Measurement Invariance of the Self-Description Questionnaire II in a Chinese sample

Studies on the construct validity of the Self-Description Questionnaire II (SDQII) have not compared the factor structure between the English and Chinese versions of the SDQII. By using rigorous multiple group comparison procedures based upon confirmatory factor analysis (CFA) of measurement invariance, the present study examined the responses of Australian high school students (N = 302) and Chinese high school students (N = 322) using the English and Chinese versions of the SDQII, respectively. CFA provided strong evidence that the factor structure (factor loading and item intercept) of the Chinese version of the SDQII in comparison to responses to the English version of the SDQII is invariant, therefore it allows researchers to confidently utilize both the English and Chinese versions of the SDQII with Chinese and Australian samples separately and cross-culturally
