Medical Nutrition Therapy, In-Person, or Telephone Group Lifestyle Intervention for Type 2 Diabetes? A Qualitative Study of Patient Perceptions and Treatment Preferences.

Abstract

The purpose of the study was to explore the thoughts, feelings, motivations, and assignment preferences of community health center patients with type 2 diabetes considering participation in a 2-year lifestyle intervention trial aimed at weight loss and increased physical activity. The reasons for patients' delivery mode preferences were also explored to aid in the design of future interventions for controlled trials. Using structured telephone interview guides, 57 patients with type 2 diabetes receiving primary care at 3 community health centers affiliated with an academic medical center were interviewed regarding the perceived pros and cons of each of the 3 possible treatment assignments: telephone conference group, in-person group, or individual medical nutrition therapy. The interview data were organized using NVIVO and analyzed using content analysis. Findings on whether preferences varied by age, gender, or diabetes duration were also examined. Six categories related to patient treatment preferences were identified: (1) perception of time, (2) learning style, (3) comfort, (4) prior experience with weight loss programs and conference calls, (5) desire for support/idea exchange, and (6) accountability. Preferences did not seem to vary by age, gender, or diabetes duration. Key factors influencing preference of treatment assignment included schedule demands, belief about learning style, and past experiences. These findings demonstrate the importance of having a variety of nutrition and lifestyle treatment options available to meet the needs of people with type 2 diabetes.
