The present research was designed to address the gap in research regarding recovery capital, stress, and drug-taking abstinence self-efficacy. Prior research on recovery capital and stress has demonstrated that recovery capital buffers stress in recovery and enhances quality of life. Additionally, prior research has demonstrated that stress depletes self-control, and contributes to continued relapse behaviors, while self-efficacy represents the ability to abstain from drug use. The current research sought to examine the role of recovery capital as a mediator between stress and drug-taking abstinence self-efficacy. Participants in the community completed a survey packet that measure recovery capital, perceived stress, and drug-taking abstinence self-efficacy, as well as additional demographic and psychosocial background information. Results indicated that recovery capital mediated the relationship between stress and drug-taking self-efficacy. Additionally, results indicated significant relationships between the demographics, independent and dependent variables.
