Prevalence, gender correlates, and co-morbidity of trichotillomania
Open accessAbstract
Trichotillomania is a mental health condition characterized by repetitive pulling out of one's hair, often leading to functional impairment and/or distress. A convenience sampling of 10,169 adults, aged 18-69 years, representative of the general US population, completed a survey to establish occurrence of trichotillomania, other mental health concerns, and impact of the illness. 175 (1.7%) identified as having current trichotillomania. Rates of trichotillomania did not differ significantly based on gender (1.8% of males and 1.7% of females). The mean age of onset for trichotillomania was 17.7 years. The mean age of onset differed significantly for males (mean 19.0 years) versus females (mean 14.8 years (p = 0.020). The average amount of distress reported due to trichotillomania was relatively high, and 79% of people with trichotillomania had one or more mental health comorbidities, the most common being anxiety/depressive disorders, OCD, PTSD, and ADHD. This study suggests trichotillomania is relatively common in the general population and typically characterized by moderate-high distress and high rates of comorbidity.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
