A positive psychology-motivational interviewing intervention for patients with type 2 diabetes: Proof-of-concept trial.

ABSTRACT: OBJECTIVE:Eighteen million Americans with type 2 diabetes (T2D) do not follow recommended guidelines for physical activity. Motivational interviewing (MI) has had modest effects on activity and related behaviors in T2D. Positive psychological attributes (e.g., optimism) are associated with superior medical outcomes in T2D, and positive psychology (PP) interventions promote such attributes. There had been no study in T2D of a combined PP-MI intervention to promote well-being and health behavior adherence. We developed a novel, telephone-delivered, 16-week PP-MI intervention and explored its feasibility and impact in T2D patients in a single-arm, proof-of-concept trial. METHOD:Participants completed PP-based exercises and MI-based physical activity goal-setting activities and reviewed these activities weekly with a study trainer for 16 weeks. Feasibility and acceptability were assessed via exercise completion rates and post-exercise ratings of ease/utility (0-10 scales). Impact was explored by examining changes in physical activity (via accelerometers and self-report), other health behaviors, psychological measures, and medical outcomes (e.g., hemoglobin A1c (A1C)) from baseline to 16 weeks, using paired t tests. RESULTS:Twelve participants enrolled, and 10 provided follow-up data. Seventy-eight percent of PP-MI activities were completed, and participants rated the PP-MI content and sessions as easy (mean?=?8.2/10, standard deviation (SD)?=?1.9) and useful (mean?=?9.1/10, SD?=?1.5). PP-MI was associated with improved adherence to health behaviors and overall self-care, variable effects on accelerometer-measured activity and psychological outcomes, and modest beneficial effects on body mass index and A1C. CONCLUSION:Further testing of this intervention is warranted in a larger, controlled trial to assess its effects on important health outcomes.

Project description:BackgroundPhysical activity is critical for preventing and treating Type 2 diabetes (T2D). It is important to identify different profiles of physical activity change among those participating in behavioral interventions to optimize intervention-person fit.MethodsThis study analyzes longitudinal trajectories of change in moderate-to-vigorous physical activity (MVPA) in a positive psychology (PP) and motivational interviewing (MI) intervention for T2D, using latent growth curve modeling (LGCM). Objective measures of MVPA were collected using accelerometers at three time points: pre-intervention, immediately post-intervention, and eight weeks post-intervention. LGCM analyses identified subpopulations of participants who responded similarly to the intervention and examined if sociodemographic, medical and psychosocial characteristics were associated with MVPA trajectories.ResultsAnalyses included 47 participants with complete follow-ups: 49% male, 81% non-Hispanic white, average age 66.1 (SD = 10.1). Overall, 36% of the participants increased MVPA while 57% did not. LGCM identified three profiles with distinct MVPA trajectories. Profile 1 ('Started Low, No Change'; 65.8% of participants) with a starting mean of 4.54 min of MVPA/day and decreased by -3.36 min. Profile 2 ('Moderate-High Start, Minimal Change,' 27.4% of participants) and had a starting mean of 22.86 min/day of MVPA with an average increase of 1.03 min. Profile 3 ('Moderate Start, Ended High'; 6.8% of participants), had a starting mean of 7.33 min MVPA/day, and increased by 28.4 min. Being male, younger, having fewer medical and psychiatric comorbidities were associated with increases in MVPA.ConclusionsThis secondary analysis detected three distinct physical activity profiles during and after a PP-MI intervention. Future interventions can target individuals with characteristics that showed the greatest benefit and add additional supports to people in groups that did not increase physical activity as much. These findings show a need for targeted and sustained behavior change strategies during and after physical activity interventions. Trial registration: ClinicalTrials.gov; identifier: NCT03001999.

Project description:BackgroundPhysical activity among those with type 2 diabetes (T2D) is independently associated with superior medical outcomes, but existing behavioral interventions have not led to widespread increases in activity in this population. A remotely delivered intervention that targets well-being constructs associated with greater activity and assists in the creation of specific physical activity goals has the potential to improve activity and outcomes in T2D.ObjectiveTo outline the rationale and methods of two studies designed to assess the impact and optimal duration of a combined positive psychology-motivational interviewing (PP-MI) intervention for inactive persons with T2D.MethodsWe conducted trials studying 8-week (BEHOLD-8;) and 16-week (BEHOLD-16;) phone-delivered interventions, compared to attention-matched control conditions. In a two-step randomization design, participants were allocated randomly first to study (BEHOLD-8 or BEHOLD-16), then to study condition within study. The primary aims in both trials were feasibility (rates of session completion) and acceptability (participant session ratings), with additional aims examining intervention effects on accelerometer-measured physical activity, psychological measures, and health-related metrics (e.g. vital signs). Main analyses, currently being conducted, will utilize mixed effects models between study conditions, and secondary analyses will utilize the same models to compare the 8- and 16-week PP-MI interventions on feasibility and impact.ResultsEnrollment and data collection have been completed for both trials (BEHOLD-8: N = 60; BEHOLD-16: N = 70), and data analysis is ongoing to assess feasibility and acceptability within study, as well as the relative feasibility and acceptability of the PP-MI interventions across the two studies. We will also explore impact on clinical outcomes between groups.ConclusionsThis design will address how intervention content (i.e. PP elements vs. no PP elements) and intervention duration (8 weeks vs. 16 weeks) affect feasibility, acceptability, and impact, allowing intervention optimization before a next-step larger clinical trial.Trial registrationClinicalTrials.gov identifier: NCT03150199; NCT03001999.
