A stress-coping profile of opioid dependent individuals entering naltrexone treatment: a comparison with healthy controls.

Background: Stress is known to increase addiction vulnerability and risk of relapse to substance use. PURPOSE & METHOD: We compared opioid dependent individuals entering naltrexone treatment (n = 57) with healthy controls (n = 75) on measures of stress, coping, and social support and examined the relative contribution of group membership, coping, and social support to stress within the sample. Analyses of variance (ANOVA) and covariance (ANCOVA), and stepwise multiple regression were conducted.
