The revision of behavioral activation/inhibition scales in military population and the examination of psychometric properties / 中华行为医学与脑科学杂志

ABSTRACT

Objective To examine the adaptability of Carver and White' s behavioral activation/in-hibition scales(BIS/BAS Scales)in a large sample of Chinese military-man,and to revise the instrument and validate its factor structure. Methods A total of 2 921 Chinese military-men completed four subscalesone for the Behavioral Inhibition System,and three for the Behavioral Approach System(drive,reward re-sponsiveness,fun seeking).Data were analyzed using exploratory and confirmatory factor analysis.The internal consistency of the subscales and the complete scale were examined. Results The 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.Be-havioral 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). Conclusion The BIS/BAS Scales(revised Chinese military version)has acceptable reliability and validi-ty,and can be utilized as a measurement tool for assessing the approach/avoidance motivation of Chinese ser-vicemen.
