Abstract

Trichotillomania (TTM) research lacks an ecologically valid phenomenological description despite increasing research efforts. Previous studies primarily rely on retrospective cross-sectional data, emphasizing the need for longitudinal high-frequency assessments to capture the variability of hair pulling.

The objective of this study was to describe hair pulling patterns and episode characteristics by means of ecological momentary assessment (EMA), and to compare those parameters between focused and automatic episodes.

Study procedures included an online screening, a diagnostic interview via telephone, a comprehensive self-report questionnaire and a 10-day EMA-protocol (7 EMAs/day).

Data from 61 individuals who met diagnostic criteria for TTM (age: M = 29.3, SD = 7.47; 92% female) were analyzed (3948 EMAs; 1217 episodes). Participants reported a mean number of 2.00 (SD = 2.31; range: 0–4.9) episodes per day. One third did not report any days without episodes. Hair pulling showed a relatively even distribution throughout the day. Most prominent triggers were tension and visual/tactile cues. The latter were more relevant in focused episodes, whereas “habit/routine” scored higher in automatic episodes.

The results suggest that hair pulling occurs not sporadic but is rather present in daily life. Using real-time data from a clinical sample, the study enhances our comprehension of the phenomenology of TTM which may ultimately advance TTM research.

拔毛症患者的拔毛模式：生态学瞬间评估研究

尽管研究力度不断加大，但对嗜毛症（TTM）的研究却缺乏生态学上有效的现象描述。本研究的目的是通过生态瞬间评估（EMA）来描述拔毛模式和发作特征，并比较集中发作和自动发作的参数。研究程序包括在线筛查、电话诊断访谈、综合自我报告问卷和为期 10 天的 EMA 方案（每天 7 次 EMA）。研究分析了 61 名符合 TTM 诊断标准的患者（年龄：M = 29.3，SD = 7.47；92% 为女性）的数据（3948 次 EMA；1217 次发作）。参与者报告的平均发作次数为每天 2.00 次（SD = 2.31；范围：0-4.9）。有三分之一的人没有报告过任何一天没有发作。拔毛现象在一天中的分布相对均匀。最主要的诱因是紧张和视觉/触觉暗示。结果表明，拔毛现象并非偶发，而是存在于日常生活中。这项研究利用临床样本的实时数据，加深了我们对 TTM 现象的理解，最终可能会推动 TTM 研究。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
