The Profile of Mood State (POMS) Questionnaire was designed to measure athletes' mood in sport situations. The purpose of this study was to test the construct validity of the measurement model assumed to underlie POMS by using confirmatory factor analysis. Subjects were 539 college students. LISREL 8.3 was used to analyze the data. The results of the confirmatory factor analysis indicated that measures of overall fit for the hypothetical seven-factor structure of the POM was acceptable(χ^2=167.89, p=.l4), RMSEA=.016, GFI=.97, AGFI=.95, NFI=.98, RMR=.02, S-RMR=.02). The results indicated that the Chinese version of POMS has appropriate construct validity and can be utilized to assess the mental attitude in sport.
