行为激活抑制量表在中国军人群体中的应用分析

The revision of behavioral activation/inhibition scales in military population and the examination of psychometric properties

目的验证行为激活/抑制量表中文版在中国军人群体中的适用性，修订量表和建立因素模型。方法采用整群随机抽样方法，采用行为激活/抑制量表中文版（18题）对全国来自3个军区的2 921名军人开展调查，利用SPSS 22.0进行探索性因素分析，在固定和不固定因子数目两种情况下建立模型，在Amos 17.0中通过验证性因素分析验证模型的拟合效果。结果和Carver及White四因素模型，以及中国大学生四因素模型不同，中国军人行为激活/抑制系统符合三因素模型（行为抑制、奖赏反应性、驱力），修订后量表包括13个题项，模型拟合效果良好（KMO＝0.87，CFI＝0.94，RMSEA＝0.06），各分量表内部一致性信度Cronbach α系数分别是行为抑制0.78，驱力0.71，奖赏反应性0.67。其中行为抑制和驱力分量表内部一致性高于大学生四因素模型，驱力和奖赏反应性分量表内部一致性低于国外同年龄群体。行为抑制和驱力可以正向预测抑郁程度（βBIS＝0.332，βDrive＝0.076，P〈0.001），奖赏反应性可以反向预测抑郁程度（βRRS＝－0.140，P〈0.001）。结论中国军人行为激活/抑制量表三因素模型具有良好的信效度，可以作为中国军人趋近回避动机系统的测量工具。

ObjectiveTo examine the adaptability of Carver and White’ s behavioral activation/inhibition scales （BIS/BAS Scales） in a large sample of Chinese military-man, and to revise the instrument and validate its factor structure.MethodsA total of 2 921 Chinese military-men completed four subscales： one for the Behavioral Inhibition System, and three for the Behavioral Approach System （drive, reward responsiveness, fun seeking）. Data were analyzed using exploratory and confirmatory factor analysis.The internal consistency of the subscales and the complete scale were examined.ResultsThe findings did not support Carver and White’s 4-factor structure which was validated in a sample of Chinese college students.A 3-factor structure （behavioral inhibition, reward responsiveness, drive） in Chinese military-man were extracted and validated using confirmatory factor analysis （CFA） （KMO=0.87, CFI=0.94, RMSEA=0.06）. The Cronbach α of behavioral inhibition, drive and reward responsiveness were 0.78, 0.71 and 0.67 respectively.The internal consistencies of behavioral inhibition and drive were higher than four-factor model of Chinese college students and the internal consistencies of drive and reward responsiveness were less than American young adults.Behavioral inhibition and drive positively predicted depressive symptoms （βBIS=0.332, βDrive=0.076, P〈0.001）, and reward responsiveness negatively predicted depressive symptoms （βRRS=-0.140, P〈0.001）.ConclusionThe BIS/BAS Scales （revised Chinese military version） has acceptable reliability and validity, and can be utilized as a measurement tool for assessing the approach/avoidance motivation of Chinese servicemen.
