Sleep and anxiety in late childhood and early adolescence

Changes in Restless Sleep, Self-Control, and Alcohol-Related Problems with Police from Late Adolescence to Adulthood

Sleep quality is crucial for healthy adolescent brain development, which has downstream effects on self-control and involvement in risky behaviors, such as alcohol use. While previous studies have found that sleep and facets of self-control are associated with patterns of alcohol use, few have assessed whether these constructs are tied to alcohol-related problems with law enforcement during the transitional period from adolescence to adulthood. The current study uses self-report panel data from ages 16 to 27 from a population-based sample of U.S. youth (N = 956; 36.86% female). The goal of the current study is to assess the association between changes in restless sleep, impulsivity, sensation seeking, and problems with police during or shortly after consuming alcohol from adolescence to adulthood to begin to address this gap in the existing literature. Results from a multivariate latent growth curve model reveal that faster increases in restless sleep and slower declines in impulsivity are associated with slower declines in police contact. Correlated changes between restless sleep, impulsivity, and police contact are slightly greater from ages 16-21 than for ages 22-27, with males showing stronger associations. The reported results suggest that identifying developmental mechanisms between changes in poor sleep, impulsivity, and alcohol use behaviors during this life-course phase will be crucial moving forward to help divert youth away from alcohol-related contact with the police.

Internet-delivered cognitive behavioral therapy for adolescents with insomnia: Feasibility and preliminary efficacy

BACKGROUND

Insomnia is common in adolescents. This study evaluated feasibility and preliminary efficacy of a six-week internet-delivered cognitive-behavioral therapy for insomnia (ICBT-I) in adolescents.

METHODS

In this uncontrolled pilot study, participants (n = 27, 78% female) completed assessments pre- and post intervention. Data on recruitment, adherence to treatment, treatment activity, satisfaction and credibility was collected to assess feasibility. Self-reported insomnia symptoms, sleep parameters as well as depression, anxiety and daytime function were also assessed.

RESULTS

Participants showed good adherence to treatment and found the intervention overall credible and satisfactory. From pre- to post-assessment, statistically significant improvements were found for insomnia symptoms (p < .001; d = 1.02), sleep onset latency (p < .001; d = .39), wake after sleep onset (p = .001; d = .34), sleep efficiency (p < .001; d = .5) and depression (p = .01, d = .37). Changes in scores of total sleep time, generalized anxiety, daytime sleepiness and functional disability were not significant.

CONCLUSIONS

The present study indicates that ICBT-I is well accepted by adolescents, that insomnia symptoms and sleep parameters can improve following the intervention, and that co-morbid symptoms of depression can be reduced. Due to the limited sample size and the uncontrolled design, the suggested results need to be replicated in well-powered controlled clinical trials.

Consolidation of emotional memory during waking rest depends on trait anxiety

A short period of eyes-closed waking rest improves long-term memory for recently learned information, including declarative, spatial, and procedural memory. However, the effect of rest on emotional memory consolidation remains unknown. This preregistered study aimed to establish whether post-encoding rest affects emotional memory and how anxiety levels might modulate this effect. Participants completed a modified version of the dot-probe attention task that involved reacting to and encoding word stimuli appearing underneath emotionally negative or neutral photos. We tested the effect of waking rest on memory for these words and pictures by manipulating the state that participants entered just after this task (rest vs. active wake). Trait anxiety levels were measured using the State-Trait Anxiety Inventory and examined as a covariate. Waking rest improved emotional memory consolidation for individuals high in trait anxiety. These results suggest that the beneficial effect of waking rest on memory extends into the emotional memory domain but depends on individual characteristics such as anxiety.

Delivering a sleep intervention across a youth mental health service using non-expert practitioners: A service evaluation

AIMS

Poor sleep is highly prevalent in young people and increases risk of mental health difficulties, yet access to sleep interventions remains limited. This paper evaluates the use of a sleep intervention delivered by non-expert practitioners in a secondary care youth mental health service.

METHOD

Assistant psychologists were trained to deliver a six-session 1:1 cognitive-behavioural sleep intervention adapted for use with young people with mental health difficulties. A within-subject design assessed clinical outcomes relating to sleep (Insomnia Severity Index), psychological distress and personal goals (Goal Based Outcome Measures) at four time points.

RESULTS

High referral, intervention take-up (82.82%) and completion (70%) rates were reported, together with high baseline levels of insomnia (Insomnia Severity Index mean 20.47, SD 3.68) and poor sleep efficiency (56.36%, SD 17.23). Fifty-six young people (average age 19.2 years, SD 3.25) were included in the outcome analysis. Statistically and clinically significant improvements were seen across all outcome measures, with 68% no longer meeting clinical threshold (ISI ≥15) for insomnia at endpoint.

CONCLUSIONS

This study demonstrates exceptionally high levels of clinical need and engagement with a sleep intervention adapted specifically for young people with mental health difficulties. Whilst limited by the uncontrolled design, large improvements in insomnia and psychological distress support its effectiveness and utility in clinical settings. More robust implementation and evaluation is warranted in broader youth mental health services to promote earlier access.

Associations between sleep health, negative reinforcement learning, and alcohol use among South Florida college students with elevated internalizing symptoms

Negative reinforcement is proposed to mediate associations between sleep and alcohol use, especially among people with depression and/or anxiety symptoms. Worse sleep (e.g., shorter duration, less efficiency, more irregular timing) exacerbates negative emotions, which alcohol may temporarily relieve. Not yet examined, we propose sleep indirectly impacts early stages of alcohol use via differences in negative reinforcement learning (NRL), since sleep impacts emotion, reward response, and learning. The current study aimed to replicate associations between sleep and alcohol use, test associations with NRL, and examine indirect associations between sleep health and alcohol use via NRL among 60 underage college students (ages 18-20 years, 77% female) varying in depression and anxiety symptoms. Participants wore Fitbit smartwatches and completed daily diaries measuring sleep and substance use for ∼14 days before completing two computer tasks assessing social (SNRL) and monetary (MNRL) negative reinforcement learning. Robust generalized linear models tested direct associations within the proposed model. SNRL performance was positively associated with alcohol use, but no other associations were observed. Statistical mediation models failed to indicate indirect effects of sleep on alcohol use via SNRL or MNRL performance. Post-hoc exploratory models examining depression and anxiety symptoms as moderators of direct associations indicated several interactions. Positive associations between sleep timing variability and alcohol use were weakened at higher anxiety symptom severity and stronger at higher depression symptom severity. The positive association between SNRL performance and alcohol use was also stronger at higher depression symptom severity. Among students with elevated depression symptoms, variable sleep timing and stronger SNRL performance were independently associated with more alcohol use, but indirect effects were not supported. Future research should replicate findings, confirm causality of interactions, and examine sleep timing and behavioral responses to negative social stimuli as targets for improving alcohol-related outcomes among underage college students with elevated depressive symptoms.

Temporal network of experience sampling methodology identifies sleep disturbance as a central symptom in generalized anxiety disorder

BACKGROUND

A temporal network of generalized anxiety disorder (GAD) symptoms could provide valuable understanding of the occurrence and maintenance of GAD. We aim to obtain an exploratory conceptualization of temporal GAD network and identify the central symptom.

METHODS

A sample of participants (n = 115) with elevated GAD-7 scores (Generalized Anxiety Disorder 7-Item Questionnaire [GAD-7] ≥ 10) participated in an online daily diary study in which they reported their GAD symptoms based on DSM-5 diagnostic criteria (eight symptoms in total) for 50 consecutive days. We used a multilevel VAR model to obtain the temporal network.

RESULTS

In temporal network, a lot of lagged relationships exist among GAD symptoms and these lagged relationships are all positive. All symptoms have autocorrelations and there are also some interesting feedback loops in temporal network. Sleep disturbance has the highest Out-strength centrality.

CONCLUSIONS

This study indicates how GAD symptoms interact with each other and strengthen themselves over time, and particularly highlights the relationships between sleep disturbance and other GAD symptoms. Sleep disturbance may play an important role in the dynamic development and maintenance process of GAD. The present study may develop the knowledge of the theoretical model, diagnosis, prevention and intervention of GAD from a temporal symptoms network perspective.

