Objectives: The study aims were to evaluate the emotional well-being of nursing students in Jordan by measuring student levels of anxiety, depression, behavioural control, positive affect, and general distress, and to identify predictors of emotional well-being in nursing students. Background: Owing to a unique number of stressors, nursing students have been shown to experience high levels of stress. This stress may impact their learning, physical health, and mental health, as well as lead to burnout and potentially self-harmful behaviours. Identifying the predictors of psychological distress among nursing students is therefore critical. Method: A descriptive cross-sectional survey design was utilised. The Mental Health Inventory (MHI-38) was administered to a convenience sample of nursing students (n = 230) from a university in Jordan. Multiple regression analysis was performed to determine predictors of psychological distress and well-being. In presenting this research, the STROBE checklist was followed. Results: Nursing students had higher levels of psychological distress and moderate levels of emotional well-being. Nursing students scored high on general positive affect; however scores on domains related to the loss of behavioural/emotional control and anxiety were also high. Discussion: A significant proportion of nursing students within this study were experiencing psychological distress. Implications for practice: This study may be the first to evaluate the emotional well-being among nursing students in Jordan. Research evidence can inform decision makers in that they devise strategies and interventions that aim to build students’ coping skills and promote emotional well-being.
