To explore the usefulness of emotional and environmental cues in distinguishing different patterns and potential subtypes of hair pulling in trichotillomania, we looked at the responses of 75 chronic hair pullers who had identified relevant cues for hair pulling from a 339 item list. Principal components analysis suggested two independent components which were important to hair pulling, one distinguished by negative affective states (NA), and the other by sedentary activities and contemplative attitudes (S). High NA scores were related to hair pulling which was the focus of the Ss' attention, as well as with increased prevalence of lifetime obsessive compulsive disorder, other anxiety disorders, current and past depression, and obsessive compulsive personality disorder. High SA scores were related to a history of major depression only. Weighted scores on these components may be useful in further elaborating the phenomenology of trichotillomania and designing appropriate treatment interventions.
为探究情绪和环境线索在区分拔毛癖中不同拔毛模式及潜在亚型方面的作用，我们观察了75名慢性拔毛者的反应，这些拔毛者从一份339项的清单中识别出了与拔毛相关的线索。主成分分析表明有两个对拔毛很重要的独立成分，一个以消极情绪状态（NA）为特征，另一个以久坐活动和沉思态度（S）为特征。高NA分数与成为研究对象关注焦点的拔毛行为相关，也与终生强迫症、其他焦虑症、当前及既往抑郁症以及强迫型人格障碍的患病率增加有关。高SA分数仅与重度抑郁症病史相关。这些成分的加权分数可能有助于进一步阐述拔毛癖的现象学特征并设计合适的治疗干预措施。
