Introduction:

Type 2 diabetes mellitus is a leading cause of morbidity and mortality worldwide, and its prevalence is even higher in middle- and low-income countries. Self-management is a strategy that has been shown to control chronic diseases.

Objective:

To determine the feasibility and preliminary efficacy of the AMAS + Vida educational intervention focused on health self-management in adults with type 2 diabetes in a primary health care facility in Neiva, Colombia.

Materials and Methods:

Feasibility study using a one-group pretest-posttest design to determine the preliminary efficacy of the intervention. Purposive sample of 36 adults with type 2 diabetes. The instruments used were a characterization form and the Partners in Health scale to measure self-management.

Results:

Thirty-one adults with diabetes completed the 3-month follow-up, most of whom were women with low socioeconomic and educational levels. The feasibility of the intervention was good. Participants significantly improved disease knowledge (p < 0.001), eating habits (p = 0.001), health self-management behaviors (p < 0.001), and decreased body mass index (p = 0.01). There were no significant changes in physical activity (p = 0.125).

Discussion:

Self-management-based interventions, structured according to the theory of adaptation to chronic illness, achieve health promoting changes in people with diabetes.

Conclusions:

The intervention showed preliminary efficacy in the study group with good feasibility. Further experimental studies are recommended.
