Abstract
Abstract
Background: In this study, we aimed to perform the validity and reliability study for Turkish version of Skin Picking Impact Scale (SPIS).
Methods: This study included 80 patients diagnosed with SPD according to DSM-5 diagnostic criteria. Patients were given Sociodemographic Data Form, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Short Form-36 Quality of Life Scale (SF-36), Yale-Brown Obsessive Compulsive Scale Modified for Neurotic Excoriation (NE-YBOCS) and Turkish version of SPIS. Cronbach’s alpha coefficient and item-total correlation were examined for the reliability of the scale. Confirmatory factor analysis (CFA) was used to examine the factor structure of the scale and ROC (Receiver Operating Characteristics) was performed to the discriminatory validity analysis.
Results: Cronbach’s alpha internal consistency coefficient was determined to be 0.942. Item-total correlation coefficients of all questions ranged between 0.665 and 0.849. The one-factor structure showed a good model fit in CFA. Good correlations were observed between SPIS and number of sites of picking (r=0.265, p=0.037), duration of skin picking per day (r=0.453, p<0.001), NE-YBOCS score (r=0.509, p<0.001), BDI (r=0.273, p=0.014), and total scores for SF-36 subscales (r= -0.262, p=0.019). SPIS was determined to be a good scale for distinguishing SPD patients and controls.
Conclusion: Our study shows that the ten-item version of SPIS, which consists of a single factor, can be used in a reliable and valid way for Turkish population.
Keywords: Skin picking disorder, scale, validity, reliability.

Key words: Skin picking disorder, scale, validity, reliability.
