‘Free from BFRB’: Efficacy of Self-Help Interventions for Body-Focused Repetitive Behaviors Conveyed via Manual or Video

We examined the efficacy of three self-help techniques for BFRBs: habit reversal training (HRT), decoupling (DC), and decoupling in sensu (DC-is) and also tested whether a video demonstration is more efficacious to written instructions. A total of 224 participants with at least one BFRB were randomly assigned to two intervention groups (video, manual) receiving access to all techniques or a wait-list control group (1:1:1). A 6-week follow-up assessment was conducted. The Generic Body-Focused Repetitive Behavior Scale (GBS-9) served as primary outcome. The intention-to-treat analysis showed significant improvements for the manual group compared to the wait-list control group on GBS total score and severity and impairment scores. For the per-protocol analyses (i.e., participants had at least read/watched the manual/video), 26.9% of completers in the manual group improved at least 35% in GBS compared to 23.3% (video group) and 15.9% (control). A dose –response relationship emerged for the video group. Subjective ratings by the video and manual groups did not differ; treatment satisfaction was greater for HRT and DC than for DC-is. Results suggest that the manual group showed somewhat stronger effects than the video group when usage frequency w as low. With more frequent usage, improvements in the video condition increased. Future studies should investigate potential order effects of the techniques as well as add-on effects when techniques are used along with other treatment ap...
