School-based sleep education programs: A knowledge-to-action perspective regarding barriers, proposed solutions, and future directions

A sleep promotion program for insufficient sleep among adolescents: a pilot feasibility randomized controlled trial

STUDY OBJECTIVES

We examined the feasibility, acceptability, and impact of a sleep promotion program (SPP).

METHODS

This pilot trial randomly assigned adolescents (13-15 years of age) with insufficient sleep duration and irregular sleep timing to SPP-continuation (n = 24; SPP in month 1, continuation treatment in month 2) or monitoring-SPP (n = 20; monitoring in month 1, SPP in month 2). SPP included 1 clinician session and at-home delivery of web-based reports of each youth's sleep diary data with accompanying intervention questions that prompt youth to engage in sleep behavior change. Attrition rate primarily measured feasibility. Program satisfaction measured acceptability. Total sleep time, sleep timing, and sleep timing regularity were measured via sleep diary at baseline, Follow-up 1, and Follow-up 2 (each ∼1 month apart). Linear mixed-effects models compared treatment arms on changes in sleep from baseline to Follow-up 1 (month 1). We also compared changes in sleep during month 1 to changes in sleep during month 2 among SPP-continuation participants.

RESULTS

Attrition rate was 8.5%, and 96.5% of participants rated the quality of care received as good or excellent. In month 1, SPP-continuation youth showed a significantly greater increase in mean total sleep time than monitoring-SPP youth (0.57 vs -0.38 hours; contrast = 0.95; confidence interval = 0.14, 1.76; P = .024). SPP-continuation participants showed an increase in total sleep time during month 1 (0.51 hours) but a decrease during month 2 (-0.74 hours; contrast = -1.24; confidence interval = -2.06, -0.42; P = .005). No other significant effects were observed.

CONCLUSIONS

SPP is highly feasible, acceptable, and associated with a significant increase in total sleep time early in treatment.

Advancing adolescent bedtime by motivational interviewing and text message: a randomized controlled trial

BACKGROUND

Sleep deprivation is a prevalent problem among adolescents which is closely related to various adverse outcomes. The lack of efficacy of current sleep education programs among adolescents argues for the need to refine the content and format of the intervention. This study aimed to evaluate the effectiveness of a group-based sleep intervention using motivational interviewing plus text reminders in changing adolescent sleep habits.

METHODS

This study is a randomized controlled trial comparing motivational group-based sleep intervention with nonactive control group. The primary outcomes were the sleep-wake patterns measured by both sleep diary and actigraphy at postintervention, 3 and 6 months after the intervention. The trial was registered with the Clinical Trial Registry (NCT03614572).

RESULTS

A total of 203 adolescents with school day sleep duration of <7 hr (mean age: 15.9 ± 1.0 years; males: 39.9%) were included in the final analysis. Sleep diary and actigraphy data both showed that adolescents in the intervention group had earlier weekday bedtime at postintervention (sleep diary: estimated mean difference: 33.55 min, p = .002; actigraphy: 33.02 min, p = .009) and later wake-up time at 3-month follow-up compared to the control group (sleep diary: -28.85 min, p = .003; actigraphy: -30.03 min, p = .01), and the changes in diary measured weekday bedtime were sustained up to 6-month follow-up. In addition, adolescents in the intervention group had longer sleep diary reported weekday sleep duration at 3- (35.26 min, p = .003) and 6-month follow-up (28.32 min, p = .03) than the controls. Adolescents in the intervention group also reported improved daytime alertness postintervention, which was maintained at the 6-month follow-up.

CONCLUSIONS

The motivational group-based sleep intervention is effective in advancing bedtime with improved sleep duration and daytime alertness in sleep-deprived adolescents.

Efficacy of brief behavioral and sleep hygiene education with mindfulness intervention on sleep, social jetlag and mental health in adolescence: a pilot study

OBJECTIVES

Sleep is often compromised in adolescents, affecting their health and quality of life. This pilot-study was conducted to evaluate if implementing brief-behavioral and sleep-hygiene education with mindfulness intervention may positively affect sleep-health in adolescents.

METHOD

Participants in this community-based non-randomized cohort-study volunteered for intervention (IG)- or control-group (CG). Sleep was recorded during regular school-schedule for 3-school-nights and 2-non-school-nights with an FDA-cleared/EU-Medical Device Regulation (CE-2862) compliant home sleep test, and Questionnaires were utilized to evaluate chronotype, sleepiness, insomnia-, anxiety- and depression-symptoms. The four-week intervention included sleep-hygiene education, mindfulness- and breathing-practices for one-hour, twice weekly. Data was collected during the last-week of February and first two-weeks of March 2023 and repeated after intervention.

RESULTS

Fifty-five participants completed the study, IG (86%) and CG (77%). Average age was 17.3-years and prevalence of severe social-jetlag (SJL) 72%. Participants who quit participation (n = 10) after baseline data-collection all females (3-IG/7-CG) in comparison to participants who completed the study were sleepier than the IG and CG (+ 2.6-p = 0.04; + 3.8-p = 0.001), with more symptoms of insomnia- (+ 3.8-p = 0.002; + 4.7-p < 0.0001), and depression (+ 16.7-p < 0.0001; + 19.6-p < 0.0001), and report being later-chronotypes, (-18.2, p < 0.0001;-13.1, p < 0.0001). On average the IG advanced sleep-onset (32-min; p = 0.030), decreased SJL (37-min; p = 0.011) and increased total sleep time (TST, 29-min; p = 0.088) compared to the CG. Average sleep duration did not differ significantly comparing IG and CG after intervention. Stratifying participants with severe SJL (> 2-h) at baseline; 1) responders (61%) advanced sleep-onset on non-school-nights (96-min) and decreased SJL (103-min; p < 0.001) 2) non-responders (39%) increased sleep-duration on school-nights (36-min) and non-school-nights (63-min) but maintained severe-SJL.

CONCLUSION

Teacher-lead sleep-education and mindfulness program can improve TST and SJL in adolescence.

Students', parents' and teachers' perspectives on comprehensive school-based sleep promotion

Objective

Sleep deprivation is common among children and schools are ideal settings in which to influence children's sleep. Children spend a significant amount of time at school during key developmental periods, and programmes that influence students' well-being also benefit academic achievement. Comprehensive School Health (CSH) is an approach that prioritises school, home and community partnerships by supporting the development of health behaviours. However, sleep is often unaddressed in the school environment. The objective of this study was to integrate multiple partner perspectives to inform how to strengthen school-based sleep promotion using a CSH approach.

Design

A secondary qualitative analysis of student aged 9-11 (n = 45), parent/guardian (n = 24) and teacher (n = 19) interviews from participants representing elementary (Kindergarten - Grade 6) schools and communities in Alberta, Canada was conducted. Data were examined using an a priori framework in alignment with the four components of the CSH approach: social and physical environment, teaching and learning, policy and partnerships and services. Inductive content analysis was used to develop categories followed by subthemes within each CSH component.

