Abstract
|
|
|
|
This study aimed to identify psychological characteristics in insomnia patients with Minnesota Multiphasic Personality Inventory-2 (MMPI-2). All participants including insomnia patients without other sleep disorders (PPI), insomnia patients with Obstructive Sleep Apnea (OSA-I) and healthy controls (CON) underwent polysomnography and completed Epworth Sleepiness Scale (ESS), Beck Depression Inventory (BDI) and Minnesota Multiphasic Personality Inventory-2 (MMPI-2). Insomnia patients with and without OSA had significantly higher scores on the depression scales and were more likely to report psychopathological symptoms compared to CON. PPI patients had a higher risk of developing psychotic features and also tend to be more introverted compared to CON. Additionally, Aggression differentiated PPI from OSA-I and CON. These findings suggest that psychological factors in insomnia patients may be linked to hyperarousal state and can be vulnerability to insomnia. Current study would be helpful to prevent and treat insomnia by considering psychological traits of insomnia patients.
