The Interaction Effect of Psychological Capital on the relationship between Self-Driven Personality and Happiness at Work.https://nru.uncst.go.ug/handle/123456789/6789The purpose of this paper is to examine how Psychological Capital and Self-Driven Personality fuse to affect Happiness at Work in the nursing profession in Uganda. The paper adopts a cross-sectional descriptive and analytical design. The authors employ structural equation modeling to test hypotheses. Using proportionate and simple random sampling procedures, a sample of 900 respondents was drawn from different hospitals in Uganda of which a response rate of 88.8 percent was obtained. The magnitude effect of Self-Driven Personality on Happiness at Work depends on Psychological Capital; implying that the assumption of non-additivity is met. Only a single research methodological approach was employed and future research through interviews could be undertaken to triangulate. In order to boost happiness at the workplace, heads of hospitals should always endeavor to find a viable self-driven personality- psychological capital blend that can add value to nurses in Uganda. This is one of the few studies that focus on testing the interactive effects of psychological capital on the relationship between self-driven personality and happiness at the workplace in Uganda’s health sector.enInteraction EffectHappiness at the WorkplacePsychological CapitalSelf-Driven PersonalityNursingArticle