Results

Subthemes identified within each component were as follows: social and physical environment (culture of healthy sleep habits; students influence each other); teaching and learning (formally integrate sleep-specific learning into curricula; school, teacher and parents/guardian collaboration); policy (sleep-positive classroom policies) and partnerships and services (community partnerships; school-home collaboration).

Conclusion

This research identifies recommendations from student, parent/guardian and teacher interviews to inform and strengthen school-based sleep promotion when taking a CSH approach. Findings can support school partner efforts to foster a school culture (or ethos) of healthy sleep habits leading to improvements in student sleep behaviours.

A Person-Based Web-Based Sleep Intervention Aimed at Adolescents (SleepWise): Randomized Controlled Feasibility Study

BACKGROUND

Adolescents are advised to sleep 8-10 hours per night; however, most do not sleep for this recommended amount. Poor adolescent sleep is associated with detrimental health outcomes, including reduced physical activity, risk-taking behaviors, and increased depression and anxiety levels, making this an important public health concern. Existing interventions targeting adolescent sleep are often unsuccessful or their effectiveness unclear, as they are frequently noninteractive, time-consuming, and lack a strong theoretical foundation; highlighting an urgent need for innovative interventions deemed acceptable by adolescents.

OBJECTIVE

The main objective of this study was to determine the acceptability, feasibility, and preliminary impact of a web-based person-based sleep intervention (SleepWise) on adolescent sleep quality. Participant incentivization was also explored to understand its impact on engagement, acceptability, and sleep quality.

METHODS

A feasibility trial was conducted to test the feasibility, acceptability, and preliminary impact of SleepWise on adolescent sleep quality, developed based on the person-based approach to intervention development. In total, 90 participants (aged 13-17 years) from further education institutions and secondary schools were recruited for two 2-arm randomized controlled trials. One trial (trial 1) was incentivized to understand the impact of incentivization. Acceptability and sleep quality were assessed via questionnaires, and a mixed methods process evaluation was undertaken to assess participant engagement and experience with SleepWise. Engagement was automatically tracked by SleepWise, which collected data on the date and time, pages viewed, and the number of goals and sleep logs completed per participant. Semistructured interviews were carried out to gain participant feedback.

RESULTS

Participants in both trials reported high levels of acceptability (trial 1: mean 21.00, SD 2.74; trial 2: mean 20.82, SD 2.48) and demonstrated similar levels of engagement with SleepWise. Participants in trial 1 viewed slightly more pages of the intervention, and those in trial 2 achieved their set goals more frequently. Improvements in sleep quality were found in both trials 1 and 2, with medium (trial 1) and large (trial 2) effect sizes. A larger effect size for improvement in sleep quality was found in the nonincentivized trial (d=0.87), suggesting that incentivization may not impact engagement or sleep quality. Both trials achieved acceptable recruitment (trial 1, N=48; trial 2, N=42), and retention at 5 weeks (trial 1: N=30; trial 2: N=30). Qualitative findings showed that adolescents lead busy lifestyles, which may hinder engagement; however, participants deemed SleepWise acceptable in length and content, and made attempts at behavior change.

CONCLUSIONS

SleepWise is an acceptable and potentially efficacious web-based sleep intervention aimed at adolescents. Findings from this study showed that incentivization did not greatly impact engagement, acceptability, or sleep quality. Subject to a full trial, SleepWise has the potential to address the urgent need for innovative, personalized, and acceptable sleep interventions for adolescents.

Adolescents' Suggestions on how to Support Their Sleep: A Focus Group Study

Sleeping difficulties among adolescents constitute a pressing public health issue, and it is of the utmost importance that these are approached from a health-promotion perspective. This study explores adolescents' suggestions on how their sleep could be supported. Data were collected via eight focus group interviews with 43 adolescents aged 15-16, in Sweden, and analyzed using qualitative content analysis. The results describe the adolescents' suggestions on how their sleep could be supported in three themes: being supported by involved parents- routines, engagement, and warmth are vital; being supported to achieve knowledge on the "whys" and "hows" of sleep-increased knowledge gives the ability to make well-grounded sleep choices; and being guided into finding balance-balance in life is difficult to achieve and adolescents desire support. Parents, school nurses, health professionals, and anyone who has the opportunity to improve and promote sleep should consider adolescents' suggestions.

"I'm not sure if it works": School nurses' experiences of sleep-promoting work in Sweden

OBJECTIVES

Lack of sleep is a common problem in children and adolescents of school age (students), and it is a health aspect that affects the ability to assimilate into the school's education and thereby falls within the school nurses promoting work. This study aimed to describe school nurses' experiences of sleep-promoting work.

METHOD

Data were collected by n = 61 school nurses' written narratives of their sleep-promotion work. Data were analyzed using qualitative content analysis.

RESULTS

The results describe school nurses' experiences of sleep-promoting work in three main categories: (1) Informing and providing knowledge is the primary task. School nurses do it systematically, through dialogs with an individual student, with several students simultaneously, or with parents. (2) Benefits take place when the needs of the student guide the work. Through curiosity about the personal story, the keys to sleep-promoting work can be found, appropriate strategies can be given, and the student can be guided further if needed. (3) Barriers challenge the outcome of the work. The school nurses experience these barriers in the form of unmotivated students, unsupportive parents, and lack of prerequisites, which make the school nurses unsure of their performance.

CONCLUSIONS

School nurses experience a significant benefit in their sleep-promoting work when the needs of the student guide the sleep-promoting information, strategies, and follow-ups. To avoid feeling insecure in sleep-promoting work, school nurses need updates on the state of knowledge and evidence-based tools. Further research on sleep-promoting work at school is necessary.

"Your Kid Has Potential, But They Need Sleep": Teacher Perspectives on School-Based Sleep Promotion in Alberta, Canada

BACKGROUND

Insufficient sleep is a growing public health concern. Thirty percent of Canadian children and youth are not meeting national sleep recommendations. Inadequate sleep can negatively influence students' academics and physical and psychosocial health. Schools have been identified as ideal health promotion settings to influence children's health including their sleep behaviors. The objective of this study was to explore teachers' perspectives on sleep behaviors and their role in school-based sleep promotion.

METHODS

Nineteen elementary teachers were purposively sampled from the greater Edmonton area, Alberta, Canada. Interpretive description was used as the guiding method, and data were generated through one-on-one semi-structured interviews. Inductive descriptive thematic analysis was used to identify interview themes.

RESULTS

Three themes related to teachers' perspectives on sleep behaviors and school-based sleep promotion were identified: the importance of students' sleep, prioritizing sleep as part of teaching and learning, and a culture of healthy sleep habits.

CONCLUSIONS

This study found that teachers considered sleep to be essential for elementary students' academic success and wellbeing, and a whole school approach was necessary to support a healthy sleep culture in schools.

Common Childhood Sleep Problems and Disorders

BACKGROUND

Sleep insufficiency and disturbances affect the physical, cognitive, and emotional well-being of children.

