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

Subtyping at-risk adolescents for predicting response toward insomnia prevention program

BACKGROUND

Previous study has shown that a brief cognitive-behavioral prevention insomnia program could reduce 71% risk of developing insomnia among at-risk adolescents. This study aimed to evaluate the differential response to insomnia prevention in subgroups of at-risk adolescents.

METHODS

Adolescents with a family history of insomnia and subthreshold insomnia symptoms were randomly assigned to a 4-week insomnia prevention program or nonactive control group. Assessments were conducted at baseline, 1 week, and 6- and 12-month after the intervention. Baseline sleep, daytime, and mood profiles were used to determine different subgroups by using latent class analysis (LCA). Analyses were conducted based on the intention-to-treat approach.

RESULTS

LCA identified three subgroups: (a) insomnia symptoms only, (b) insomnia symptoms with daytime sleepiness and mild anxiety, and (c) insomnia symptoms with daytime sleepiness, mild anxiety, and depression. The incidence rate of insomnia disorder over the 12-month follow-up was significantly reduced for adolescents receiving intervention in subgroup 3 compared with the controls (hazard ratio [HR] = 0.37; 95% confidence interval [CI]: 0.13-0.99; p = .049) and marginally for subgroup 2 (HR = 0.14; 95% CI: 0.02-1.08; p = .059). In addition, adolescents who received intervention in subgroups 2 and 3 had a reduced risk of excessive daytime sleepiness (subgroup 2: adjusted OR [AdjOR] = 0.45, 95% CI: 0.23-0.87; subgroup 3: AdjOR = 0.32, 95% CI: 0.13-0.76) and possible anxiety (subgroup 2: AdjOR = 0.47, 95% CI: 0.27-0.82; subgroup 3: AdjOR = 0.33, 95% CI: 0.14-0.78) compared with the controls over the 12-month follow-up.

CONCLUSIONS

Adolescents at risk for insomnia can be classified into different subgroups according to their psychological profiles, which were associated with differential responses to the insomnia prevention program. These findings indicate the need for further phenotyping and subgrouping at-risk adolescents to develop personalized insomnia prevention.

Randomised Controlled Trial of a Behavioural Sleep Intervention, 'Sleeping Sound', for Autistic Children: 12-Month Outcomes and Moderators of Treatment

This study examined the sustained and moderating effects of a behavioural sleep intervention for autistic children in a randomised controlled trial. Autistic children (5-13 years) with sleep problems were randomised to the Sleeping Sound intervention or Treatment as Usual (TAU). At 12-month follow-up (n = 150), caregivers of children in the Sleeping Sound group reported greater reduction in child sleep problems compared to TAU (p < .001, effect size: - 0.4). The long-term benefits of the intervention were greater for children taking sleep medication, children of parents who were not experiencing psychological distress, and children with greater autism severity. The Sleeping Sound intervention demonstrated sustained improvements in child sleep. Identified moderators may inform treatment by indicating which subgroups may benefit from further support.

Focus Groups to Inform User-Centered Development of an eHealth Sleep Intervention for Adolescents: Perspectives of Youth with Insomnia Symptoms, with and without Pain

INTRODUCTION

Adolescence is a developmental stage that often coincides with increasing sleep problems. Focus groups were conducted to inform development of an adolescent eHealth sleep intervention by exploring opinions about (1) healthy sleep practices, and (2) using an eHealth intervention.

METHODS

Adolescents 14-18 years old experiencing symptoms of insomnia based on the Insomnia Sleep Index, with and without recurrent pain, and associated stakeholders (i.e., parents, school personnel, and health care providers) were recruited. Across six online focus groups, 24 adolescents with insomnia participated (14 pain-free, 10 with recurrent pain; 10 male, 14 female). Across seven online focus groups, 22 stakeholders participated, including 8 parents, 9 school professionals, and 5 health care providers (10 male, 8 female). Using a content analysis, subthemes were induced from transcripts.

RESULTS

Most healthy sleep practices were perceived as reasonable for adolescents to implement, except avoiding technology before bed and using bedrooms only for sleep. Three primary barriers to sleep practices were identified, including a variable schedule due to lifestyle factors, technology at night, and academics interfering with sleep, and only in the pain group, the barrier related to pain was identified. Content addressing adolescent-specific barriers was considered important to include in a sleep intervention. Desirable eHealth components included interactive features, videos, audio, and pictures to present information. A common barrier to using an eHealth sleep intervention was the program feeling too academic, with accessibility of the sleep information and strategies as a common facilitator.

