The purpose of this study was to investigate whether or not a relationship exists between levels of combat experienced by Vietnam veterans and later perceptions of violence, violent attitudes, or violent behavior. Comparison groups included: (1) heavy combat Vietnam veterans; (2) light combat Vietnam veterans; (3) no combat Vietnam veterans; and (4) civilians (non-veterans). Participants were members of central Indiana Vietnam veterans organizations. Subjects in the civilian group were friends of participants. Level of combat was determined by Figley's Level of Combat Questionnaire. Past behavioral problems and the similarity of the groups were measured by the Brief Demographic Questionnaire (BDQ). The Combat Experience Questionnaire was used to determine actual combat experiences. To gauge attitudes toward violence, the Attitudes and Issues Scale was used. The CT Scales, a modification of Straus's original Conflict Tactics Scales, were used to measure actual behavioral violence. Based upon the results of this study, levels of combat appear to be unrelated to post-war violent attitudes. Also, neither heavy nor light combat Vietnam veterans appear to engage in violent behavior any more than their Vietnam era veteran or civilian peers. (SM)
