Pathological skin picking (PSP) and trichotillomania (TTM) are disorders characterized by distress and impaired functioning. This study sought to compare quality of life for individuals with PSP or TTM. PSP or TTM subjects completed the quality of life inventory and valid and reliable measures of clinical severity. Analyses included group comparisons of PSP, TTM and healthy controls, and within-group comparisons. 59 subjects with PSP (mean age 33.4 ± 12.8; 88.1% female), 70 with TTM (mean age 34.8 ± 12.0; 88.6% female), and 25 healthy controls (mean age 31.3 ± 10.1; 80% female) were included. PSP subjects reported more psychosocial impairment compared to TTM subjects (p=0.013). Both PSP and TTM subjects had lower quality of life scores compared to healthy controls. Quality of life was not associated with symptom severity. Larger studies should examine further the impact PSP and TTM have on quality of life as well as the role quality of life itself plays in the severity and duration of illness.