OBJECTIVE

To perform a narrative review on common sleep problems and disorders encountered in primary care for children and adolescents.

METHODS

A search of English literature in the Pubmed and Google Scholar databases published from 1 January 2000 till 31 October 2021 was conducted with the keywords "sleep problem" or "sleep disorder" and "child" or "adolescent". Findings in the relevant articles and cross-references were compiled.

RESULTS

Sleep duration and habits of children vary widely across countries with different cultural backgrounds. There is robust evidence to support the promotion of positive bedtime routines and sleep hygiene as prevention and management of sleep problems. 15-70% of parents reported their children having sleep problems or disturbances. Common sleep complaints include difficulty in initiation or maintenance of sleep, abnormal behaviors or movements, snoring or abnormal breathing, and excessive daytime sleepiness. Comprehensive sleep history and a sleep diary are the first steps for evaluation. Home video and actigraphy may be used as preliminary tools to confirm the history. Referrals to a sleep specialist for polysomnography and other tests are needed, if suspecting specific sleep disorders, such as obstructive sleep apnea and narcolepsy, needs timely intervention. Common sleep disorders in different age groups encountered in primary care are reviewed with clinical features, indications for evaluation, and treatment options summarized.

CONCLUSION

Screening for sleep problems shall be an integral part of each child's health care visit. It is important to evaluate the impact of common sleep problems and identify specific sleep disorders for early intervention to prevent long-term adverse outcomes.

Pediatric sleep: current knowledge, gaps, and opportunities for the future

This White Paper addresses the current gaps in knowledge, as well as opportunities for future studies in pediatric sleep. The Sleep Research Society's Pipeline Development Committee assembled a panel of experts tasked to provide information to those interested in learning more about the field of pediatric sleep, including trainees. We cover the scope of pediatric sleep, including epidemiological studies and the development of sleep and circadian rhythms in early childhood and adolescence. Additionally, we discuss current knowledge of insufficient sleep and circadian disruption, addressing the neuropsychological impact (affective functioning) and cardiometabolic consequences. A significant portion of this White Paper explores pediatric sleep disorders (including circadian rhythm disorders, insomnia, restless leg and periodic limb movement disorder, narcolepsy, and sleep apnea), as well as sleep and neurodevelopment disorders (e.g. autism and attention deficit hyperactivity disorder). Finally, we end with a discussion on sleep and public health policy. Although we have made strides in our knowledge of pediatric sleep, it is imperative that we address the gaps to the best of our knowledge and the pitfalls of our methodologies. For example, more work needs to be done to assess pediatric sleep using objective methodologies (i.e. actigraphy and polysomnography), to explore sleep disparities, to improve accessibility to evidence-based treatments, and to identify potential risks and protective markers of disorders in children. Expanding trainee exposure to pediatric sleep and elucidating future directions for study will significantly improve the future of the field.

A longitudinal investigation of sleep hygiene as a mediator linking parental warmth with adolescent sleep

STUDY OBJECTIVES

Parental warmth in adolescence protects sleep in early adulthood, yet the nature, directions, and mechanisms of this association across adolescence are unknown. This study examined parental warmth, adolescent sleep hygiene and sleep outcomes (morning/eveningness, school night sleep duration, and daytime sleepiness) across five annual waves, spanning four years, using a cross-lagged panel design.

METHODS

Adolescents and one primary caregiver (96% mothers) completed questionnaires assessing parental warmth (child- and parent-report) and adolescent sleep hygiene and sleep (child-report), across five annual waves: Wave 1 (N = 531, Mage = 11.18, SD = 0.56, 51% male), Wave 2 (N = 504, Mage = 12.19, SD = 0.53, 52% male), Wave 3 (N = 478, Mage = 13.19, SD = 0.53, 52% male), Wave 4 (N = 440, Mage = 14.76, SD = 0.47, 51% male), and Wave 5 (N = 422, Mage = 15.75, SD = 0.49, 51% male).

RESULTS

Greater child-reported parental warmth was indirectly associated with better adolescent sleep (greater morningness, longer school night sleep duration, less sleepiness) through healthier sleep hygiene. The inverse was also often observed. Warmth had a direct relationship with sleep duration and sleepiness, independent of sleep hygiene. Parent-reported parental warmth did not predict, nor was predicted by child-reported adolescent sleep.

CONCLUSIONS

Parental warmth may protect against developmental changes in adolescent sleep, partially by improving sleep hygiene practices. Similarly, inadequate adolescent sleep may negatively impact parental warmth via deteriorating sleep hygiene. Sleep hygiene emerged as a key mechanism for protecting adolescent sleep and parent-child relationships.

Bridging the gap: leveraging implementation science to advance pediatric behavioral sleep interventions

STUDY OBJECTIVES

This review synthesizes the pediatric behavioral sleep intervention (BSI) evidence base, summarizes challenges in translating BSIs from research to practice, and provides recommendations for integrating implementation science methods to advance pediatric BSI research.

METHODS

We briefly review the common behavioral sleep disturbances among youth, discuss the pediatric BSIs with well-established evidence, and identify gaps in pediatric BSI research. We then identify contributors to the dearth of research evaluating pediatric BSIs in accessible settings and present a model for applying implementation science strategies to address identified gaps across the continuum of translational research.

RESULTS

Relatively few BSI trials include older children and adolescents. Similarly, there is limited research evaluating BSIs among racially and ethnically minoritized children and families and/or those of lower socioeconomic status backgrounds. Access to scalable and easily disseminable tools to treat pediatric sleep disturbances early in their development is crucial for promoting positive child outcomes. To address these gaps, researchers should apply implementation science theories, models, and frameworks to design new interventions for implementation, adapt existing interventions with end users and settings in mind, conduct hybrid effectiveness-implementation trials, and test implementation strategies.

CONCLUSIONS

Given the prevalence and consequences of poor sleep across developmental periods, pediatric BSIs must be effective as well as adaptable, scalable, and easily disseminable. Implementation science theories, models, and frameworks can enhance access to, engagement in, and the implementation and dissemination of scalable BSIs across diverse pediatric care settings and heterogeneous populations.

Effects of Automated Diurnal Variation in Electronic Screen Temperature on Sleep Quality in Young Adults: A Randomized Controlled Trial

OBJECTIVE

Determine whether automated changes in electronic screen color temperature of personal electronic devices is associated with changes in objective and self-reported indices of sleep and mental health in young adults, as well as determine feasibility and acceptability of the experimental manipulation.

PARTICIPANTS

A single-blind randomized controlled trial was conducted at a large public university in the Pacific Northwest region of the United States. Fifty-five participants (female=78%, mean age=19.45 years) who reported using a smartphone and/or laptop computer two hours before bedtime were randomized into either an experimental group (EG; n=29) or active control group (ACG; n=26).

