- This controlled study, evaluated an Internet-delivered self-help program plus minimal therapist contact via e-mail for people suffering front panic disorder. Out of the 500 individuals screened using the self-administered diagnostic instrument Composite International Diagnostic Interview in shortened form (World Health Organization, 1999), 41 fulfilled the inclusion criteria. These participants were randomized to either treatment via the Internet or to a waiting-list control. The main components of the treatment were psychoeducation. breathing retraining, cognitive restructuring, interoceptive exposure. in vivo exposure, and relapse prevention. From pre- to post- test self-help, participants improved significantly more on almost all dimensions. The results from this experiment generally provide evidence for the continued use and development of self-help programs for panic disorder distributed via the Internet.

- Approximately 14% of the working-age Swedish population are either on long-term sick leave or early retirement due to disability. Substantial increase of sick listing,reports of work disabilities and early retirement due to stress and musculoskeletal chronic pain suggest a need for methods of preventing loss of function resulting from these conditions. The present preliminary investigation examined the effects of a brief Acceptance and Commitment Therapy (ACT) intervention for the treatment of public health sector workers who showed chronic stress/pain and were at risk for high sick leave utilization. ACT was compared in an additive treatment design with medical treatment as usual (MTAU). A group of 19 participants were randomly distributed into 2 groups. Both conditions received MTAU. The ACT condition receivedfour 1-hour weekly sessions of ACT in addition to MTAU. At post and 6-month followup, ACT participants showed fewer sick days and used fewer medical treatment resources than those in the MTAU condition. No significant differences were found inlevels of pain, stress, or quality of life. Improvements in sick leave and medical utilization could not be accounted for by remission of stress and pain in the ACT group as no between-group differences were found for stress or pain symptoms.

- Worry is a common phenotype in both psychiatric patients and the normal population. Worry can be seen as a covert behavior with primary function to avoid aversive emotional experiences. Our research group has developed a treatment protocol based on an operant model of worry, where we use exposure -based strategies to extinguish the catastrophic worry thoughts. The aim of this study was to test this treatment delivered via the Internet in a large-scale randomized controlled trial. We randomized 140 high-worriers [PSWQ]) to either Internet-based extinction therapy (IbET) or to a waiting-list condition (WL). Results showed that IbET was superior to WL with an overall large between-group effect size of d 1.39 (95% confidence interval [1.04,1.73]) on the PSWQ. In the IbET group, 58% were classified as responders. The corresponding figure for WL participants was 7%. IbET was also superior to the WL on secondary outcome measures of anxiety, depression, meta-cognitions, cognitive avoidance, and quality of life. Overall treatment results were maintained for the IbET group at 4- and 12-month follow-up. The results from this trial are encouraging as they indicate that worry can be targeted with an accessible and novel intervention for worry. Replication trials with active control group are needed.

Tidskriftsartikel (refereegranskat)abstract
- Despite its high prevalence, individuals suffering from skin-picking disorder (SPD) face limited access to treatment due to several factors, including geographical and economic barriers, as well as a shortage of properly trained therapists. Offering Internet-delivered therapy could be a solution to these barriers. This study aimed to evaluate the efficacy of therapist-guided Internet-delivered acceptance-enhanced behavior therapy (iBT) for SPD compared to a wait-list control condition. Participants randomized to the intervention group received 10 weeks of iBT (n = 35), while those in the control group were placed on a wait-list (n = 35). The primary outcome was the Skin Picking Scale—Revised (SPS-R). Mixed-model regression analyses demonstrated a significantly greater improvement in SPD symptoms in the iBT group compared to the control group at posttreatment (between-group difference −5.1 points, F = 9.69, p <.001). The between-group effect size was in the large range, with a bootstrapped d of 1.3 (95% CI [0.92, 1.69]). At posttreatment, 43% of the participants in the iBT group were classified as responders, and 31% were in remission, compared to 0% responders and 3% in remission in the control group. At the 6-month follow-up, the SPD symptoms had increased compared to posttreatment. However, the improvement from pretreatment remained significant. Participants reported a high level of satisfaction and credibility of the treatment, and a perceived good level of working alliance. Compared to wait-list control, iBT is an efficacious treatment for SPD at posttreatment and follow-up, with the potential to substantially increase the availability and access to evidence-based treatment for this disorder. Replication studies, particularly those comparing iBT to an active control, are warranted.

Internet-Based Mindfulness Treatment for Anxiety Disorders : A Randomized Controlled Trial

- Mindfulness-based interventions have proven effective for the trans diagnostic treatment of heterogeneous anxiety disorders. So far, no study has investigated the potential of mindfulness-based treatments when delivered remotely via the Internet. The current trial aims at evaluating the efficacy of a stand-alone, unguided, Internet-based mindfulness treatment program for anxiety. Ninety-one participants diagnosed with social anxiety disorder, generalized anxiety disorder, panic disorder, or anxiety disorder not otherwise specified were randomly assigned to a mindfulness treatment group (MTG) or to an online discussion forum control group (CG). Mindfulness treatment consisted of 96 audio files with instructions for various mindfulness meditation exercises. Primary and secondary outcome measures were assessed at pre-, post-treatment, and at 6-months follow-up. Participants of the MTG showed a larger decrease of symptoms of anxiety, depression, and insomnia from pre- to postassessment than participants of the CG (Cohen's d(between) = 0.36-0.99). Within effect sizes were large in the MTG (d = 0.82-1.58) and small to moderate in the CG (d = 0.45-0.76). In contrast to participants of the CG, participants of the MTG also achieved a moderate improvement in their quality of life. The study provided encouraging results for an Internet-based mindfulness protocol in the treatment of primary anxiety disorders. Future replications of these results will show whether Web-based mindfulness meditation can constitute a valid alternative to existing, evidence-based cognitive-behavioural Internet treatments.

Forskningsöversikt (refereegranskat)abstract
- Personalized medicine is aimed at identifying which characteristics of an individual predict the outcome of a specific treatment, in order to get a better match between the individual and the treatment received. We conducted a systematic review and meta-analysis of randomized trials comparing two psychotherapies directly in a group of depressed patients with a specific characteristic. We focused on the six most examined types of psychotherapy for adult depression. Our searches resulted in 41 studies with 2,741 patients who met inclusion criteria. These 41 studies examined 27 specific characteristics of patients. Power calculations indicated that we would need 4 studies for each characteristic to find a clinically relevant effect size set at g = 0.50 and 16 studies for an effect size of 0.24. Only 3 patient characteristics were found to have sufficient power and to significantly moderate treatment outcomes. Cognitive-behavioral therapy was found to be more effective than other therapies in older adults (g= 0.29), in patients with comorbid addictive disorders (g = 0.31), and in university students (g = 0.46). Risk of bias was considerable in most of the included studies. It was estimated that it will take another 326 years to have sufficient statistical power for showing an effect size of g = 0.50 of the 27 characteristics, and 1,372 years to show an effect size of 0.24. Although several dozens of studies have compared the effects of psychotherapies in specific target groups, we will need to develop more powerful alternatives to comparative outcome studies in order to identify personalized treatments for depression.