Hypnosis with depressed children and teens: Building skills, creating connection

Depression in children and teens has been on the rise for several years. Recent increases in anxiety and loneliness, both contributors to the development of depression, are putting more young people at risk for chronic and comorbid mental health struggles. The use of hypnosis with depressed children offers the opportunity to target the identified skills depressed and anxious children need and is a modality clinicians should embrace. This article describes how to create hypnotic interventions focusing on improved emotional and cognitive management, better sleep, and the ability to make positive social connections. Such interventions serve to not only build the resources depressed children need for recovery, but also support a paradigm shift toward prevention in children and families.

Sleep-Related Problems and Pediatric Anxiety Disorders

Sleep-related problems are highly prevalent among childhood and adolescent anxiety disorders. The objective of this review was to summarize the relevant clinical research literature as it pertains to the nature of the association between sleep-related problems and youth anxiety, developmental factors relevant to this association, and intervention efforts to target comorbid sleep challenges and anxiety. Limitations of the literature and future directions are discussed.

Neighborhood determinants of sleep and the moderating role of cultural factors among native adolescents

OBJECTIVE

This study examined the association between neighborhood social environment and sleep among urban American Indian and Alaska Native (AI/AN) adolescents as well as the moderating role of cultural factors in this association.

METHOD

The analytic sample included 133 urban AI/AN adolescents (age 12-16, 57.1% female, Mage = 14.03, SDage = 1.35). Perceived neighborhood social environment included safety and cohesion. Cultural factors included AI/AN cultural identification and historical loss. Sleep duration, efficiency, and wake after sleep onset (WASO) were measured via actigraphy. Sleep disturbance was measured via a questionnaire.

RESULTS

Greater neighborhood safety was significantly associated with lower sleep disturbance (b = -2.17, SE = 0.8, p = .008), higher sleep efficiency (b = 1.75, SE = 0.64, p = .006), and lower WASO (b = -8.60, SE = 3.34, p = .01). Neighborhood cohesion was not associated with any sleep outcomes. Cultural factors moderated the association between neighborhood social environment and sleep outcomes (p < .05). Specifically, both neighborhood safety and cohesion were associated with lower sleep disturbance, only among individuals reporting higher levels of AI/AN cultural identification. Further, neighborhood safety was associated with greater sleep efficiency and lower WASO (i.e., better sleep) only among adolescents with higher contemplation of historical loss.

CONCLUSIONS

Findings highlight the importance of considering cultural factors in addressing sleep and health disparities. AI/AN cultural identification and a sense of historical loss may be important targets for identifying adolescents who might benefit the most from policies and interventions focused on improving the social environment in order to improve sleep and other health outcomes.

Examining the Biopsychosocial Factors Related to Lifetime History of Concussion in Children and Youth

This study investigated the prevalence of lifetime concussions, related psychosocial problems, and post-concussion recovery rates in a clinical sample of children and youth. Participants were 24,186 children and youth (M = 11.9 years, SD = 3.5) who completed an interRAI Child and Youth Mental Health Assessment at mental health agencies across Ontario, Canada. In addition to the expected physiological correlates, results found concussions to be more prevalent in children and youth with attention deficit hyperactivity disorders, anxiety disorders, disruptive behaviour disorders, mood disorders, and those involved in self-harm, harm to others, destructive aggression, and internalizing and externalizing symptoms. The results of this study add to our understanding of children and youth's experiences with concussions. Clinical implications and recommendations are discussed to maximize the effectiveness of evidence-based interventions related to concussion recovery.

Associations between social jetlag trajectories and body mass index among young adults

STUDY OBJECTIVES

This study employed longitudinal data collected repeatedly from individuals over the course of several years to examine the trajectories of social jetlag from ages 11 to 22 years and their associations with subsequent body mass index (BMI). Potential sex differences were also investigated.

METHODS

Data were obtained from two longitudinal studies conducted in Taiwan (N = 4287). Social jetlag was defined as ≥ 2 hours of absolute difference in sleep midpoint between weekdays and weekends. BMI was calculated using weight (kg)/height(m)2 and categorized as underweight (<18 kg/m2), normal weight (18 kg/m2 ≤ BMI < 24 kg/m2), overweight (24 kg/m2 ≤ BMI < 27 kg/m2), and obese (≥27 kg/m2). Group-based trajectory modeling and multinomial logistic regression were applied to investigate study objectives.

RESULTS

Four distinct trajectories of social jetlag throughout the adolescent years were identified, with corresponding proportions as follows: low-stable (42%), moderate-decreasing (19%), low-increasing (22%), and chronic (17%) trajectories. Among males, the risk of being underweight (aOR, 1.96; 95% CI: 1.35 to 2.84) or obese (aOR, 1.40; 95% CI: 1.02 to 1.92) was higher in individuals with a low-increasing trajectory than in those with a low-stable trajectory. Among females, those with a low-increasing (aOR, 1.61; 95% CI: 1.02 to 2.54) or chronic (aOR, 2.04; 95% CI: 1.27 to 3.25) trajectory were at a higher risk of being obese relative to those with a low-stable trajectory.

CONCLUSIONS

Addressing the development of increasing or chronic social jetlag during adolescence can help prevent abnormal BMI in young adulthood. Practitioners should consider sex differences in treatment or consultation.

A meta-analysis of longitudinal studies on the interplay between sleep, mental health, and positive well-being in adolescents

Objective

This review aimed to summarize longitudinal research about the interplay between sleep, mental health, and positive well-being in adolescents.

Method

Multiple search strategies were applied until 28th January 2023 to identify relevant research published in peer-reviewed journal articles or available grey literature. A final set of 63 studies were included in the systematic review and 42 in the meta-analysis.

Results

Results highlighted that long sleep duration, good sleep quality, and low insomnia symptoms were bidirectionally related to lower internalizing (Sleep T1 → Internalizing symptoms T2: r = -.20, p < .001; Internalizing symptoms T1 → Sleep T2: r = -.21, p < .001) and externalizing (Sleep T1 → Externalizing symptoms T2: r = -.15, p < .001; Externalizing symptoms T1→ Sleep T2: r = -.17, p < .001) symptoms, and to higher levels of psychological well-being (Sleep T1 → Psychological well-being T2: r = .15, p < .001; Psychological well-being T1 → Sleep T2: r = .15, p < .05). Moreover, good sleep was positively related to higher subjective well-being at a later time point (r = .18, p < .001).

Conclusions

Overall, these findings suggest a bidirectional relation between different aspects of sleep, mental health, and positive well-being.

Psychometric properties of the Chinese Family Assessment Instrument: evidence from mainland China

Regarding the assessment of family functioning in Chinese people, there are several research gaps. First, although there are some instruments in the field, there are very few validated instruments. Second, while some translated measures have been developed, there are very few assessment tools based on indigenous Chinese concepts. Third, compared to Hong Kong, research on family assessment is relatively inactive in mainland China. Fourth, there are very few family assessment tools to assess perceived family functioning in older children and early adolescents. Fifth, few studies used large samples to validate family assessment tools. Sixth, researchers seldom utilized longitudinal data to examine the psychometric properties of family assessment tools. Finally, few studies have examined factorial validity across samples and time to demonstrate the stability of Chinese family assessment measures. In Hong Kong, based on focus group data (i.e., indigenous concepts of family functioning) and an integration with the family science literature, we have developed the Chinese Family Assessment Instrument (C-FAI) to assess perceived family functioning according to the perception of adolescents. Results showed that the C-FAI possessed good reliability and validity. Specifically, five dimensions of the measure (mutuality, communication, conflict, parental concern and parental control) were supported via exploratory factor analysis and confirmatory factor analysis. Convergent validity and reliability of the C-FAI were illustrated. To understand the psychometric properties of the C-FAI in mainland China, we collected three waves of data from students in the period of preadolescence and early adolescence in mainland China (N = 3,732). Based on the data, we examined the psychometric properties of the measure, particularly factor invariance in different samples and at different times. Confirmatory factor analysis provided support for the five dimensions in C-FAI, including factorial invariance in terms of configuration, factor loading, intercepts, and over time. There was evidence for convergent validity and discriminant validity of the measure. Finally, reliability analyses showed that the total C-FAI scale and its subscales are internally consistent. The present findings suggest that family researchers and practitioners can use the C-FAI to objectively assess perceived family functioning in preadolescence and early adolescence in different Chinese communities.