CONCLUSIONS

This research represents the first step in a user-centered approach to developing an adolescent eHealth sleep intervention. These results provide insights from a range of perspectives on guiding adolescents to follow healthy sleep practices. Next, these findings will be integrated in the development of an eHealth intervention for adolescents with and without recurrent pain.

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.

Insomnia in Infancy, Childhood, and Adolescence

Insomnia is the most prevalent sleep disorder in youth, tends to persist over time, and is associated with a myriad of adverse outcomes. This paper synthesizes the current evidence regarding the phenomenology, prevalence, assessment, consequences, cause, and treatment of pediatric insomnia, highlighting areas that warrant further research and addressing the unique characteristics of this disorder in infants, children, and adolescents.

Novel digital methods for gathering intensive time series data in mental health research: scoping review of a rapidly evolving field

Recent technological advances enable the collection of intensive longitudinal data. This scoping review aimed to provide an overview of methods for collecting intensive time series data in mental health research as well as basic principles, current applications, target constructs, and statistical methods for this type of data.In January 2021, the database MEDLINE was searched. Original articles were identified that (1) used active or passive data collection methods to gather intensive longitudinal data in daily life, (2) had a minimum sample size of N ⩾ 100 participants, and (3) included individuals with subclinical or clinical mental health problems.In total, 3799 original articles were identified, of which 174 met inclusion criteria. The most widely used methods were diary techniques (e.g. Experience Sampling Methodology), various types of sensors (e.g. accelerometer), and app usage data. Target constructs included affect, various symptom domains, cognitive processes, sleep, dysfunctional behaviour, physical activity, and social media use. There was strong evidence on feasibility of, and high compliance with, active and passive data collection methods in diverse clinical settings and groups. Study designs, sampling schedules, and measures varied considerably across studies, limiting the generalisability of findings.Gathering intensive longitudinal data has significant potential to advance mental health research. However, more methodological research is required to establish and meet critical quality standards in this rapidly evolving field. Advanced approaches such as digital phenotyping, ecological momentary interventions, and machine-learning methods will be required to efficiently use intensive longitudinal data and deliver personalised digital interventions and services for improving public mental health.

Mind-Body Integrative Health (MBIH) Interventions for Sleep among Adolescents: A Scoping Review of Implementation, Participation and Outcomes

Adolescents get insufficient sleep, adversely affecting health. Mind-body integrative health interventions for adolescents have been shown to reduce stress, a barrier to good sleep. This scoping review aimed to synthesize mind-body integrative health interventions for adolescents, how interventions were implemented, who was reached. A systematic search of four online databases was conducted. Randomized, quasi-experimental, and single-group designs with participants ages 10-24 years were included. Twelve studies covering 10 interventions using mindfulness, qigong, aromatherapy, or yoga were identified. Participants were predominantly female; only one study reported participants' race or ethnicity (81% non-Hispanic white). Most (n=6) interventions were delivered in groups, and half reported significant improvements in subjective sleep quality. Mindfulness-based stress reduction and mindfulness-based cognitive therapy were the most commonly used modalities, with reported impact on sleep outcomes measured objectively. The two interventions that found statistically significant, moderate improvements in objectively-measured sleep onset latency and sleep efficiency were of higher intensity and used mindfulness. Four interventions were self-directed; participants in these struggled with adherence; significant impacts on sleep were not found. While findings were mixed, stemming in part from the quality of the underlying studies, this review identified several promising features of interventions, including using mindfulness, ensuring sufficient intervention dose, and targeting interventions towards adolescents with poor sleep at baseline (rather than a general population of adolescents). The findings suggests that sleep interventions for adolescents may improve psychological well-being as an intermediate effect, as sleep improvements were observed mostly among participants with poor sleep quality or anxiety symptoms at baseline. This review identified several gaps in the literature. Despite documented racial and ethnic disparities in sleep quality among adolescents, published evidence of mind-body integrative health-based sleep interventions among Black and Latinx adolescents is lacking. None of the studies in this review assessed developmental stage or age differences, despite documented differences in sleep across age groups of adolescents. These two gaps in the evidence should be addressed in future intervention research.

Cognitive Behavioral Therapy for Insomnia in School-Aged Children and Adolescents

One of the most prevalent sleep disorders in children and adolescents is "insomnia," which can be briefly described as problems with initiating and/or maintaining sleep with associated daytime consequences. These are typical insomnia symptoms, and when experienced for long enough and when they interfere with an important area of the young person's life (eg, schooling), then a diagnosis of an insomnia disorder may be warranted. The authors strongly urge the scientific community to conduct further controlled trials, including dismantling trials that evaluate the relative effectiveness of individual cognitive behavioral therapy for insomnia components.

