Trichotillomania (TTM) involves the chronic pulling out of hair to the point of hair loss or thinning, which continues despite repeated attempts to stop. Behavior therapy is a promising treatment for the condition, but studies have been limited by the lack of a credible control condition, small sample sizes, follow-up periods of short duration, and low participation by underrepresented populations. In the current article, the authors describe the theoretical rationale for an acceptance-enhanced form of behavior therapy for TTM in adults and describe the methodology used to test the efficacy of this intervention against a psychoeducation and supportive control condition. In addition, the authors discuss the importance of and difficulties encountered with enrolling minority participants into TTM research, as well as strategies used to enhance minority recruitment. Finally, the authors discuss the instruments, procedures, and related outcomes of the fidelity measures used in the randomized controlled trial.

拔毛癖的接受增强行为疗法：随机对照试验的原理、方法和招募少数族裔参与者的策略。

拔毛癖 (TTM) 是指慢性拔除头发直至脱发或稀疏，尽管多次尝试停止，但这种现象仍在持续。行为疗法是一种很有前景的治疗方法，但由于缺乏可靠的对照条件、样本量小、随访时间短以及代表性不足的人群参与度低，研究受到限制。在本文中，作者描述了针对成人 TTM 的接受增强行为疗法的理论依据，并描述了用于测试这种干预措施针对心理教育和支持性控制条件的有效性的方法。此外，作者还讨论了招募少数族裔参与者参与 TTM 研究的重要性和遇到的困难，以及用于加强少数族裔招募的策略。最后，作者讨论了随机对照试验中使用的保真度测量的仪器、程序和相关结果。
