Summary

The focus of this study is to examine the feasibility, acceptability, and impact of a customized, combined positive psychology and motivational interviewing (PP-MI) health behavior intervention versus a motivational interviewing (MI) health education intervention in a group of patients with type 2 diabetes (T2D).

Conditions

  • Type2 Diabetes

Interventions

BEHAVIORAL

Positive Psychology + Motivational Interviewing

Participants randomized to PP-MI will receive a treatment manual. For each session, a PP exercise will be described in the manual, with instruments 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 8 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 step-wise within sessions (rather than intertwined).

BEHAVIORAL

MI-based Health Education Intervention

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. Motivational interviewing topics (e.g., pros and cons of behavior change, importance and confidence of behavior change, identification of barriers and resources to change) will be presented related to each health behavior.