Sleep to Internalizing Pathway in Young Adolescents (SIPYA): A proposed neurodevelopmental model

The prevalence of internalizing disorders, i.e., anxiety and depressive disorders, spikes in adolescence and has been increasing amongst adolescents despite the existence of evidence-based treatments, highlighting the need for advancing theories on how internalizing disorders emerge. The current review presents a theoretical model, called the Sleep to Internalizing Pathway in Young Adolescents (SIPYA) Model, to explain how risk factors, namely sleep-related problems (SRPs), are prospectively associated with internalizing disorders in adolescence. Specifically, SRPs during late childhood and early adolescence, around the initiation of pubertal development, contribute to the interruption of intrinsic brain networks dynamics, both within the default mode network and between the default mode network and other networks in the brain. This interruption leaves adolescents vulnerable to repetitive negative thought, such as worry or rumination, which then increases vulnerability to internalizing symptoms and disorders later in adolescence. Sleep-related behaviors are observable, modifiable, low-stigma, and beneficial beyond treating internalizing psychopathology, highlighting the intervention potential associated with understanding the neurodevelopmental impact of SRPs around the transition to adolescence. This review details support for the SIPYA Model, as well as gaps in the literature and future directions.

Effects of an internet-delivered insomnia intervention for older adults: A secondary analysis on symptoms of depression and anxiety

Objective

To test whether an Internet-delivered cognitive behavioral therapy for insomnia (CBT-I) program for older adults attenuates symptoms of depression and anxiety.

Methods

Adults aged ≥ 55 with insomnia were randomized to SHUTi-OASIS (Sleep Healthy Using the Internet for Older Adult Sufferers of Insomnia and Sleeplessness; N = 207) or Patient Education (PE; N = 104). Depression and anxiety were assessed (HADS-D and HADS-A, respectively) at baseline, post-assessment, and 6- and 12-month follow-ups.

Results

Multilevel modeling of HADS-D showed a condition by time interaction (F[3,779] = 3.23, p = .02): SHUTi-OASIS participants reported lower symptoms than PE at post-assessment. There was no such interaction effect for HADS-A (F[3,779] = 2.12, p = .10). Generalized linear modeling showed no moderation of effects by baseline symptom severity.

Conclusions

Participants randomized to Internet-delivered CBT-I showed stable depression and anxiety across time, while control participants’ depressive symptoms briefly increased. CBT-I may help prevent development or worsening of psychological distress among older adults with insomnia.

Sleep disturbances, circadian activity, and nocturnal light exposure characterize high risk for and current depression in adolescence

Study Objectives

Major depressive disorder (MDD) in adolescence is associated with irregularities in circadian rhythms and sleep. The characterization of such impairment may be critical to design effective interventions to prevent development of depression among adolescents. This study aimed to examine self-reported and actimetry-based circadian rhythms and sleep–wake behavior associated with current MDD and high risk (HR) for MDD among adolescents.

Methods

Ninety-six adolescents who took part in the IDEA-RiSCo study were recruited using an empirically developed depression-risk stratification method: 26 classified as low risk (LR), 31 as HR, and 39 as a current depressive episode (MDD). We collected self-report data on insomnia, chronotype, sleep schedule, sleep hygiene as well as objective data on sleep, rest-activity, and light exposure rhythms using actimetry for 10 days.

Results

Adolescents with MDD exhibited more severe insomnia, shorter sleep duration, higher social jetlag (SJL), lower relative amplitude (RA) of activity, and higher exposure to artificial light at night (ALAN) compared with the other groups. They also presented poorer sleep hygiene compared with the LR group. The HR group also showed higher insomnia, lower RA, higher exposure to ALAN, and higher SJL compared with the LR group.

Conclusions

HR adolescents shared sleep and rhythm alterations with the MDD group, which may constitute early signs of depression, suggesting that preventive strategies targeting sleep should be examined in future studies. Furthermore, we highlight that actimetry-based parameters of motor activity (particularly RA) and light exposure are promising constructs to be explored as tools for assessment of depression in adolescence.

