Relations of the german almost perfect scale-revised and short almost perfect scale with the big five personality facets

Abstract The Almost Perfect Scale-Revised (APS-R) and its short form (SAPS) are among the most-established multidimensional perfectionism measures. Yet, investigations into APS-R/SAPS nomological networks have mainly been limited to level of broader personality traits. This reliance on trait-level associations hampers conceptual understanding traits by masking more complex relations with specific cognitive, emotional, behavioral tendencies (personality facets). In this study, we validated German versions APS-R SAPS assessed their Big Five facets in two samples ( N Sample 1 = 305 university students; 2 467 community adults). Both scales displayed satisfactory psychometric properties, convergent criterion-related validity. Analyses revealed nuanced patterns relations. These findings provide new insights facilitate distinction between subscales.
