Objective The college and university students' physical exercise behavior scale has been de-veloped. Methods Baaed on the theory of planning behavior,after investigation and analysis,a questionnaire was made to test 1180 students from some colleges and universities in Changjiang Delta area. Its reliability and validity was tested,and confirmatory factor analysis was carried out. Results The scale consists of 4 factors: behavioral intention,subjective criterion,cognitive behavior,and integrative attitude. Its retest reliability was 0.920, correla-tion coefficient of the factors between 0.732 and 0.854 ,and the total scale Cronbach α 0.931. The correlated co-efficients between subseales and total scales range 0.455～0.785 ;the IFI, CFI,and NFI fit indices of the four di-mensions were over 0.9 ;RMSEA 0.042. Conclusion The reliability and validity of the scale are suitable as an effective tool to test university students' sports exercise behavior.
