Effectiveness of internet-based guided self-help for binge-eating disorder and characteristics of completers versus noncompleters.

OBJECTIVE: Binge-eating disorder (BED) is characterized by recurrent episodes of binge eating, accompanied by a lack of control and feelings of shame. Online intervention is a promising, accessible treatment approach for BED. In the current study, we compared completers with noncompleters in a 10-session guided internet-based treatment program (iBED) based on cognitive behavioral therapy. METHODS: Adults (N = 75) with mild to moderate BED participated in iBED with weekly written support from psychologists. Participants were compared on the Eating Disorder Examination Questionnaire (EDE-Q), diagnostic criteria for BED (BED-Q), major depression inventory (MDI), quality of life (EQ-5D-5L), body mass index (BMI) and sociodemographic variables. RESULTS: Minor differences were observed between completers and noncompleters on depression. No differences were found in BED-symptoms, BMI, and sociodemographic variables. Participants who completed treatment showed large reductions in eating disorder pathology. DISCUSSION: More research is needed to determine risk factors for attrition or treatment outcome in internet-based interventions for BED. It is suggested that iBED is an efficient intervention for BED. However, more studies of internet-interventions are needed.

STUDY PROTOCOL: EXPOSURE IN VIRTUAL REALITY FOR SOCIAL ANXIETY DISORDER - a randomized controlled superiority trial comparing cognitive behavioral therapy with virtual reality based exposure to cognitive behavioral therapy with in vivo exposure.

BACKGROUND: Social Anxiety Disorder (SAD) is characterized by an intense fear of negative judgement by others. Cognitive Behavioral Therapy (CBT) is recommended for treatment, but a substantial part of individuals with SAD either do not seek treatment or drop-out. CBT with Virtual Reality (VR)-based exposure has several advantages compared to traditional exposure methods, mainly due to increased control of situational elements. The aim of the current study is to develop a CBT program containing VR-based exposure. The intervention is targeted to adult patients suffering from SAD and treatment effect will be assessed by changes in SAD symptoms. METHODS: This article describes the study protocol of a Randomized Controlled Trial with three arms: 1) CBT with VR exposure based on 360° videos 2) CBT with in vivo exposure and 3) VR relaxation therapy. There will be 30 participants in each arm with a crossover at the end of the treatment period during which the participants in the third group will be randomly re-allocated to one of the two former groups. The treatment program consists of 10 weekly individual sessions with a psychologist, and a six month follow-up consisting of a questionnaire. The primary outcome measure is reduction in SAD symptoms which will be assessed with the Social Interaction Anxiety Scale (SIAS). DISCUSSION: There are currently no published studies on CBT with VR exposure based on 360° videos for SAD treatment. Furthermore, the current study will be the first Danish SAD treatment program that includes VR technology. TRIAL REGISTRATION: clinicaltrials.gov (NCT03973541) June 3rd 2019.