Attentional Control Accounts for the Association Between Anxiety Sensitivity and Sleep Efficiency in Clinic-Referred Youth

Youth with anxiety disorders report difficulty falling asleep and returning to sleep after sleep onset (i.e., poor sleep efficiency). Anxiety sensitivity, the excessive attention to physical symptoms of anxiety and their threatening interpretations, has been linked to poor sleep efficiency. We tested a conceptual model wherein attentional control, attentional focusing and attentional shifting would account for the relationship between anxiety sensitivity and poor sleep efficiency. 255 youths (6-17 years old, 78% Hispanic/Latino) who presented to a university-based research clinic completed measures on anxiety sensitivity, sleep, and attentional control. Poorer sleep efficiency was significantly correlated with higher anxiety sensitivity and lower attentional control, attentional focusing, and attentional shifting. Higher anxiety sensitivity was significantly correlated with lower attentional control and attentional focusing. Attentional control and attentional focusing, not attentional shifting, accounted for the relationship between anxiety sensitivity and poor sleep efficiency. These findings identify attentional control and attentional focusing as variables that may explain the association between anxiety sensitivity and sleep efficiency in youth.

Sleep Disturbances and Delayed Sleep Timing are Associated with Greater Post-Traumatic Stress Symptoms in Youth Following Hurricane Harvey

Sleep patterns following a natural disaster are associated with mental health difficulties, but research in youth samples has been limited to subjective reports of sleep. Participants (N = 68, 8-17 years old) completed an assessment 6-9 months after Hurricane Harvey, which included subjective measures of sleep, chronotype, hurricane-related post-traumatic stress symptoms, and one week of actigraphy. Prior to the hurricane, parents provided reports on emotional symptoms. Controlling for age, sex, socioeconomic status, participation time, and pre-hurricane emotional symptoms, subjective sleep disturbances and an eveningness chronotype were associated with greater post-traumatic stress, with the strongest effects observed for re-experiencing, negative cognitions/mood, and arousal/reactivity symptoms. Later sleep timing as measured by actigraphy was associated with greater arousal/reactivity symptoms and shorter sleep duration was associated with greater avoidance symptoms. As extreme weather-related events are expected to become more frequent and severe, these findings contribute to models of youth risk and resilience.

Altered sleep architecture in children and adolescents with Down syndrome

OBJECTIVE

Children with Down syndrome (DS) may experience changes in sleep architecture (i.e., different sleep stages) that then affect waketime functioning, including learning, mood, and disruptive behavior. For designing and testing interventions, it is important to document any differences in sleep architecture in children with DS with and without co-occurring diagnoses, including neuropsychiatric diagnoses and obstructive sleep apnea (OSA).

METHODS

A retrospective cohort study was performed at Massachusetts General Hospital for children and adolescents with DS who underwent polysomnography (PSG) between August 2016 and July 2022. Patient data collected from the electronic medical record included diagnoses, age at PSG, and PSG report. Statistical analysis included unpaired T tests to test hypotheses about differences in sleep architecture within age groups, and differences between children with DS and a co-occurring diagnosis. One way ANOVA was used to determine statistical significance of OSA severity within patients with DS.

RESULTS

When compared by age group, those with DS had negative changes in sleep architecture (e.g., less sleep and more wake) when compared to normative data. Within this cohort, having a co-occurring diagnosis of autism resulted in further, negative effects on sleep architecture. 89% of those with DS had diagnosed OSA but only those with severe OSA experienced negative effects on sleep architecture.

CONCLUSION

Age is an important covariate when studying the sleep of children with DS and neurotypical children. Studies are needed to test whether minimizing the observed differences in sleep architecture will translate to improved learning, mood, and behavioral outcomes, and how treating OSA affects sleep architecture.

Nucleus Reuniens: Modulating Negative Overgeneralization in Periadolescents with Anxiety

Background

Anxiety affects 4.4-million children in the United States with an onset between childhood and adolescence, a period marked by neural changes that impact emotions and memory. Negative overgeneralization - or responding similarly to innocuous events that share features with past aversive experiences - is common in anxiety but remains mechanistically underspecified. The nucleus reuniens (RE) has been considered a crucial candidate in the modulation of memory specificity. Our study investigated its activation and functional connectivity with the medial prefrontal cortex (mPFC) and hippocampus (HPC) as neurobiological mechanisms of negative overgeneralization in anxious youth.

Methods

As part of a secondary data analysis, we examined data from 34 participants between 9-14 years (mean age ± SD, 11.4 ± 2.0 years, 16 females) with varying degrees of anxiety severity. During the Study session participants rated images as negative, neutral, and positive. After 12-hours, participants returned for a Test session, where they performed a memory recognition test with repeated (targets) and similar (lures) images. Labeling negative relative to neutral lures as "old" (false alarms) was our operational definition of negative overgeneralization.

Results

Negative relative to neutral false alarmed stimuli displayed elevated RE activation (at Study and Test) and increased functional connectivity with the CA1 (at Test only). Elevated anxiety severity was associated with reductions in the RE-mPFC functional coupling for neutral relative to negative stimuli. Exploratory analyses revealed similar patterns in activation and functional connectivity with positive stimuli.

Conclusions

Our findings demonstrate the importance of the RE in the overgeneralization of memories in anxious youth.

Disturbed sleep and patterns of psychiatric symptoms and function in a school-based sample of adolescents

BACKGROUND

Sleep problems are common in adolescence and often related to psychopathology and impaired functioning. However, most studies have used summative scores, and little is known about how adolescents with disrupted sleep perceive their specific symptoms and dysfunctions. This study explored differences in levels of psychiatric symptoms and functional ability between Swedish adolescents with and without self-reported disturbed sleep in a school-based sample.

METHODS

Swedish adolescents (n = 618, mean age 15.7+/-1.9yrs) answered the PROMIS pediatric measures for fatigue, anxiety, depression, pain interference, anger, physical activity and peer and family relationships. Logistic regression analyses were performed to assess differences between respondents with and without disturbed sleep.

RESULTS

Disturbed sleep was associated with higher levels of symptoms of fatigue, anxiety, depression, anger and pain interference, as well as lower functional abilities in terms of physical activity and peer- and family relationships. Adolescents reporting disturbed sleep generally displayed a pattern of impaired executive functioning, internal emotional distress and school- and sleep related worry and dysfunction, as compared to physical disability, aggressive behavior, stress and generalized worry.

CONCLUSIONS

The present study adds to the understanding of how disturbed sleep and specific psychiatric symptoms and functional ability are interrelated, which may also have clinical implications.

Adverse childhood experiences, sleep problems, low self-control, and adolescent delinquency: A longitudinal serial mediation analysis

Several studies link adverse childhood experiences (ACEs) to delinquency. Yet, developmental sequalae accounting for this association remain unclear, with previous research limited by cross-sectional research designs and investigations of singular mediating processes. To redress these shortcomings, this study examines the longitudinal association between ACEs and delinquency as mediated by both sleep problems and low self-control, two factors which past research implicates as potentially important for understanding how ACEs contribute to antisocial behavior. Data collected from 480 adolescents (71.3% boys; 86.3% White) and their parents participating in the Michigan Longitudinal Study was used to conduct a serial mediation analysis. The association between ACEs (prior to age 11) and delinquency in late adolescence was found to operate indirectly via sleep problems in early adolescence and low self-control in middle adolescence. Nonetheless, a direct association between ACEs and later delinquency remained. Pathways through which ACEs contribute to later delinquency are complex and multiply determined. Findings indicate that early behavioral interventions, including improving sleep and self-control, could reduce later delinquency. Still, more research is needed to identify additional avenues through which the ACEs-delinquency association unfolds across development.

Protocol for a randomised controlled trial evaluating the effect of a CBT-I smartphone application (Sleep Ninja®) on insomnia symptoms in children

BACKGROUND

Sleep is necessary for healthy development and mental wellbeing. Despite this, many children do not get the recommended duration of sleep each night, and many experience sleep problems. Although treatable, existing interventions for sleep disturbance are time-consuming, burdensome for families, and focus on providing behavioural strategies to parents rather than upskilling children directly. To address this gap, we modified Sleep Ninja®, an evidence-based cognitive behavioural therapy for insomnia (CBT-I) smartphone app for adolescent sleep disturbance, to be appropriate for 10 to 12 year olds. Here, we describe the protocol for a randomised controlled trial to evaluate the effect of Sleep Ninja on insomnia and other outcomes, including depression, anxiety, sleep quality, and daytime sleepiness, and explore effects on the emergence of Major Depressive Disorder (MDD), compared to an active control group.

