Utilizing three stepwise multiple regression models, it was found that the prison system in which a correctional officer was employed did not predict job satisfaction. Determinants of job satisfaction were similar for each of the nationality groups. Variables that predicted job satisfaction scores for both American and Canadian correctional officers included work stress, quality of working relationships with other correctional officers, and length of service. For all correctional officers, major determinants of job satisfaction were variables that related to attributes of working in corrections rather than to attributes of individual correctional officers. The only variables related to personal attributes of correctional officers that appeared to affect job satisfaction were educational level (Americans) and marital status (Canadians). 27 references, 5 endnotes, and 3 tables
