Abstract
Background: Trichotillomania and skin picking disorder have been characterized as body-focused repetitive behavior (BFRB) disorders (i.e., repetitive self-grooming behaviors that involve biting, pulling, picking, or scraping one's own hair, skin, lips, cheeks, or nails). Trichotillomania and skin picking disorder have also historically been classified, by some, as types of compulsive self-injury as they involve repetitive hair pulling and skin picking, respectively. The question of the relationship of these disorders to more conventional forms of self-injury such as cutting or self-burning remains incompletely investigated. The objective of this study was to examine the relationship of these two disorders with non-suicidal self-injury (NSSI).
Methods: Adults with trichotillomania (n = 93) and skin picking (n = 105) or both (n = 82) were recruited from the general population using advertisements and online support groups and completed an online survey. Participants completed self-report instruments to characterize clinical profiles and associated characteristics. In addition, each participant completed a mental health history questionnaire.
Results: Of the 280 adults with BFRB disorders, 141 (50.1%) reported a history of self-injury independent of hair pulling and skin picking. Participants with a history of self-injury reported significantly worse pulling and picking symptoms (p < .001) and were significantly more likely to have co-occurring alcohol problems (p < .001), borderline personality disorder (p < .001), buying disorder (p < .001), gambling disorder (p < .001), compulsive sex behavior (p < 001), and binge eating disorder (p = .041).
Conclusions: NSSI appears common in trichotillomania and skin picking disorder and may be part of a larger constellation of behaviors associated with impulse control or reward-related dysfunction.
背景：嗜毛症和抠皮症被定性为以身体为中心的重复行为（BFRB）障碍（即涉及咬、拉、抠或刮自己的头发、皮肤、嘴唇、脸颊或指甲的重复性自我修饰行为）。嗜毛症和抠皮症历来也被一些人归类为强迫性自伤，因为它们分别涉及重复性拔毛和抠皮。关于这些障碍与割伤或自焚等更传统形式的自我伤害之间的关系，目前仍未进行全面调查。本研究旨在探讨这两种障碍与非自杀性自伤（NSSI）的关系：方法：通过广告和在线支持小组从普通人群中招募患有毛发搔痒症（93 人）和皮肤搔痒症（105 人）或同时患有这两种疾病的成年人（82 人），并完成在线调查。参与者填写了自我报告工具，以描述临床特征和相关特征。此外，每位参与者还填写了一份心理健康史问卷：结果：在 280 名患有 BFRB 疾病的成年人中，有 141 人（50.1%）报告有自我伤害史，且不包括拔头发和抠皮肤。有自伤史的参与者的拔毛和抠皮症状明显加重（P P P P P P = .041）：结论：非自伤行为在毛发躁狂症和抠皮症中很常见，可能是与冲动控制或奖赏相关功能障碍有关的一系列行为的一部分。
期刊介绍：
CNS Spectrums covers all aspects of the clinical neurosciences, neurotherapeutics, and neuropsychopharmacology, particularly those pertinent to the clinician and clinical investigator. The journal features focused, in-depth reviews, perspectives, and original research articles. New therapeutics of all types in psychiatry, mental health, and neurology are emphasized, especially first in man studies, proof of concept studies, and translational basic neuroscience studies. Subject coverage spans the full spectrum of neuropsychiatry, focusing on those crossing traditional boundaries between neurology and psychiatry.