METHODS

We aim to recruit 214 children aged 10 to 12 years old experiencing disturbed sleep. Participants will be screened for inclusion, complete the baseline assessment, and then be randomly allocated to receive Sleep Ninja, or digital psychoeducation flyers (active control) for 6-weeks. The primary outcome, insomnia symptoms, along with depression, anxiety, sleep quality, and daytime sleepiness will be assessed at 6-weeks (primary endpoint), 3-months, and 9-months post-baseline (secondary and tertiary endpoints, respectively). A mixed model repeated measures analytic approach will be used to conduct intention-to-treat analyses to determine whether reductions in insomnia and secondary outcomes are greater for those receiving Sleep Ninja relative to the control condition at the primary and secondary endpoints. The difference in relative risk for MDD onset will be explored at 9-months and compared between conditions.

DISCUSSION

This is the first clinical trial examining the effects of a CBT-I smartphone app in children experiencing sleep disturbance. Results will provide empirical evidence about the effects of Sleep Ninja on insomnia and other mental health outcomes.

Anxious-Withdrawal and Sleep Problems during Adolescence: The Moderating Role of Peer Difficulties

Anxious-withdrawal is a well-established individual risk factor for psychosocial difficulties during adolescence. It is unknown, however, whether it also places youth at increased risk for physical health problems, such as sleep difficulties. This study examines the concurrent and prospective associations between anxious-withdrawal and six types of sleep difficulties (i.e., sleeping too much, sleeping too little, talking/walking in sleep, being overtired, nightmares, and general trouble sleeping). We further evaluate whether these associations differ for adolescents who are high versus low in exclusion and victimization. The participants were 395 adolescents (Mage = 13.61 years; 35% ethnic minority) who completed peer nominations of anxious-withdrawal, exclusion, and victimization at Time 1 (T1). Their mothers completed reports of sleep difficulties at T1 and at Time 2 (T2). Path analyses revealed unique associations between anxious-withdrawal and several types of sleep difficulties (e.g., sleeping too much) at T1. Analyses also revealed a significant interaction effect between T1 anxious-withdrawal and exclusion/victimization such that anxious-withdrawal was prospectively associated with trouble sleeping only for those young adolescents who are highly excluded/victimized. Our findings are the first to link anxious-withdrawal to a physical health outcome in adolescence and point to the need for future research to not only examine anxious-withdrawal and physical health but also to include assessments of peer difficulties.

Development of the Nighttime Parenting Scale: Differentiating nighttime versus general parenting practices and their impact on youth sleep health

OBJECTIVES

The current study provides a novel method of assessing the impact of nighttime parenting practices on youth sleep health during the sensitive transition from childhood to adolescence (ie., peri-puberty). Specifically, we aimed to advance the measurement of nighttime parenting by developing a conceptually driven questionnaire for use in research and clinical settings.

METHOD

A total of 625 parents (67.9% mothers) of peripubertal youth (age M=11.6, SD=1.31) were recruited online and completed self-report questionnaires. The sample was primarily White (67.4%), followed by 16.5% Black, 13.1% Latinx, and 9.6% Asian. Factor structure was examined through four empirically-driven stages (ie, exploratory factor analyses, confirmatory factor analyses, examining internal and test-retest reliability, and indices of validity). Furthermore, the current study sought to validate nighttime parenting as a unique construct by exploring associations with peripubertal youth sleep health.

RESULTS

A factor structure consisting of six dimensions of nighttime parenting was established (ie, nighttime supportiveness, hostility, physical control, limit-setting, media monitoring, and co-sleeping behaviors). Furthermore, the current measure demonstrated strong psychometric properties. Finally, the established dimensions were cross-sectionally associated with youth sleep health indices.

CONCLUSIONS

This study extends previous research by examining the influence of distinct domains of parenting practices that specifically occur at nighttime and how these differentially relate to youth sleep health. Results suggest that intervention and/or prevention programs targeting sleep should place emphasis on fostering positive parenting at nighttime as a strategy for creating an evening environment that is conducive to optimizing youth sleep health.

Prospective Associations of Childhood Housing Insecurity With Anxiety and Depression Symptoms During Childhood and Adulthood

Importance

Childhood housing insecurity has dramatically increased in the US in recent decades, but whether an association with adverse mental health outcomes exists after adjusting for repeated measures of childhood poverty is unclear.

Objective

To test whether childhood housing insecurity is associated with later anxiety and depression symptoms after adjusting for time-varying measures of childhood poverty.

Design, Setting, and Participants

This prospective cohort study included individuals aged 9, 11, and 13 years at baseline from the Great Smoky Mountains Study in western North Carolina. Participants were assessed up to 11 times from January 1993 to December 2015. Data were analyzed from October 2021 to October 2022.

Exposure

Participants and their parents reported social factors annually when participants were 9 to 16 years of age. A comprehensive measure of childhood housing insecurity was constructed based on frequent residential moves, reduced standard of living, forced separation from home, and foster care status.

Main Outcomes and Measures

Between ages 9 and 16 years, the Child and Adolescent Psychiatric Assessment was used up to 7 times to evaluate childhood anxiety and depression symptoms. Adult anxiety and depression symptoms were assessed at ages 19, 21, 26, and 30 years using the Young Adult Psychiatric Assessment.

Results

Of the 1339 participants (mean [SD] age, 11.3 [1.63] years), 739 (55.2%; 51.1% weighted) were male; 1203 individuals assessed up to 30 years of age were included in the adulthood outcome analyses. Standardized mean (SD) baseline anxiety and depression symptom scores were higher among children who experienced housing insecurity than among those who never experienced housing insecurity (anxiety: 0.49 [1.15] vs 0.22 [1.02]; depression: 0.20 [1.08] vs -0.06 [0.82]). Individuals who experienced childhood housing insecurity had higher anxiety symptom scores (fixed effects: standardized mean difference [SMD], 0.21; 95% CI, 0.12-0.30; random effects: SMD, 0.25; 95% CI, 0.15-0.35) and higher depression symptom scores (fixed effects: SMD, 0.18; 95% CI, 0.09-0.28; random effects: SMD, 0.26; 95% CI, 0.14-0.37) during childhood. In adulthood, childhood housing insecurity was associated with higher depression symptom scores (SMD, 0.11; 95% CI, 0.00-0.21).

Conclusions and Relevance

In this cohort study, housing insecurity was associated with anxiety and depression during childhood and with depression during adulthood. Because housing insecurity is a modifiable, policy-relevant factor associated with psychopathology, these results suggest that social policies that support secure housing may be an important prevention strategy.

Sleep fails to depotentiate amygdala-reactivity to negative emotional stimuli in youth with elevated symptoms of anxiety

Sleep-related problems often precede escalating anxiety in early adolescence. Pushing beyond broad sleep-mental health associations and toward mechanistic theories of their interplay can inform etiological models of psychopathology. Recent studies suggest that sleep depotentiates neural (e.g., amygdala) reactivity during reexposure to negative emotional stimuli in adults. Persistent amygdala reactivity to negative experiences and poor sleep characterize anxiety, particularly at the transition to adolescence. We propose that sleep depotentiates amygdala reactivity in youth but fails to do so among youth with anxiety. Participants (n = 34; 18 males; age, mean [M] = 11.35, standard deviation [SD] = 2.00) recruited from the community and specialty anxiety clinics viewed valenced images (positive, negative, and neutral) across two fMRI sessions (Study, Test), separated by a 10-12-hour retention period of sleep or wake (randomized). Mixed linear models regressed basolateral amygdala (BLA) activation and BLA-medial prefrontal cortex (mPFC) functional connectivity to negative images on Time, Condition, and Anxiety Severity. There were greater reductions in BLA activations to negative target images from Study to Test in the Sleep Condition, which was blunted with higher anxiety (b = -0.065, z = -2.355, p = 0.019). No such sleep- or anxiety-related effects were observed for BLA-mPFC functional connectivity (ps > 0.05). Sleep supports depotentiation of amygdala reactivity to negative stimuli in youth, but this effect is blunted at higher levels of anxiety. Disruptions in sleep-related affective habituation may be a critical, modifiable driver of anxiety.

Sleep Deprivation and Insomnia in Adolescence: Implications for Mental Health

Sleep changes significantly throughout the human lifespan. Physiological modifications in sleep regulation, in common with many mammals (especially in the circadian rhythms), predispose adolescents to sleep loss until early adulthood. Adolescents are one-sixth of all human beings and are at high risk for mental diseases (particularly mood disorders) and self-injury. This has been attributed to the incredible number of changes occurring in a limited time window that encompasses rapid biological and psychosocial modifications, which predispose teens to at-risk behaviors. Adolescents’ sleep patterns have been investigated as a biunivocal cause for potential damaging conditions, in which insufficient sleep may be both a cause and a consequence of mental health problems. The recent COVID-19 pandemic in particular has made a detrimental contribution to many adolescents’ mental health and sleep quality. In this review, we aim to summarize the knowledge in the field and to explore implications for adolescents’ (and future adults’) mental and physical health, as well as to outline potential strategies of prevention.