Predictors of Sleep-Problem Trajectories Across Adolescence

Stress and sleep problems are significantly correlated in adolescents. Few longitudinal studies, however, have evaluated possible correlates and predictors of sleep problems at multiple points across adolescence. The current study examined the relation between stress and sleep problems across four years in a sample of adolescents who varied in risk for psychopathology. Participants included 223 adolescents (55% female) and 223 mothers (77% with a history of a mood disorder during their child's life). Youth were evaluated in grade 7 (M = 12.69 years, SD = 0.61) and again in grades 8, 9, and 11. Sleep problems were assessed as part of a clinical interview, and weekly stressful events were measured with the Life Events Interview for Adolescents. Multi-group latent growth curve analyses were conducted. Among youth whose mothers had a history of depression (high-risk), sleep problems significantly increased over time (p < .001). Second, among high-risk youth, at each time point, higher stress levels during the prior three months significantly predicted higher levels of sleep problems (p < .001). Finally, across the entire sample, at each time point a greater level of sleep problems predicted higher stress ratings a year later (p ≤ .001). Thus, stress was a significant predictor of sleep problems across multiple years of adolescence, particularly among offspring of mothers with a history of depression. Results highlight targets for preventive interventions for sleep problems in youth.

Impact of a Behavioral Sleep Intervention in Adolescents With ADHD: Feasibility, Acceptability, and Preliminary Effectiveness From a Pilot Open Trial

OBJECTIVE

An open trial tested the feasibility, acceptability, and preliminary effectiveness of a behavioral sleep intervention in adolescents with ADHD.

METHOD

Fourteen adolescents (ages 13-17 years; 50% male) with ADHD and co-occurring sleep problems received the cognitive-behavioral-based Transdiagnostic Sleep and Circadian Intervention for Youth (TranS-C). Adolescent, parent, and teacher ratings, actigraphy, and daily sleep diaries were collected at pre-intervention, post-intervention, and 3-month follow-up.

RESULTS

Adolescents experienced moderate to large improvements in sleep, mental health symptoms, and daily life executive functioning from pre-treatment to post-treatment, and improvements were generally maintained at 3 months. Pre-intervention, 71.4% of adolescents were classified as poor sleepers and this was reduced to 21.4% and 28.6% at post-treatment and follow-up, respectively.

CONCLUSION

This study provides strong preliminary evidence that TranS-C improves sleep and associated outcomes in adolescents with ADHD and co-occurring sleep problems. A randomized controlled trial is needed to rigorously test the efficacy of TranS-C in this population.

Moderators of Cognitive Behavioral Treatment for Insomnia on Depression and Anxiety Outcomes

PURPOSE OF REVIEW

With a focus on reviewing adequately powered randomized controlled trials, we present recent research on the potential of cognitive behavioral therapy for insomnia (CBT-I) to improve depression and anxiety outcomes among patients with insomnia and one of the following comorbid psychiatric disorders: major depressive disorder (MDD), generalized anxiety disorder (GAD), or posttraumatic stress disorder (PTSD). We also examine potential moderators of CBT-I on depression and anxiety outcomes in this population.

RECENT FINDINGS

Despite high comorbidity rates, current behavioral and pharmacological treatments for MDD, GAD, and PTSD do not substantially target or improve insomnia symptoms; residual insomnia is exceedingly common even among patients who experience remission. Insomnia plays a critical role in the onset and maintenance of depression and anxiety, and treating insomnia with CBT-I may improve global outcomes for patients with MDD, GAD, and PTSD. CBT-I is superior to traditional depression/anxiety treatment in improving insomnia symptoms among patients with comorbid psychiatric disorders. Results are mixed on whether CBT-I (either alone or augmented with depression/anxiety treatment) is effective in improving overall MDD, GAD, and PTSD outcomes. Evening circadian preference and depression/anxiety symptom severity may moderate the effect of CBT-I on depression and anxiety outcomes.

Effectiveness of a Mindfulness-Based Group Intervention for Chinese University Students with Sleep Problems

The increasing prevalence of sleep disorders among university students should be taken seriously. Group counseling involving a mindfulness-based strategy may help prevent students from developing insomnia and subsequent mental health disorders. This study aimed to evaluate the ameliorating effects of a mindfulness-based group intervention on sleep problems and emotional symptoms in university students in China. Twenty-one university students (16 females, 22.71 ± 4.28 years) who were not on medication were recruited and assigned to the intervention group based on the criterion of high levels of sleep problems. Additionally, twenty-four university students (19 females, 24.50 ± 0.93 years) were included as a nonrandomized control group. Individuals in the intervention group participated in a two-hour group intervention once a week for eight sessions. All participants completed self-reported questionnaire baseline tests, postintervention tests, and one-month follow-ups on mindfulness, sleep quality, anxiety and depressive symptoms. Repeated-measures ANOVA was performed. The results revealed significant intervention effects, with significant differences observed between the two groups in mindfulness and sleep quality. However, there was no significant effect of the intervention on anxiety and depressive symptoms. This study contributes to a better understanding of the effectiveness of mindfulness-based intervention in addressing sleep problems in university students.

