Abstract:
Objective To provide a longitudinal evaluation tool based on the frequency of aggressive be-havior for the aggression assessment of schizophrenia patients.Methods The Life History of Aggression was translated and revised to form the Life History of Aggression-Chinese Version(LHA-CV)based on 369 patients diagnosed with schizophrenia in the Chengdu community and compulsory medical insti-tution.The reliability of LHA-CV was analyzed by means of split-half reliability,test-retest reliability and inter-evaluator consistency.The validity was analyzed by item analysis,construct validity and crite-rion validity.Results Item analysis found that LHA-CV had good homogeneity and discriminant validity.Exploratory factor analysis found that the Kaiser-Meyer-Olkin(KMO)test value was 0.80,and the Bartlett's sphericity test χ2=1203.46(P<0.05),and it revealed four factors including non-physical ag-gression,physical aggression,self-directed aggression and antisocial behavior/consequences.The factor loadings for all 11 items were greater than 0.40.Confirmatory factor analysis was performed on the factor model,Chi-square degree of freedom(χ2/df)was 3.61,root mean square error of approxima-tion(RMSEA)was 0.07,goodness-of-fit index(GFI)was 0.92,comparative fit index(CFI)was 0.90,incremental fit index(IFI)was 0.90,and the discriminant validity of each factor was good.The criterion validity test showed the total score of LHA-CV was positively correlated with the aggressive behavior level of MacArthur Community Violence Instrument,the total score of Buss-Perry Aggression Scale,and the score of Antisocial Personality Disorder Subscale of Personality Diagnostic Question-naire-4th Edition Plus(PDQ-4+_ASPD,P<0.05).The Cronbach's α coefficient of non-physical aggres-sion,physical aggression,self-directed aggression,antisocial behavior/consequences and LHA-CV total score were 0.82,0.73,0.74,0.56 and 0.79,respectively.The test-retest reliability,Spearman-Brown split-half reliability and intra-class correlation coefficient of LHA-CV total score were 0.82(P<0.05),0.66 and 0.99,respectively.Conclusion LHA-CV has good reliability and validity,and can be used as an evaluation tool for longitudinally assessing aggressive behavior in schizophrenia patients.