Lace Up and Mindfulness: A Randomized Controlled Trial Intervention to Reduce Emotional Eating, Anxiety, and Sleep Disturbances in Latinx and Black Youth

This study assessed the effects of a 12-week afterschool mindfulness-based diet and exercise intervention on mental and physical health in Latinx and Black youth. One hundred forty-eight boys and girls (average age = 10.1 years, SD = 1.3 years; 52% girls; 72.3% Latinx) were randomized to either the experimental group (n = 80) or the control group (n = 68). The experimental group participants engaged in fitness yoga, kickboxing, and/or spinning sessions, and mindfulness practices (e.g., breathing, meditation, and mindful eating) twice per week for 12 weeks. The control group participants engaged in a recreational play session once per week for 12 weeks. All participants completed surveys (demographics, acculturation, anxiety, emotional eating, sleep, and food intake) and had their height, weight, and percent body fat measured pre- and post-intervention. Participants wore an accelerometer for 7 days pre- and post-intervention. Repeated measures analysis of covariance indicated that the experimental group participants reported lower scores in emotional eating, anxiety, and sleep latency post-intervention compared to the control group participants. Conversely, no significant differences were observed in physical activity between the experimental and control group participants post-intervention. These findings indicate that a mindfulness-based intervention has a positive effect on emotional eating, anxiety, and sleep latency among youth of color.

Association of emotional and behavioral problems with sleep disturbance among Chinese adolescents: The moderation effect of academic performance

BACKGROUND

This study aimed to explore the association of emotional and behavioral problems with sleep disturbance among Chinese adolescents, and to test whether these associations vary with adolescents' academic performance.

METHODS

Data were from the 2021 School-based Chinese Adolescents Health Survey using a multistage, stratified-cluster, and random-sampling method to collect information from 22,684 middle school students in Guangdong Province, China.

RESULTS

Emotional problems (aOR = 1.34, 95 % CI = 1.32-1.36), conduct problems (aOR = 1.19, 95 % CI = 1.16-1.21), hyperactivity (aOR = 1.35, 95 % CI = 1.33-1.37), and peer problems (aOR = 1.06, 95 % CI = 1.04-1.09) were significantly associated with the increased risk of sleep disturbance among middle school students in Guangdong Province. The prevalence of sleep disturbance among adolescents was 29.4 %. There were significant interactions of emotional problems/conduct problems/peer problems/prosocial behavior with academic performance on sleep disturbance. Further stratification analyses by academic performance showed that adolescents with self-reported good academic performance had a higher risk of sleep disturbance than those students with self-reported average or poor academic performance.

LIMITATIONS

This study only included school students and used the cross-sectional design to preclude causality determination.

CONCLUSIONS

Our findings suggest that emotional and behavioral problems elevate the risk of sleep disturbance in adolescents. Adolescent academic performance plays a modulating role in these above-mentioned significant associations for sleep disturbance.

Sleep variability over a 2-week period is associated with restfulness and intrinsic limbic network connectivity in adolescents

STUDY OBJECTIVES

Sleep duration and intraindividual variability in sleep duration undergo substantial changes in adolescence and impact brain and behavioral functioning. Although experimental work has linked acute sleep deprivation to heightened limbic responding and reduced regulatory control, there is limited understanding of how variability in sleep patterns might interact with sleep duration to influence adolescent functioning. This is important for optimal balancing of length and consistency of sleep. Here, we investigated how objective indices of sleep duration and variability relate to stress, restfulness, and intrinsic limbic network functioning in adolescents.

METHODS

A sample of 101 adolescents ages 14-18 reported their stressors, after which they wore wrist actigraph watches to monitor their sleep and rated their restfulness every morning over a 2-week period. They also completed a resting-state fMRI scan.

RESULTS

Adolescents reporting more stress experienced shorter sleep duration and greater sleep variability over the 2-week period. Longer nightly sleep duration was linked to feeling more rested the next morning, but this effect was reduced in adolescents with high cumulative sleep variability. Sleep variability showed both linear and quadratic effects on limbic connectivity: adolescents with high sleep variability exhibited more connectivity within the limbic network and less connectivity between the limbic and frontoparietal networks than their peers, effects which became stronger once variability exceeded an hour.

CONCLUSIONS

Results suggest that cumulative sleep variability is related to stress and limbic network connectivity and shows interactive effects with sleep duration, highlighting the importance of balancing length and consistency of sleep for optimal functioning in adolescence.

Involvement in bullying and sleep disorders in Chinese early adolescents

Background

School bullying may cause sleep disorders in early adolescents. Here, we determined the relationship between school bullying (considering all the features of bullying involvement) and sleep disorders, which are the common problems in Chinese early adolescents.

Materials and methods

We conducted a questionnaire survey among 5,724 middle school students from Xuancheng, Hefei, and Huaibei cities in Anhui province, China. The self-report questionnaires included the Olweus Bully/Victim Questionnaire and Pittsburgh Sleep Quality Index. We used latent class analysis to identify the potential subgroups of bullying behavior. Logistic regression analysis was used to investigate the association between school bullying and sleep disorders.

Results

Active participants in bullying interactions, including the bullies and victims, reported higher levels of sleep disorders compared with the non-active participants [Bully: physical (aOR = 2.62), verbal (aOR = 1.73), relational (aOR = 1.80), and cyber (aOR = 2.08); Victim: physical (aOR = 2.42), verbal (aOR = 2.59), relational (aOR = 2.61), and cyber (aOR = 2.81)]. A dose-response relationship was observed between the number of school bullying types and sleep disorders. In the context of bullying roles, bully-victims had the highest risk of reporting sleep disorders (aOR = 3.07, 95% CI: 2.55-3.69). We identified four potential categories of school bullying behaviors: low involvement in bullying, verbal and relational victims, medium bully-victims, and high bully-victims, and the highest frequency of sleep disorders was observed in the high bully-victims group (aOR = 4.12, 95% CI: 2.94-5.76).

Conclusion

Our findings indicate a positive correlation between bullying roles and sleep disorders in early adolescents. Therefore, targeted intervention for sleep disorders should include an evaluation of bullying experiences.

More time awake after sleep onset is linked to reduced ventral striatum response to rewards in youth with anxiety

BACKGROUND

Poor sleep and anxiety disorders are highly comorbid in youth, and each predicts altered ventral striatum (VS) response to rewards, which may impact mental health risk. Contrasting evidence suggests previously reported negative associations between sleep health and VS response may be stronger or weaker in youth with anxiety, indicating sensitivity to win/loss information or blunted reward processing, respectively. We cross-sectionally examined the role of sleep in VS response to rewards among youth with anxiety versus a no-psychiatric-diagnosis comparison (ND) group. We expected a group*sleep interaction on VS response to rewards but did not hypothesize directionality.

METHODS

As part of the pretreatment battery for a randomized clinical trial, 74 youth with anxiety and 31 ND youth (ages 9-14 years; n = 55 female) completed a monetary reward task during fMRI. During the same pretreatment window, actigraphy and diary-estimated sleep were collected over 5 days, and participants and their parents each reported participants' total sleep problems. We examined group*sleep interactions on VS response to monetary rewards versus losses via three mixed linear models corresponding to actigraphy, diary, and questionnaires, respectively.

RESULTS

Each model indicated group*sleep interactions on VS response to rewards. Actigraphy and diary-estimated time awake after sleep onset predicted reduced VS response in youth with anxiety but not ND youth. Parent-reported sleep problems similarly interacted with group, but simple slopes were nonsignificant.

CONCLUSIONS

Wake after sleep onset was associated with blunted reward response in youth with anxiety. These data suggest a potential pathway through which sleep could contribute to perturbed reward function and reward-related psychopathology (e.g., depression) in youth with anxiety.

Comparison Between High School Youth and College Freshmen Toward Their Psychological Disorders Under the Influence of Sleep Hygiene During COVID-19 Pandemic

OBJECTIVE

Adolescents experience the critical period for physical and psychological growth. Few studies focus on the influence of sleep hygiene on the psychological health of adolescence aging from high school to freshmen year. Also, the influence from the COVID-19 pandemic has a public health significance.

