Intake assessments of salivary cortisol, survey responses, and adverse childhood experiences are associated with recovery success in an abstinence-based treatment program for substance use disorders.

Background: Connecting patients to treatment for a substance use disorder (SUD) that satisfies their needs is often complicated by confounding factors. A reliable measurement of patients' underlying stress level may be helpful because it often reflects many of the same confounders as their SUD. Whereas cortisol levels reflect physiological responses to stress, patients' cortisol levels during recovery from an SUD may serve as biomarkers for stressors that result in poor treatment outcomes, including early discontinuation of treatment.
