Brief 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).

Study Arms (2)

Positive Psychology + Motivational Interviewing

EXPERIMENTAL

Participants will complete weekly positive psychology exercises and will systematically set goals related to physical activity. Study trainers will review the positive psychology exercises on the phone each week and will use motivational interviewing techniques to facilitate goal setting.

Behavioral: Positive Psychology + Motivational Interviewing

MI-Based Health Education Intervention

ACTIVE COMPARATOR

Participants will speak on the telephone each week with a study trainer. During these calls, the trainer will provide education about a health behavior related to diabetes health (physical activity, medication adherence, diet) and will use motivational interviewing techniques to facilitate the consideration of behavior change.

Behavioral: MI-based Health Education Intervention

Interventions

Positive Psychology + Motivational Interviewing BEHAVIORAL

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).

Positive Psychology + Motivational Interviewing

MI-based Health Education Intervention BEHAVIORAL

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.

MI-Based Health Education Intervention

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• T2D. Eligible patients will meet American Diabetes Association (ADA) criteria for T2D (e.g., HbA1c \[A1C\] ≥6.5%, fasting glucose ≥126 mg/d), with diagnosis confirmed by their diabetes clinician and/or medical record review.
• Low physical activity. Low physical activity will be defined as ≤150 minutes/week of MVPA (corresponding to ADA recommendations for moderate or greater intensity aerobic physical activity). Physical activity will be measured using a brief questionnaire adapted from the International Physical Activity Questionnaire (IPAQ).

You may not qualify if:

• Cognitive impairment precluding consent or meaningful participation.
• Lack of phone availability.
• Inability to read/write in English.
• Additional medical conditions (e.g., severe arthritis) that preclude physical activity.
• Enrollment in mind-body programs, lifestyle intervention programs (e.g., cardiac rehabilitation), or other clinical trials.
