Shyness 1: Distance treatment of social phobia over the Internet

Objective: The purpose of the present study was to examine the effectiveness of an Internet-based clinician-assisted computerized cognitive behavioural therapy programme for social phobia. Method: A total of 105 individuals with social phobia were randomly assigned to a six-lesson cognitive behavioural treatment programme or to a waitlist control group. Treatment consisted of four components: six online lessons; homework assignments; participation in an online discussion forum; and regular email contact with a therapist. An intention-to-treat model was used for data analyses. Results: A total of 78% of treatment group participants completed all lessons, and post-treatment data were obtained from 93/105 participants. Significant post-treatment differences between treatment and waitlist participants were found on two measures of symptoms of social phobia. Mean within- and between-group effect sizes (Cohen's d) for the primary social phobia outcome measures were 1.15, and 0.95, respectively. Conclusions: These results were comparable with those obtained in exemplary face-to-face treatment programmes. They provide further positive data about the utility of Internet-based guided self-help programmes for people with common mental disorders

Randomized controlled trial of Internet cognitive behavioural treatment for social phobia with and without motivational enhancement strategies

Objective: The present study (Shyness 7) has two aims: Firstly, to replicate an earlier trial showing that a self-guided Internet treatment for social phobia is efficacious, and secondly, to examine whether the addition of self-guided motivational enhancement strategies improves completion rates and clinical outcomes. Method: Randomized controlled trial (RCT) of self-guided Internet-based cognitive behavioural treatment (iCBT), or iCBT plus self-guided motivational enhancement strategies (iCBT+MS), was conducted. An intention-to-treat and last observation carried forward model was used for data analyses. The participants consisted of 108 volunteers with social phobia. The iCBT intervention consisted of two online lessons about symptoms and treatment of anxiety disorders and six lessons about management of social phobia (the Shyness programme) with complex automated reminders. The motivational intervention was based on traditional techniques including understanding and exploring ambivalence about change using a cost-benefit analysis, developing and resolving discrepancy between values and symptoms, and enhancing self-efficacy for change. The main outcome measures were the Social Interaction Anxiety Scale and Social Phobia Scale. Results: More iCBT+MS group participants completed the eight lessons than iCBT group participants (75% versus 56%, respectively), but there were no between-group differences in outcome measures at post-treatment or at 3 month follow up. Large mean within-groups effect sizes (Cohen's d) for the two social phobia measures were found for both the iCBT and iCBT+ MS groups (1.1 and 0.95, respectively), which were sustained at 3 month follow up (1.06 and 1.07, respectively). Both iCBT and iCBT+MS group participants reported that the procedures were highly acceptable. Conclusions: Both self-guided versions of the Shyness programme were reliably efficacious, confirming that people with social phobia may significantly benefit from a highly structured self-guided intervention. The addition of motivational techniques increased completion rates but did not improve clinical outcomes or acceptability.8 page(s

Internet treatment for generalized anxiety disorder: a randomized controlled trial comparing clinician vs. technician assistance.

BACKGROUND: Internet-based cognitive behavioural therapy (iCBT) for generalized anxiety disorder (GAD) has been shown to be effective when guided by a clinician. The present study sought to replicate this finding, and determine whether support from a technician is as effective as guidance from a clinician. METHOD: Randomized controlled non-inferiority trial comparing three groups: Clinician-assisted vs. technician-assisted vs. delayed treatment. Community-based volunteers applied to the VirtualClinic (www.virtualclinic.org.au) research program and 150 participants with GAD were randomized. Participants in the clinician- and technician-assisted groups received access to an iCBT program for GAD comprising six online lessons, weekly homework assignments, and weekly supportive contact over a treatment period of 10 weeks. Participants in the clinician-assisted group also received access to a moderated online discussion forum. The main outcome measures were the Penn State Worry Questionnaire (PSWQ) and the Generalized Anxiety Disorder-7 Item (GAD-7). Completion rates were high, and both treatment groups reduced scores on the PSWQ (p<0.001) and GAD-7 (p<0.001) compared to the delayed treatment group, but did not differ from each other. Within group effect sizes on the PSWQ were 1.16 and 1.07 for the clinician- and technician-assisted groups, respectively, and on the GAD-7 were 1.55 and 1.73, respectively. At 3 month follow-up participants in both treatment groups had sustained the gains made at post-treatment. Participants in the clinician-assisted group had made further gains on the PSWQ. Approximately 81 minutes of clinician time and 75 minutes of technician time were required per participant during the 10 week treatment program. CONCLUSIONS: Both clinician- and technician-assisted treatment resulted in large effect sizes and clinically significant improvements comparable to those associated with face-to-face treatment, while a delayed treatment/control group did not improve. These results provide support for large scale trials to determine the clinical effectiveness and acceptability of technician-assisted iCBT programs for GAD. This form of treatment has potential to increase the capacity of existing mental health services. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry ACTRN12609000563268
