Efficacy of a Brief Self-management Intervention in Type 2 Diabetes Mellitus: A Randomized Controlled Trial from India

Abstract

Background: Diabetes mellitus places a considerable burden on the individual and the family with respect to lifestyle changes. There is a paucity of systematic studies in India examining the efficacy of self-management programs for diabetes. The study examined the impact of a brief self-management intervention (SMI) on primary outcome of HbA1c and secondary outcomes of quality of life (QOL), self-care, perceived barriers to self-care (BSC), perceptions regarding illness and mood in patients with type 2 diabetes mellitus. Methods and materials: Eighty patients with type 2 diabetes mellitus were randomly allocated to either a 4-session SMI or treatment as usual (TAU) and were assessed on HbA1c levels, QOL, self-care, BSC, illness perceptions, anxiety, and depression at baseline, postintervention, and at three-month postintervention follow-up. Results: Repeated measures analysis of variance indicated significant improvement in the SMI group from baseline to follow-up on HbA1c (P = 0.001), impact of diabetes on QOL (P = 0.006), self-care with respect to diet and exercise (Ps = 0.001), perceived barriers in adherence to diet, exercise, (P = 0.001), medication (P < 0.01), glucose testing (P = 0.04), general BSC (P = 0.001), total barriers (P = 0.001), illness perceptions-timeline or chronicity of illness (P = 0.002), personal control over illness, (P = 0.001), belief in effectiveness of treatment (P = 0.002), understanding of one’s illness (P = 0.001), and emotional representations regarding illness (P =0.001), depression, (P = 0.001), and anxiety (P = 0.001). In the SMI group, large effect sizes were obtained at the postintervention assessment and the three-month follow-up on most outcome measures. Conclusions: Brief psychological intervention is efficacious in patients with type 2 diabetes.
