Abstract:Objective To explore the reliability, validity, and cross gender measurement equivalence of the Warwick-Edinburgh mental well-being scale(WEMWBS)in higher vocational students. Methods A survey was conducted in 1 312 higher vocational students by using WEMWBS, 10 -item Connor-Davidson resilience scale(CD-RISC-10), and 12-item general health questionnaire(GHQ-12). Results There were significant differences in the scores of each item of WEMWBS between high score and low score groups(P<0.001), and the scores of each item of WEMWBS werepositively correlated with the total score(r=0.66-0.84, P<0.001). One common factor was extracted by exploratory factor analysis, and the interpretation rate of cumulative variance was 61 . 02 %. Confirmatory factor analysis showed that χ2=455.1, df=77, CFI=0.92, TLI=0.9, RMSEA=0.09, and SRMR=0.04. The model fitting met the basic standard. The total score of WEMWBS was negatively correlated with the total score of GHQ-12(r=-0 .53 , P<0.001), but positively correlated with the total score of CD-RISC-10(r=0.84, P<0.001). Cronbach’s α of WEMWBS was 0.95 , and the retest reliability after 3 weeks was 0.68 . In the measurement invariance test, WEMWBS only conformed to morphological equivalence and weak equivalence. Conclusion The application of WEMWBS in higher vocational students has good reliability and validity, and conforms to morphological equivalence and weak equivalence.
