Background Many university students have difficulties with sleep; therefore, effective psychological treatments are needed. Most research on psychological treatments to improve sleep has been conducted with middle-aged and older adults, which means it is unclear whether existing psychological treatments are helpful for young adult university students. Objective This study aimed to discover university student preferences for a psychological intervention to improve sleep quality. Methods Focus groups were conducted over 3 stages to examine students’ views regarding content, format, and session duration for a psychological intervention to improve sleep. A thematic analysis was conducted to analyze participant responses. Results In total, 30 participants attended small focus group discussions. Three key themes were identified: (1) program development, (2) help-seeking, and (3) student sleep characteristics. Program development subthemes were program format, program content, and engagement facilitators. Help-seeking subthemes were when to seek help, where to access help, stigma, and barriers. Student sleep characteristics subthemes were factors disturbing sleep and consequences of poor sleep. Conclusions Students emphasized the need for a sleep intervention with an in-person and social component, individualized content, and ways to monitor their progress. Participants did not think there was a stigma associated with seeking help for sleep problems. Students identified the lack of routine in their lifestyle, academic workload, and the pressure of multiple demands as key contributors to sleep difficulties.

“…We consider a score of 15 or above as moderate or severe insomnia. This scale has shown great reliability and validity in a previous meta-analysis [ 18 ]. Excessive daytime sleepiness (EDS) was measured using the Epworth Sleepiness Scale (ESS), a validated scale exploring eight everyday situations rated on a 4-point Likert scale ranging from “would never doze” to “high chance of dozing”.…”

Healthcare workers often have irregular work schedules and experience significant stress, which can lead to poor sleep quality and frequent mental health issues, especially in the context of the COVID-19 pandemic. In this cross-sectional study, we aimed to assess the prevalence of poor sleep hygiene and mental health complaints among healthcare workers and examine their associations. We investigated participants’ typical sleep–wake patterns on workdays and free days as indicators of sleep hygiene. Sleep efficiency and social jetlag were calculated as the ratio of mean sleep duration to time spent in bed, while sleep rebound was defined as the difference in mean sleep duration between workdays and free days. Social jetlag was determined as the difference in mid-sleep timing between workdays and free days, with mid-sleep defined as the midpoint between bedtime and wake-up time. Insomnia severity was assessed using the Insomnia Severity Index (ISI), daytime sleepiness using the Epworth Sleepiness Scale (ESS), and symptoms of anxiety and depression using the Patient Health Questionnaire 4 (PHQ-4). Fatigue was measured using a single item inspired by the Maslach Burnout Inventory (MBI). A total of 1562 participants (80.5% women, mean age 40.0 years) were included in the study. The results revealed that 25.9% of participants slept less than 6 h, 24.3% had a sleep efficiency of less than 85%, 27.3% experienced a sleep rebound of more than 2 h, and 11.5% reported a social jetlag exceeding 2 h. Additionally, 33.9% of participants reported insomnia, 45.1% reported excessive daytime sleepiness, 13.1% reported fatigue, 16.5% reported symptoms of depression, and 35.7% reported symptoms of anxiety. After adjustment, mean sleep duration and sleep efficiency were associated with most mental health complaints. Sleep rebound and social jetlag were associated with significant insomnia but not with anxiety or depression symptoms. Our findings underscore the high prevalence of poor sleep hygiene and mental health complaints among healthcare workers, exacerbated by the COVID-19 crisis. We advocate for the promotion of sleep health through behavioral sleep strategies to safeguard the well-being of healthcare professionals.

“…The Insomnia Severity Index (ISI) was used to screen for poor sleep and measure symptoms of insomnia. The ISI is a valid measure that demonstrates good internal consistency (Cronbach's alpha = 0.83; Cerri et al, 2023) and has been used as both a screening and outcome measurement tool in clinical and nonclinical samples, including post-secondary students (Morin, 1993;Lukowski and Tsukerman, 2021). The ISI consists of seven items assessing the severity of insomnia problems that are graded on a scale from 0 to 4 (none = 0, mild = 1, moderate = 2, severe = 3, very = 4).…”

IntroductionPoor mental health is a known risk factor for poor sleep among university students; however, less is known about the role of dysfunctional sleep beliefs and its relation to mental health and sleep. Additionally, students who identify as people of color (POC) may experience unique stressors related to discrimination and inequalities which can contribute to mental health issues and in turn, influence their sleep. The present study evaluated the impact of dysfunctional sleep beliefs and poor mental health on a student's susceptibility to worse sleep and examined differences among POC.MethodsPost-secondary students completed a survey including the Insomnia Severity Index and the Dysfunctional Beliefs and Attitudes about Sleep Scale. Participants also completed questionnaires measuring symptoms of depression, anxiety, and perceived stress.ResultsOne thousand five hundred and sixty-two students were included in the analyses, 58% of which were POC. POC students had more dysfunctional sleep beliefs (p < 0.01) and worse insomnia severity (p < 0.01) compared to white students. Overall, greater dysfunctional sleep beliefs were significantly associated with worse symptoms of depression (b = 1.521), anxiety (b = 1.170), stress (b = 1.370), and poor sleep (b =1.963; ps < 0.001). Dysfunctional sleep beliefs also moderated the relation between poor mental health and sleep, specifically depression (p = 0.035) and anxiety (p = 0.007), by exacerbating sleep outcomes.DiscussionThe results suggest that dysfunctional sleep beliefs may play a role in perpetuating poor mental health and sleep. Interventions to improve students' sleep and wellbeing focused on reframing dysfunctional sleep beliefs should be examined.
