Comorbidity of psychiatric and dermatologic disorders with skin picking disorder and validation of the Skin Picking Scale Revised for Brazilian Portuguese.

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. Self-report 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 (?2 = 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.

Project description:BackgroundHIV-related stigma, or the degree to which people living with HIV endorse negative stereotypes associated with HIV, is associated with poor continuum of care outcomes. We translated the 12-item Short HIV Stigma scale and evaluated its psychometric properties in a Brazilian context with regard to construct validity and reliability.MethodsThe first step included translation, back-translation, evaluation, peer review, and pre-testing of the Short HIV Sigma scale developed by Reinius et al. (Health Qual Life Outcomes 15(1):115, 2017). The second step involved piloting the scale in three convenience samples of adults recruited online through advertisements on different platforms: Grindr (October/2019) and Hornet (February-March/2020), geospatial network apps for sexual encounters for gay, bisexuals and other men who have sex with men, and social media apps (Facebook and WhatsApp, October/2019). The psychometric evaluation included confirmatory factor analysis, differential item functioning using the Multiple-Indicator Multiple-Cause model, and correlations between subscale scores and antiretroviral treatment use and adherence. Reliability was assessed using Cronbach's alpha, and ordinal alpha and omega from the polychoric correlation matrix.ResultsIn total, 114, 164, and 1824 participants completed the measure items through Grindr, social media, and Hornet, respectively. We confirmed a 4-factor structure with factors for personalized stigma (3 items), disclosure concerns (3 items), concerns with public attitudes (3 items), and negative self-image (3 items). Small differential item functioning with respect to sample was found for one item ("I feel guilty because I have HIV"), which did not substantively influence estimates of latent factor scores. Grindr and Hornet's participants scored significantly higher than social media participants on all factors except personalized stigma. Higher subscale scores correlated with antiretroviral treatment use among participants from Hornet and with lower treatment adherence in participants from Grindr and Hornet. Reliability as measured by Cronbach's alpha, ordinal alpha and omega were 0.83, 0.88 and 0.93 for the entire scale.DiscussionThe Brazilian Portuguese version of the Short HIV Stigma scale had satisfactory psychometric properties with present results suggesting that scores from different samples may be compared without concern that measurement differences substantively influence results though further studies with greater representation of women and heterosexual men are warranted.
