Abstract：
Measuring trichotillomania is essential for understanding and treating it effectively. Using the Situated Assessment Method (SAM2), we developed a psychometric instrument to assess hair pulling in situations where it occurs. In two studies, pullers evaluated their pulling in relevant situations, along with how much they experience factors that potentially influence it (e.g., external triggers, reduction in negative emotion, negative self-thoughts). Individual measures of pulling, averaged across situations, exhibited high test reliability, construct validity, and content validity. Large differences between situations in pulling were observed, along with large individual-situation interactions (with limited evidence distinguishing focused versus automatic pulling subtypes). In linear regressions for individual participants, factors that influence pulling tended to correlate with pulling as predicted, explaining a median 74%-83% of its variance. By identifying factors that predict pulling for each individual across situations, the SAM2 Trichotillomania Assessment Instrument (TAI) offers a rich understanding of an individual\'s pulling experience, potentially supporting individualized pulling interventions.

测量毛滴虫病对于有效理解和治疗毛滴虫病至关重要。使用现场评估方法(SAM2)，我们开发了一种心理测量工具来评估头发拉扯的情况。在两项研究中，车夫在相关情况下评估了他们的拉力，以及他们经历了多少潜在影响它的因素(例如，外部触发器,减少负面情绪，消极的自我想法)。单独的拉动措施，在不同情况下的平均值，表现出很高的测试可靠性，构造效度，和内容的有效性。观察到拉扯情况之间的巨大差异，以及大量的个体情境互动(有限的证据区分聚焦和自动拉动亚型)。在单个参与者的线性回归中，影响拉动的因素往往与预测的拉动相关，解释了其方差的中位数74%-83%。通过确定预测每个人在不同情况下拉动的因素，SAM2Trichotillomania评估仪器（TAI）提供了对个人拉拔经验的丰富理解，可能支持个性化拉动干预。