Associations Between Multiple Health-Promoting Behaviors and Subjective Well-Being in High School Age Youth

BACKGROUND

Conceptualizations of health have expanded to include indicators of adolescents' physical and mental wellness, rather than solely the absence of diseases or disorders. Although extensive research has identified links between mental and physical wellness, few studies have investigated the relationship between health promotion and happiness, particularly in adolescent populations who may be at particular risk for engaging in health-compromising behaviors, such as alcohol consumption.

METHODS

This cross-sectional study examined the relationship between 12 health-promoting behaviors and subjective well-being in a sample of 450 high school students from 2 states. Participants reported on their diet, physical activity, sleep hygiene habits, as well as abstinence from tobacco and alcohol products, and completed a multidimensional assessment of subjective well-being.

RESULTS

Findings demonstrated that 7 of the 12 health-promoting behaviors were significantly correlated with adolescents' subjective well-being. A sizeable portion of the variance in adolescents' subjective well-being (39.8%) was accounted for by the linear combination of the 12 health-promoting behaviors of interest. Increased physical activity, sleep hygiene cognitive/emotional factors, and bedtime routine all were identified as unique predictors of subjective well-being.

CONCLUSIONS

These findings bring attention to the salience of daily physical activity and sleep hygiene and their associations with adolescents' happiness.

Examining 24-Hour Activity and Sleep Behaviors and Related Determinants in Latino Adolescents and Young Adults With Obesity

Background. Few studies have examined 24-hour activity and sleep behaviors and their contribution to type 2 diabetes (T2D) in Latino adolescents and young adults with obesity. Aim. This study included quantitative data on T2D risk and 24-hour activity and sleep behaviors and qualitative data on individual, social, and environmental behavioral determinants. Method. A 7 day, 24-hour, wrist-worn accelerometer protocol assessed moderate-to-vigorous physical activity (PA), sedentary behaviors (SB), sleep, and sleep regularity, in adolescents (N = 38; 12-16 years) and young adults (N = 22; 18-22 years). T2D-related outcomes included adiposity (BMI, BF%, waist circumference), fasting, and 2-hour glucose. A subsample of participants (N = 16 adolescents, N = 15 young adults) completed interviews to identify behavioral determinants. Results. High levels of PA were observed among adolescents (M = 103.8 ± 67.5 minutes/day) and young adults (M = 96.8 ± 78.8 minutes/day) as well as high levels of SB across both age groups (≥10 hours/day). Sleep regularity was negatively associated with adiposity (all ps < .05) in both age groups as well as fasting and 2-hour glucose in young adults (all ps < .05). Social support was associated with PA in both age groups as well as SB in younger youth. Auditory noises, lights, and safety inhibited sleep in both age groups. Conclusion. PA is critical for disease reduction, yet reducing SB and improving sleep are also important targets for reducing T2D risk in Hispanic adolescents and young adults. Future health promotion and disease prevention strategies should leverage qualitative findings regarding behavioral determinants.

[Sleep behavior and problems in children and adolescents of a psychiatric day clinic sample: results and requirements for systematic diagnostic]

Sleep behavior and problems in children and adolescents of a psychiatric day clinic sample: results and requirements for systematic diagnostic Abstract. Sleep disorders are common in adults as well as children and adolescents. Children and adolescents in psychiatric treatment (CAP) are especially affected by sleep problems. Cognitive behavioral therapy represents the first-line treatment, preceded by a standardized procedure for sleep diagnostics. To date, no study has investigated sleep behavior in CAP day clinics in Germany. In this study, N = 46 children/adolescents receiving CAP treatment in a day clinic completed a sleep diary (7 days) and a sleep anamnesis scheme with the help of their parents, and their sleep behavior was assessed by a clinician. Furthermore, a parent- and a self-report questionnaire plus a clinical assessment of the mental disorders in the children/adolescents were collected. 52 % of the children/ adolescents exhibited sleep disorders or sleep abnormalities (= sleep disorder symptoms in the context of comorbid disorders), in particular problems falling asleep or to falling asleep and sleeping through the night (26 %). In addition, 33 % reported having nightmares. Their sleep behavior correlated significantly with their external behavior problems (r = .38 .61, p = .02-.04); their sex (female: p = .01-≤ .001, |d| = 1.57-2.50) and their age (older: p = .05, |d| = .78) also significantly influenced sleep behavior. Particularly external behavior problems were associated with sleep problems in this day-care population. In summary, a multi-method-multi-informant procedure should be established for the systematic diagnostics of sleep abnormalities, together with individualized cognitive-behavioral therapy of sleep problems, especially in patients with external behavior problems.

