Abstract
Responses of 142 Vietnam veterans on two frequently employed measures of combat stress were factor analyzed. Four factors emerged, each of which represented an aspect of participation in activities within the Vietnam war zone. One factor in particular, abusive violence, was significantly related to postservice problems of adjustment and was the most powerful predictor of a diagnosis of combat-related posttraumatic stress disorder. Our data suggest that unidimensional models of war zone stress that focus exclusively on exposure to life threat in combat situations are inadequate for characterizing important features of the Vietnam theater that are related to subsequent psychopathology.
