dc.description.abstract | Objective: Skin picking disorder (SPD) affects up to 5.4% of the population. Less than half of patients are correctly diagnosed and treated. Developing tools to recognize SPD can help professionals and patients alike. This trial aimed to validate the Skin Picking Scale-Revised (SPS-R) for the Brazilian population and assess the psychiatric and dermatological comorbidities of patients with SPD. Methods: Brazilians with a primary diagnosis of SPD, 18 years or older, were recruited from a community sample by media advertising and evaluated by a dermatologist and a psychiatrist. Selfreport instruments were used: SPS-R, Dermatology Life Quality Index (DLQI), General Anxiety Disorder-7 (GAD-7), and Patient Health Questionnaire-9 (PHQ-9). Confirmatory factor analysis (CFA) was performed to evaluate the SPS-R, and Pearson correlation (r) was used to assess the relationship between instruments. Results: Overall, 124 patients were included. The SPS-R demonstrated good internal consistency (Cronbach’s coefficient = 0.84). CFA found a good fit to the model according to all indices (w2 = 29.67; degrees of freedom [df] = 19; p = 0.056; root mean square error of approximation [RMSEA] = 0.067; comparative fit index [CFI] = 0.969; non-normed fit index [NNFI] = 0.954). SPS-R correlated with DLQI (r = 0.73), GAD-7 (r = 0.51), and PHQ-9 (r = 0.43). The sample had a high prevalence of psychiatric disorders, mainly generalized anxiety disorder (62.1%) and current (32.3%) and past (37.1%) depressive episodes. Conclusion: The Brazilian version of the SPS-R presents good psychometric properties. The severity of SPD is related to severity of depression, anxiety, and impairment in quality of life.
