Effects of motivational enhancement therapy plus cognitive behaviour therapy on depressive symptoms and health-related quality of life in adults with type II diabetes mellitus: a randomised controlled trial.

<bold>Objective: </bold>This paper evaluates the effectiveness of motivational enhancement therapy plus cognitive behavioural therapy on depressive symptoms, glycosylated haemoglobin, fasting glucose, body mass index (BMI), and health-related quality of life in type II diabetes patients.<bold>Methods: </bold>A controlled trial was conducted to compare patients who received the behavioural intervention with untreated controls on measures of health outcomes. A total of 31 intervention group participants and 30 controls were selected from patients that met the inclusion criteria from a hospital-based endocrinology outpatient department. The outcome measures including depressive symptoms, glycosylated haemoglobin, fasting glucose, BMI, and both physical and mental quality of life were collected before (T1), after (T2), and after 90 days (T3) following the intervention.<bold>Results: </bold>The experimental group showed a significant reduction in glycosylated haemoglobin, fasting glucose, and depressive symptoms and a significant increase in physical quality of life and mental quality of life at T2 and T3, while patients in the control group with usual care showed no changes over time.<bold>Conclusion: </bold>The behavioural intervention facilitated a significant improvement in psychological adjustment and glycemic control, thus strengthening diabetes control skills and leading to healthy outcomes. It is feasible that nurses and psychiatrists can deliver the behavioural intervention for diabetes patients to decrease their depressive symptoms. Sharing discussion and problem-solving experiences is particularly helpful method for self-control, and these will be beneficially influential on further research. [ABSTRACT FROM AUTHOR]
