An epidemiological study of trichotillomania in Israeli adolescents.
To determine the prevalence of trichotillomania and comorbid psychopathology in nonreferred adolescents.
Using a questionnaire and interview, 794 Israeli 17-year-olds were screened for current and past hair-pulling and comorbid psychopathology.
Eight current or past hair-pullers (5 male, 3 female) were identified, yielding a lifetime prevalence of hair-pulling of 1%. Four subjects reported current hair-pulling (point prevalence of 0.5%). None of these reported alopecia, distress, or tension before pulling ; only two reported relief after pulling.
Thus, none met the full DSM-III-R criteria for trichotillomania.
Four subjects reported past but not current hair-pulling, with bald spots in two cases.
Three of the four current hair-pullers had significant obsessive-compulsive symptoms, a significantly elevated rate compared to the entire screened population.
Two subjects with obsessive-compulsive disorder also had generalized anxiety disorder and, in one case, chronic simple vocal tics.
Hair-pullers did not differ significantly from non-hair-pullers in IQ, physical fitness, and overall competency, or prevalence of other comorbid disorders.
In a community adolescent sample, only 25% of hair-pullers reported resulting bare spots and none endorsed both rising tension and subsequent relief.
The prevalence of obsessive-compulsive symptoms was significantly elevated in these nonreferred hair-pullers.
