Establishing the reliability and validity of an instrument is essential for conducting research, as accurate measurement is fundamental to the research process. It is a challenging task to use an instrument on a sample from a different culture and language than the original population. Although the Chinese language version of the Decisional Balance Scale (CDBS) has been established with sound psychometric properties, the reliability and validity of this instrument has not been evaluated in native Taiwanese populations.


To conduct psychometric validations for the CDBS with native Taiwanese children aged 9 to 11.


This research project was designed as a descriptive cross-sectional study with population survey. The CDBS was administered to 796 children in grades 4-5 recruited from all elementary schools of 2 native Taiwanese reserved areas in mid Taiwan.


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.


The results of this study suggest that the CDBS is a valid and internally consistent instument. It is also feasible to use this instrument to study smoking attitudes among native Taiwanese adolescents.

Learning Objectives:
Describe the process of psychometric validation of an instrument in a different language. Discuss at least two psychometric characteristics of the Chinese Decisional Balance Scale (CDBS) with native Taiwanese adolescents.
