本文研究了1453例神经性厌食症和神经性贪食症患者侵入性和重复性拔毛、拔毛癖的典型特征与强迫性和冲动性特征之间的关系。我们进行了一系列回归模型来检验与强迫症相关的强迫特征的相对影响；与饮食失调有关的强迫特征；与伤害回避、完美主义和追求新奇相关的特质特征；还有自残。最后的模型减少了样本（n=928）检验了脉冲属性的额外贡献。每20个人中就有一个支持拔头发。有证据表明，对强迫行为的认可与强迫症谱系呈正相关。在饮食失调患者中，拔头发可能更符合仪式性强迫，而不是冲动冲动。
We studied the relation between intrusive and repetitive hair-pulling, the defining feature of trichotillomania, and compulsive and impulsive features in 1453 individuals with anorexia nervosa and bulimia nervosa. We conducted a series of regression models examining the relative influence of compulsive features associated with obsessive compulsive disorder; compulsive features associated with eating disorders; trait features related to harm avoidance, perfectionism and novelty seeking; and self harm. A final model with a reduced sample (n=928) examined the additional contribution of impulsive attributes. One out of 20 individuals endorsed hair-pulling. Evidence of a positive association with endorsement of compulsive behavior of the obsessive compulsive spectrum emerged. Hair-pulling may be more consonant with ritualistic compulsions than impulsive urges in those with eating disorders.
