The present study examined the factor structure and measurement invariance of the Behavioral Inhibition System/Behavioral Approach System (BIS/BAS) scales parent-report in children and adolescents ( = 1,444, 58% girls) across age (Group 1, 2-5 years; Group 2, 6-9 years; Group 3, 10-13 years; Group 4, 14-18 years old) and gender. The results consistently underscored a four-factor structure, resembling the original factor structure, with one BIS-factor and three BAS-factors. Multigroup confirmatory factor analysis showed full measurement invariance across gender as well as across Group 1 and 2, and Group 2 and 3. Strong measurement invariance was found across Group 3 and 4, Group 1 and 3, and Group 2 and 4. Configural and metric invariance was found across Group 1 and 4. Hence, mean-level BIS/BAS scores can be compared across gender and age although comparison between preschool children (Group 1) and late secondary school children (Group 4) should be done with caution.
本研究考察了儿童和青少年（n=1444，58%为女性）父母报告的行为抑制系统/行为趋近系统（BIS/BAS）量表的因子结构和测量不变性，按年龄（第 1 组，2-5 岁；第 2 组，6-9 岁；第 3 组，10-13 岁；第 4 组，14-18 岁）和性别进行分组。结果一致表明存在一个四因子结构，类似于原始的因子结构，包括一个 BIS 因子和三个 BAS 因子。多群组验证性因子分析表明，性别以及第 1 组和第 2 组、第 2 组和第 3 组之间存在完全测量不变性。在第 3 组和第 4 组、第 1 组和第 3 组以及第 2 组和第 4 组之间发现了很强的测量不变性。在第 1 组和第 4 组之间发现了组态和度量不变性。因此，尽管应该谨慎地比较学龄前儿童（第 1 组）和中学后期儿童（第 4 组）之间的 BIS/BAS 得分，但可以在性别和年龄之间比较 BIS/BAS 得分的平均值。
