Learning Objective 1: learn the process of psychometric validation of an instrument across different languages.
Learning Objective 2: learn the psychometric characteristics of the Chinese Version of the Decisional Balance Scale (CDBS)
Methods: This is a secondary data analysis study. The data used in this study was from an intervention study that examined the effects of a smoking prevention intervention with native Taiwanese children aged 9 to 11. The CDBS was administered to 796 children in grades 4-5 recruited from all primary schools of 2 native Taiwanese reserved areas in central
Results: Cross validation method was used in this study. Exploratory factor analysis from half of sample size yielded two components for the CDBS accounting for 55.8% of the total variance, with alphas of .85 and .82 for the subscales. Item-to-subtotal correlation coefficients for the subscales were above 0.63. The results from confirmatory factor analysis with the rest of half sample indicated that the two-factor structure was the best fit for the CDBS when it was used with native Taiwanese adolescents (CFI = 0.97). The contrasted group approach affirmed the construct validity of the Pros and the Cons of the CDBS. Validity and reliability of the CDBS was supported by the psychometric test results of this study
Conclusion: The results of this study suggested that the CDBS was applicable to and congruent with the culture of the native Taiwanese adolescents in assessing smoking attitudes. However, the CDBS needs to be tested with different populations and settings in the future study.
