Twohig, M. P., Hayes, S. C., & Masuda, A. (2006). A preliminary investigation of acceptance and commitment therapy as a treatment for chronic skin picking. Behaviour Research and Therapy, 44, 1513-1522.
The effectiveness of a deliberately limited version of Acceptance and Commitment Therapy (ACT) for chronic skin picking was evaluated in a pair of multiple baseline across participants designs. Self-monitoring of skin picking showed that four of the five participants reached near zero levels of picking by post-treatment, but these gains were not fully maintained for three of the four participants at follow-up. The findings of the self-reported skin picking were generally corroborated by ratings of photographs of the damaged areas and by ratings on a validated measure of skin picking severity. All participants rated the intervention as socially acceptable, and reductions were found on measures of anxiety, depression, and experiential avoidance for most participants as a result of the intervention. Results support the construction of more comprehensive ACT protocols for skin picking.
