German translation of the Revised Physical Self-Perception Profile Competence (PSPP-R Competence)

Abstract

This paper examines the validity of the competence scale of the Revised Physical Self-Perception Profile (PSPP-R Competence) in a large German sample of 1,007 predominantly female participants by assessing construct validity, discriminant and criterion validity, and reliability. The PSPP-R Competence measures four factors: Body Attractiveness, Physical Strength, Sports Competence, and Physical Condition. Confirmatory factor analyses confirmed the hypothesized correlated four-factor structure and offered support for a hierarchical factor structure. Discriminant and criterion validity analyses offered insight into the nomological net and were in line with theoretical considerations. Reliability of all subscales was estimated using Cronbach’s α and found to be good to excellent ranging from .84 to .92. Overall, this study provides support for a good adaptation of the PSPP-R in the German language and enriches previous validation studies focused mainly on factorial validity by adding discriminant and concurrent validity estimates.
