The purpose of this study is to examine the impacts of psychological security, emotional intelligence and self-efficacy on life satisfaction. The study was conducted among undergraduates in Nigeria where evidence of low life satisfaction has been established. Data were collected from 273 (178 males and 95 females) participants purposively selected from a southwest State in Nigeria. Results of the study showed that psychological security, β = .27, p < .05, emotional intelligence, β = .19, p < .01, and self-efficacy, β = .21, p < .01, independently predicted life satisfaction. Furthermore, the result indicated that psychological security, emotional intelligence and self-efficacy jointly predicted life satisfaction, R² = .13, F(3, 270) = 13.63, p < .01. Based on these findings, we suggest that psycho-educational interventions that would increase undergraduates’ feelings of psychological security and enhance their emotional intelligence and self-efficacy should be organized.
