Improving glycaemic control self-efficacy and glycaemic control behaviour in Chinese patients with type 2 diabetes mellitus: randomised controlled trial

Abstract

Aims and objectives: To examine the effect of a hospital-based clinic intervention on glycaemic control self-efficacy and glycaemic control behaviour of Chinese patients with type 2 diabetes mellitus (DM).

Background: Self-efficacy expectations are related to self-management of diabetes and, in conjunction with environmental support, are better predictors of behaviour than are knowledge and skills. Enhancing self-efficacy in patients with DM has been shown to have a positive effect on behavioural change and positively influence long-term glycaemic control.

Design: A randomised controlled trial study consisting of two-group pretest-post-test.

Methods: One hundred and fifty-seven patients with type 2 DM were randomly divided into two groups: (1) the experimental group (77 patients) receiving one-month hospital-based clinic intervention and (2) the control group (80 patients) receiving usual care. Data collection instruments used in this study were Diabetes Management Self-Efficacy Scale and Summary of Diabetes Self-Care Activities Measure. Outcomes were determined by changes in glycaemic control self-efficacy and glycaemic control behaviour of patients with type 2 DM.

Results: The findings revealed that the experimental group showed statistically significant improvement in glycaemic control self-efficacy and glycaemic control behaviour immediately and four months after the intervention (F = 26.888, df = 1, 155, p < 0.05 and F = 18.619, df = 1, 155, p < 0.05, respectively).

Conclusions: One-month hospital-based clinic intervention could be useful in improving glycaemic control self-efficacy and glycaemic control behaviour.

Relevance to clinical practice: Nurses can learn and use the sources of self-efficacy to enhance patients' self-efficacy on their glycaemic control in clinical care. The health education is most important in nursing care and should be considered while organising the hospital-based clinic intervention.
