The purpose of this study was to conduct psychometric testing on the Chinese version of the decisional balance scale (CDBS) with Taiwanese seventh, eighth,and ninth graders who were recruited from the Taipei metropolitan area. A random cluster sampling method was used with 554 adolescents between the ages of 13 and 17 years. Factor analysis procedures showed two components, Pros and Cons, accounting for 74.32% of the total variances and contrasted group comparisons affirmed the construct validity of the Pros, the Cons, and the CDBS. Item-to-subtotal correlation coefficients for the two subscales, the Pros and Cons, were greater than .50 and their reliability was supported by Cronbach's alpha coefficients, .87 and .91, respectively. The validity and reliability of the CDBS suggested that the CDBS was applicable to and congruent with the culture of the Taiwanese adolescent's smoking behavior. Further validation of the CDBS scale with different populations and larger sample size is suggested.
本研究旨在对决策平衡量表中文版（CDBS）进行心理测量测试，该量表施用于从台北都会区招募的台湾初一、初二和初三学生。采用随机整群抽样法，选取了554名年龄在13至17岁之间的青少年。因子分析程序显示有两个分量表，即“益处”和“弊端”，它们占总方差的74.32%，对比组比较证实了“益处”、“弊端”及CDBS的结构效度。两个分量表“益处”和“弊端”的项目与总分相关系数均大于0.50，其信度分别得到克朗巴哈α系数0.87和0.91的支持。CDBS的效度和信度表明，CDBS适用于台湾青少年吸烟行为的文化背景且与之相符。建议对不同人群和更大样本量的CDBS量表进行进一步验证。
