简要总结
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).
详细描述
The investigators will compare a combined positive psychology and motivational interviewing (PP-MI) intervention that is adapted for patients with T2D to a motivational interviewing (MI) health education intervention. The MGH Diabetes Center and MGH primary care clinics will serve as the source of subjects for the study, with patients who have a diagnosis of T2D serving as potential participants. The investigators will enroll 60 participants, who will be randomized to either an 8-week PP-MI health behavior intervention or an 8-week MI-based health education intervention.
In this project, the investigators plan to do the following:
- Examine the feasibility and acceptability of an 8-week, telephone-delivered health behavior intervention utilizing PP exercises and MI with systematic goal-setting.
- Determine whether the PP-MI intervention leads to greater increases in physical activity than the MI-based education intervention in T2D patients.
- Explore the impact of the PP-MI intervention on other psychological, behavioral, and medical outcomes, compared to the MI-based education intervention.
Participants will undergo an initial screening visit during which they will meet with study staff in person. At this visit, study eligibility will be confirmed, and eligible and willing participants will be enrolled. Following enrollment, participants will complete self-report measures, and vital signs and A1c will be measured. They then will take home and wear an accelerometer for one week, to measure baseline physical activity.
Baseline information about enrolled participants will be obtained from the patients, care providers, and the electronic medical record as required for characterization of the population. This information will include data regarding medical history (type 2 diabetes mellitus), current medical variables (conditions affecting physical activity), medications, and sociodemographic data (age, gender, race/ethnicity, living alone).

入选标准
- •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).
排除标准
- •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.
