Evaluation on reliability and validity of Steinberg Parenting Scale, Chinese revision

Objective To provide scientific evidence for the general use of the Steinberg Parenting Scale in China and to revise Steinberg Parenting Scale in Chinese and to assess its reliability and validity.Methods Firstly,each item of the scale was translated into Chinese and administered to 356 primary and secondary school students in Baoding city,and then the items of the scale were selected based on the results of item analysis and exploratory factor analysis(EFA).Secondly,formal test was conducted among 7 460 primary and middle school students from 18 cities and tow ns in 7 provinces to test the validity and reliability of the scale.Results A three-factor model (involvement,psychological autonomy-granting,and strictness/supervision) including 21 items was found in EFA with a cumulative variance contribution rate of 37.9%.The fit indexes in confirmatory factor analyses were as follow ing:root mean square error of approximation (RMSEA)=0.051,comparative fit index(CFI)=0.923,nonnormed fit index (NNFI)=0.913.The Cronbach's α was 0.71 for involvement,0.69 for psychological autonomy granting,and 0.71 for strictness/supervision,respectively.The split-half index was 0.70 for involvement,0.66 for psychological autonomy granting,and 0.75 for strictness/supervision,respectively.The correlation coefficient betw een each subscale and total scale was 0.76 for involvement,0.59 for psychological autonomy granting,and 0.54 for strictness/supervision,respectively.Conclusion The results suggest that the Chinese version of Steinberg Parenting Scale has acceptable validity and reliability and can be applied in the study in China.
