Timeline
Interventions
Participants randomized to PP-MI will receive a treatment manual. For each session, a PP exercise will be described in the manual, with instructions and space to write about the exercise and its effects. Next, an MI section will outline specific MI-based topics (e.g., pros/cons, managing slips) and facilitate physical activity goal-setting. Following randomization, participants will engage in weekly, 30-minute phone calls over the next 16 weeks. Participants will independently complete PP exercises and MI-based goals between phone sessions and review them during phone sessions. PP and MI components will be delivered stepwise within sessions (rather than intertwined).
Each week, participants will learn about a different health behavior topic related to diabetes health. As an attentional control, this condition has a parallel structure to the experimental arm with a treatment manual, weekly assignments, and weekly calls to review assignments.
