The purpose of this study was to investigate the difference between normal control group and schizophrenic patients who committed homicidal behavior in response to frustration using P.F.T.(Picture-Frustration-test) and MMPI. The study subjects were 77 homicidal schizophrenics who were admitted to the Forensic Psychiatric Institution from October, 1989 to Febrary, 1990 and 83 normal control group who had nocrime history and psychiatric problem . The following results were obtained 1) As to the direction in P.F.T., homicidal schizophrenics responded rather in intropunitive or impunitive direction than inextrapunitive direction compared with normal control group. 2 ) As to the reaction type in P.F.T., homicidal schizophrenics showed more need-persistence (N -P ) type and less obstacle-dom inance (O -D ) type than norm al control group. 3) Regarding the superego factors in P.F.T., homicidal schizophrenics showed significantly less socore in E, I，E + E , E - E and M + I response than normal control group. 4 ) Homicidal schizophrenics exhibited significantly less G.C.R. score than normal control group, which is correlated with sociality and appropriateness for age in response to frustration. 5) In the validity scale of L,F,K and in the clinical scale of D , Pd, Pa, Pt Scon MMPI, homicidal schizophrenics remarked significantly high T score than normal control group.
