RecruitingClinical trialDevelopment of Pain Management JITAI Content in Multiple Sclerosis and Spinal Cord InjuryJust-In-Time Adaptive Interventions (JITAIs) offer a framework for delivering personalized behavioral support using time-varying data to optimize the timing and type of intervention content. This project will develop the foundational components of a JITAI tailored to adults with chronic pain and either MS or SCI by drawing on symptom self-management content from existing programs (PainGuide, MyMSToolkit, and MySCIToolkit). Intervention content and delivery parameters will be refined through stakeholder engagement via structured interviews to ensure relevance, acceptability, and feasibility.
