This study is aimed at develop a college basketball player of social support, school Adjustment and participate motivation scale. Object of study is the 2013 academic year college basketball league player. Statistical analysis of the resulting data: (1) The social support scale, cumulative variance explained of 67.53 %, has five facets total of 24 questions included "family support", "teammate support", "support the students", "teacher support" and "coach support". (2) The school Adjustment scale, cumulative variance explained of 62.18 %, has four facets total of 17 questions including "peer adapt", "learning to adapt", "learning to adapt" and "teacher-student interaction". (3) The participate motivation scale, cumulative variance explained of 70.20 %, has five facets total of 21, questions including 'healthy fitness", "need for achievement", "social demand", "avoid stimulating" and "technical requirements". The Cronbach's α of subscales ranged from .709 to .936. Shows the scale has acceptable construct validity and reliability. Then using confirmatory factor analysis test the goodness of fit hypothesis model. Statistical analysis of the resulting data: (1) The social support scale results show an acceptable goodness of fit (χ2=579、χ^2/df=3.05、GFI=0.9、SRMR=0.051、RMSEA=0.065、NNFI=0.97、CFI=0.98、PNFI=0.77、PGFI=0.68). (2) The school adaptation scale (χ^2=42.75、χ^2/df=3.54、GFI=0.97、SRMR=0.021、 RMSEA=0.070、NNFI=0.99、CFI=0.99、PNFI=0.54、PGFI=0.50). (3) The participation motivation scale result after correction exhibit acceptable goodness of fit (χ^2=56.47、χ^2/df=2.46、GFI=0.97、SRMR=0.030、RMSEA=0.057、NNFI=0.99、CFI=0.99、PNFI=0.63、PGFI=0.50). This scale may provide researchers study college basketball as a reference in the future.