METHODS

A total of 698 students from high schools and colleges were included in the manuscript, and a cross-sectional procedure was conducted, objective to make an epidemiological comparison of the social phobia/depression prevalence, and discuss the effects of potential determinants.

RESULTS

Psychological problems including social phobia and depression were prevalent especially among the high school students, with the female gender showing higher possibilities. Current results also indicated that the association between sleep status and the occurrence of social phobia is most obvious among high school students, while relatively higher MMR risks was found both for high school students showing symptoms of social phobia and college freshmen with depressive symptoms. Moreover, the interaction between social phobia and depression was obvious for both populations.

CONCLUSIONS

Psychological problems including social phobia symptoms and depression are more prevalent among the high school females when compared with their male and freshemen peers. Sgnificant influencial factors for the risk of psychological problems among 2 populations are different, but media multitasking status should be paid attention to for both.

Calling on All Child and Family Practitioners to Help Mitigate the Impacts of the Poor Behavioural Health of Children with Psychiatric Illness

Adolescents and children (aged 6 to 17+ years) admitted to inpatient psychiatry or intensive out-of-home mental health programs (formerly called residential mental health treatment centres) are among those with the most severe psychiatric illnesses. Moreover, these children also have very poor behavioural and biopsychosocial health including sleep deprivation, difficult relationships, problematic use of electronic devices, academic difficulty, poor school engagement, insufficient exercise and poor diets; all of these were noted before the pandemic. The pandemic has only increased the social isolation, poor health behaviours and mental health challenges for many children and adolescents. The poor behavioural and psychosocial health of those in their youth with psychiatric illnesses can exacerbate symptoms and can interfere with academic performance, development and good decision making; these biopsychosocial health behaviours are modifiable. All child and family practitioners including pediatricians, family physicians, nurses, social workers, psychologists and psychotherapists have an important role in fostering the behavioural and biopsychosocial health (i.e., sleep, positive relationships, electronic device use, exercise and diet) of all family members and especially children with psychiatric illness. Enacting biopsychosocial lifestyle interventions before or during childhood and adolescence may reduce the burden of mental illness.

Sleep Problems and Autism Impairments in a Large Community Sample of Children and Adolescents

Sleep problems are common in individuals with autism spectrum disorder (ASD). How sleep problems reflect specific ASD phenotypes is unclear. We studied whether sleep problems indexed functional impairment in a heterogeneous community sample of individuals with ASD. We analyzed 977 probands (233 females; age = 11.27 ± 4.13 years) from the Rhode Island Consortium for Autism Research and Treatment dataset, a unique public-private-academic collaboration involving all major points of service for families in Rhode Island. We found that individuals with a confirmed diagnosis of ASD were more likely to have sleep problems. However, across the whole sample and above and beyond a formal diagnosis, sleep problems were dimensionally associated with worse social impairment and poorer adaptive functioning. By using a large dataset reflective of the diversity of presentations in the community, this study underscores the importance of considering sleep problems in clinical practice to improve adaptive functioning in individuals with ASD.

Sleep Disturbance in Chinese College Students with Mental Health Problems: A Moderated Mediation Model

Sleep disturbance has an enormous impact on college students. Poor sleep is associated with low academic achievement, psychological distress and high health risk behaviors. College students with various mental health problems (e.g., anxiety and depression) are particularly at risk for sleep problems. The aim of the present study was to examine the impact of a wide range of internalizing/externalizing psychological problems on sleep disturbance. A total of 2134 Chinese college students (60.2% men) with mental health problems were selected as participants after completing the self-reported Chinese college student mental health screening scale. A web-based survey was used to assess a wide variety of internalizing/externalizing psychological problems and sleep disturbance. The results showed that hostility, somatic symptoms and obsessive-compulsive symptoms (OCS) were significantly associated with sleep disturbance. Somatic symptoms played a mediating role in the relationship between hostility and sleep disturbance. Moreover, the mediating effect was moderated by OCS, and a significant difference in the mediating effects was observed between low OCS and high OCS groups. Overall, our research findings indicate that a high level of OCS exacerbates the adverse effects of somatic symptoms on sleep disturbance, and suggests that assessment and improvement of hostility, somatic symptoms and OCS should be considered in facilitating better sleep among college students with mental health problems.

Biopsychosocial Attributes of Single-region and Multi-region Body Pain During Early Adolescence: Analysis of the ABCD Cohort

OBJECTIVES

Multi-region pain during adolescence is associated with a higher symptom burden and lower quality of life. The purpose of this study was to describe and compare the biopsychosocial attributes of single-region and multi-region pain among healthy young adolescents.

MATERIALS AND METHODS

We analyzed data from 10,320 children aged 10.6 to 14 years who self-reported pain in the Adolescent Brain and Cognitive Development Study. Pain was coded as single-region or multi-region based on body map data.

RESULTS

One in 5 young adolescents indicated recent multi-region pain. Sequential regression supported improved model fit when psychological and sociocultural factors were added to a biological model of pain; however, these models improved the classification of multi-region but not single-region pain. A significant interaction effect of sex and puberty remained constant across models with increased odds of pain at each advancing pubertal stage for both sexes compared with prepuberty, but no difference between girls and boys at late puberty (adjusted odds ratio [OR]=2.45 [1.72, 3.49] and adjusted OR=1.63 [1.20, 2.23], respectively). Psychological factors improved the classification of multi-region pain with significant effects of anxiety, somatic symptoms, and somnolence. Finally, compared with White and non-Hispanic children, Black and Hispanic children were less likely to report pain (adjusted OR=0.70 [0.61, 0.80]; adjusted OR=0.88 [0.78, 0.99], respectively) but had significantly higher pain interference when pain was present (adjusted OR=1.49 [1.29, 1.73] and adjusted OR=1.20 [1.06, 1.35], respectively).

DISCUSSION

Pain is a biopsychosocial phenomenon, but psychological and sociocultural features may be more relevant for multi-region compared with single-region pain during early adolescence.

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.

Co-occurring attention-deficit/hyperactivity disorder and anxiety disorders differentially affect males and females with autism

OBJECTIVE

To examine overlap and divergence of symptomatology in Autism Spectrum Disorder (ASD) with and without co-occurring Attention/Deficit Hyperactivity Disorder (ADHD) and/or Anxiety Disorder by age and sex.

METHOD

Participants included 25,078 individuals registered in the SPARK cohort, age 6-18 years. SPARK participation includes online consent and registration, as well as parent-reported ASD, ADHD, and Anxiety Disorder diagnoses, developmental, medical, and intervention history, and standardized rating scales. Individuals with ASD, ASD + ADHD, ASD + Anxiety, or ASD + ADHD + Anxiety were compared on measures assessing social communication, restricted and repetitive behaviors (RRBs), and motor functioning, and differences between male and female profiles were examined.

RESULTS

Significant differences in symptom presentation between females/males, school-age/adolescent individuals, and by co-occurring conditions (ASD/ADHD/Anxiety) are apparent, and the impact of co-occurring conditions differed by age and sex. Most notably, school-age femaleswith ASD without co-occurring conditions present with significantly fewer concerns about social communication skills and have better motor skills, but have more prominent RRBs as compared to same-aged males with ASD alone; co-occurring conditions were associated with increased social communication problems and motor concerns, most consistently for school-age females.

CONCLUSIONS

School-age females with ASD are at highest risk for underestimation of autism-related symptoms, including underestimation of symptoms beyond core ASD features (motor skills). Further, across ages, particular consideration should be given when probing for social communication symptoms, RRBs, and motor skills in females with ASD alone, as well as with co-occurring ADHD and/or Anxiety. For females with co-occurring symptoms and conditions, use of symptom-specific measures in lieu of omnibus measures should be considered.

