Background:
In spite of the major role of early maladaptive schemas in vulnerability to various psychological disorders, studies about the relationship between early maladaptive schemas and insomnia disorder are scarce. Hence, the aim of the current study was to explore the contribution of early maladaptive schemas in insomnia severity by comparing a sample of patients with chronic insomnia and good sleepers.
Methods:
Patients with chronic insomnia and good sleepers were evaluated using Young Schema Questionnaire-Short Form (YSQ-SF), Depression Anxiety and Stress Scale (DASS-21), and Insomnia Severity Index (ISI).
Results:
The study enrolled 117 patients with chronic insomnia and 76 good sleepers. All early maladaptive schemas (EMSs) except for enmeshment showed significant correlations with insomnia severity. After controlling for depression/anxiety symptoms, logistic regression analysis showed that the EMSs including emotional deprivation, vulnerability to harm, and subjugation schemas were significantly associated with insomnia severity.
Conclusions:
These preliminary findings suggest that EMSs may constitute a vulnerability factor for developing insomnia. Early maladaptive schemas may require attention in the existing treatments of insomnia.
