Acceptance-enhanced behavior therapy (AEBT) for trichotillomania and chronic skin picking: exploring the effects of component sequencing

This pilot study examined the utility of acceptance-enhanced behavior therapy (AEBT) for trichotillomania (TTM) and chronic skin picking (CSP) and the impact of altering treatment sequence on overall treatment efficacy. Participants referred to a TTM and CSP specialty clinic were assessed by an independent evaluator within separate, nonconcurrent, multiple-baseline designs across participants. The first group of three participants received habit-reversal training (HRT) followed by acceptance and commitment therapy (ACT), and the second group of two participants received ACT followed by HRT. Results indicated that AEBT greatly reduced pulling/picking for all five participants and that the order in which ACT and HRT were implemented made little or no difference in short-term treatment outcome. Conclusions, limitations, and future areas of research are discussed.
