目的:验证BIS-11在不同青少年群体中的信度和六种因素模型的结构效度。方法:分别在正常青少年(n=406)、精神障碍青少年(n=258)、违法青少年(n=331)三组样本中进行信度分析;采用验证性因素分析在总样本及三组青少年样本中验证6种因素结构模型。结果:三组青少年样本BIS-11总量表及三个分量表(运动冲动性、认知冲动性、非计划性)内部一致性Crobach’sα在0.67-0.89之间,三组样本之间量表得分差异有统计学意义(P<0.05),正常青少年的冲动性得分(76.10±15.81)最低,精神障碍青少年(83.28±18.01)次之,违法青少年(86.05±15.77)最高。验证性因素分析结果支持三因子相关模型、六因子相关模型和双因素模型(G-3模型、G-6模型),其中三因素模型和G-3模型模型拟合最为理想。结论:中文版BIS-11在不同青少年群体中具有较好的信度和结构效度,适应于青少年冲动性人格特质的测评与解释。
Aims: To verify the reliability of BIS-11 in different adolescents and the structural validity of the six-factor model. Methods: The reliability analysis was carried out in three groups of normal adolescents (n = 406), mentally disabled adolescents (n = 258) and illegal adolescents (n = 331) respectively. In the verification of six kinds of factors in the structural model. Results: The Crobach’s α was between 0.67 and 0.89 in the BIS-11 total scale and the three sub-scales (exercise impulse, cognitive impulses and unplannedness) in three groups of young people. There was significant difference between the two groups (P <0.05). The score of impulsivity (76.10 ± 15.81) in normal adolescents was the lowest. The number of adolescents with mental disorders (83.28 ± 18.01) and the number of infants (86.05 ± 15.77) were the highest. The results of confirmatory factor analysis supported the three-factor correlation model, the six-factor correlation model and the two-factor model (G-3 model and G-6 model). The three-factor model and the G- Conclusion: The Chinese version of BIS-11 has good reliability and structural validity in different adolescents and is suitable for the assessment and explanation of adolescent impulsive personality traits.
