Objectives:
This study aimed to identify and validate risk factors for suicidal ideation (SI) and non-suicidal self-injury (NSSI) among nursing staff through the development and application of a risk model and nomogram.
Design:
A cross-sectional online survey was conducted in Dehong District to collect relevant data.
Participants:
A total of 1774 Chinese nursing staff members were enrolled in this study.
Results:
Multiple factors were independently associated with SI among nursing staff. These included divorce or other non-marital status (OR=2.42, 95% CI 1.07 to 5.44), drinking frequency (OR=1.34, 95% CI 1.001 to 1.79), loneliness (OR=1.26, 95% CI 1.11 to 1.44), depressive symptoms (OR=1.13, 95% CI 1.09 to 1.18), childhood trauma (OR=1.03, 95% CI 1.02 to 1.05) and life quality satisfaction (OR=0.63, 95% CI 0.49 to 0.80). Similarly, for NSSI among nursing staff, independent risk factors were identified, such as smoking frequency (OR=1.37, 95% CI 1.01 to 1.85), drinking frequency (OR=1.42, 95% CI 1.05 to 1.91), loneliness (OR=1.21, 95% CI 1.05 to 1.39), depressive symptoms (OR=1.13, 95% CI 1.09 to 1.18) and childhood trauma (OR=1.03, 95% CI 1.01 to 1.05). A nomogram for assessing SI/NSSI was established and demonstrated good calibration, with a Concordance Index of 0.82 (95% CI 0.79 to 0.86) for SI and 0.81 (95% CI 0.78 to 0.85) for NSSI.
Conclusion:
The findings of this study can be used to identify nursing staff at risk of developing SI/NSSI. By using the developed nomograms for self-assessment, individuals might gain a better understanding of their occupational stress levels while performing routine work tasks. However, it should be noted that the study lacks external validation, which limits the generalisability of the findings at this stage.
