Sleep loss and emotion: A systematic review and meta-analysis of over 50 years of experimental research.

In a largely sleep-deprived society, quantifying the effects of sleep loss on emotion is critical for promoting psychological health. This preregistered systematic review and meta-analysis quantified the effects of various forms of sleep loss on multiple aspects of emotional experiences. Eligible studies used experimental reductions of sleep via total sleep deprivation, partial sleep restriction, or sleep fragmentation in healthy populations to examine effects on positive affect, negative affect, general mood disturbances, emotional reactivity, anxiety symptoms, and/or depressive symptoms. In total, 1,338 effect sizes across 154 studies were included (N = 5,717; participant age range = 7-79 years). Random effects models were conducted, and all forms of sleep loss resulted in reduced positive affect (standardized mean difference [SMD] = -0.27 to -1.14), increased anxiety symptoms (SMD = 0.57-0.63), and blunted arousal in response to emotional stimuli (SMD = -0.20 to -0.53). Findings for negative affect, reports of emotional valence in response to emotional stimuli, and depressive symptoms were mixed and depended on the type of sleep loss. Nonlinear effects for the amount of sleep loss as well as differences based on the stage of sleep restricted (i.e., rapid eye movement sleep or slow-wave sleep) were also detected. This study represents the most comprehensive quantitative synthesis of experimental sleep and emotion research to date and provides strong evidence that periods of extended wakefulness, shortened sleep duration, and/or nighttime awakenings adversely influence human emotional functioning. Findings provide an integrative foundation for future research on sleep and emotion and elucidate the precise ways that inadequate sleep may impact our daytime emotional lives.

Preliminary exploration of a multidimensional sleep health composite in adolescent females with frequent migraine.

OBJECTIVE: This observational study aimed to: (i) describe and explore preliminary psychometric properties of a multidimensional sleep health composite score in adolescent females with frequent migraine; and (ii) examine associations between the composite score, headache characteristics, and emotional health. BACKGROUND: Sleep health is a multidimensional construct comprised of various dimensions of sleep and circadian functioning, including Regularity, Satisfaction, Alertness, Timing, Efficiency, and Duration (Ru-SATED framework). The Ru-SATED sleep health composite score may provide a holistic perspective of sleep among adolescents with frequent migraine in the context of neurobiological and psychosocial impacts on sleep unique to this developmental period. METHODS: In all, 60 female adolescents (aged 12-18 years) with high-frequency episodic or chronic migraine completed wrist-worn actigraphy for 10 days and concurrent daily electronic surveys assessing headache, sleep, and emotional health. A sleep health composite score was derived from empirically supported "healthy" versus "unhealthy" ratings on the six Ru-SATED sleep dimensions. RESULTS: Half of participants (27/54 [50%]) had a composite score ≥4 (i.e., at least four of the six dimensions rated as poor). Convergent validity of the composite score was acceptable (rs = 0.30-0.56, all p < 0.05). Internal consistency among the dimensions was low (α = 0.45). Multivariate multiple regression models indicated that worse sleep health was associated with greater headache-related disability (B = 0.71, p = 0.018) and anxiety (B = 0.59, p = 0.010), and trended toward significance for sadness (B = 0.35, p = 0.052). The composite score was not significantly associated with headache frequency or severity. CONCLUSIONS: A multidimensional sleep health composite score may provide an alternative, more comprehensive picture of sleep disturbance among adolescent females with frequent migraine. Larger studies are needed to examine psychometric properties more rigorously and further explore the composite score as a potentially unique predictor of headache outcomes.

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

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

Cognitive-behavioral therapy and exercise training in adolescent females with elevated depression symptoms and at-risk for type 2 diabetes: Protocol for a randomized controlled trial.