METHODS

Both the EG and ACG had installed on their devices a piece of software that automatically lowers the color temperature of these devices' screens as the day progresses ("f.lux"). However, only the EG had the blue-light-reducing features activated, and participants were blind to condition. Before and after the one-week long experimental manipulation period, participants completed the Pittsburgh Sleep Quality Index (PSQI), Pediatric Daytime Sleepiness Scale (PDSS), Pre-Sleep Arousal Scale (PSAS), and Patient Health Questionnaire (PHQ) and wore an actiwatch for seven consecutive nights.

RESULTS

Participants in the EG did not show greater improvement in objective sleep, self-reported sleep, or mental health compared to participants in the ACG. Participants in the EG rated the software as more distracting and purposely disabled the software more often compared to participants in the ACG.

CONCLUSIONS

Automated diurnal variation in electronic screen temperature in personal devices did not improve sleep or mental health in young adults.

Effect Evaluation of a School-Based Intervention Promoting Sleep in Adolescents: A Cluster-Randomized Controlled Trial

BACKGROUND

This study evaluated the effect of the school-based intervention Charge Your Brainzzz on adolescents' social-cognitive determinants, sleep hygiene and sleep duration and quality.

METHODS

A cluster-randomized controlled trial was conducted with 972 students from 10 Dutch high schools. Schools were randomly allocated to the intervention (N = 5) or control condition (N = 5). Outcomes were measured with the digital Consensus Sleep Diary and via a digital questionnaire, based on valid measures. Data were collected at baseline (T0), ±1.5 weeks post-intervention (T1) and ±3 months post-intervention (T2). Mixed model analyses were performed to estimate the effects on social-cognitive determinants, sleep hygiene, and sleep outcomes.

RESULTS

The intervention increased sleep knowledge post-intervention (b = 1.91; 95%CI: 1.22-2.60) and at follow up (b = 1.40; 95%CI: 0.70-2.10). The intervention was also effective in changing adolescents' attitudes (b = 0.10; 95%CI: 0.01-0.19) and perceived behavioral control (b = 0.11; 95%CI: 0.01-0.22) post-intervention. No positive changes were found regarding subjective norms, behavioral intentions, sleep hygiene, or sleep outcomes.

CONCLUSIONS

The intervention improved adolescents' sleep knowledge, attitude, and perceived behavioral control. To significantly impact sleep health, theoretically sound and systematically developed interventions are needed which take into account the interplay between sleep, sleep-related behaviors, and adolescents' social and physical environment.

Boosting Student Wellbeing Despite a Pandemic: Positive Psychology Interventions and the Impact of Sleep in the United Arab Emirates

Positive psychology interventions hold great promise as schools around the world look to increase the wellbeing of young people. To reach this aim, a program was developed to generate positive emotions, as well as improve life satisfaction, mental toughness and perceptions of school kindness in 538 expatriate students in Dubai, United Arab Emirates. Starting in September 2019, the program included a range of positive psychology interventions such as gratitude, acts of kindness and mental contrasting as examples. Life satisfaction and mental toughness at mid-year were sustained or grew by the end of the year. Positive affect, emotional wellbeing and social wellbeing increased at post-intervention 1, compared to baseline. However, this improvement reverted to baseline levels at post-intervention 2, when data were collected during the COVID-19 pandemic. Only psychological wellbeing, negative affect, perceptions of control, and school kindness were increased at post-intervention 2. During the lockdown, students moved less, but slept and scrolled more. Those who extended their sleep duration reported greater wellbeing. Boosting wellbeing through the use of positive psychology interventions works – even in a pandemic – and extended sleep duration appears to be a driving factor for this observation.

Sleep in an At Risk Adolescent Group: A Qualitative Exploration of the Perspectives, Experiences and Needs of Youth Who Have Been Excluded From Mainstream Education

The sleep needs, experiences and viewpoints were explored for UK adolescents who have been excluded from mainstream education. Qualitative data was gathered through interviews with 9 participants, aged 11-15 years, who also completed questionnaires. The participants had symptoms of inadequate sleep, poor sleep hygiene behaviours and were not getting the recommended amount of sleep on school nights. Participants described sleep patterns involving often staying up late and having different sleep timing on weekends than weekdays and having difficulties with their sleep. Use of technology and the relevance of family were identified as important and associated with facilitating and hindering factors for sleep. Participants communicated that they lack control over aspects of their sleep and their lives. The experiences and views of the participants can inform professionals' understanding of how to collaborate with adolescents to improve their sleep and highlight that continued development of sleep education programmes is timely.

Social media for students' sleep health promotion - a health intervention report during COVID -19

The COVID-19 pandemic has affected sleep health. Students' sleep health is essential for the performance of neuro-cognitive processes, as well as mental and physical balance. We assume the COVID19 pandemic has modified some sleep habits by prompting environmental and social interaction changes. In this study we surveyed a sample of 300 Brazilian students, with internet access, resident in the Federal District. They completed a questionnaire over two weeks in March 2020, i.e. the second and third week of the social isolation policy enacted in the Federal District due to COVID19. Valid responses from students aged18-24 years were analyzed. The sample was mostly female; 76,3% reported somnolence during the day, 70,2% anxiety and 87,8% worse sleep associated with stress and/or anxiety, which indicated the variables for an educational health intervention design in this context. Further, 53.2% made no effort to avoid screens before sleeping; 73.9% to avoid using the bed for work or watching television and 83.1% to avoid consuming heavy foods before sleeping. We then created an Instagram profile, @comodormimos, which focused on the main sleep issues revealed by participants in the survey. Posts on the profile were based on sleep-related subjects: sleep processes, sleep hygiene practices for students; sleep stages, function and regulation; and sleep-wake circadian rhythms. The profile gained 307 followers, mostly women (61,7%), 18-24 years old. We concluded that the Covid-10 pandemic period increased harmful sleep behavior in students. Further studies are needed to understand the impact of the COVID-19 pandemic on student sleep health.

Sleep is essential to health: an American Academy of Sleep Medicine position statement

CITATION

Sleep is a biological necessity, and insufficient sleep and untreated sleep disorders are detrimental for health, well-being, and public safety. Healthy People 2030 includes several sleep-related objectives with the goal to improve health, productivity, well-being, quality of life, and safety by helping people get enough sleep. In addition to adequate sleep duration, healthy sleep requires good quality, appropriate timing, regularity, and the absence of sleep disorders. It is the position of the American Academy of Sleep Medicine (AASM) that sleep is essential to health. There is a significant need for greater emphasis on sleep health in education, clinical practice, inpatient and long-term care, public health promotion, and the workplace. More sleep and circadian research is needed to further elucidate the importance of sleep for public health and the contributions of insufficient sleep to health disparities.

"Sleep is healthy for your body and brain." Use of student-centered photovoice to explore the translation of sleep promotion at school to sleep behavior at home

STUDY OBJECTIVES

Schools are an important setting to teach and reinforce positive health behaviors such as sleep, however, research that incorporates the student perspective of school-based sleep promotion initiatives is limited. This study explored student's perceptions of sleep behavior (how they understood and valued positive and negative sleep behaviors) and determined if and how students translate school-based sleep promotion to the home.

