拔毛癖 (TTM) 的评估和治疗在过去十年中取得了长足的进步。然而，TTM 的标准化评估和经验支持治疗仍处于发展的早期阶段。我们提出，通过研究拔发的严重程度，可以获得对评估和治疗持续发展重要的信息。拉头发现象学是在一个大型社区样本中对其表现范围进行评估的。尽管 TTM 的估计患病率为 0.6% 与过去的研究一致，但临床上显着的拔毛的估计患病率为 1.2%，表明当前的诊断标准过于严格。总体而言，拔头发的发生率为 6.5%，发病年龄为 15.92 岁。抑郁、焦虑和嘲笑的症状与拔头发呈正相关，而自尊则与拔头发呈负相关。与拔头发最常见的认知是“感觉粗糙”（53.3%）、“感觉不对”（30.0%）、“卷曲”（26.7%）。和“看起来不对劲”（23.3%）。最常与拔头发相关的环境包括“读书时”（38.9%）、“看电视时”（37.0%）和“上课时”（35.25）。建议将研究结果应用于评估和干预制定，并讨论局限性和未来方向。 (C) 2009 Elsevier Ltd. 保留所有权利。
Assessment and treatment of trichotillomania (TTM) has evolved substantially over the past decade. However, standardized assessment and empirically supported treatment for TTM is still in early stages of development. We proposed that information important to the ongoing evolution of assessment and treatment could be obtained through the study of hairpulling across its range of severity. Hairpulling phenomenology was assessed in a large community sample across its range of presentation. Although the estimated prevalence rate of .6% for TTM is congruent with past studies, the 1.2% prevalence estimated for clinically significant hairpulling suggests that the current diagnostic criteria are overlyrestrictive. Overall, hairpulling occurred at a rate of 6.5%, while age of onset was 15.92 years. Symptoms of depression, anxiety, and history of teasing were positively associated with hairpulling, while self-esteem was negatively related to hairpulling. Cognitions most commonly associated with hairpulling were "feels coarse" (53.3%), "doesn't feel right" (30.0%), "is curly" (26.7%). and "doesn't look right" (23.3%). Environments most commonly associated with hairpulling included "while reading" (38.9%), "while watching television" (37.0%), and "in class" (35.25). Applications of findings to assessment and intervention formulation are suggested, and limitations and future directions are discussed. (C) 2009 Elsevier Ltd. All rights reserved.
