The Dyadic Almost Perfect Scale-Revised(Dyadic APS-R)is a self-report measure of perfectionism. The present study was intended to examine the psychometric properties of the Japanese version of the Dyadic APS-R. Japanese university students (213) completed the Japanese version of the Dyadic APS-R along with measures of mental health outcomes (self-efficacy and depression). Exploratory factor analysis revealed two factors: High Standards and Order, and Discrepancy. A reliability estimate of internal consistency of High Standards and Order, and Discrepancy was high. Confirmatory factor analysis of the Dyadic APS-R in another group of Japanese university students (108) supported the existence of 2 perfectionism factors. Cluster analysis using the two subscales of the Dyadic APS-R yielded 3 clusters: Adaptive perfectionists, maladaptive perfectionists, non-perfectionists.Adaptive perfectionists characterized by high Standards and Order scores, and low Discrepancy scores had higher scores on self-efficacy and lower scores on depression than those of maladaptive perfectionists and even of non-perfectionists.Distinguishing adaptive perfectionists from maladaptive perfectionists is discussed in the context of psychological functioning and further research.