METHODS

Forty-five grade 4 and 5 children (aged 9-11 years) were purposefully sampled from 3 schools participating in the Alberta Project Promoting healthy Living for Everyone in schools (APPLE) in Edmonton, Canada. Using focused ethnography as the method and photovoice as a data generating strategy, qualitative in-depth information was generated through photo-taking and one-on-one interviews. Data were analyzed in an iterative, cyclical process using latent content analysis techniques.

RESULTS

Four themes related to students' perception of sleep behavior within the context of a school-based sleep promotion initiative were identified: sleep is "healthy for your body and brain," sleep habits are rooted in the home environment, school experiences shape positive sleep habits at home, and students translate sleep promotion home if they think it is useful or would be acceptable to the family.

CONCLUSION AND IMPLICATIONS

School-based sleep promotion interventions that are grounded in the comprehensive school health (CSH) approach hold promise for successfully shaping student sleep behavior. To promote health and academic success in children, future interventions should include home-school partnerships that address child sleep across multiple critical learning environments.

Sleep Characteristics in the Italian Pediatric Population: A Systematic Review

OBJECTIVE

During childhood sleep duration, quality and patterns evolve and change greatly and relate strongly to healthy development. This systematic review aims to summarize the literature on sleep characteristics in the Italian pediatric population, adopting a cultural perspective.

METHOD

Pubmed, PsycINFO and Medline databases were systematically searched. Eligible studies had to: include Italian children and adolescents; report data for one or more sleep-related variables; be published in English or Italian.

RESULTS

Twenty-nine studies were selected including 18551 Italian children or adolescents. Studies were categorized by age group: infancy and toddlerhood (0-3 years); preschool and school age (3-12 years); adolescence (12-18 years) and mixed age groups. Overall, studies showed that the Italian pediatric population present shorter sleep duration and longer sleep onset latency compared to international recommendations. Furthermore, data indicate high prevalence of dysfunctional sleep habits, such as late bed-time (all age groups), involvement of parents during bed-time (infancy and toddlerhood), and high variability between sleep times on week-days vs. weekends (adolescence). Nevertheless, most studies lacked comprehensive data on sleep patterns, focusing instead on isolated variables.

CONCLUSION

These results suggest a strong trend among Italian children and adolescents towards unhealthy sleep patterns. Comprehensive data are still lacking and large studies evaluating a broad range of sleep characteristics in Italian pediatric populations are needed. Data strongly suggest that Italian Pediatric Primary Care should place higher focus on sleep problems and implement clinical protocols directed towards improving sleep patterns in children and adolescents.

Sleep Health Promotion Interventions and Their Effectiveness: An Umbrella Review

Sleep is receiving increasing attention in public health. The aim of this umbrella review is to determine what non-pharmacological sleep health interventions have been evaluated among healthy populations, by examining target groups, settings, and effectiveness in improving sleep quality and duration. Comprehensive searches were conducted in five electronic databases (January 1975-February 2019), yielding 6505 records. Thirty-five articles were selected meeting the following eligibility criteria: (1) systematic reviews or meta-analyses of (2) sleep health interventions in (3) primarily healthy populations. Two reviewers independently screened for inclusion, extracted the data, and assessed the review quality. This umbrella review was registered with PROSPERO (CRD42019126291). Eleven intervention types were defined, and their effectiveness discussed. Substantial evidence demonstrated the effectiveness of later school start times, behavior change methods, and mind-body exercise. Other intervention types, including sleep education or relaxation techniques, demonstrated some promising impacts on sleep, but with less consistent evidence. Results were limited by high heterogeneity between studies, mixed results, and variable review quality. Nevertheless, this umbrella review is a first step towards understanding the current state of sleep health promotion and gives an overview of interventions across the lifespan.

The need for sleep and circadian education in Australian high schools: incidental results from a survey of university students

ISSUE ADDRESSED

To describe the need for high school sleep education from the perspective of undergraduate university students.

METHODS

Undergraduate students who completed an online course on sleep and circadian health were surveyed 6 months after course completion. Students were asked whether a similar course would have benefited them as high school students, and about the need for sleep education in high schools. Thematic analysis of this qualitative data was carried out.

RESULTS

Eighty-nine students who had attended 71 unique high schools provided responses. Eight-one per cent thought they would have benefitted from a similar course during high school and identified domains of sleep knowledge particularly relevant to high school students. They cited environmental barriers to healthy sleep present during high school and believed that sleep education could improve students' lifestyle, sleep and performance. Nineteen per cent of students said they would not have benefited, because they perceived sleeping patterns during high school to be nonmodifiable or believed that previous sleep education was sufficient. Of the respondents who did not think students would benefit, 53% would still tell their high school principal that there was a need for sleep education.

CONCLUSIONS

The findings support the need for engaging sleep education for high school students. Future studies should examine the perspectives of students in high school directly, rather than undergraduate students who have already shown an interest in sleep health. SO WHAT?: Sleep health is missing from the Australian school curriculum. Online courses may be an engaging method of promoting sleep and circadian health to high school students.

Update on school-based sleep education programs: how far have we come and what has Australia contributed to the field?

OBJECTIVE

School-based sleep education programs help to promote sleep health information to many children and adolescents. The aim of this systematic review was to identify and describe school-based sleep education programs, to update previous reviews and identify recent advances and improvements in this field worldwide.

METHODS

Four electronic databases were searched. Eligibility criteria included children aged 5-18 years, sleep education intervention conducted in a school setting, and at least one pre-post-measure of a sleep variable.

RESULTS

A total of 32 articles met eligibility criteria with Australian sleep researchers constituting ∼ one quarter of these studies. Studies dated from 2007 to 2020 with sample sizes ranging from 9 to 3713 students. The majority of participants were high school students and predominantly female. Education programs generally took 4-6 weeks and content was consistent across studies. Overall, exposure to sleep education increased sleep knowledge, however changes in sleep behaviour variables and secondary outcome variables (eg, mental health; cognitive function; sleep hygiene practices) presented varied results. Studies conducted since 2015 were more likely to be randomised controlled trials and to include more interactive, online designs utilising innovative content such as mindfulness.

CONCLUSIONS

An exponential growth in school sleep education programs was identified since 2016. Future studies should consider utilising objective sleep measures, longer-term follow-ups, innovative delivery methods, and stronger attempts at implementing a knowledge-to-action approach for more sustainable programs.

The Teensleep study: the effectiveness of a school-based sleep education programme at improving early adolescent sleep

Objective

To evaluate the impact of a school-based sleep education programme on adolescent sleep and sleep knowledge.

Methods

This is the first outcome report on ‘Teensleep’: a novel, teacher-led programme, comprising ten lessons that can be delivered flexibly. Students in Year 10 (n = 1504; mean age = 14.14 ± 0.35 years) from ten UK state (non-fee-paying) secondary schools received the lessons and parents received a leaflet. Effectiveness was assessed using measures across two time points (pre- and post-intervention). Students completed questionnaires on sleep knowledge, sleep quality, sleep behaviour, sleep hygiene, daytime sleepiness and health-related quality of life. A sub-sample provided objective (actigraphy, n = 84) and subjective (sleep diary, n = 74) sleep measures.

