| Abstract | |
Insomnia is the most prevalent sleep disorder in the adult population. Studies have shown that personality traits, particularly neuroticism, act as factors that predispose to and potentially perpetuate insomnia; however, there is still no consensus in the literature regarding these relationships and their underlying mechanisms. The objectives of this study were to evaluate personality traits in adults with and without insomnia, investigate the association between the big five personality factors and insomnia severity and explore mediating and moderating factors of the association between neuroticism and insomnia. A total of 595 participants (353 individuals com insomnia and 242 controls) answered the Insomnia Severity Index, Revised NEO Five-Factor Inventory, Hospital Anxiety and Depression Scale, a questionnaire containing questions of the Diagnostic and Statistical Manual of Mental Disorders (5th edition), and a sociodemographic questionnaire. Descriptive analysis, correlations and stepwise linear regression were used to assess the associations between the five personality traits and insomnia severity. Mediation and moderation analyses were performed to evaluate the mechanisms underlying the association between insomnia severity and neuroticism. There was a direct negative association between insomnia severity and openness to experience and an indirect positive association between insomnia severity and neuroticism. Anxiety was identified as a mediator and depression as a moderator of the association between insomnia severity and neuroticism. The neuroticism and openness to experience personality traits are significant predictors of insomnia severity. Openness to experience appears to be a protective factor against insomnia. These results encourage the development of new behavioral strategies for the prevention and individualized treatment of insomnia (AU) | |
