Revision of the basic needs satisfaction in general scale( Chinese vision) / 中华行为医学与脑科学杂志

ABSTRACT

ObjectiveTo revise and test the reliability and validity of the Chinese vision of the Basic Needs Satisfaction in General Scale (BNSG-S).MethodsTotally 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.ResultsThe 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 0.80,0.67,0.83and 0.80 respectively.ConclusionThe Chinese vision of BNSG-S with 4 factors has good reliability and validity,demonstrating it a valid tool to measure Chinese basic needs satisfaction.
