Abstract:
In the present study, we examined the psychometric properties of the Skin Picking Impact Scale ( SPIS ; Keuthen, Deckersbach, Wilhelm et al ., 2001), a 10 item self‐report questionnaire designed to assess the psychosocial impact of skin picking disorder ( SPD ). Participants were 650 individuals who met criteria for SPD in an online survey. Exploratory and confirmatory factor analyses demonstrated a unitary factor structure with high internal consistency ( α = 0.94). Consequently, we constructed an abbreviated 4‐item version that retained good internal consistency ( α = 0.87) and a robust factor structure. Both the short and the full versions demonstrated discriminant and convergent/concurrent validity. In conclusion, the findings indicate that both versions are psychometrically sound measures of SPD related psychosocial impact; however, some potential limitations of the full scale are discussed.
