Comparison of dream anxiety and subjective sleep quality between chronotypes

Abstract

Morning and evening-type individuals differ on a number of psychological and biological variables. In this study, we aimed to investigate the relationship between sleep quality, dream anxiety, and chronotypes. A sample of 264 university students, aged between 17 and 26 years, completed the Morningness-Eveningness Questionnaire, the Pittsburgh Sleep Quality Index, and the Van Dream Anxiety Scale for assessing nightmare frequency and the dream anxiety caused by frightening dreams. Main findings indicated that evening-type individuals were significantly more likely to suffer from poor sleep quality, daytime dysfunction, nightmares, and nightmare-related disturbances as compared to either intermediate-or morning-type individuals. Previous studies have pointed out the possible connections of irregular sleep-wake habits and circadian dysregulation with a tendency to reveal eveningness chronotypical characteristics. Current findings suggest that evening-type individuals are more prone to experience psychologically deteriorating nightmares and sleep-related anxiety. Poor sleep quality is also a significant antecedent of dream anxiety after controlling for age and gender.

Sleep Habits And Chronotype Effects On Academic And Cognitive Performance İn Spanish Adolescents: A Review

“…For this reason, this stage of life means both developmental and social changes which may be stressful to most of students. Evening types suffer from higher levels of anxiety, obsessive-compulsiveness, hostility and phobia symptoms (Vardar, Vardar, Molla, Kaynak & Ersoz, 2008) and usually have nightmares and suffer from dream anxiety (Selvi et al, 2012). Linked to physical, psychological and social changes, evening type adolescents are forced to adapt their biological preferences to the early school schedules, consequently, morningness-eveningness may be a risk factor to consider concerning health and anxiety symptoms during this stage of life.…”

Sleep–wake pattern, chronotype and seizures in patients with epilepsy

“…Circadian dysregulation between individual chronotype and daily activity are known to cause http://dx.doi.org/10.1016/j.eplepsyres.2015.11.010 0920-1211/© 2015 Published by Elsevier B.V. sleep problems. One study showed that individuals with a circadian preference for evening activities (evening-type) showed higher prevalence of sleep disturbance than morningness or intermediated-type (Selvi et al, 2012). Homeostatic changes in sleep deprivation, as well as different individual chronotype can cause sleep disorders.…”

Evening-type military veterans report worse lifetime posttraumatic stress symptoms and greater brainstem activity across wakefulness and REM sleep

“…Recent evidence also links eveningness to more frequent and intense nightmares (Nielsen, 2010; Selvi et al, 2012). This link suggests that the affective dysregulation, which characterizes evening-types' waking state, may also extend to the rapid-eye movement (REM) sleep state during which nightmares primarily occur.…”
