Revision of the basic needs satisfaction in general scale(Chinese vision)

Objective To revise and test the reliability and validity of the Chinese vision of the Basic Needs Satisfaction in General Scale (BNSG-S). Methods Totally 6366 youth workers from 5 organizations were recruited with stratified sampling method. Participants were asked to complete the Chinese vision of BNSG-S. Item analysis was conducted to identify valid items and revise the scale. Then the construct validity of the revised scale was tested through exploratory and confirmatory factor analysis(EFA & CFA). The criterion validity was tested with the Index of Well-being Scale. Finally the reliability of the scale was examined. Results The revised scale consists of 15 items with 4 factors- satisfied state of autonomy need, blocked state of autonomy need, satisfied state of relatedness need, blocked state of relatedness need. The four factors explained 63.95% of the total variance. Besides, the CFA results demonstrated a satisfactory construct validity of the scale (RMSEA=0.056, NFI=0.97, NNFI=0.96, CFI=0.97). The correlation coefficients between the scale and the Index of Well-being Scale was 0.50 (P<0.01) and each factor was significantly correlated to the Index of Well-being Scale. The Cronbach's α coefficients of the Chinese vision of BNSG-S was 0.76, and those of its 4 factors were 0.80, 0.67, 0.83 and 0.80 respectively. Conclusion The Chinese vision of BNSG-S with 4 factors has good reliability and validity, demonstrating it a valid tool to measure Chinese basic needs satisfaction.
