Background The prevalence of metabolic syndrome among office workers is markedly high, highlighting an urgent need for effective workplace interventions. In response to this need, a theory-informed healthy lifestyle education intervention was developed and implemented among office workers in Ethiopia, resulting in significant reductions in key metabolic risk factors and improvements in health-related behaviours. However, understanding the implementation process, how the intervention worked in practice, under what conditions, and why is critical to inform scale-up, adaptation, and sustainability. This study aimed to evaluate the implementation process of a nine-month workplace-based healthy lifestyle education intervention, using the Programme Integrity Framework to assess implementation fidelity and the Consolidated Framework for Implementation Research to identify the barriers and facilitators influencing implementation. Methods A convergent parallel mixed-methods process evaluation was conducted to assess the implementation process of a 9 month workplace intervention aimed to reduce risk for metabolic syndrome and improve knowledge, attitudes, and healthy lifestyle practices. A total of 226 employees were screened based on waist circumference and blood pressure and allocated to intervention and control groups using cluster randomisation. The intervention group received a personalised lifestyle education programme delivered by trained health promotion experts, while the control group received general health advice on non-communicable disease prevention. Implementation fidelity was assessed across the five domains of the Programme Integrity Framework: adherence, exposure, quality of delivery, participant responsiveness, and programme differentiation, using educator self-reports and direct observations conducted by the principal investigator. Contextual factors influencing implementation were examined using the five domains of the Consolidated Framework for Implementation Research (CFIR): intervention characteristics, outer setting, inner setting, characteristics of individuals, and process. These were assessed through participant self-reports, field notes from review meetings conducted at the third and sixth months, and open-ended questionnaire responses collected from 13 participants. Results Implementation fidelity was high across adherence, exposure, quality of delivery, and participant responsiveness domains, indicating that the intervention was delivered as intended and well-received by participants. However, CFIR-informed contextual analysis identified several barriers to effective implementation, including unsupportive organisational cultures, limited leadership support, weak external policy backing, resource constraints, and community norms that were not always aligned with healthy lifestyle change. Conclusion This study shows that a theory-informed lifestyle education intervention can be delivered with high fidelity and strong engagement among office workers, supporting workplaces as a promising NCD prevention setting. Sustainable scale-up will likely depend on task-sharing with trained non-specialist personnel and embedding workplace health promotion within organisational and policy systems. Future research should work on policy integration, scalability, long-term sustainability, equity, and cost-effectiveness.

Study methods

This process evaluation study, rooted within a broader implementation research project, used a convergent parallel mixed-methods design. Quantitative and qualitative data were collected during the same implementation period, analysed separately, and then integrated at the interpretation stage. Intervention fidelity and contextual determinants influencing implementation of the workplace healthy lifestyle education intervention were assessed. The intervention was designed and implemented to reduce MetS risk factors and to examine changes in participants’ knowledge and attitudes related to MetS, CVDs and associated risk factors, as well as healthy lifestyle behaviours. The effectiveness of the intervention was evaluated using a cluster-randomised controlled trial (RCT) design among Bahir Dar City bank employees (19). Because Bahir Dar City is divided into two geographical clusters by the Abay River, banks in one area were allocated to the intervention arm and those in the other area to the control arm. Due to the nature of the intervention, participants could not be blinded to group allocation, but they were unaware of their assigned arm, while data collectors, laboratory personnel, and the intervention provider remained blinded.

Limitations

A key strength of this study is its comprehensive evaluation of intervention fidelity and implementation using both the PIF and CFIR, enabling systematic examination of multilevel facilitators and barriers within a real-world LMIC workplace setting. The use of mixed methods and a joint display further strengthened analytic integration, allowing quantitative fidelity scores to be interpreted alongside contextual and organisational influences. However, several limitations should be acknowledged.

A 90-day district inquiry

Days 1–15 · Appraise. Read the source methods, recruitment, comparator, outcomes and limitations. Record how the study setting differs from your district and which claim the design can support.
Days 16–30 · Design. Choose one school improvement question with teachers. Protect a short shared planning cycle, agree an instructional change and use a common rubric for examining student work. Agree participation, privacy protections, baseline and stopping rules before starting.
Days 31–60 · Observe. Collect the pre-agreed measures, keep a log of implementation changes and invite confidential voluntary feedback. Preserve existing support for staff and learners.
Days 61–90 · Decide. Review implementation fidelity, teacher time and independently scored student work against a recorded baseline. Examine access differences and competing explanations before attributing changes to leadership. Make a dated decision to stop, revise or extend the inquiry.