The ratio of morning cortisol to CRP prospectively predicts first-onset depression in at-risk adolescents

RATIONALE

Early-onset adolescent depression is related to poor prognosis and a range of psychiatric and medical comorbidities later in life, making the identification of a priori risk factors for depression highly important. Increasingly, dysregulated levels of immune and neuroendocrine markers, such as C-reactive protein (CRP) and cortisol, have been demonstrated as both precursors to and consequences of depression. However, longitudinal research with adolescent populations is limited and demonstrates mixed immuno-endocrine-depression links.

OBJECTIVE

This study explored the putative bidirectional relationship between salivary measures of cortisol (Cort) and CRP, including the novel Cort:CRP ratio and depression.

METHODS

Participants from the randomized control trial 'Sleep and Education: learning New Skills Early' (SENSE) Study were 122 adolescents at risk for depression (73 females) aged 12-16 years (M = 12.71 years, SD = 1.01 years) assessed at baseline (T1), post-intervention (T2), and a two-year follow-up (T3).

RESULTS

Logistic regression results demonstrated that adolescents with higher T1 Cort:CRP_morn ratio levels were two-fold more likely to develop a first-onset depressive disorder from T2 to T3 as compared to adolescents with lower Cort:CRP_morn ratio levels, β = 0.73, t (36) = 2.15, p = .04, OR = 2.08. This effect was not moderated by treatment condition (β = -1.38, t (13) = -1.33, p = .20) and did not change when controlling for known risk factors for depression, including sex, age, body-mass index, socio-economic status, T1 anxiety disorder, nor T1 sleep disturbance, anxiety, or depressive symptoms (β = 0.91, t (31) = 2.14, p = .04).

CONCLUSION

Results highlight potential immuno-endocrine dysregulation as an underlying risk factor for adolescent first-onset depression, and may inform the development of targeted, preventative biobehavioral treatment strategies for youth depression.

Stress, Sleep, and Coping Self-Efficacy in Adolescents

Adults are thought to show a sleep-stress spiral in which greater stress worsens sleep quality, which amplifies stress, which leads to worse sleep. This study examined whether adolescents show a similar spiral, and if so, whether coping self-efficacy-believing one can cope with stress-interrupts the spiral. Temporal dynamics of perceived stress, sleep quality, and coping self-efficacy were tracked in 381 9th graders (49% female, mean age 14.43, age range 14-16) using daily surveys across two school weeks (3184 observations). Though expected associations were evident between individuals, only a unidirectional path was found within individuals from sleep quality to perceived stress via coping self-efficacy. This challenges the conventional bidirectional understanding of sleep-stress relations and suggests coping self-efficacy as an intervention target.

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.

Co-Sleeping between Adolescents and Their Pets May Not Impact Sleep Quality

Pet–owner co-sleeping is increasingly common in some parts of the world. Adult owners often subjectively report benefits of co-sleeping with pets, although objective actigraphy reports conversely indicate sleep disruptions due to the pet. Because limited research is available regarding pet–owner co-sleeping in non-adult samples, the aim of this two-part study was to explore whether co-sleeping improves sleep quality in adolescents, an age group in which poor sleep patterns are well documented. In Study One, an online survey with 265 pet-owning 13-to-17-year-old participants found that over 78% co-slept with their pet. Average sleep quality scores for co-sleepers and non-co-sleepers indicated generally poor sleep, with no differences in sleep quality depending on age, gender, or co-sleeping status. Study Two consisted of two preliminary case studies, using actigraphy on dog–adolescent co-sleepers. In both cases, high sleep concordance was observed, but owners again experienced generally poor sleep quality. Future actigraphy research is needed, including larger sample sizes and a control group of non-co-sleepers, to validate the preliminary findings from this study, but our limited evidence suggests that co-sleeping with a pet may not impact sleep quality in adolescents.

Coping Skills Mobile App to Support the Emotional Well-Being of Young People During the COVID-19 Pandemic: Protocol for a Mixed Methods Study

Background

The COVID-19 pandemic is likely to increase anxiety and distress in young people worldwide. It is important to prioritize mental health during crisis events to mitigate the negative and often long-term effects of the crises on young people, families, and society. Mental health and well-being apps represent a scalable approach for improving psychological outcomes in young people and have potential to improve the equity of service access.