A randomised controlled dismantling trial of sleep restriction therapies for chronic insomnia disorder in middle childhood: effects on sleep and anxiety, and possible contraindications

Sleep restriction therapies likely drive improvement in insomnia in middle childhood via increases in homeostatic sleep pressure (e.g., evening sleepiness). Increased evening sleepiness may also dampen comorbid anxiety symptoms; and reduced wakefulness in bed may reduce worry. However, sleep restriction therapies have never been evaluated as a standalone intervention in this population. The mechanism of action needs testing, as do effects on anxiety, and cognitive performance and parasomnias (possible contraindications). This randomised controlled trial evaluated the efficacy of two "doses" of sleep restriction therapy (sleep restriction therapy, bedtime restriction therapy), compared to a control condition (time in bed regularisation). A total of 61 children (mean [SD, range] age 9.1 [2.1, 6-14] years; 54% female) with chronic insomnia disorder received two weekly 60-min treatment sessions with a psychologist. Sleep, sleepiness, anxiety, worry, cognitive performance, and parasomnias were measured pre-treatment, across treatment, and at 4-weeks post-treatment. Both the sleep and bedtime restriction groups experienced reductions in total sleep time (d = 1.38-2.27) and increases in evening sleepiness (d = 1.01-1.47) during the 2-week treatment, and improvements in insomnia (i.e., sleep onset latency; d = 1.10-1.21), relative to the control group. All groups reported improved anxiety and worry, yet there were no differences between the control and restriction groups (all p > 0.658). Time in bed increased at the 1-month follow-up, and benefits to sleep and insomnia were maintained. There were no adverse effects on cognitive functioning (all p > 0.259), nor parasomnia occurrence (all p > 0.740). These results suggest that sleep restriction therapies are brief, yet effective, standalone interventions for insomnia in middle childhood, and improvements are likely due to increased sleepiness, not sleep regularisation.

Sleepy and Secluded: Sleep Disturbances are Associated With Connectedness in Early Adolescent Social Networks

Studies in adults suggest that sleep disturbances predict poorer socioemotional skills and impaired social interactions. However, little is known regarding how sleep disturbances are associated with social processes during adolescence, a period when both sleep neurobiology and social relationships are undergoing dramatic developmental changes. The current study examined associations among sleep disturbances and peer connectedness in a sample of middle-school students (N = 213, 11-15 years old, 57% female) using a social network approach. Findings suggested that youth with greater sleep disturbances reported having fewer social connections, were rated as a social connection by fewer peers, and were less likely to have reciprocated nominations, even after controlling for sociodemographic characteristics and mental health symptoms.

Sleep Duration Buffers The Effects of Adversity on Mental Health Among Recently Immigrated Latinx Adolescents

The rate of Latinx migration to the U.S. has risen rapidly over the last several decades. Recognizing that Latinx migrant youth are exposed to a high rate of adverse events and that sleep has potential buffering effects on mental health, the current study aimed to examine sleep duration as a moderator of the link between childhood adversity and emotional and behavioral symptoms among Latinx migrant youth. One hundred and twelve first-generation migrants of Latinx ethnicity (and 46 caregivers) participated in this study; the average age was 19 (SD = 2). Participants self-reported demographics: 59.8% of participants were male, with the racial breakdown as follows: 38.8% white, 6.1% black, 4.1% mixed race, and 51% marked "other." Data were collected from a public high school for immigrant youth in the Southwestern U.S. and included average sleep duration, Adverse Childhood Experiences; the Child PTSD Symptoms Scale and the Child Behavior Checklist. Findings indicated experiences of neglect in childhood were associated with youth-reported mental health symptoms, but this relation was significantly moderated by sleep duration such that the relation was weakened in the presence of high sleep duration. Both effects were statistically significant and of medium size. Caregiver reports supported the buffering effects of sleep; medium or large interactions between sleep and all three adversity variables (abuse, neglect, and household dysfunction) were noted in multivariate analyses. The current study takes an important first step in identifying that short sleep duration is prevalent among Central American immigrant youth. Findings suggest that sleep duration has important public health potential as a means of buffering the effects of childhood adversity on mental health in a vulnerable group.

Adolescent circadian patterns link with psychiatric problems: A multimodal approach

Circadian rhythms orchestrate brain function and mental wellbeing. We compared circadian patterns derived from continuous measurements of body temperature, sleep actigraphy and self-reported circadian preference in relation to different psychiatric disorders. 342 adolescents (70% females) aged 17.4y underwent M.I.N.I. psychiatric interviews, wore Ibutton 1922L skin temperature loggers (n = 281; 3 days), completed one-week GeneActiv Original actigraphy measurements (n = 306) and responded to Morningness-Eveningness Questionnaire (MEQ; n = 330). We derived circadian period length and amplitude from the temperature loggers. Actigraphy measures included sleep duration, midpoint, efficiency, and irregularity as well as Delayed Sleep Phase (DSP) characteristics (bedtime after 1 a.m. 3 times/week). M.I.N.I. psychiatric interviews suggested that 36% of participants had one or more psychiatric problem, with 21% suffering from comorbidity. Severe depression was associated with longer circadian period (p = 0.002). Suicidality was associated with later midpoint (p = 0.007) and more irregular sleep (p = 0.007). Those with agoraphobia slept longer (p = 0.013). Manic episodes and psychotic disorders were associated with irregular sleep (p-values <0.02). DSP was related to suicidality (p = 0.026), panic disorder (p = 0.022), and greater comorbidity (p = 0.026). Preference for eveningness was similarly related to higher prevalence of Generalized Anxiety Disorder (p = 0.014), social anxiety (p = 0.03), agoraphobia (p = 0.026), panic disorder (p = 0.004), suicidality (p = 0.018), severe depression (p < 0.001), and comorbidity (p < 0.001). Deviations in circadian rhythms were widely associated with psychiatric problems, whereas sleep duration was not. Especially suicidality linked with several markers of circadian disruption: later sleep midpoint, irregular sleep, and DSP characteristics. Longer circadian period length was associated with severe depression.

Sleep problems, sleep duration, and use of digital devices among primary school students in Japan

BACKGROUND

There is growing concern that screen time and media use in school-age children can negatively affect children's sleep. These negative effects are explained by three main underlying mechanisms: reduced sleep, time allocated for more media consumption; increased mental, emotional, or psychological stimulation by media content; and the effects of light emitted by digital devices on circadian rhythms and sleep physiology and arousal. In this study, we focused not only on sleep duration, but also on sleep problems. We conducted a large-scale survey to examine the relationship between excessive use of digital devices, Internet addictive behaviour, sleep duration, and sleep problems.

METHODS

We conducted a cross-sectional study of children enrolled in 20 public primary schools in Nagoya City, Japan. Children's parents/guardians completed a questionnaire including the brief sleep questionnaire for Japanese children which is a shortened version of the 'Children's Sleep Habits Questionnaire'. Logistic regression analyses were used to identify associations between sleep problems and grade, sex, weekday sleep time, weekend sleep time, ownership of digital devices, frequent checking of digital devices, use of digital devices for more than 4 hours per day, and Internet addiction.

RESULTS

In total, 8172 responses were received (91.6% response rate). After excluding incomplete responses, we analysed complete datasets for 6893 children with a mean age of 9.0 years. When adjusted for sex, grade, sleep duration on weekdays, and sleep duration on weekends, failure to control (odds ratio [OR] = 1.48; 95% confidence interval [CI]: 1.29-1.70; p < .001), more use than intended (OR = 1.27; 95% CI: 1.12-1.44; p < .001), and use to escape a dysphoric mood (OR = 1.30; 95% CI: 1.03-1.64; p = .027) were associated with children's sleep problems. A shorter weekday and a longer weekend sleep duration indicated a higher likelihood of sleep problems.

CONCLUSIONS

After adjusting for sleep duration, a relationship was found between the three Internet addictive behaviours and sleep problems, but not ownership of digital devices. Parents and teachers may need to address screen media-related sleep problems in children, as these problems may be influenced by psychological factors.

Prenatal tobacco and alcohol exposures and the risk of anxiety symptoms in young adulthood: A population-based cohort study

BACKGROUND

Epidemiological studies have linked prenatal tobacco and alcohol exposures to internalizing behaviours in children and adolescents with inconsistent findings. Dearth of epidemiological studies have investigated the associations with the risk of experiencing symptoms of anxiety in young adulthood.

METHODS

Study participants (N = 1190) were from the Raine Study, a population-based prospective birth cohort based in Perth, Western Australia. Data on prenatal tobacco and alcohol exposures were available for the first and third trimesters of pregnancy. Experiencing symptoms of anxiety in young adulthood at age 20 years was measured by a short form of the Depression Anxiety Stress Scale (DASS 21). Relative risk (RR) of experiencing symptoms of anxiety in young adulthood for prenatal tobacco and alcohol exposures were estimated with log binomial regression.

RESULTS

After adjusting for potential confounders, we observed increased risks of experiencing symptoms of anxiety in young adults exposed to prenatal tobacco in the first trimester [RR = 1.52, 95% CI: 1.12-2.06, p-value < 0.01] and third trimester [RR = 1.53, 95% CI: 1.10-2.13, p-value  = 0.02]. However, we found insufficient statistical evidence for an association between first trimester [RR = 1.01, 95% CI: 0.76-1.22, p-value = 0.90] and third trimester [RR = 1.03, 95% CI: 0.80-1.34, p-value = 0.91] prenatal exposure to alcohol and the risk of experiencing symptoms of anxiety in young adults. There was a dose response association between prenatal tobacco exposure and increasing anxiety symptoms in offspring.

