Abstract:
Objective The purpose of the present study was to examine the reliability and validity of the Chinese version of the impulsive-premeditated aggression scale (IPAS) in a sample of Chinese adolescents with aggression. Methods 126 adolescents completed the IPAS,Barratt impulsive scale and self-report questionnaires. In order to assess test-retest reliability, the IPAS was re-administered to 30 participants 3 weeks later.Results Item analysis showed that IPAS had satisfactory item discrimination, 6 items were excluded in the later analysis. The internal consistency of the IPAS Cronbach alpha was 0.77 and the test-retest reliability was 0.74.Exploratory factor analysis demonstrated two stable factors of aggression with good internal consistency and construct validity, the value of KMO was 0.646, the χ2 value of Bartlett test was 691.93 ( P <0.001). The confirmatory factor analysis showed that the value of χ2/df,GFI,AGFI,RMSEA were 1.42,0.874,0.837 and 0.058 respectively.The whole scale and the two secondly scales all correlated with BIS-11 and MOAS.Conclusion The results of the current study indicate that the Chinese version of the IPAS is a useful tool to subtyping aggressive behavior among adolescents, but it still need to be modified to apply in China.