Objective

The Whitu: 7 Ways in 7 Days well-being app was recently developed by our group to address the urgent need for innovative approaches to reach young New Zealanders who are struggling to cope with the COVID-19 pandemic. The aim of this study is twofold: to evaluate the acceptability of the prototype app and to examine the effectiveness of the refined app at improving mental and emotional well-being and reducing depression, anxiety, and stress in young people in New Zealand.

Methods

A two-phase mixed methods study will be undertaken to achieve these aims. During the first phase, 20 young people aged 16-30 years (including those of Māori and Pacific ethnicity) will participate in a qualitative study to help refine the prototype app. During the second phase, 90 young people aged 16-30 years will participate in a randomized waitlist-controlled trial (RCT) to evaluate the efficacy of the refined Whitu app at 4 weeks and 3 months after baseline. Outcomes will be evaluated using validated web-based questionnaires at baseline, 4 weeks, and 3 months.

Results

The study received ethics approval in May 2020, and recruitment for the focus groups commenced in June 2020. Recruitment for the RCT is expected to commence in October 2020. Participants for both study phases will be recruited via social media and web-based communities. Data collection for the RCT is expected to be completed by January 2021, and analyses are expected to be completed by March 2021. Linear mixed modelling will be used to determine between-group differences in psychological outcomes.

Conclusions

There is an urgent need to develop culturally appropriate, scalable mental health interventions to address the psychological consequences of the COVID-19 pandemic. In this study, we will develop and test an evidence-based well-being app that, if effective, can be made available to all young people in New Zealand and internationally.

Do sleep disturbances in depressed adolescents improve following psychological treatment for depression?

BACKGROUND

Persistent sleep disturbances are one of the most common symptoms of Major Depressive Disorder (MDD) in adolescence. These are not typically targeted in psychological treatments and it is not known if psychological treatment for depression improves sleep.

METHODS

Secondary analyses were conducted using data from a large, multi-centre, randomised controlled trial (Goodyer et al., 2017b). Young people aged 12-18 years (N = 465; 75% female) met diagnostic criteria for Major Depressive Disorder, based on the Kiddie-Schedule for Affective Disorders and Schizophrenia (K-SADS). They were randomised to one of three psychological treatments. Sleep difficulties were assessed at baseline, post-treatment (36 weeks) and one year follow up (86 weeks) with the K-SADS, and the Mood and Feelings Questionnaire (MFQ).

RESULTS

At baseline, 92% of young people exhibited clinically significant sleep difficulties. Exploratory analyses suggest that sleep difficulties significantly decreased from baseline to end of treatment on self-report and interview-based measures, and this decrease was maintained at follow up. Reduction in sleep difficulties did not differ between the psychological treatments. Approximately, half of young people reported residual sleep difficulties at the end of treatment and at follow-up.

LIMITATIONS

This paper reports secondary data analyses and findings are exploratory.

CONCLUSIONS

Tentative results suggest that psychological treatments for depression reduced sleep problems for some participants. However, young people with treatment-resistant sleep problems may benefit from adjunctive sleep interventions. Future work with a range of sleep measures is needed to determine those who have residual sleep problems at the end of treatment and post-treatment follow-up.

A Review of Pediatric Nonpharmacological Sleep Interventions: Effects on Sleep, Secondary Outcomes, and Populations With Co-occurring Mental Health Conditions

Sleep problems are common in school-age children and linked to numerous negative outcomes. Sleep disturbances are particularly common in children with mental health disorders, such as attention-deficit/hyperactivity disorder, depression, and anxiety. Despite frequent use of nonpharmacological pediatric sleep interventions to treat common sleep problems, there is a paucity of research on whether these interventions are effective. Further, it is unclear whether by targeting sleep, these interventions lead to broader improvements in the domains of functioning that are commonly affected by poor sleep. The present review includes 20 studies that evaluated nonpharmacological sleep treatments for school-aged youth, including 5 studies specifically focused on youth with externalizing or internalizing problems. Multimodal approaches consisting of psychoeducation and sleep hygiene in combination with other components were effective at treating insomnia and general sleep problems in typically developing samples. The addition of behavioral parent training to sleep interventions was effective for youth with externalizing problems, whereas incorporating cognitive strategies into sleep interventions for youth with internalizing problems was found to be ineffective. A variety of secondary outcomes were examined, with the strongest support emerging for improvement in anxiety and behavioral problems. Implications for clinical practice and future research directions are discussed.

