Objectives: The aim of this systematic review was to identify factors influencing workers' intention to work while ill, using the Theory of Planned Behavior (TPB) as a theoretical framework.
Methods: A systematic search of articles was carried out from PubMed, Scopus, and Web of Science databases. Eligibility of each article was assessed using PRISMA guidelines. Overall, 22 articles met the inclusion criteria after the selection process and were included in this review.
Results: The factors fit into 3 constructs: (1) attitude (good and bad consequences of working while ill), (2) subjective norms (descriptive and injunctive norms on working while ill), and (3) perceived behavioral control (facilitators and barriers of working while ill).
Conclusions: The TPB is a practical theory to conceptualize and understand the factors influencing workers' intention to work while ill. These findings provide initial knowledge on the development of a framework to measure workers' intention to work while ill and to propose appropriate interventions for workers with chronic illness.
