Methods Indicators such as dem ographic and clinical data, characteristics of crim inal behaviors and crim inal capacity from the suspects w hom w ere diagnosed by forensic psychiatry as schizophrenia (n=110) and norm al m ental (n=70) w ith hom icide behavior, w ere collected by self-m ade investigation form and com pared. T he influences of the assessm ents of crim inal capacity on the suspects diagnosed as schizophrenia w ere also analyzed using logistic regression analysis. Results T here w ere no significant statistical differences betw een the schizophrenic group and the norm al m ental group concerning age, gender, education and m arital status (P>0.05). T here w ere significant sta-tistical differences betw een the tw o groups concerning thought disorder, em otion state and social function before crim e (P<0.05) and there w ere significant statistical differences in som e characteristics of the case such as aggressive history (P<0.05), cue, trigger, plan, crim inal incentives, object of crim e, circum stance cognition and self-protection ( P<0 .05 ) . M ultivariate logistic regression analysis suggested that thought disorder, em otion state, social function, crim inal incentives, plan and self-protection before crim e of the schizophrenic group w ere positively correlated w ith the crim inal capacity (P<0.05). Conclusion T he rele-vant influences of psychopathology and crim e characteristics should be considered com prehensively for im proving the accuracy of the crim inal capacity evaluation on the suspects diagnosed as schizophrenia w ith hom icide behavior.
