ABSTRACT

We developed the MGH Hairpulling Scale to provide a brief, self-report instrument for assessing repetitive hairpulling. Seven individual items, rated for severity from 0 to 4, assess urges to pull, actual pulling, perceived control, and associated distress. We administered the scale to 119 consecutive patients with chronic hairpulling. Statistical analyses indicate that the seven items form a homogenous scale for the measurement of severity in this disorder.

    ABSTRACT: Despite its prevalence and a growing body of research, significant gaps remain in the knowledge of trichotillomania (TTM). The current study sought to address this issue by examining personality characteristics, impulsivity, and experiential avoidance of those with TTM compared to an age and gender matched sample. 56 Female participants (28 with TTM and 28 non-clinical age-matched controls) completed the Personality Assessment Inventory (PAI), Barratt's Impulsivity Scale (BIS), and the Acceptance and Action Questionnaire (AAQ). Paired-sample t-tests compared each of the 28 individuals who met criteria for TTM to an age and gender matched individual who did not meet criteria for TTM or any Axis I condition. Significant differences were found between many of the PAI scales and subscales, impulsivity, and experiential avoidance. The TTM group displayed higher levels of pathology than the control group. The findings provide evidence that individuals with TTM demonstrate differing levels of personality characteristics compared to individuals without TTM and that treatment may benefit from acknowledging and targeting these areas.

    • "Additionally, the Trichotillomania Diagnostic Interview (TDI; Rothbaum & Ninan, 1994) was employed for obtaining TTM diagnosis. The MGH-HPS has demonstrated adequate psychometric properties (Diefenbach et al., 2005; Keuthen et al., 1995; O'Sullivan et al., 1995). It consists of seven items that are scored on a 0–4 Likert scale, resulting in total scores ranging from 0 to 28, with higher scores indicating greater hair pulling severity. "

    ABSTRACT: The Massachusetts General Hospital Hairpulling Scale (MGH-HPS) and the NIMH Trichotillomania Severity Scale (NIMH-TSS) are two widely used measures of trichotillomania severity. Despite their popular use, currently no empirically-supported guidelines exist to determine the degrees of change on these scales that best indicate treatment response. Determination of such criteria could aid in clinical decision-making by defining clinically significant treatment response/recovery and producing accurate power analyses for use in clinical trials research. Adults with trichotillomania (N = 69) participated in a randomized controlled trial of psychotherapy and were assessed before and after treatment. Response status was measured via the Clinical Global Impressions-Improvement Scale, and remission status was measured via the Clinical Global Impressions-Severity Scale. For treatment response, a 45% reduction or 7-pointraw score change on the MGH-HPS was the best indicator of clinically significant treatment response,and on the NIMH-TSS, a 30–40% reduction or 6-point raw score difference was most effective cutoff. For disorder remission, a 55–60% reduction or 7-point raw score change on the MGH-HPS was the best predictor, and on the NIMH-TSS, a 65% reduction or 6-point raw score change was the best indicator of disorder remission. Implications of these findings are discussed.
