ABSTRACT Trichotillomania (TTM) is a chronic impulse control disorder characterized by repetitive hair-pulling resulting in alopecia. Although this condition is frequently observed in children and adolescents, research on pediatric TTM has been hampered by the absence of validated measures. The aim of the present study was to develop and test a new self-report measure of pediatric TTM, the Trichotillomania Scale for Children (TSC), a measure that can be completed by children and/or their parents. One hundred thirteen children meeting self-report criteria for TTM, and 132 parents, provided data over the internet. An additional 41 child-parent dyads from an outpatient clinic also provided data. Replicated principal components analysis, with elimination of poorly-loading items, yielded two components, which we labeled Severity (five items) and Distress/Impairment (seven items). The TSC total score and subscales showed adequate internal consistency and test-retest reliability. Parent-child agreement was good in the internet sample, but more modest in the clinic sample. Children's TSC scores correlated significantly with other measures of TTM severity, although some exceptions were noted. Parents' TSC scores correlated significantly with other measures of parent-rated TTM severity in the internet sample, but showed more attenuated relationships with child- and interviewer-rated TTM severity in the clinic sample. The present results suggest that the TSC may be a useful measure of TTM for child and adolescent samples, although additional clarification of convergent validity is needed.

    ABSTRACT: Trichotillomania, or chronic hairpulling, is a common condition that affects primarily women. The disorder can cause significant psychosocial impairment and is associated with elevated rates of psychiatric comorbidity. In this article, the phenomenology, etiology, assessment, and treatment of the disorder are discussed.

    ABSTRACT: Trichotillomania (TTM) often first presents in adolescence, a developmental period marked by vulnerability in body image. To date, no one has studied the relationship between this disorder and body esteem.

    ABSTRACT: Few randomized controlled trials (RCTs) exist examining the efficacy of behavior therapy (BT) or serotonin reuptake inhibitors (SRIs) for the treatment of trichotillomania (TTM), with no examination of treatment moderators. The present meta-analysis synthesized the treatment effect sizes (ES) of BT and SRI relative to comparison conditions, and examined moderators of treatment. A comprehensive literature search identified 11 RCTs that met inclusion criteria. Clinical characteristics (e.g., age, comorbidity, therapeutic contact hours), outcome measures, treatment subtypes (e.g., SRI subtype, BT subtype), and ES data were extracted. The standardized mean difference of change in hair pulling severity was the outcome measure. A random effects meta-analysis found a large pooled ES for BT (ES= 1.41, p< 0.001). BT trials with greater therapeutic contact hours exhibited larger ES (p= 0.009). Additionally, BT trials that used mood enhanced therapeutic techniques exhibited greater ES relative to trials including only traditional BT components (p= 0.004). For SRI trials, a random effects meta-analysis identified a moderate pooled ES (ES= 0.41, p= 0.02). Although clomipramine exhibited larger ES relative to selective serotonin reuptake inhibitors, the difference was not statistically significant. Publication bias was not identified for either treatment. BT yields large treatment effects for TTM, with further examination needed to disentangle confounded treatment moderators. SRI trials exhibited a moderate pooled ES, with no treatment moderators identified. Sensitivity analyses highlighted the need for further RCTs of SRIs, especially among youth with TTM.
