Abstract

BACKGROUND: Trichotillomania (TTM) remains understudied in children. Adult research suggests that TTM is accompanied by significant depression, anxiety, and functional impairment. The purpose of this study is to examine the occurrence of depression and anxiety in a relatively large sample of youth with TTM and the extent to which these symptoms mediate the relationship between TTM severity and associated impairment. METHODS: The study utilized data from the Child and Adolescent Trichotillomania Impact Project (CA-TIP), an internet-based sample of 133 youth aged 10-17 (inclusive) with TTM. RESULTS: Over 45% of children with TTM endorsed depressive symptoms and 40% endorsed anxiety symptoms in excess of one standard deviation (SD) above published community norms. More remarkably, 25% of our sample reported depressive and 20% reported anxiety symptoms in excess of 2 SD above these norms. Older participants reported more symptoms of depression and anxiety than younger ones; age of onset (children with later onset), but not duration of illness, was predictive of higher reports of both depressive and anxiety symptoms. Neither depressive nor anxiety symptoms were related to pulling site. Depressive symptoms partially mediated the relationship between TTM severity and functional impairment. CONCLUSIONS: Based on an internet sample recruited from the homepage of the Trichotillomania Learning Center, data from this study suggests that symptoms of depression and anxiety may be pervasive among youth with TTM and likely impact functional impairment. Longitudinal studies using directly assessed samples are needed to replicate and extend these findings.

  • In childhood, sex distribution in trichotillomania has been found to be equal.

    “In childhood, sex distribution has been found to be equal.[10]”

    From Trichotillomania (hair pulling disorder) (2019) · cites this paper as [10]

    The Participants section (page unavailable) reports 96 girls and 16 boys among the 133 youth studied; sex was unrecorded for 21. This sample is not evidence of an equal sex distribution in childhood and instead shows a marked female predominance among participants whose sex was recorded. (LLM, conf=0.86)

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.
