The emotional well-being of a group of incarcerated Vietnam veterans within the maximum security section of a state prison was assessed along with comparison groups of veterans and nonveterans. The Multiple Affect Adjective Check List (MAACL) (Zuckerman & Lubin, 1965), the Adjective Check List (ACL) (Gough & Heilbrun, 1983), and the Military Life Questionnaire (MLQ) (Panzarella, Mantell, & Bridenbaugh, 1978) were administered. Both the factors of incarceration and Vietnam experience proved significant on a number of MAACL, ACL, and MLQ measures, including depression, anxiety, hostility, and personal adjustment. The MLQ results also indicated that, compared to their nonincarcerated counterparts, the incarcerated veterans were more likely to be black, to have come from a less supportive family background, to have been assigned to an Army infantry combat unit, to have been injured in combat, and to have witnessed or been involved in the killing of enemy soldiers, prisoners, and civilians while in Vietnam. Many incarcerated veterans apparently began as poor prospects in terms of their social, economic, and interpersonal well-being. They went to Vietnam, bore the brunt of these experiences, and emerged as even poorer prospects, all the more at risk and prone to incarceration.
