Reliability and validity of the Chinese version of the student nurse stress index scale ( SNSI-CHI) / 中华行为医学与脑科学杂志

ABSTRACT

Objective To test the reliability and validity of the Chinese Version of the Student Nurse Stress Index Scale ( SNSI-CHI ) among Chinese nursing students. Methods A random sampling method was used to collect 1100 nursing students who were from two medical universities of Henan Province, China,and SPSS 17. 0 and AMOS 17. 0 software were used. Results The average total score of SNSI-CHI was 58. 46±13. 90. The Cronbach's α was 0. 886,the test-retest intra-class correlation coefficient( ICC) of SNSI-CHI was 0. 996 (95％CI0. 992-1. 000,P<0. 01). The item-to-total correlations ranged from 0. 351 to 0. 664 ( all P<0. 01) . The content validity index( CVI) was 0. 954. The result of exploratory factor analysis ( EFA) was that three factors together explained 75. 013％ of the total variances,and the confirmatory factory analysis( CFA) also indicated a good fit (χ2/df=1. 347,GFI=0. 956,AGFI=0. 945,RMR=0. 032,RMSEA= 0. 025, NFI=0. 974, IFI=0. 993, TLI=0. 992, CFI=0. 993 ) . Criterion-related validity was between 0. 330 and 0. 903 ( all P<0. 01) . Conclusion The SNSI-CHI is proved to be reliable and valid in China, and it can be used to measure the stress of Chinese nursing students.
