<p>To assess the reliability and validity of the Dietary Supplement Choice Questionnaire (DSCQ) to capture dietary supplement choice motives among Japanese college athletes. The cross-sectional study was performed in 2014. This study recruited 1,451 college athletes from sports-oriented clubs at the University of Tsukuba, Japan. The participants completed the DSCQ, health literacy, and subjective economic status; part of the participants completed a test-retest (n=378). A sample of 975 participants (28.0% female) included in the analysis. The DSCQ was developed through factor analysis. Seven factors emerged, and were labelled “popularity,” “functionality,” “price,” “taste,” “convenience,” “antidoping” and “familiarity.” Mostly acceptable reliability was seen across seven DSCQ factors (the internal consistency, Cronbach’s α=0.62-0.85; the test-retest reliability coefficients, r=0.62-0.82), whereas convergent validity for price and antidoping factors was provided by significant associations with economic status and literacy (p<0.01). Findings showed reasonable evidence of reliability and validity of the DSCQ and provided the opportunity to comprehensively assess dietary supplement choice motives among Japanese college athletes.</p>
