Introduction

Type 2 diabetes mellitus (T2DM) is a lifelong condition that has large societal, economic and clinical implications, and treatment should be supported by healthy lifestyle factors. Interventions for effective self-management are essential to the sustainability of treatment, however there is no standard approach.

Research Design and Methods

Six hundred and five participants diagnosed with Type 2 Diabetes Mellitus were recruited from four countries (UK, France, Netherlands, Belgium) to complete the 12-week DWELL (Diabetes and WELLbeing) psychoeducational intervention. The programme was delivered at community and hospital-based settings and comprised of four key areas: education, nutrition, physical activity and wellbeing. Metabolic health (weight, waist size, BMI and HbA1c) and self-reported psychological measures were taken at four points: pre- and post-intervention, and two follow up points (at 6 and 12 months) to assess the impact of the programme.

Results

Participants showed a significant reduction in all metabolic health measures, with improvements in both weight and BMI being maintained at 6-month follow-up. Participation in the programme also led to enhanced levels of participant empowerment, with significant improvements also seen in perceptions of diabetes, eating behaviours, mental and physical health, and self-care behaviours.

Conclusions

The study results demonstrated that an empowerment-based, holistic and flexible approach to diabetes self-management education programmes has a wider impact in improving longer term coping behaviours which help in achieving and sustaining positive metabolic and psychological changes.

Key Messages

What is already known on this topic

Diabetes education has evolved from a compliance and knowledge-oriented approach to an empowerment and self-management-oriented approach. Yet, type 2 diabetes self-management education (DSME) programmes are mainly evaluated in relation to impact on metabolic (glycaemic) outcomes than on wider psychosocial outcomes.

What this study adds

Participation in the DWELL programme led to significant improvements in metabolic health measures and produced significant positive changes across a range of psychological measures such as patient empowerment, illness perceptions, eating behaviours and self-care behaviours.

How this study might affect research, practice or policy

The DWELL DSME programme which was co-designed with patients, healthcare professionals and family carers, focussed on patient empowerment and self-control, by offering flexibility and choice of options as well as peer support. Programme outcomes indicated that this approach led to positive changes in empowering and enabling health behaviour changes and improvements in metabolic health. The study adds to the body of knowledge of patient-led DSME practice with a holistic approach. Further research could shed light on the cultural and intersectional aspects of such approach that can inform more targeted programmes supporting T2DM patients with multiple co-morbidities such as serious mental health conditions.
