BACKGROUND Substance use disorder (SUD) resolution typically involves a long-term, comprehensive process of change now widely referred to as "recovery." Yet, definitions of recovery vary substantially, producing significant confusion. To support formal recovery definitions, we aimed to systematically identify recovery elements that are central to those in recovery and shared regardless of subgroup/pathway.

METHODS Data were from the What is Recovery? Study, involving a diverse, national, online survey of people in recovery (N = 9341). Surveys included a 35-item recovery measure reflecting 4 domains; participants reported whether or not each element definitely belonged in their recovery definitions. Analyses examined item endorsements overall and among 30 subgroups defined (by sociodemographics, substance use characteristics, and help-seeking history) to determine where items met study-specific centrality thresholds (ie, endorsement by ⩾80% and top-10 ranking, by endorsement level). We then classified items as "core" if meeting centrality thresholds both overall and for all 30 subgroups, and "prevalent" if meeting centrality thresholds overall and for 26 to 29 subgroups.

RESULTS Four "core" recovery elements emerged, including a process of growth or development; being honest with oneself; taking responsibility for the things one can change; and reacting in a more balanced way. Four "prevalent" recovery elements also emerged, referencing the ability to enjoy life and handle negative feelings without substance use; abstinence and/or nonproblematic substance use; and living a life that contributes. Subgroups differing most in their endorsements included those reporting mild/moderate SUD severity; non-abstinent recovery; and no specialty treatment or mutual-help group attendance.

CONCLUSIONS Recovery elements identified here partially reflect some stakeholder definitions, but offer greater specificity and include novel elements (eg, personal integrity). Elements may point to areas of functioning that are damaged in the addiction process and can support an addiction-free life. Findings should inform institutional recovery definitions; SUD services and research; and communications about recovery.
