Abstract

Background: Trichotillomania is a common psychiatric disorder classified as an obsessive-compulsive and related condition in DSM-5. Despite being first described in the 1800s, little is known about its phenomenology and clinical presentation. Most information about trichotillomania is based on small samples.

Methods: Clinical and demographic data were collected from 858 individuals with trichotillomania who participated in research studies that used in-person assessments with validated instruments.

Results: A total of 858 adolescents and adults (mean age 29.3; range 11 to 65; 89.9% female) were recruited. The peak age of symptom onset was 11 to 15, and most affected individuals (93.5%) had symptom onset before age 20. Individuals reported pulling from several body sites, and the most frequent triggers were stress and the feel of their hair. Comorbidities included major depressive disorder, generalized anxiety disorder, and skin picking disorder. Most individuals with trichotillomania (61.7%) previously had received treatment. Among those who had received treatment, more individuals had received medication (43.4%) than psychotherapy (33.0%).

Conclusions: This study sheds new light on the clinical presentation and phenomenology of trichotillomania. Results highlight the need for further research into its clinical presentation, longitudinal course, and optimal treatment approaches.

拔毛癖的临床特点。

背景：拔毛癖是DSM-5中一种常见的强迫症及其相关疾病。尽管在19世纪首次被描述，但人们对其现象学和临床表现知之甚少。关于拔毛癖的大多数信息都是基于小样本。方法：从858名拔毛癖患者中收集临床和人口统计数据，这些患者参与了使用经验证的仪器进行当面评估的研究。结果：共招募了858名青少年和成年人（平均年龄29.3岁；年龄在11岁至65岁之间；女性占89.9%）。症状发作的高峰年龄为11至15岁，大多数受影响的个体（93.5%）在20岁之前出现症状。据报道，有人从几个身体部位拔出，最常见的诱因是压力和头发的感觉。合并症包括重度抑郁障碍、广泛性焦虑障碍和皮肤挑刺障碍。大多数拔毛癖患者（61.7%）以前接受过治疗。在接受过治疗的人中，接受过药物治疗的人（43.4%）多于接受过心理疗法的人（33.0%）。结论：本研究为拔毛癖的临床表现和现象学提供了新的线索。研究结果强调了对其临床表现、纵向病程和最佳治疗方法进行进一步研究的必要性。
