Abstract

This study examined job involvement, self-efficacy, employee optimism, and emotional intelligence as predictors of organizational citizenship behavior (OCB) among officers of the Nigeria Security and Civil Defence Corps (NSCDC) in Ibadan, Oyo State. Previous research has established links between these variables and OCB, but there is a dearth of studies specifically focused on security personnel in this region. The study utilized a cross-sectional survey design with 379 NSCDC officers (220 males, 159 females) as participants. Data was collected via self-report measures of job involvement, self-efficacy, optimism, emotional intelligence, and OCB. Multiple regression analysis revealed that job involvement, optimism, and emotional intelligence significantly and positively predicted OCB, while self-efficacy was not a significant predictor. No gender or marital status differences in OCB were found. The findings highlight the importance of fostering job attitudes like involvement and optimism, as well as developing emotional competencies, to promote citizenship behaviors that enhance organizational effectiveness among security personnel. Recommendations for practice and future research directions are discussed.
