Personality characteristics and experiential avoidance in Trichotillomania: Results from an age and gender matched sample

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.
