To identify the optimal factor structure of the behavioral inhibition system/behavioral activation system (BIS/BAS) scales and to examine measurement invariance (MI) of the scales across gender among a sample of Chinese undergraduate students. Convenience sampling was employed to recruit 1,085 subjects. Participants completed the Chinese version of the BIS/BAS scales. A confirmatory factor analysis (CFA) of competing models was conducted to determine the optimal factor model, followed by a test of MI across gender based on the optimal model. A single-group CFA indicated that the modified four-factor structure fits best in the total sample. Multiple-group CFAs demonstrated that configural invariance, weak invariance, strong invariance, and strict invariance models of the four-factor structure of the BIS/BAS scales were all acceptable. The four-factor structure of the Chinese version of the BIS/BAS scales possesses MI across gender.
识别行为抑制系统/行为激活系统（BIS/BAS）量表的最佳因素结构，并在中国本科生样本中检验该量表在性别间的测量不变性（MI）。采用便利抽样法招募了1085名受试者。参与者完成了BIS/BAS量表的中文版。对竞争模型进行验证性因素分析（CFA）以确定最佳因素模型，随后基于最佳模型对性别间的MI进行检验。单组CFA表明，修正后的四因素结构在总样本中拟合最佳。多组CFA表明，BIS/BAS量表四因素结构的构型不变性、弱不变性、强不变性和严格不变性模型均可接受。BIS/BAS量表中文版的四因素结构在性别间具有测量不变性。
