拔毛癖（TTM）是一种以反复拔毛导致明显脱发为特征的疾病，目前尚无“金标准”治疗结果衡量标准。本研究的目的是评估不同评估方法的TTM测量的心理测量特性：自我报告、临床评定的总结量表和临床评定的整体严重程度量表。从28例TTM患者中收集的数据显示，当前量表的心理测量特征混合。自我报告的内部一致性很强，而临床评定的总结量表则没有。一个临床医生评定的总结量表，脱发的总评分和主观评分显示出良好的相互一致性。虽然在测量类型中收敛效度很好，但自我报告与临床评定的整体严重程度量表没有相关性，可能是因为自我报告测量中缺乏脱发严重程度评估。建议采用多方法评估，包括本文中所述的每种测量方法中的一种，以及自我监测和脱发严重程度的测量方法，作为TTM评估的综合最佳实践方法。
Currently there is no "gold standard" treatment outcome measure for trichotillomania (TTM), a disorder characterized by repetitive hair pulling resulting in noticeable hair loss. The goal of the current study was to evaluate the psychometric properties of TTM measures of differing assessment methods: self-report, clinician-rated summary scales, and clinician-rated global severity scales. Data collected from 28 patients with TTM indicated mixed psychometric properties for current scales. Internal consistency was strong for self-report but not clinician-rated summary scales. One clinician-rated summary scale total and subjective ratings of hair loss demonstrated good interrater agreement. Although convergent validity was good within measurement type, self-report did not correlate with clinician-rated global severity scales, perhaps because of absence of hair loss severity assessment on the self-report measure. A multimethod assessment including one of each type of measure reviewed in this paper, along with self-monitoring and measures of hair loss severity, is recommended for a comprehensive best practice approach to TTM assessment.
