Behavior change, health, and health disparities 2023: Contingency management for treating substance use disorders and promoting health in vulnerable populations.

This Special Issue (SI) of Preventive Medicine is the 10th in a series on behavior change, health, and health disparities. This issue focuses on Contingency Management (CM), a highly efficacious behavior-change intervention for substance use disorders (SUDs) and other behavioral health conditions wherein patients receive material incentives (e.g., vouchers exchangeable for retail items) contingent on objectively verified behavior change. Despite substantial support for its efficacy, CM remains largely unavailable in U.S. community SUD treatment facilities and other healthcare settings. This is especially concerning regarding stimulant use disorder for which CM is the only reliably efficacious intervention in controlled studies and yet is unavailable to the vast majority of those in need. This SI details recent promising developments in efforts to surmount longstanding implementation obstacles while also detailing other promising advances from meta-analyses and controlled trials examining CM's efficacy in treating other difficult-to-treat problems including smoking among pregnant women and mothers of young children as well among those as those experiencing homelessness and alcohol use disorder, the promise of digital CM, and a potential new application in promoting adherence with SUD medications.