Results

Large improvements in sleep knowledge (d = 0.78), and smaller improvements in sleep quality (d = 0.15) and sleep hygiene (d = 0.11) were observed, but not in daytime sleepiness or health-related quality of life. Small and limited changes in subjective and objective sleep patterns were found. Baseline sleep quality was differentially associated with key outcomes, with those initially self-reporting poor sleep demonstrating an improvement in sleep quality, sleep hygiene and sleepiness.

Conclusion

Teensleep was effective at improving sleep knowledge but sleep changes were small. Such interventions have traditionally focused on gains for all students, but this study suggests that poor sleepers may be the most likely to experience immediate direct sleep benefits. Follow-up studies are required to investigate whether or not sleep education provides long-term benefits as a step towards preventative sleep medicine.

The impact of COVID-19 related school shutdown on sleep in adolescents: a natural experiment

Objective

During the outbreak of the COVID-19 pandemic in 2020, high schools closed or transitioned to remote teaching. The aim of this study was to describe how the COVID-19 related school shutdown impacted the sleep behaviors of typically developing adolescents.

Methods

A qualitative study was conducted between April 28 and June 3, 2020 with 45 adolescents using one-on-one semi-structured phone interviews.

Results

The “natural experiment” caused by the shutdown of schools due to the COVID-19 pandemic led to a 2-h shift in the sleep of typically developing adolescents, longer sleep duration, improved sleep quality, and less daytime sleepiness compared to those experienced under the regular school-time schedule.

Discussion

These findings are consistent with previous studies showing that delaying high school start times could be an effective way to extend sleep duration, improve sleep quality, reduce daytime sleepiness and lower adolescents' stress during the school year. As many countries look for ways to reduce the number of interactions between students in schools so that physical distancing is feasible, following teens’ delayed sleep biology could offer an affordable solution. For example, staggering arrival times by delaying school start time for older adolescents compared with younger adolescents can reduce the total number of students attending school at the same time. This strategy offers a practical means to reduce school density and the number of interactions between students which are needed to reduce the potential transmission of COVID-19 in schools, while improving adolescents sleep health.

•

Adolescents' sleep improved during the COVID19.

•

Adolescents' sleep schedule during the pandemic was 2 h later than during regular school times.

•

Delaying adolescents' school start time could help reduce transmission of COVID19.

Leveraging Technology to Improve Health in Adolescence: A Developmental Science Perspective

As technologies continue to evolve at exponential rates, online platforms are becoming an increasingly salient social context for adolescents. Adolescents are often early adopters, savvy users, and innovators of technology use. This not only creates new vulnerabilities but also presents new opportunities for positive impact-particularly, the use of technology to promote healthy learning and adaptation during developmental windows of opportunity. For example, early adolescence appears to represent a developmental inflection point in health trajectories and in technology use in ways that may be strategically targeted for prevention and intervention. The field of adolescent health can capitalize on technology use during developmental windows of opportunity to promote well-being and behavior change in the following ways: (1) through a deeper understanding of the specific ways that developmental changes create new opportunities for motivation and engagement with technologies; (2) by leveraging these insights for more effective use of technology in intervention and prevention efforts; and (3) by combining developmental science-informed targeting with broader-reach technologic approaches to health behavior change at the population level (e.g., leveraging and changing social norms). Collaboration across disciplines-including developmental science, medicine, psychology, public health, and computer science-can create compelling innovations to use digital technology to promote health in adolescents.

Afternoon School Start Times Are Associated with a Lack of Both Social Jetlag and Sleep Deprivation in Adolescents

The delayed circadian timing of adolescents creates a conflict with early school start times (SSTs). We used wrist actimetry to compare sleep parameters and routine nighttime activities in middle school students attending either a morning (0700 to 1200 h) or an afternoon (1230 to 1730 h) school shift. On school days, students from both shifts (n = 21 for morning shift, n = 20 for afternoon shift, ages 12-14 years) had a similar sleep onset, but morning-shift students had an earlier sleep offset and a 1 h 45 min shorter sleep duration than their afternoon peers, who slept the recommended 8 to 10 h of daily sleep. Only morning-shift students had afternoon naps, but this afternoon sleep was not sufficient to overcome sleep deprivation. On weekends, sleep onsets and offsets did not differ between shifts. Because only morning-shift students woke up later and slept longer (2 h 3 min) on weekends, they were also the only ones who experienced social jetlag. Daily surveys on their nighttime (from 1800 to 0600 h) activities indicated there was no difference between shifts in the time spent on leisure or using electronic media during school days, but students from both shifts spent more time in these activities during the weekend. Our study confirms that early SST in adolescents is associated with sleep deprivation and suggests that schedules that start much later than typically considered may be needed to eliminate sleep deprivation in adolescents.

The challenges of adolescent sleep

Sleep is vital for our physical, emotional and cognitive health. However, adolescents face many challenges where their sleep is concerned. This is reflected in their sleep patterns including the timing of their sleep and how much sleep they achieve on a regular basis: their sleep is characteristically delayed and short. Notably, insufficient sleep is associated with impairments in adolescent functioning. Endogenous and exogenous factors are known to affect sleep at this age. Alterations in the bioregulation of sleep, comprising the circadian timing system and the sleep/wake homeostatic system, represent the intrinsic mechanisms at work. Compounding this, environmental, psychosocial and lifestyle factors may contribute to shortened sleep. This review discusses the amount of sleep gained by adolescents and its implications, the challenges to adolescent sleep and the interventions introduced in an effort to prioritize sleep health in this important developmental period.

Prebedtime Screen Use in Adolescents: A Survey of Habits, Barriers, and Perceived Acceptability of Potential Interventions

PURPOSE

This study aimed to investigate (1) access to screens and screen use in the hour before bedtime and in bed; (2) attitudes and barriers to reducing screen time, and (3) perceptions of potential interventions to reduce screen time to benefit the sleep of New Zealand adolescents.

METHODS

Adolescents (aged 13-17 years, n = 4,811) living in New Zealand were recruited online between November 2015 and March 2016 with a direct link to complete a questionnaire about screen use in the hour before bedtime (including the types of screens used and activities) and screen use when in bed. Sleep patterns and quality were measured, and attitudes to reducing screen time using potential interventions were explored.

RESULTS

The most common prebedtime screen activities reported on most nights were social media (88%) and texting/instant messaging (77%). The majority of participants reported they used phones in bed (86%) and "agreed" they spent too much time on screens (70%), a perception that increased with age (p = .008). Being unable to communicate with friends was the most common barrier to reducing screen time (67% agreed).

CONCLUSIONS

Screen use in adolescents is complex; however, there is scope to improve sleep by reducing the impact of in-bed use of portable devices and addressing barriers to reduce screen time in adolescents.