Healthy Eating, Physical Activity, and Sleep Hygiene (HEPAS) as the Winning Triad for Sustaining Physical and Mental Health in Patients at Risk for or with Neuropsychiatric Disorders: Considerations for Clinical Practice

Neuropsychiatric disorders stem from gene-environment interaction and their development can be, at least in some cases, prevented by the adoption of healthy and protective lifestyles. Once full blown, neuropsychiatric disorders are prevalent conditions that patients live with a great burden of disability. Indeed, the determinants that increase the affliction of neuropsychiatric disorders are various, with unhealthy lifestyles providing a significant contribution in the interplay between genetic, epigenetic, and environmental factors that ultimately represent the pathophysiological basis of these impairing conditions. On one hand, the adoption of Healthy Eating education, Physical Activity programs, and Sleep hygiene promotion (HEPAS) has the potential to become one of the most suitable interventions to reduce the risk to develop neuropsychiatric disorders, while, on the other hand, its integration with pharmacological and psychological therapies seems to be essential in the overall management of neuropsychiatric disorders in order to reduce the disability and improve the quality of life of affected patients. We present an overview of the current evidence in relation to HEPAS components in the prevention and management of neuropsychiatric disorders and provide suggestions for clinical practice.

Adolescent-Sleep-Intervention Research: Current State and Future Directions

Emerging evidence suggests that cognitive-behavioral interventions should be considered as a first-line treatment for adolescent sleep problems and can also address associated mental health concerns. This article’s aim is to prioritize future directions for this research. Studies are needed that (a) leverage innovative technology, which may allow for a more personalized-medicine approach to care; (b) use alternative research designs, such as treatment-optimization strategies; (c) evaluate mechanisms of therapeutic improvements, including mediators and moderators of change, predictors of treatment adherence, dose–response relationships, and specificity of effects of different treatment components; (d) “scale up” the interventions so that a large proportion of adolescents can access them; and (e) develop flexible approaches to delivery (e.g., online platforms) and stepped-care guidelines. National and international standards of secondary school start times of 8:30 a.m. or later are also needed. The field is now mature enough to take these next steps, which will enhance the effectiveness and public health impact of these interventions.

Cognitive Behavioral Therapy for Insomnia (CBT-i) in School-Aged Children and Adolescents

Insomnia is one of the most prevalent sleep disorders in school-aged children and adolescents. Although cognitive behavioral therapy for insomnia (CBT-i) is the first-line treatment for adults, and existing studies show promising effects also for children and adolescents, the number of randomized controlled trials in younger age groups is rather small. CBT-i techniques for school-aged children and adolescents include bedtime shifts (including sleep restriction), stimulus control, thought challenging, psychoeducation, and relaxation techniques. The integration of parents, especially in school-aged children with insomnia, is highly recommended. More research is needed to investigate specific characteristics and models of child and adolescent insomnia.

"Let's talk about sleep": a qualitative examination of levers for promoting healthy sleep among sleep-deprived vulnerable adolescents

OBJECTIVE

Deficient sleep is highly prevalent in disadvantaged adolescents and contributes to a range of adverse health and behavioral outcomes. We examined mediating mechanisms and strategies that adolescents adopt to improve sleep, and possible levers for promoting sleep in this population.

METHODS

We conducted three focus groups (N = 27 total, age 14-18 years) in adolescents living in low- and middle-income racially/ethnically diverse neighborhoods of Boston, Massachusetts. Participants completed a survey on their sleep and health habits prior to the moderator-led discussions. Discussions were audio-recorded, transcribed, and thematically analyzed.

RESULTS

The study population did not meet the minimum sleep recommendations, and we found a high prevalence of "social jet-lag." We also identified a disconnect between the acknowledgment of the importance of sleep and actual behavior, especially for electronic use. Phone use and screen time were the most commonly cited barriers to a good night's sleep, along with caffeine consumption, which was also high in this sample. There was also a general lack of awareness of sleep hygiene practices and recommendations. Participants reported regulating food intake and physical activity, using allopathic sleep aids, creating a comfortable sleeping environment, and a routine as some strategies to improve sleep.

CONCLUSION

Results from this study suggest facilitating the linkage between participant-generated mediating factors and strategies for better-designed interventions. These include making the negative impact of sleep on health more explicit, improving youth awareness about sleep hygiene, targeting caffeine consumption and electronic use, and introducing sleep recommendations through appropriate and effective channels.

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.
