The current study examined the characteristics of pathological skin picking (PSP) in a population-based sample. Participants were recruited through several online resources for PSP and related conditions to complete a web-based survey assessing the functional and topographical phenomenology, physical and psychosocial impact, treatment utilization, and associated psychopathology of PSP. A total of 1663 participants consented, of whom 760 were over 18 and met study criteria for PSP. Results showed considerable heterogeneity in picking methods, body sites, and function (e.g., regulation of emotional, sensory, and cognitive states). Participants generally reported moderate psychosocial and physical impact from picking and tended to perceive available treatment as poor in quality. Severity of associated symptoms of psychopathology (depression, anxiety, and stress) was comparable to severity levels found in previous samples of persons with trichotillomania and obsessive-compulsive disorder. Severity of PSP was a statistically significant predictor of overall impairment after controlling for depression and anxiety symptoms. Results suggest that PSP is a significant public health concern in need of further rigorous investigation.
本研究在基于人群的样本中考察了病理性皮肤搔抓（PSP）的特征。通过几个 PSP 及相关病症的在线资源招募参与者，让他们完成一项基于网络的调查，评估 PSP 的功能和拓扑现象学、身体和心理社会影响、治疗利用以及相关精神病理学。共有 1663 名参与者同意参与，其中 760 名年龄在 18 岁以上，符合 PSP 的研究标准。结果显示，搔抓方法、身体部位和功能存在相当大的异质性（例如，调节情绪、感官和认知状态）。参与者普遍报告搔抓对他们造成了中度的心理社会和身体影响，并且倾向于认为现有的治疗质量较差。与以前患有拔毛癖和强迫症的人群样本相比，相关精神病理学症状（抑郁、焦虑和压力）的严重程度相当。在控制抑郁和焦虑症状后，PSP 的严重程度是总体功能障碍的一个统计学显著预测因素。研究结果表明，PSP 是一个需要进一步严格研究的重大公共卫生问题。
