ABSTRACT
BACKGROUND AND OBJECTIVES: Cognitive Behavioral Therapy (CBT) is effective for treating eating disorders but it may be difficult to reach patients living far from urban centers. Mobile video-based psychotherapy may potentially improve service reach but has not yet been evaluated. The purpose of this study was to investigate the effects of mobile video-based CBT for eating disorder and to explore the feasibility to use this technology in clinical care. METHODS: A controlled single case multiple baseline design was used which allowed for statistical analyses with randomization tests and non-overlap of all pairs (NAP). Five patients in the first stage of eating disorder treatment were included and the main outcome variable was daily meal frequency. Secondary outcome variables included eating disorder symptoms, psychological distress and treatment satisfaction. RESULTS: The treatment resulted in a significant (pâ¯<â¯.01) increase in daily meal frequency with medium to large effect sizes (combined NAPâ¯=â¯.89). Four participants reported reliable improvements in eating disorder symptoms and three reported improvements in mood. The participants reported high satisfaction with the treatment and with the mobile video-application despite some technical problems. LIMITATIONS: Self-reported data on eating behavior is prone to be biased and the results of single case studies may have limited generalizability. CONCLUSION: CBT can be delivered effectively via a mobile video application and, despite some technological issues, can be well received by patients. All participants in this study had previous low access to mental health services and reported high satisfaction with the treatment format.
