AbstractIntroductionThe perfectionistic self‐presentation scale (PSPS)–junior form is a self‐report questionnaire used to measure perfectionistic self‐presentation in children and adolescents. It consists of 18 items and 3 subscales, including perfectionistic self‐promotion, non‐display of imperfection, and nondisclosure of imperfection.MethodsThe present study aimed to determine the psychometrics of the Persian version of the PSPS. A descriptive study was conducted on 345 samples (269 girls) who responded to the questionnaire.ResultsThe findings confirmed the internal consistency and composite reliability (CR) of this scale (CR = 0.744). Further, the Persian PSPS has acceptable face and content validities. Construct and convergent validities were also measured and confirmed by confirmatory factor analysis. The correlational analysis of the research variables showed that the PSPS is positively correlated with the Child‐Adolescent Perfectionism Scale (0.566) and the children's and adolescents’ dysfunctional attitudes scale (0.420).ConclusionOverall, the results indicated that the Persian version of the PSPS has acceptable psychometrics and can yield accurate results in Iranian samples.
