Although the Decisional Balance Scale (DBS) has been established to have sound psychometric properties, the reliability and validity of this instrument have not been evaluated in different populations.
The aim of this study was to conduct psychometric validations for the Chinese version of the DBS (CDBS).
This research project was designed as a descriptive cross-sectional study. The CDBS was administered to children in Grades 5-9 (ages 11-17 years, n = 952) recruited from elementary and junior high schools in northern Taiwan. A random cluster sampling method was used.
The pros and cons subscales were supported by Cronbach's alpha coefficients of .88 and .85, respectively. Item-to-subtotal correlation coefficients for the subscales were above .48. The results from confirmatory factor analysis, used to assess the construct validity of the CDBS, indicated that the two-factor structure was the best fit for the CDBS when it was used with Taiwanese adolescents (comparative fit index = .96). The contrasted group approach affirmed the construct validity of the pros and the cons of the CDBS. The validity and reliability of the CDBS were supported by the psychometric test results of this study.
The CDBS is congruent with the culture of Taiwanese adolescents. However, to expand the usefulness of this tool across cultures, the CDBS should continue to be tested with other Chinese-speaking populations and settings.
尽管决策平衡量表（DBS）已被证实具有良好的心理测量学特性，但该工具在不同人群中的信效度尚未得到评估。
本研究旨在对中文版决策平衡量表（CDBS）进行心理测量学验证。
本研究项目设计为描述性横断面研究。采用随机整群抽样方法，对从台湾北部中小学招募的5至9年级儿童（年龄11至17岁，n = 952）施测CDBS。
利弊分量表的克朗巴哈α系数分别为0.88和0.85。分量表的项目与总分相关系数均高于0.48。用于评估CDBS结构效度的验证性因素分析结果表明，当CDBS用于台湾青少年时，两因素结构最适合该量表（比较拟合指数 = 0.96）。对比组方法证实了CDBS利弊方面的结构效度。本研究的心理测量学测试结果支持了CDBS的效度和信度。
CDBS与台湾青少年的文化相符。然而，为了在不同文化中扩大该工具的实用性，CDBS应继续在其他华语人群和环境中进行测试。