Sleep Timing During Adolescence: A Latent Transition Analysis Approach

Objective/Background: This paper utilized a person-centered approach to examine individual differences in sleep timing cross-sectionally and prospectively in adolescents. Participants: Data from Waves 5 and 6 of the Longitudinal Study of Australian Children were used. At Wave 5, the sample included 3,552 Australian adolescents aged 12-13 years (51% males, 49% females); 84% provided data at two-year follow-up (Wave 6). Methods: Through structured interviews, adolescents provided information on sleep timing (bedtimes, sleep-onset times, and wake times) on weekends and weekdays, and relevant covariates. Latent profile analysis identified sleep profiles at Waves 5 and 6 separately; latent transition analysis examined stability and change in profiles across time. Results: Six sleep timing profiles were identified at age 12-13 years: Early Larks (n = 228; 6.4%); Larks (n = 1257; 35.4%); Intermediate (n = 1311; 36.9%); Owls (n = 351; 9.9%); Variable Owls (n = 308; 8.7%); and, Late Owls (n = 97; 2.7%). Six similar profiles were identified at age 14-15 years. The latent transition analysis indicated that the Early Larks, Larks, and Intermediate profiles were more stable over time compared with the Owls, Variable Owls, and Late Owls profiles. Higher body mass index (BMI) and longer screen time predicted transitions from Larks and Early Larks to the Owls, Variable Owls, and Late Owls profiles. Conclusions: Many adolescents showed healthy sleep timing, which continued with age. However, the Variable Owls, Owls, and Late Owls profiles reflected less healthy and more variable sleep patterns that may require targeted interventions.

Application of health behaviour theory to sleep health improvement

Although sleep hygiene is often used for broad sleep health promotion efforts, sleep hygiene education programmes are largely ineffective. These programmes are limited by their lack of a theoretical foundation. Health behaviour theory (HBT) has been used for decades to successfully predict and modify many health behaviours, but its use in the study of sleep health is rare. The purpose of this review is threefold. First, four dominant HBTs will be introduced. Second, the brief literature on HBT and sleep health will be reviewed. Lastly, a translational research agenda will be proposed. The present review concludes that HBT shows potential in both the prediction and modification of sleep health, and that there are several short- and long- term research goals to advance these efforts.

Challenges in implementing and assessing outcomes of school start time change in the UK: experience of the Oxford Teensleep study

OBJECTIVE

Later school start times for adolescents have been implemented in the US and associated benefits found, although no randomised controlled trials (RCT) have been undertaken. The objective of this study was to evaluate the impact of two school interventions in the UK, a delayed start time and a sleep education programme, on students' academic performance, sleep outcomes and health-related quality of life.

METHODS

The study had an RCT design to enable an investigation into the differential effects of two interventions or a combination of both: schools were to delay their start time to 10:00am and/or provide a classroom-based sleep education programme. The recruitment target was 100 state (non-fee-paying) secondary schools. Participants were to be students in Year 10/11 (14-16-year-olds).

RESULTS

Despite much media coverage, only two schools volunteered to take part in the RCT. The main challenges faced in recruitment fell under three categories: research design, school, and project-specific issues. The delayed start time and prospect of randomisation to this intervention were the overwhelming reasons cited for not taking part. Facilitators and barriers to research were identified. Recommendations include carrying out a feasibility study prior to a main trial, allowing adequate time for recruitment, involving stakeholders throughout the decision-making process, incorporating independent (fee-paying) schools in recruitment, focusing on students not taking important examinations or involving an older year group with greater independence.

CONCLUSION

The Teensleep study provides supporting evidence that evaluating the effects of a change in school start times through an RCT is unfeasible in the UK.

The 8-Hour Challenge: Incentivizing Sleep during End-of-Term Assessments

Sleep is critical to physical health, mental well-being, attention, and creativity. During the week of final exams, however, fewer than 10% of undergraduate students maintain the recommended average of 8 hours/night (or, even the recommended minimum of 7 hours/night). For students completing multifaceted projects in studio-based majors (e.g., interior design, architecture, graphic design, studio art), anecdotal and questionnaire data suggest that the end-of-semester reduction in sleep duration may be even worse. One potential solution is to offer students an incentive to maintain healthy sleep durations. We offered interior design students, who were enrolled in a freshman-level graphics studio course, an optional extra credit incentive to maintain optimal sleep durations for five nights leading up to the due date of their final project. If participants maintained an average sleep duration of ≥ 8.0 hours for five nights, they would earn extra credit. By contrast, if they slept an average of 7.0-7.9 hours, there would be no grade change, and if they slept an average of ≤ 6.9 hours, they were instructed that they would lose points (no points were actually deducted). Of the 28 students enrolled in the course, 22 students attempted the challenge (78.6%), and we monitored their sleep duration objectively using wristband actigraphy devices. We compared their sleep duration to that of a group of 22 non-incentivized students enrolled in the same program. In the non-incentivized comparison group, very few students averaged 8 hours (9%) or even 7 hours (14%) of sleep per night. In dramatic contrast, the eight-hour challenge increased the percentage of 8-hour and 7-hour sleepers to 59% and 86%, respectively. Participants who took the eight-hour challenge slept an average of 98 minutes more each night than non-incentivized students and 82 minutes more than they self-reported to sleeping during the semester. The substantial increase in nightly sleep duration did not come at a cost to project performance. Individuals who opted in to the sleep challenge performed as well on the final project as students who did not opt in, and students who showed more consistent sleep (i.e., fewer nights of poor sleep followed by rebound sleep) performed better than students who showed inconsistent sleep. Thus, even during highly stressful "deadline" weeks, students can maintain healthy sleeping patterns without exacting a cost on their project performance.

Effects of a Workplace-Based Sleep Health Program on Sleep in Members of the German Armed Forces

STUDY OBJECTIVES

To develop and evaluate a brief manual-based sleep health program within the workplace health promotion of the German Armed Forces.

METHODS

The sleep health program comprised four weekly group sessions. Sixty-three members (48 males) were randomly allocated to either a treatment group or a waiting control group matching for age, sex, and baseline Pittsburgh Sleep Quality Index (PSQI). The control group had to wait before participating in the sleep health program until the treatment group finished the intervention. Sleep was assessed by ambulatory polysomnography (PSG) as well as with evening and morning protocols at baseline (t0), directly after the treatment group participated in the sleep health program (t1), and after the control group finished participation (t2). The PSQI, the Insomnia Severity Index (ISI), and the Epworth Sleepiness Scale (ESS) were applied at the same three time points, and during a 3-month follow-up evaluation (t3).

RESULTS

Fifty-seven out of the 63 randomized individuals (42 males, mean age = 40.6 years; complete PSG data: n = 36; complete questionnaire data: n = 39) participated in the sleep health program. Objective wake after sleep onset, sleep efficiency, latency to persistent sleep, self-reported sleep latency, restfulness, PSQI, and ISI scores improved with medium or large effects in both groups. ESS scores decreased with moderate effects in the treatment group only.

