Predictors of life disability in trichotillomania
Abstract
Background Limited research has investigated disability and functional impairment in trichotillomania (TTM) subjects. This study examined the relationships between hair pulling (HP) style and severity and disability while controlling for mood severity. Disability was measured in individual life areas (work, social, and family/home life) instead of as a total disability score as in previous studies. Methods One hundred fifty three adult hair pullers completed several structured interviews and self-report instruments. HP style and severity, as well as depression, anxiety, and stress were correlated with work, social, and family/home life impairment on the Sheehan Disability Scale (SDS). Multiple regression analyses were performed to determine significant predictors of life impairment. Results Depressive severity was a significant predictor for all SDS life areas. In addition, interference/avoidance associated with HP was a predictor for work and social life disability. Distress from HP was a significant predictor of social and family/home life disability. Focused HP score and anxiety were significant predictors of family/home life disability. Conclusions As expected, depression in hair pullers predicted disability across life domains. Avoiding work and social situations can seriously impair functioning in those life domains. Severity of distress and worry about HP may be most elevated in social situations with friends and family and thus predict impairment in those areas. Final…

The rate of Excoriation disorder in this study might be below average but not outside the range of other studies (10-34%, average 20.8%).
“Differences in the rates of Excoriation Disorder between our study and that of Tung et al. (2015) might seem large, but a review by Snorrason et al. (2012) showed that comorbidity rates between HPD and Excoriation fall between 10 to 34% (average = 20.8%). Thus, our rate of Excoriation disorder might be below average, but not outside the range of other studies.”

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.
