Investigating the mediating role of insomnia in the link between individual resources and psychological well-being during times of crisis

This study investigates the association between locus of control, emotional intelligence, and psychological well-being, with insomnia as a mediating factor. Data was collected in Lebanon from 328 workers (60.7% women; mean age = 33.17) over a 6-month period in 2022. Regression-based mediation analyses revealed that internal locus of control was linked to lower insomnia and, in turn, greater psychological well-being. Emotional intelligence showed no significant effects. Exploratory analyses indicated that the "use of emotion" dimension of emotional intelligence was associated with increased insomnia and, indirectly, with lower psychological well-being. These findings underscore the nuanced role individual resources play in shaping health outcomes. More specifically, not all individual resources have uniformly positive effects. Given the potentially detrimental impact of the "use of emotion" dimension, interventions should prioritize strengthening internal locus of control and encouraging more constructive and balanced use of emotion strategies to reduce insomnia and enhance psychological well-being.
