Methods: Multiple databases (MEDLINE, EMBASE, CINAHL, PsycINFO, and CENTRAL) were searched for studies that applied psychological frameworks of behavior change to improve and/or predict influenza vaccination uptake among HCW. Two reviewers independently conducted all steps in study selection, data extraction, and assessment of study quality and risk of bias.
Results: The literature search yielded a total of 1810 publications; 10 articles met eligibility criteria. All studies used behavior change frameworks to predict HCW vaccination behavior; none evaluated interventions based on these frameworks. The Health Belief Model was the most frequently employed framework (60% of studies) to predict influenza vaccination uptake among HCW. The behavior change framework constructs were successful in differentiating between vaccinated and non-vaccinated HCW (p<.05). Key constructs identified included: attitudes regarding the efficacy and safety of influenza vaccination, perceptions of risk and benefit to self and others, self-efficacy, cues to action, and social-professional norms. The behavior change frameworks, along with sociodemographic variables, successfully predicted 89% to 95% of HCW influenza vaccination uptake.
Conclusion: Vaccination is a complex behavior. Our results suggest that psychological frameworks of behavior change are promising tools to increase HCW influenza vaccination uptake. Future studies are needed to develop and evaluate novel interventions based on behavior change frameworks, which may help achieve recommended HCW vaccination targets.
