Work-family behavioral role conflict and daytime sleepiness on suicide risk among Chinese nurses: A cross-sectional study.

Background: Work-family conflicts and daytime sleepiness are related to the risk of suicide. At present, no study has investigated the relationship between nurses' work-family behavioral role conflict and suicide risk. Moreover, it has not been confirmed whether, considering the effect of daytime sleepiness on suicide risk, daytime sleepiness mediates the effect of work-family behavioral role conflict and suicide risk.
Aim: To explore the pathway relationships among nurses' work-family behavioral role conflict, daytime sleepiness, and suicide risk.
Methods: Convenience and purposive sampling methods were used to select 750 nurses from six provinces, including Jiangxi, Sichuan, and Shanxi. The work-family behavioral role conflict scale, the Chinese adult daytime sleepiness scale, and the suicide behavior questionnaire were used for the survey. The data were statistically analyzed via SPSS 25.0 software, Pearson correlation analysis was used to explore the correlations between the variables, the PROCESS 4.0 program was used for the mediation effect analysis, and the mediation effect model was tested via the bootstrap method.
Results: Nurses' work-family behavioral role conflict and daytime sleepiness were positively correlated with suicide risk ( r = 734, 0.717). Work-family behavioral role conflict positively predicted suicide risk ( β = 0.118), and daytime sleepiness positively predicted suicide risk ( β = 0.152). Daytime sleepiness partially mediated the role of nurses' work-family behavioral role conflict and suicide risk, with a mediation effect value of 0.046 and a mediation effect accounting for 38.98%.
Conclusion: The results of the Pearson correlation analysis and mediation effect analysis revealed that nurses' work-family behavioral role conflict has a direct effect on suicide risk and indirectly affects suicide risk through daytime drowsiness symptoms.
