46-5 Reliability, Validity, and Measurement Invariance of the Brief Chinese Version of Psychological Well-Being Scale among College Students
The two aims of this research were to obtain reliability and validity information of Li's (2014) 18-item brief Chinese version of the Psychological Well-Being Scale across samples, and to test its measurement invariance across time. Three samples of college students were recruited in the study. They were named as sample I, sample II, and common sample, in which 442, 349, and 394 students, respectively. Data were analyzed using structural equation modeling techniques. Results showed that theoretical framework of six-factor oblique model had good model-fits. Cronbach's α coefficients ranged from .73 to .87 for subscale scores, and was .91 for the total score; 2 ~ 3 weeks test-retest reliability coefficients of subscale scores ranged .59 ~ .65, and was .70 for the total score. Based on the 6-factor model, factor loadings were among .65 ~ .92 providing convergent validity , and interfactor correlations were ranging .30 ~ .72 offering discriminant validity . Besides, cross validation was supported. Furthermore, metric invariance and scalar invariance existed across groups in the measurement equivalence tests; therefore it ensured that the scale can be compared on its constructs across multiple measurement times , including comparisons in interfactor correlations and latent means.
