Hair pulling disorder (HPD; trichotillomania) and skin picking disorder (SPD; excoriation disorder) are understudied psychiatric disorders. The aim of this study was to examine the prevalence and correlates of HPD and SPD in an acute psychiatric sample. Semistructured interviews and self-report measures were administered to patients in a psychiatric partial hospital (N = 599). The past-month prevalence of HPD and SPD was 2.3% and 9%, respectively. HPD and SPD had highly similar clinical characteristics and a strong co-occurrence. Patients with HPD/SPD were significantly younger than other patients and more likely to be female. Logistic regression controlling for age and sex showed that diagnosis of HPD/SPD was not significantly associated with suicidal ideation, suicidal behaviors, nonsuicidal self-injury, or emotional disorder diagnoses (e.g., borderline personality disorder, major depressive disorder). HPD/SPD status was significantly associated with an increased risk of generalized anxiety disorder. However, patients with HPD/SPD did not differ from other patients on self-report measures of generalized anxiety, depression, and distress intolerance. HPD and SPD are common and frequently co-occurring disorders in psychiatric settings.
拔毛障碍（HPD；拔毛癖）和皮肤搔抓障碍（SPD；皮肤搔抓症）是研究较少的精神障碍。本研究的目的是调查急性精神科样本中HPD和SPD的患病率及其相关因素。对一家精神科日间医院的患者（N = 599）进行了半结构化访谈和自我报告测量。过去一个月中HPD和SPD的患病率分别为2.3%和9%。HPD和SPD具有高度相似的临床特征且共病率很高。患有HPD/SPD的患者明显比其他患者年轻，且更可能为女性。在控制年龄和性别的逻辑回归分析中，HPD/SPD的诊断与自杀意念、自杀行为、非自杀性自伤或情绪障碍诊断（如边缘型人格障碍、重度抑郁症）无显著关联。HPD/SPD状态与广泛性焦虑障碍风险增加显著相关。然而，在广泛性焦虑、抑郁和痛苦不耐受的自我报告测量方面，患有HPD/SPD的患者与其他患者并无差异。HPD和SPD在精神科环境中是常见且经常共病的疾病。
