ObjectiveTo explore the mediating effect of uncertainty tolerance between locus of control and work engagement in nurses, and to provide reference for clinical nursing management and training.
MethodsA total of 282 nurses from two hospitals in Chengdu and Deyang of Sichuan province were selected as subjects by convenience sampling method.A general demographic information questionnaire was used to investigate demographic characteristics, the intolerance of uncertainty scale was used to investigate uncertainty tolerance, the Internal Control and Powerful over Others and Opportunities Scale was used to investigate the level of sources of psychological control, the Work engagement Scale was used to investigate work engagement, and the structural equation model was constructed to validate the mediating role of uncertainty tolerance in the relationship between nurses' sources of psychological control and work engagement.
ResultsThe internality, powerful others, chance, intolerance of uncertainty and work engagement were (18.27± 4.52) points, (23.65±5.80) points, (22.86±5.48) points, (31.27±8.72) points, (54.01±8.58) points, respectively.All of them were pairwise correlated (P < 0.01).Multiple regression analysis showed that the locus of control and uncertainty tolerance could explain 41.6% of the work engagement.The results of structural equation model showed that the uncertainty tolerance had a partial mediating effect between the locus of control and work engagement, and the mediating effect accounted for 44.3% of the total effect.
ConclusionsThe locus of control can directly and positively affect the nurses' work engagement or indirectly through the mediating effect of uncertainty tolerance.In nursing management and training, we should pay attention to the relationship between the three, improve the internality level of nurses and the cognition and coping ability of uncertain events, and ensure the level of work engagement.