CONCLUSION

The findings of this study suggest that an association between prenatal tobacco exposure and risk of anxiety symptoms remains apparent into young adulthood.

Adolescents' sleep and adjustment: Reciprocal effects

Reciprocal relations between sleep and adjustment were investigated. Participants included 246 adolescents (M = 15.80 years; 67.5% White, 32.5% Black/African American; 53% female, 47% male) at Time 1 (data collected 2012-2013), 227 at Time 2 (M = 16.78 years) and 215 at Time 3 (M = 17.70 years). Sleep-wake variables were measured with self-reports (sleepiness) and actigraphy (average sleep minutes and efficiency, variability in sleep minutes and efficiency). Adolescents reported on depression and anxiety symptoms, and parents reported on externalizing problems. Greater variability in sleep duration and efficiency as well as sleepiness predicted adjustment problems (range of R² : 36%-60%). Reciprocal relations were supported mostly for sleepiness (range of R² : 16%-32%). Results help understand bidirectional relations between sleep and adjustment.

Out-of-home placement, sleep problems, and later mental health and crime: A prospective investigation

Previous research suggests that out-of-home placement experiences increase the risk for mental health problems and criminal involvement. However, few studies have examined the mechanisms whereby out-of-home placement increases the risk for these outcomes. The present study examines whether sleep problems in part explain the relationship between childhood placement experiences and depression and anxiety and criminal arrests in adulthood. Data are from a prospective longitudinal study of 531 children with documented cases of childhood maltreatment (14% with no out-of-home placement, 68% placed solely for abuse and/or neglect, and 18% placed for maltreatment and delinquency) who were followed up into adulthood. Cases are from 1967 to 1971 from a metropolitan county in the Midwest. Sleep problems were assessed in young adulthood (M_age = 29 years). Depression and anxiety symptoms and arrest records were assessed in middle adulthood (M_age = 40 years). Structural equation modeling was used to test hypotheses. Both types of out-of-home placement experiences (for maltreatment only and for maltreatment and delinquency) predicted more sleep problems in adulthood across all models. Sleep problems in young adulthood predicted higher levels of anxiety and depression in middle adulthood, but not criminal arrests. Sleep problems mediated the relationship between placement only and internalizing symptoms and results differed for male, female, White, and Black individuals examined separately. Using court-substantiated cases of childhood abuse and neglect, this study demonstrates the long-term negative consequences of out-of-home placement experiences for sleep problems and anxiety and depression in adulthood. More attention is needed to insure adequate sleep for maltreated children. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Associations between Sleep and Mental Health in Adolescents: Results from the UK Millennium Cohort Study

(1) Background: There is a growing interest in investigating the relationship between sleep and mental health development in adolescents. This study aims to further investigate this relationship by identifying the specific associations between several sleep problems in adolescents and several mental health areas, and the role of gender in these associations. (2) Methods: Data from the Millennium cohort survey containing 11,553 individuals at 13–14 years old was included. Nighttime sleep duration and bedtime during weekdays and weekends, night awakening frequency, and sleep onset latency were assessed using self-reported questionnaires. Affective symptom and emotional and behavioural problems were examined with self-reported questionnaires. (3) Results: Regression analyses and path analysis models suggested that frequent night awakening was associated with all the outcomes, and hyperactivity/inattention was the outcome that presented a higher number of significant associations with sleep patterns. Long sleep onset latency and late bedtime at school days were associated with higher risk of emotional and behavioural difficulties. Further, poor sleep seems to manifest more externally in males, while more internally in females. (4) Conclusions: Specific sleep problems should be considered when assessing mental health in adolescence, which would allow more targeted prevention and intervention strategies. Further, special attention should be given to gender differences when addressing sleep and mental health.

Sleep in the time of COVID-19: findings from 17000 school-aged children and adolescents in the UK during the first national lockdown

STUDY OBJECTIVES

Sleep is essential to young people's wellbeing, yet may be constricted by the adolescent delayed sleep phase coupled with school start times. COVID-19 restrictions caused major disruptions to everyday routines, including partial school closures. We set out to understand changes in students' self-reported sleep quality, and associations with mental wellbeing and interpersonal functioning, during these restrictions.

METHODS

The OxWell school survey-a cross-sectional online survey-collected data from 18 642 children and adolescents (aged 8-19 years, 60% female, school year 4-13) from 230 schools in southern England, in June-July 2020. Participants completed self-report measures of the impact of COVID-19 restrictions on sleep quality, happiness, and social relationships. Sleep timing was compared with data collected from 4222 young people in 2019.

RESULTS

Females and older adolescents were more likely to report deteriorations in sleep during the national lockdown. Regression analysis revealed that changes in happiness (β = .34) and how well students were getting on with others in their household (β = .07) predicted change in sleep quality. Students' bedtimes and wake times were later, and sleep duration was longer in 2020 compared to the 2019 survey. Secondary school students reported the greatest differences, especially later wake times.

CONCLUSIONS

During COVID-19 restrictions, sleep patterns consistent with adolescent delayed sleep phase were observed, with longer sleep times for secondary school students in particular. Perceived deteriorations in sleep quality were associated with reductions in happiness and interpersonal functioning, highlighting the importance of including sleep measures in adolescent wellbeing research.

Asociación entre alteraciones en el sueño y problemas de salud mental en los estudiantes de Medicina durante la pandemia de la COVID-19

Introduction

Medical students are a population vulnerable to poor sleep quality and sleep deprivation; these problems were accentuated during the COVID-19 pandemic. The objective was to evaluate the association between sleep disturbances and the presence of depression and anxiety in medical students during the pandemic.

Materials and methods

Cross-sectional, analytical study in medical students of a private university in Peru. Data were collected from May 22 to June 14, 2020, after 3 months of mandatory social isolation. The Patient Health Questionnaire (PHQ-9; ≥ 10), the Generalized Anxiety Disorder (GAD-7; ≥ 10) scale and the Insomnia Severity Index (ISI; ≥ 8) were used to assess depression, anxiety and insomnia, respectively. Poisson regressions with robust variance were used to calculate prevalence ratios.

Results

The prevalence of depression, anxiety and insomnia was 28.5%, 29.5% and 60.1% respectively. It was found that those who had short sleep (RPa: 1.40, CI: 1.05-1.87, p: 0.024), who slept after 2:00 hours (RPa: 2.24, CI: 1.31-3.83, p: 0.003) and who presented insomnia (RPa: 7.12, CI: 3.70-13.73, p: < 0.001) had a higher prevalence of anxiety. Likewise, those who slept after 2:00 hours (RPa: 2.13, CI: 1.24-3.64, p: 0.006) and those who presented insomnia (RP: 8.82, CI: 4.17-18.68, p: < 0.001) had a higher prevalence of depression.

Conclusions

Short sleep, bedtime and insomnia are factors associated with the prevalence of depression and anxiety.

Methylmercury plus Ethanol Exposure: How Much Does This Combination Affect Emotionality?

Mercury is a heavy metal found in organic and inorganic forms that represents an important toxicant with impact on human health. Mercury can be released in the environment by natural phenoms (i.e., volcanic eruptions), industrial products, waste, or anthropogenic actions (i.e., mining activity). Evidence has pointed to mercury exposure inducing neurological damages related to emotional disturbance, such as anxiety, depression, and insomnia. The mechanisms that underlie these emotional disorders remain poorly understood, although an important role of glutamatergic pathways, alterations in HPA axis, and disturbance in activity of monoamines have been suggested. Ethanol (EtOH) is a psychoactive substance consumed worldwide that induces emotional alterations that have been strongly investigated, and shares common pathophysiological mechanisms with mercury. Concomitant mercury and EtOH intoxication occur in several regions of the world, specially by communities that consume seafood and fish as the principal product of nutrition (i.e., Amazon region). Such affront appears to be more deleterious in critical periods of life, such as the prenatal and adolescence period. Thus, this review aimed to discuss the cellular and behavioral changes displayed by the mercury plus EtOH exposure during adolescence, focused on emotional disorders, to answer the question of whether mercury plus EtOH exposure intensifies depression, anxiety, and insomnia observed by the toxicants in isolation.