CONCLUSIONS

The sleep health program had a positive and stable effect on objective and self-reported sleep parameters, and it is suitable as a preventive measure in members of the German Armed Forces.

Assessment and treatment of pediatric behavioral sleep disorders in Canada

OBJECTIVES/BACKGROUND

This paper outlines the current state of Canadian training, clinical services, research, and advocacy initiatives related to non-respiratory sleep disorders, with a specific focus on insomnia, the most common sleep problem in children.

METHODS

Information for this narrative review was collected from peer-reviewed publications, web-resources, and personal communications and experiences.

RESULTS

It is estimated that approximately one-third of Canadian children and youth present with insomnia, and that this is impacting their physical and mental health, as well as learning in school. Training in pediatric sleep is limited and highly inconsistent within and across disciplines. While there are some publicly and privately funded pediatric sleep services available, these are mostly focused on respiratory sleep problems and are not equally accessible across the country.

CONCLUSIONS

Pediatric assessment and treatment services for non-respiratory sleep disorders needs to be more integrated into the Canadian health care system.

Who benefits from adolescent sleep interventions? Moderators of treatment efficacy in a randomized controlled trial of a cognitive-behavioral and mindfulness-based group sleep intervention for at-risk adolescents

BACKGROUND

The aim of this study was to test moderators of therapeutic improvement in an adolescent cognitive-behavioral and mindfulness-based group sleep intervention. Specifically, we examined whether the effects of the program on postintervention sleep outcomes were dependent on participant gender and/or measures of sleep duration, anxiety, depression, and self-efficacy prior to the interventions.

METHOD

Secondary analysis of a randomized controlled trial conducted with 123 adolescent participants (female = 59.34%; mean age = 14.48 years, range 12.04-16.31 years) who had elevated levels of sleep problems and anxiety symptoms. Participants were randomized into either a group sleep improvement intervention (n = 63) or group active control 'study skills' intervention (n = 60). The sleep intervention ('Sleep SENSE') was cognitive behavioral in approach, incorporating sleep education, sleep hygiene, stimulus control, and cognitive restructuring, but also had added anxiety-reducing, mindfulness, and motivational interviewing elements. Components of the active control intervention ('Study SENSE') included personal organization, persuasive writing, critical reading, referencing, memorization, and note taking. Participants completed the Pittsburgh Sleep Quality Index (PSQI), Spence Children's Anxiety Scale (SCAS), Center for Epidemiologic Studies Depression Scale (CES-D), and General Self-Efficacy Scale (GSE) and wore an actigraph and completed a sleep diary for five school nights prior to the interventions. Sleep assessments were repeated at postintervention. The trial is registered with the Australian New Zealand Clinical Trials Registry (ACTRN12612001177842; http://www.anzctr.org.au/TrialSearch.aspx?searchTxt=ACTRN12612001177842&isBasic=True).

RESULTS

The results showed that compared with the active control intervention, the effect of the sleep intervention on self-reported sleep quality (PSQI global score) at postintervention was statistically significant among adolescents with relatively moderate to high SCAS, CES-D, and GSE prior to the intervention, but not among adolescents with relatively low SCAS, CES-D, and GSE prior to the intervention. The results were consistent across genders. However, the effects of the sleep intervention on actigraphy-measured sleep onset latency and sleep diary-measured sleep efficiency at postintervention were not dependent on actigraphy-measured total sleep time, SCAS, CES-D, or GSE prior to the intervention.

CONCLUSIONS

This study provides evidence that some sleep benefits of adolescent cognitive-behavioral sleep interventions are greatest among those with higher levels of anxiety and depressive symptoms, suggesting that this may be an especially propitious group to whom intervention efforts could be targeted. Furthermore, adolescents with lower levels of self-efficacy may need further targeted support (e.g. additional motivational interviewing) to help them reach treatment goals.

Mechanisms underlying the association between insomnia, anxiety, and depression in adolescence: Implications for behavioral sleep interventions

There is robust evidence of an association between insomnia, anxiety, and depression in adolescence. The aim of this review is to describe and synthesize potential mechanisms underlying this association and explore implications for the design of adolescent behavioral sleep interventions. Specifically, we examine whether insomnia symptoms are a mechanism for the development of internalizing symptoms in adolescence and whether sleep interventions are an effective treatment for both insomnia and internalizing symptoms in adolescence because they target the shared mechanisms underlying these disorders. Research using different methodologies points to the role of sequential, parallel, and interacting mechanisms. In this paper, we review a wide range of relevant biological (i.e., polymorphisms and dysregulation in serotonin, dopamine, and circadian clock genes; alterations in corticolimbic and mesolimbic brain circuits; cortisol reactivity to stress; inflammatory cytokine dysregulation; biased memory consolidation; changes in sleep architecture), psychological (i.e., cognitive inflexibility, interpretational biases, judgment biases, negative attribution styles, worry, rumination, biased attention to threat, dysfunctional beliefs and attitudes about sleep, misperception of sleep deficit), and social mechanisms (i.e., reduced and impaired social interactions, unhelpful parenting behaviors, family stress) and propose an integrative multilevel model of how these phenomena may interact to increase vulnerability to both insomnia and internalizing disorders. Several 'biopsychosocial' mechanisms hold promise as viable treatment targets for adolescent behavioral sleep interventions, which may reduce both insomnia and internalizing symptoms.

Modified Children's sleep habits questionnaire for behavioral sleep problems: A validation study

OBJECTIVES

Behavioral sleep problems (BSPs) are prevalent and consequential in young children. There is a need for screening tools that identify BSPs-which are often rooted in the parent-young child relationship-and typically respond to behavior management. Such a tool would increase capacity to identify and treat BSPs. We sought to validate a short-form version of the widely used Children's Sleep Habits Questionnaire (SF-CSHQ) that omitted items that would not be responsive to behavioral strategies.

METHODS

The original 33-item CSHQ elicits parent report of "behaviorally-based" and "medically-based" sleep items (eg, parasomnias and sleep disordered breathing). We conducted analyses to develop a SF-CSHQ that excludes its "medically-based" items, to determine (a) the SF-CSHQ threshold score corresponding to the full CSHQ clinical cut-off score (≥41), and (b) preliminary validity of this SF-CSHQ. Data were re-analyzed from the original data that established the CSHQ's psychometric properties in 4-10 year olds, and a second dataset that established its validity in 24-66 month olds.

RESULTS

In both datasets, a threshold score of 30 had correlations of 0.90-0.94 with the original cut-off. This 23-item SF-CSHQ cut-off functioned as well as the full CSHQ cut-off in discriminating between children with vs without a parent-reported behavioral sleep problem, and with vs without prolonged sleep latency (per actigraphy).

CONCLUSION

We established preliminary validity of modified version of the widely-used CSHQ. This SF-CSHQ may be useful for widening screening and first-line guidance for behavioral sleep problems in young children, among professionals who are not sleep medicine specialists.
