiety, but little is known about mechanisms. We analysed putative mediators of change based on 13 weekly assessments in a randomised controlled trial (N = 132) of exposure-based minimal-contact CBT (guided Internet-delivered CBT, unguided Internet-delivered CBT and bibliotherapy) vs. a waitlist control for severe health anxiety. We hypothesised that the effect of CBT on health anxiety would be mediated by non-reactivity to inner experiences, health anxiety behaviours and perceived competence. We also explored somatosensory amplification. In parallel process growth models, nonreactivity, health anxiety behaviours and perceived competence - but not somatosensory amplification - were influenced by CBT and associated with health anxiety. Random intercepts cross-lagged panel models were used to study within-individual ordering of change. None of the putative mediators systematically predicted subsequent changes in health anxiety. Rather, changes in health anxiety predicted subsequent changes in all putative mediators. In summary, CBT influenced health anxiety behaviours, non-reactivity to inner experiences and perceived competence, and these variables were associated with the outcome. However, their role as mediators was not corroborated because we found no evidence that changes in these variables predicted subsequent changes in health anxiety. We encourage further research into mediators of CBT for health anxiety.

- BackgroundThe characteristics of long-term trajectories of distress after disasters are unclear, since few studies include a comparison group. This study examines trajectories of recovery among survivors in comparison to individuals with indirect exposure.MethodsPostal surveys were sent to Swedish tourists, repatriated from the 2004 Indian Ocean tsunami (n = 2268), at 1, 3, and 6 years after the tsunami to assess posttraumatic stress (PTS) and poor mental health. Items were used to ascertain high and moderate disaster exposure groups and an indirect exposure comparison group.ResultsLong-term PTS trajectories were best characterized by a resilient (72.3%), a severe chronic (4.6%), a moderate chronic (11.2%) and a recovering (11.9%) trajectory. Trajectories reported higher levels of PTS than the comparison group. Exposure severity and bereavement were highly influential risk factors.ConclusionsThese findings have implications regarding anticipation of long-term psychological adjustment after natural disasters and need for interventions after a single traumatic event with few secondary stressors.

Virtual reality exposure therapy for anxiety and related disorders : A meta-analysis of randomized controlled trials
- 2019
-
Ingår i: Journal of Anxiety Disorders. - : Elsevier BV. - 0887-6185 .- 1873-7897. ; 61, s. 27-36

Tidskriftsartikel (refereegranskat)abstract
- Trials of virtual reality exposure therapy (VRET) for anxiety-related disorders have proliferated in number and diversity since our previous meta-analysis that examined 13 total trials, most of which were for specific phobias (Powers & Emmelkamp, 2008). Since then, new trials have compared VRET to more diverse anxiety and related disorders including social anxiety disorder (SAD), posttraumatic stress disorder (PTSD), and panic disorder (PD) with and without agoraphobia. With the availability of this data, it is imperative to re-examine the efficacy of VRET for anxiety. A literature search for randomized controlled trials of VRET versus control or in vivo exposure yielded 30 studies with 1057 participants. Fourteen studies tested VRET for specific phobias, 8 for SAD or performance anxiety, 5 for PTSD, and 3 for PD. A random effects analysis estimated a large effect size for VRET versus waitlist (g = 0.90) and a medium to large effect size for VRET versus psychological placebo conditions (g = 0.78). A comparison of VRET and in vivo conditions did not show significantly different effect sizes (g = −0.07). These findings were relatively consistent across disorders. A meta-regression analysis revealed that larger sample sizes were associated with lower effect sizes in VRET versus control comparisons (β = −0.007, p < 0.05). These results indicate that VRET is an effective and equal medium for exposure therapy.

Psychometric properties of the Social Phobia and Anxiety Inventory-Child version in a Swedish clinical sample
- 2013

Ingår i: Journal of Anxiety Disorders. - : Elsevier BV. - 0887-6185 .- 1873-7897. ; 27:5, s. 503-511

Tidskriftsartikel (refereegranskat)abstract
- The Social Phobia and Anxiety Inventory for Children (SPAI-C) is a 26 item, empirically derived self-report instrument developed for assessing social phobic fears in children. Evidence for satisfactory psychometric properties of the SPAI-C has been found in multiple community studies. Since its development, however, no study has presented an extensive psychometric evaluation of SPAI-C in a sample of carefully diagnosed children with social phobia. The present study sought to replicate and expand previous studies by administrating the SPAI-C to a sample of 59 children that fulfilled DSM-IV criteria for social phobia, and 49 children with no social phobia diagnosis. An exploratory factor analysis resulted in a three factor solution reflecting: (1) fear of social interactions, (2) fear of public performance situations, and (3) physical and cognitive symptoms connected with social phobia. These factors appear to parallel domains of social phobia also evident in adults. The SPAI-C total scale and each factor was found to possess good internal consistency, good test–retest reliability and was generally strongly correlated with both self-report and clinician measures of anxiety and fears. The discriminative properties of the total scale were satisfactory.

Incompleteness, harm avoidance, and disgust: A comparison of youth with OCD, anxiety disorders, and no psychiatric disorder
- 2020

Tidskriftsartikel (refereegranskat)abstract
- Psychological models of pediatric obsessive-compulsive disorder (OCD) place a heavy emphasis on harm avoidance as a maintaining factor and target for treatment. Incompleteness and disgust may also play a role in pediatric OCD but remain under studied. Youth with OCD (n=100), anxiety disorders (n=96), and no psychiatric disorder (n=25) completed self-report measures of trait-level incompleteness, harm avoidance, and disgust and current symptoms of OCD, anxiety, and depression. Group differences and associations between emotions, symptoms, and pre- to post-treatment change in overall OCD severity were examined. Youth with OCD and anxiety disorders scored higher on harm avoidance and disgust than youth with no psychiatric disorder. Youth with OCD scored higher on incompleteness than youth with anxiety disorders and youth with no psychiatric disorder. Harm avoidance showed unique associations to self-reported symptoms of OCD, anxiety, and depression while incompleteness was uniquely related to OCD and disgust to anxiety. Within the OCD sample, incompleteness and harm avoidance were differentially related to the major OCD symptom dimensions, and change in incompleteness was uniquely related to pre- to post-treatment change in OCD severity. Trait-level incompleteness appears to play a central role in pediatric OCD and studies investigating its direct involvement in symptoms and associations with treatment outcome are needed. The role of disgust in relation to pediatric OCD remains unclear.
