The Patient Activation Measure (PAM) evaluates patients' confidence, skills, and knowledge in managing their health. Higher activation levels are linked to better health behaviors and outcomes, as well as reduced healthcare use. However, there is limited information on PAM's application during care transitions, especially among socioeconomically disadvantaged adults. This study analyzes data from the Care Transitions Innovation study, a transitional care intervention for uninsured and low-income publicly insured adults.
