【Abstract】 Objective:To verify the cross-temporal measurement equivalence of the Simplified Chinese version of the Physical Activity Dependence Scale(PADS) in the Chinese university student population.Methods:A survey was conducted among 2225 university students in Leshan and Chengdu,Sichuan Province,with an interval of six months,using the PADS for two follow-up surveys on the same cohort.Results:(1) The factor loadings for each dimension in the T1 period ranged from 0.674 to 0.930,and from 0.706 to 0.971 in the T2 period.The Comparative Fit Index(CFI) and Tucker-Lewis Index(TLI) for the PADS were all above 0.9 in both T1 and T2observation periods,with the Root Mean Square Error of Approximation(RMSEA) below 0.08;(2) In the configural invariance test,all model fit indices were satisfactory:CFI=0.915,TLI=0.915,Bayesian Information Criterion(BIC)=2400.258,Standardized Root Mean Square Residual(SRMR)=0.048,RMSEA=0.061,thus establishing configural invariance;(3) The weak invariance results showed that both ?CFI and ?TLI were-0.002,far less than the defined range of 0.01,with BIC and RMSEA being 2432.910 and 0.059,respectively,both of which had decreased by 32.652 and 0.002 respectively,indicating that all decay indices were within the model equivalence range;(4) The strict invariance of the scalar model showed that ?CFI and ?TLI were both-0.003,with BIC and RMSEA being 2424.652 and 0.058 respectively,a decrease of 2.486 and 0.000 respectively compared to the strong invariance model;(5) The cross-time invariance of the latent variable variance showed that both ?CFI and ?TLI were 0.000,with BIC and RMSEA being 2404.356 and 0.058 respectively,a decrease of20.296 and 0.000 respectively compared to the strict invariance model;(6) The cross-time stability of the model showed that both ?CFI and ?TLI were-0.007,with BIC and RMSEA being 2315.566 and 0.058 respectively,a decrease of 88.79 and 0.000 respectively compared to the model of factor variance invariance;(7) The cross-time invariance of the latent variable mean showed that ?CFI and ?TLI were 0.009 and 0.036 respectively,with BIC and RMSEA being 131.382 and 0.052 respectively,a decrease of 31.382 and 0.006 respectively compared to the model of factor covariance invariance.Conclusion:The five-factor model of the Simplified Chinese version of the PADS demonstrates cross-temporal measurement equivalence.更多还原
