BACKGROUND: Though insomnia is associated with affected emotion regulation and dysfunctional ideas about sleep, little is known about the relation of these problems with objective sleep disruption. We aimed to explore this relationship in young adults with and without insomnia.
METHODS: Twenty young adults with diagnosed insomnia disorder (aged 27.7 ± 8.6 years) and twenty age-matched individuals without insomnia (26.7 ± 7.0 years) completed questionnaires, measuring sleep-related thoughts and emotions and emotion regulation. Objective sleep measurements were collected through 10-days actigraphy as a representative sample of nights, and analyzed for sleep onset latency, sleep efficiency total sleep time. T-tests and multivariate analyses of variance (MANOVA) were conducted for sample characterization and analysis of the association of sleep-related thoughts and emotions and emotion regulation with objective sleep data.
RESULTS: As expected, young people showed more dysfunctional sleep-related thoughts and emotions (all ps ≤ 0.025) and dysfunctional emotion regulation strategies (all ps ≤ 0.040). Surprisingly, MANOVA results showed that only emotion coping strategies after a stressful event (p = 0.017) and dysfunctional beliefs about sleep (p = 0.012), but not other factors of arousal or sleep reactivity, were associated with overall worse sleep, especially sleep onset latency (all ps ≤ 0.012) and sleep efficiency (all ps ≤ 0.010).
CONCLUSIONS: Maladaptive emotion coping strategies after a stressful event and dysfunctional sleep-related beliefs and attitudes affect objective sleep onset latency and sleep efficiency in young adults, highlighting the importance of targeting these features in the prevention and treatment of chronic insomnia and improving actual sleep quality.
