“…Though single item has been found to have optimal concurrent validity to assess sleep quality, there is a possibility that persons with poor sleep quality have preferred to respond to survey over persons with good sleep quality. [ 11 ] Finally, the prevalence of poor sleep quality was greater than insomnia in the present study because both are different constructs. Considering that sleep quality may be affected by a number of other sleep disorders, besides insomnia, poor sleep quality has been removed from the diagnostic criteria of insomnia disorder.…”

Introduction: To mitigate the spread of the pandemic coronavirus infection (COVID-19), governments across the world have adopted “lockdowns” which have confined many individuals to their homes. This disrupts normal life routines, elements of which are important circadian cues. The pandemic is also associated with new stressors, altered roles, and uncertainties about health and economic security, which are also likely to affect sleep. The current study is an online survey of sleep experience, routines, physical activity, and symptoms of anxiety and depression, to study the alterations associated with the lockdown. Materials and Methods: The survey was conducted in early May 2020 using a questionnaire circulated through social media platforms. Questions related to demographic characteristics, current and previous sleep schedules, routine, and working patterns. Insomnia (Insomnia Severity Index - 4), Stress (Perceived Stress Scale - 4), anxiety and depressive symptoms (Patient Health Questionnaire - 4) and physical activity (International Physical Activities Questionnaire) were assessed using standardized instruments. Results: A total of 958 valid responses were received. Compared to the prelockdown period, there was a shift to a later bedtime and waking time, with a reduction in night-time sleep and an increase in day-time napping. These effects were visible across occupational groups, but mostly affected working individuals except health professionals. Sleep quality deteriorated across groups. Reductions in sleep duration were associated with depressive symptoms. Conclusions: The COVID-19 lockdown is associated with changes in sleep schedule and in the quantity and quality of night-time sleep. Although these changes are associated with elevated rates of emotional symptoms, it is unclear from these cross-sectional results, whether sleep deterioration produces psychological distress, or vice versa.

“…Despite the comprehensiveness of this systematic review, the time elapsed between the initial database search and the publication of the results is an important limitation. To address this, a supplementary literature search using the same search strategy and databases was undertaken in April 2020, which identified additional validation studies and 7 new instruments including: the Insomnia Catastrophising Scale (ICS), 82,83 the Singleitem sleep quality scale (SQS), 84 the Lebanese insomnia scale (LIS-18), 85 the Daytime Sleepiness Perception Scale-4 (DSPS-4), 86 the Indian Sleepiness Scale (InSS), 87 Athlete Sleep Behavior Questionnaire (ASBQ), 88 and the Non-restorative Sleep Scale (NRS) 89 . These findings are indicative that the improvement in scientists' understanding of insomnia pathophysiology has been associated with a parallel increase in the development of instruments which measure different aspects of sleep dysfunction and related risk factors.…”

Introduction: Self-reported sleep instruments remain the most practical methods for the assessment of insomnia in clinical practice. This systematic review aims to identify, describe and summarize the psychometric properties of questionnaires available for the assessment of insomnia in the adult population. In addition, the review also aimed to identify sleep instruments available in the Arabic language. Methods: A systematic literature search was conducted using the following electronic databases: PubMed, EMBASE, ProQuest Central, SCOPUS, and Google Scholar. The quality assessment of the instruments was conducted using two established international criteria. Results: One hundred and seven articles were selected for inclusion, from which 31 instruments were identified and categorized based on the constructs they assess as: (1) screening for insomnia (n=14); (2) measuring the consequences of insomnia (n=8); (3) assessing the cognitive aspects of insomnia (n= 5); and (4) assessing sleep hygiene (n= 4). The review of the psychometric properties showed that the Insomnia Severity Index and the Functional Outcomes of Sleep Questionnaire were the most extensively evaluated instrument. Criterion validity and reliability measures were the most commonly reported properties. Only four of the identified instruments were available in Arabic. Discussion: Overall, the findings of this study indicate ample availability of sleep instruments. However, psychometric testing for several of the available sleep instruments remains incomplete, particularly responsiveness and interpretability. Our findings suggest that future studies should focus on reporting more psychometric measures to ensure the trustworthiness of these instruments.

“…Scores were averaged into a single index, r = .81, p < .001. Lastly, participants indicated their perceived physical health (1 = Poor to 5 = Excellent; Ware et al, 1996) and the quality of their sleep (1 = Terrible to 5 = Excellent; Snyder et al, 2018). Throughout the survey, participants were reminded of questions left unanswered, but were allowed to proceed with the survey.…”

The pandemic caused by the novel coronavirus (COVID-19) has forced the world into social isolation and confinement for health and safety reasons. Such changes affected the way people connect with each other, which had repercussions on health and well-being. Since the COVID-19 outbreak, researchers have been striving to understand the effects of the pandemic at social, personal and relational levels. Some people have experienced heightened sexual desire and made new additions to their sexual repertoire. We extended these findings by examining the personal and relational outcomes of joint and solitary online pornography use. Results from a cross-sectional study (N = 301 participants; 56.5% men; Mage = 31.36, SD = 10.57) showed that participants indicated adherence to confinement policies, changes in lifestyle, and fear of becoming infected with COVID-19. Participants also indicated decreased sexual desire since the outbreak, but also increased willingness to have sex. Results also showed that joint pornography use was associated with more sex quality and more satisfaction and intimacy with their partners, which in turn was associated with better perceived physical health and better sleep quality. The reverse pattern was found for solitary pornography use. Lastly, overall results were consistent for single and pattered people. These findings show the personal and relational benefits of using online pornography with partners use during the pandemic.
