Abstract:
Objective To analyze the mediating effect of mental resilience on the relationship between work stress and sleep
quality in psychiatrists. Methods A total of 221 front-line psychiatrists from four mental health centers in Shannxi Province
were selected as the study subjects using convenience sampling method. The questionnaires of Scale for Occupational Stressors
on Clinician，Chinese Version of Connor-Davidson Resilience Scale and Pittsburgh Sleep Quality Index Scale were used to
investigate the work stress，mental resilience and sleep quality of the psychiatrists. We conducted Bootstrap mediation test to
analyze the mediating effect of mental resilience using SPSS PROCESS V3.5 macro program. Results The total score of work
stress of psychiatrists was 97.0±17.5，and the medium（P25，P75）of mental resilience and sleep quality scores were 84.0（75.5，
94.0）and 6.0（5.0，9.0）respectively. The detection rate of sleep disorders among psychiatrists was 33.9%（75/221）. The total
score of work stress of psychiatrists was negatively correlated with the total score of mental resilience ［rank correlation
coefficient（rS
）=−0.34，P<0.01］，and was positively correlated with the total score of sleep quality（rS
=0.48，P<0.01）. The total
score of mental resilience was negatively correlated with that of sleep quality （rS
= − 0.39，P<0.01）. The work stress of
psychiatrists had a positive predictive effect on sleep quality［standardized regression coefficient（β）=0.41.P<0.01］，and a
negative predictive effect on mental resilience（β）=−0.38，P<0.01）. Mental resilience had a negative predictive effect on sleep
quality（β）=−0.24，P<0.01. Mental resilience played a partial mediating role between work stress and sleep quality，and the
mediating effect accounted for 22.0% of the total effect. Conclusion Both work stress and mental resilience of psychiatrists can
directly affect their sleep quality，and the mental resilience has a partial mediating role in the effect of work stress on sleep
quality.
