- BACKGROUND: Research on Internet-based interventions typically use digital versions of pen and paper self-report symptom scales. However, adaptation into the digital format could affect the psychometric properties of established self-report scales. Several studies have investigated differences between digital and pen and paper versions of instruments, but no systematic review of the results has yet been done.OBJECTIVE: This review aims to assess the interformat reliability of self-report symptom scales used in digital or online psychotherapy research.METHODS: Three databases (MEDLINE, Embase, and PsycINFO) were systematically reviewed for studies investigating the reliability between digital and pen and paper versions of psychiatric symptom scales.RESULTS: From a total of 1504 publications, 33 were included in the review, and interformat reliability of 40 different symptom scales was assessed. Significant differences in mean total scores between formats were found in 10 of 62 analyses. These differences were found in just a few studies, which indicates that the results were due to study effects and sample effects rather than unreliable instruments. The interformat reliability ranged from r=.35 to r=.99; however, the majority of instruments showed a strong correlation between format scores. The quality of the included studies varied, and several studies had insufficient power to detect small differences between formats.CONCLUSIONS: When digital versions of self-report symptom scales are compared to pen and paper versions, most scales show high interformat reliability. This supports the reliability of results obtained in psychotherapy research on the Internet and the comparability of the results to traditional psychotherapy research. There are, however, some instruments that consistently show low interformat reliability, suggesting that these conclusions cannot be generalized to all questionnaires. Most studies had at least some methodological issues with insufficient statistical power being the most common issue. Future studies should preferably provide information about the transformation of the instrument into digital format and the procedure for data collection in more detail.

- Background. Cognitive behaviour therapy (CBT) is an effective treatment for obsessive-compulsive disorder (OCD) but access to CBT is limited. Internet-based CBT (ICBT) with therapist support is potentially a more accessible treatment. There are no randomized controlled trials testing ICBT for OCD. The aim of this study was to investigate the efficacy of ICBT for OCD in a randomized controlled trial. less thanbrgreater than less thanbrgreater thanMethod. Participants (n=101) diagnosed with OCD were randomized to either 10 weeks of ICBT or to an attention control condition, consisting of online supportive therapy. The primary outcome measure was the Yale-Brown Obsessive Compulsive Scale (YBOCS) administered by blinded assessors. less thanbrgreater than less thanbrgreater thanResults. Both treatments lead to significant improvements in OCD symptoms, but ICBT resulted in larger improvements than the control condition on the YBOCS, with a significant between-group effect size (Cohens d) of 1.12 (95% CI 0.69-1.53) at post-treatment. The proportion of participants showing clinically significant improvement was 60% (95% CI 46-72) in the ICBT group compared to 6% (95% CI 1-17) in the control condition. The results were sustained at follow-up. less thanbrgreater than less thanbrgreater thanConclusions. ICBT is an efficacious treatment for OCD that could substantially increase access to CBT for OCD patients. Replication studies are warranted.

Guided Internet-Based Cognitive Behaviour Therapy for Chronic Pain
- 2012

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Chronic pain is a one of the most common causes of disability and sick leave. Psychological factors play a central role in the experience of pain and are important in the management of pain. However, for many people with chronic pain CBT is not available. There is a need to develop alternative ways to deliver treatments that reach more individuals with chronic pain. Internet-based treatments have been shown to be effective for several disorders and recent research suggests that internet-based CBT for chronic pain can be effective. The present thesis included four randomized controlled studies with the aim of evaluating whether guided internet-based treatments based on CBT can help individuals with chronic pain regarding psychological variables.Study I investigated the effects of an internet-based CBT intervention with telephone support for chronic back pain. The study showed reductions in some variables assessed. Study II investigated the effects of an internet-based CBT intervention for chronic back pain without telephone support and with a live structured interview before inclusion. It was found that the treatment can reduce some of the distress associated with chronic pain.Study III investigated the effects of a guided internet-delivered CBT as a secondary intervention. Participants were patients who had previously completed multidisciplinary treatment at a pain management unit. Results showed that the internet-based treatment can be a feasible option for persons with residual problems after completed pain rehabilitation. Effects remained at six-month follow-up. Study IV focused on the effect of a guided internet-delivered acceptance and commitment therapy (ACT) for persons with chronic pain. Results suggest that an internet-delivered ACT treatment can help persons with chronic pain. Effects remained at six-month follow-up.In conclusion, guided internet-based CBT can decrease distress associated with chronic pain.

- 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.

- Background Chronic pain can be treated with cognitive behavioural therapy delivered in multidisciplinary settings. However, relapse is likely, and there is a need for cost-effective secondary interventions for persons with residual problems after rehabilitation. The aim of the present study was to investigate the effects of a guided Internet-delivered cognitive behavioural intervention for patients who had completed multidisciplinary treatment at a pain management unit. Methods A total of 72 persons with residual pain problems were included in the study and were randomized to either treatment for 8 weeks or to a control group who were invited to participate in a moderated online discussion forum. The participants had different chronic pain conditions, and a majority were women (72%). Twenty-two percent of the participants dropped out of the study before the post-treatment assessment. Results Intent-to-treat analyses demonstrated differences on the catastrophizing subscale of the Coping Strategies Questionnaire (Cohens d=0.70), in favour of the treatment group but a small within-group effect. Differences were also found on other measures of pain-related distress, anxiety and depressive symptoms. A 6-month follow-up exhibited maintenance of improvements. Conclusions We conclude that Internet-delivered treatment can be partly effective for persons with residual problems after completed pain rehabilitation.
