Introduction: This study aimed at examining the psychometric properties of Work Stress Scale for Correctional Officers (WSSCO). Methods: One hundred nineteen correctional officers (109 males and 10 females) employed in Turkey participated in this study. In addition to WSSCO, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Beck Hopelessness Scale (BHS), and Multidimensional Scale of Perceived Social Support (MSPSS) were administered to the participants. Results: The internal consistencies and the item-total correlations were acceptable both for the whole scale and for its subscales; namely, "work overload," "role conflict and role ambiguity," "inadequacies in physical conditions of prison," "threat perception," and "general problems." Test-retest reliability coefficient was 0.77 for total scale, and test-retest reliability coefficients ranged between 0.68 and 0.78 for the subscales. The total scale and most of the subscales were positively correlated with depression, anxiety, and hopelessness, and negatively correlated with perceived social support. Furthermore, all subscales significantly differentiated high depressive symptomatology group from the low depressive symptomatology group. Conclusions: The present results revealed that the psychometric properties of WSSCO were quite adequate. The scale can provide a potentially useful tool for research on job stress in correctional officers.
