Modified realist evaluation of a complex, multi-centred, multi-intervention programme.

Area of Science:

• Public Health
• Health Services Research
• Socioeconomic Determinants of Health

Background:

• The Well North program was a large-scale, multi-site initiative in Northern England aimed at reducing health inequalities.
• It focused on improving the health of disadvantaged populations, enhancing resilience, and decreasing worklessness.
• Local sites had autonomy to implement tailored interventions based on community needs.

Purpose of the Study:

• To evaluate the complex Well North health improvement program.
• To understand what works, for whom, and in what circumstances, by adapting realist methodology.
• To provide iterative feedback for program adaptation and improvement.

Main Methods:

• A modified realist evaluation framework was employed.
• Qualitative and quantitative methods were integrated within a Rapid Cycle Evaluation.
• Contexts, Mechanisms, and Outcomes (CMOs) were identified and theorized iteratively.

Main Results:

• The study identified key Contexts, Mechanisms, and Outcomes (CMOs) configurations for various interventions.
• A middle-range theory was developed and refined through continuous validation.
• Adaptations to the realist methodology were necessary to accommodate program complexity.

Conclusions:

• Realist methodology, though requiring modification, proved effective for evaluating complex health programs.
• The iterative approach facilitated program learning and adaptation.
• The evaluation provided valuable insights into addressing health inequalities through targeted interventions.
