Article Synopsis
  • * The study aimed to understand the patterns of skin picking in real-time using ecological momentary assessment (EMA), focusing on the characteristics and intensity of skin picking episodes and differentiating between automatic and focused behaviors.
  • * A sample of 57 participants (mostly female, average age 29) completed a total of 3758 EMA assessments, revealing that they experienced an average of 2.57 skin picking episodes per day, typically lasting between 10 and 30 minutes.

Hair pulling disorder (HPD; trichotillomania) and skin picking disorder (SPD; excoriation disorder) are understudied psychiatric disorders. The aim of this study was to examine the prevalence and correlates of HPD and SPD in an acute psychiatric sample. Semistructured interviews and self-report measures were administered to patients in a psychiatric partial hospital (N = 599).

Body-focused repetitive disorders (BFRBDs) are understudied in youth and understanding of their underlying mechanisms is limited. This study evaluated BFRBD clinical characteristics, and two factors commonly implicated in their maintenance - emotion regulation and impulsivity - in 53 youth aged 11 to 17 years: 33 with BFRBDs and 20 controls. Evaluators administered psychiatric diagnostic interviews.

Background: Body-focused repetitive behaviours (BFRBs) such as skin picking and hair pulling are frequent but under-diagnosed and under-treated psychological conditions. As of now, most studies use symptom-specific BFRB scales. However, a transdiagnostic scale is needed in view of the high co-morbidity of different BFRBs.

Background: Behaviors typical of body-focused repetitive behavior disorders such as trichotillomania (TTM) and skin-picking disorder (SPD) are often associated with pleasure or relief, and with little or no physical pain, suggesting aberrant pain perception. Conclusive evidence about pain perception and correlates in these conditions is, however, lacking.

Methods: A multisite international study examined pain perception and its physiological correlates in adults with TTM (n = 31), SPD (n = 24), and healthy controls (HCs; n = 26).
