Health Action Process Approach in Non-Communicable Diseases: A Systematic Review

Background: Epidemiological research has indicated that the deleterious effects of non-communicable disease can be prevented through participation in health behaviours. The HAPA is a dual-phase model that identifies the determinants of the initiation and maintenance of health behaviour. The aim of this study was to systematically map the Health Action Process Approach (HAPA)- based interventions in non-communicable diseases in relation to the type of intervention, the target groups and the constructs of the HAPA model that are used in the study and to assess the clinical relevance of the studies. Methods: This review study complies with the Preferred Reporting Items for Systematic review and Meta-analysis (PRISMA) version 2020. The search for relevant literature involved PubMed, Sciencedirect, Willey online Library and Proquest databases for the studies published in 2000 to 2023 period. Quality of the study was assessed using CASP, and the Risk of Bias using Cochrane RoB tool. Results: In databases search, there are 912 studies. The results for eligibility resulted in 18 articles consist of 13 observational studies, and 5 experimental studies. Discussion: Physical activity, healthy diet behaviour, and medication adherence were the targeted behaviour. In the majority of the studies, the targeted intervention was physical activity and the population consisted of adult patients. Conclusion: All studies used only a selection of the HAPA constructs. Therefore, only a minority of the studies can be considered real HAPA intervention studies.
