Satisfied correctional officers are important for the successful operation of a prison. Hierarchical multiple regression analysis (HMR) was performed on survey data from 501 non-supervisory correctional officers employed in a Southern prison system. After controlling for factors such as demographic variables, role conflict, job stress, peer support, and supervisory support, correctional officers who perceived inmates as devious were less satisfied with their jobs; however, age and supervisory support positively influenced job satisfaction, whereas job dangerousness and role conflict negatively influenced job satisfaction. Although statistically significant, the association of perceptions of inmates on job satisfaction was small relative to the work environment. The results suggest that correctional administrators need to focus on the work environment, especially supervisory support, to improve correctional staff job satisfaction. (Published Abstract)
