Sleep Effort and Insomnia Severity: The Role of Bedtime Procrastination
Uygur Omer Faruk,Bahar Aynur 대한수면학회 2023 sleep medicine research Vol.14 No.1
Background and Objective We aimed to investigate the mediating role of bedtime procrastination in the relationship between sleep effort and insomnia severity in this study.Methods We included 497 university students in this study. All the participants completed the sociodemographic data form, Glasgow Sleep Effort Scale (GSES), Insomnia Severity Index (ISI), Depression-Anxiety-Stress Scale-21 (DASS-21), and Bedtime Procrastination Scale (BPS). We divided the participants into groups, according to their GSES and BPS scores, those with high-low sleep effort and those with BP (+) and BP (-), respectively. We compared the variables in these groups. Finally, we analyzed the mediating role of bedtime procrastination in the relationship between sleep effort and insomnia severity.Results The mean age of the participants was 20.41 ± 1.83 years. ISI, BPS, and DASS-21 were statistically significant in the group with high sleep effort (p < 0.01). Among the psychometric instrument scores, the highest correlation with GSES was with ISI, and then there was a statistically significant positive correlation with DASS-21. In addition, there was a statistically significant positive correlation between GSES and BPS. Bedtime procrastination played a partial mediation role in the relationship between sleep effort and insomnia severity.Conclusions Bedtime procrastination partially mediated the relationship between sleep effort and insomnia severity. Therapists should consider sleep effort and bedtime procrastination on their agenda in cognitive behavioral therapy sessions for insomnia.

Objective Society’s sleep-wake cycle and eating behaviors have altered and are considered the psychological outcomes of the coronavirus disease-2019 (COVID-19) pandemic. Our aim was to examine the relationship between sleep-wake rhythms, eating behaviors (dieting, oral control, and bulimic behaviors), and attention deficit hyperactivity disorder (ADHD) symptoms with weight gain during the COVID-19 pandemic.Methods The participants were 578 female university students divided into three groups based on weight change during COVID-19 who lost weight, whose weight did not change (nWC), and who gained weight (WG). The participants’ information about weight change in the last year and responses to the Pittsburg Sleep Quality Index, Eating Attitudes Test, Adult ADHD Severity Rating Scale, and Wender Utah Rating Scale were collected via an online survey from January 8, 2021 to January 11, 2021.Results The sleep-wake phase was more delayed in WGs than in the other two groups. The bulimic behavior score was higher and the oral control behavior score was lower in the WG group than in the nWC group. A hierarchical regression analysis model, in which weight change scores were dependent variables, showed that mid-sleep time in second step (β=4.71, t=2.18, p=0.03), and oral control (β=-0.11, t=-3.24, p=0.001)/bulimic behaviors (β=0.20, t=3.20, p=0.001) in third step were associated with weight change after controlling for both current and childhood ADHD symptoms.Conclusion Chronotherapeutic approaches that regulate sleep-wake rhythm may facilitate weight control of individuals during stressful periods, such as the COVID-19 outbreak.

Background and Objective We aimed to investigate whether viral anxiety affects insomnia severity in patients with insomnia disorder during the coronavirus disease 2019 (COVID-19) pandemic. In addition, we examined whether viral anxiety mediates the influence of dysfunctional beliefs about sleep on insomnia severity.Methods The medical records of 111 patients who visit the sleep clinic from September 2021 to May 2022 were reviewed. Patients’ symptoms were rated with rating scales including Insomnia Severity Index (ISI), Stress and Anxiety to Viral Epidemics-6 items (SAVE-6), Dysfunctional Beliefs and Attitudes about Sleep-16 items (DBAS-16), Patient Health Questionnaire-9 items (PHQ-9), Epworth Sleepiness Scale, and discrepancy between desired time in bed and desired total sleep time (the DBST index).Results The SAVE-6 score was not significantly correlated with ISI score among insomnia patients. Linear regression analysis showed that the ISI score was expected by PHQ-9 (β = 0.21, p = 0.038) and DBAS-16 (β = 0.42, p < 0.001). Mediation analysis showed that viral anxiety did not mediate the influence of dysfunctional beliefs about sleep on insomnia severity.Conclusions We could not observe the mediating effect of viral anxiety on the association between dysfunctional beliefs about sleep on insomnia severity. Though COVID-somnia was one of big issues in this COVID-19 pandemic, the influence of virus on the severity of insomnia among insomnia patients needs to be interpreted cautiously.
