Project Summary Individuals with opioid use disorder (OUD) face both short-term and long-term challenges to healthy and productive decision-making. While recovery success is deeply affected by phasic/psychological propensity for re-use, current strategies for cravings control suffer from limited usability and restricted utility. The proposed innovation (“BoostONE”) comprises a proprietary software-delivered method for just-in-time management of such risk events, as a supplement to standard medication assisted treatment for OUD. Aims include platform refinement and a real-world feasibility study. We anticipate this Phase I SBIR will provide the foundation for deployment of BoostONE in active treatment settings and for broader extensions of the underlying novel technology framework.
