Cognitive-behavioral models suggest that certain cognitions and beliefs are functionally related to hair pulling in persons with trichotillomania (TTM), but little empirical data have been collected to test such claims. This study assessed dysfunctional beliefs about appearance, shameful cognitions, and fear of negative evaluation and their relation to hair-pulling severity in a sample of individuals self-reporting a diagnosis of TTM. Results showed significant correlations between these cognitions and hair-pulling severity; however, relations diminished or disappeared when controlling for experiential avoidance, a tendency to avoid or escape from unwanted private events. These findings suggest that treatments targeting cognitions may benefit from focusing on experiential avoidance more broadly.
认知行为模型表明，某些认知和信念在功能上与拔毛癖（TTM）患者的拔毛行为相关，但几乎没有收集到实证数据来检验这些说法。本研究在一个自我报告诊断为TTM的个体样本中，评估了对外表的功能失调信念、羞耻认知、对负面评价的恐惧及其与拔毛严重程度的关系。结果显示，这些认知与拔毛严重程度之间存在显著相关性；然而，在控制经验性回避（一种避免或逃避 unwanted 私人事件的倾向）后，这种关系减弱或消失了。这些发现表明，针对认知的治疗可能会更广泛地关注经验性回避而受益。
