Body-focused repetitive behaviors such as skin picking have gained recent attention in the psychiatric literature. Prevalence of skin picking has not been well researched and is difficult to estimate; however, consequences of such behaviors can include severe medical complications and impaired social and occupational functioning. Given this, this study examined: (1) the prevalence and severity of skin picking in a nonclinical community sample, and (2) associations between skin picking and other measures of psychological functioning. Three hundred and fifty-four participants completed measures of psychological functioning and skin picking frequency and severity. A total of 62.7% endorsed some form of skin picking and 5.4% reported clinical levels of skin picking and associated distress/impact. Direct associations were found between skin picking and depressive, anxiety, and obsessive-compulsive symptoms, which may support the emotional regulation model of pathological skin picking. To establish proper diagnostic classification of pathological skin picking and optimize treatment planning and outcome, further investigation of functional relationships between skin picking and affective distress is needed.
诸如抠皮肤之类的专注于身体的重复行为最近在精神病学文献中受到了关注。抠皮肤的患病率尚未得到充分研究且难以估计;然而,此类行为的后果可能包括严重的医学并发症以及社交和职业功能受损。鉴于此,本研究考察了:(1)非临床社区样本中抠皮肤的患病率和严重程度,以及(2)抠皮肤与其他心理功能指标之间的关联。354名参与者完成了心理功能以及抠皮肤频率和严重程度的测量。共有62.7%的人认可某种形式的抠皮肤行为,5.4%的人报告抠皮肤及相关困扰/影响达到临床水平。研究发现抠皮肤与抑郁、焦虑和强迫症状之间存在直接关联,这可能支持病理性抠皮肤的情绪调节模型。为了对病理性抠皮肤建立恰当的诊断分类并优化治疗计划和结果,需要进一步研究抠皮肤与情感困扰之间的功能关系。
