The present investigation demonstrated cross-cultural support for convergent and discriminant validity of the Physical Self-Description Questionnaire (PSDQ) in a multitrait-multimethod analysis of relations with responses to the Physical Self-Perception Profile (PSPP). The sample, 1,041 Turkish university students in elective physical education courses from 10 Turkish universities, provided a test of the cross-cultural generalizability of responses to these two widely used English language instruments. In support of construct validity interpretations, matching PSDQ and PSPP factors were highly correlated. However, support for the PSPP was undermined by extremely high correlations among several of its factors, due in part to a substantial method effect associated with its idiosyncratic response scale. Results based on this study with Turkish university students largely replicate and extend the findings of Marsh et al, (1994) with Australian high school students. Based on psychometric, theoretical, cross-cultural, and practical considerations, the results support the use of the PSDQ in a wide variety of research and applied settings.
