This randomized trial compared a combined Acceptance and Commitment Therapy/Habit Reversal Training (ACT/HRT) to a wait list control in the treatment of adults with trichotillomania (TTM). Twenty five participants (12 treatment and 13 waitlist) completed the trial. Results demonstrated a significant reduction in hair pulling severity, impairment ratings, and hairs pulled, along with significant reductions in experiential avoidance and both anxiety and depressive symptoms in the ACT/HRT group compared to the wait list control. Reductions generally were maintained at a 3-month follow-up. Decreases in experiential avoidance and greater treatment compliance were significantly correlated with reductions in TTM severity, implying that targeting experiential avoidance may be useful in the treatment of TTM. Other implications and suggestions for future research are noted.

A small randomized trial (25 completers) comparing ACT plus habit reversal to a wait list. Wait list subjects then receive ACT/HR. Solid hair pulling, anxiety, and depression outcomes, maintained at a 3 month follow up. Wait list participants also improve once they get ACT. AAQ moves and correlates well with outcomes.