BACKGROUND: Adolescent-onset type 2 diabetes (T2D) is a major public health concern of growing proportions. Prevention, therefore, is critical. Unfortunately, standard-of-care treatment for T2D prevention (e.g., exercise training) show insufficient effectiveness and do not address key modifiable barriers (e.g., depression symptoms) to exercise engagement. Depression symptoms are associated with both poorer physical fitness and greater insulin resistance, the key risk factor in adolescent-onset T2D. Thus, a targeted prevention approach that addresses depression symptoms in combination with exercise training may offer a novel approach to mitigating T2D risk. METHODS: This manuscript describes the design and study protocol for a multi-site, four-arm randomized controlled trial comparing the efficacy of group cognitive-behavioral therapy, group exercise training, and their combinations for the targeted prevention of worsening insulin resistance in N = 300 adolescent females at-risk for T2D with BMI ≥85th percentile and elevated depression symptoms. All four intervention arms will run in parallel and meet weekly for 1 h per week for 6-week to 6-week segments (12 weeks total). Outcomes are assessed at baseline, 6-week mid-treatment, 12-week follow-up, and 1-year follow-up. RESULTS: The primary outcome is insulin resistance. Key secondary outcomes include insulin sensitivity, cardiorespiratory fitness, physical activity, depression symptoms, and body measurements. CONCLUSION: Study findings will guide the ideal sequencing of two brief T2D prevention interventions for ameliorating the course of insulin resistance and lessening T2D risk in vulnerable adolescents. These interventions will likely be cost-effective and scalable for dissemination, having the potential for significant public health impact on communities at risk for T2D.

Outpatient Approach to Resistant and Refractory Migraine in Children and Adolescents: a Narrative Review.

PURPOSE OF REVIEW: Migraine is one of the top reasons for consulting a pediatric neurologist. Although the majority of children and adolescents who receive evidence-based first-line interventions for migraine will improve substantially, a subset of patients develop resistant or refractory migraine. RECENT FINDINGS: In this review, we summarize the level of evidence for a variety of acute and preventive treatment options to consider in children and adolescents with resistant or refractory migraine. We describe the level of evidence for interventional procedures (onabotulinumtoxinA injections, greater occipital and other nerve blocks), neuromodulation (single-pulse transcranial magnetic stimulation, external trigeminal nerve stimulation, remote electrical neuromodulation, and non-invasive vagal nerve stimulation), calcitonin gene-related peptide (CGRP) pathway antagonists (anti-CGRP monoclonal antibodies and gepants), psychological therapies, and manual therapies (acupuncture, craniosacral therapy, massage and physical therapy, and spinal manipulation).

Headache and Sleep Disturbances in the Pediatric Population.

The relationship between sleep disturbances and headaches in the pediatric population is bidirectional. Common underlying molecular mechanisms of sleep and headaches have been speculated to explain the clinical connection. We will summarize various sleep disturbances and their known relationships to headache, focusing on the pediatric population. Careful recognition and assessment of sleep disturbances in patients with headache is critical and may help guide treatment. First line therapies for sleep disturbances consist of behavioral approaches, though surgical and pharmacologic strategies are utilized in particular circumstances.

Perfectly Tired: Perfectionism and Sleep in Adolescents With Chronic Pain.

OBJECTIVE: Conceptual links between perfectionism and chronic pain have been proposed yet minimal empirical data exists. Poor sleep is associated with high levels of perfectionism and is common among youth with chronic pain. This study explores associations between perfectionism and sleep quality in adolescents with chronic pain while considering levels of functional disability. METHODS: Adolescents (ages 12-18) with chronic pain (N = 423) completed baseline measures of self-oriented perfectionism (SOP), socially prescribed perfectionism (SPP), sleep quality, and functional disability as part of routine clinical care at an outpatient chronic pain clinic and a pain rehabilitation day treatment program. Multivariate multiple regression assessed associations between perfectionism (SOP and SPP) and sleep (falling asleep/reinitiating sleep, returning to wakefulness, and going to bed). Two moderation models explored how relations between perfectionism (SOP and SPP) and sleep quality (total score) varied depending on level of functional disability. All analyses controlled for clinic setting. RESULTS: Results indicated SPP was associated with more difficulties across all sleep subdomains in adolescents with chronic pain, while SOP was unrelated to sleep quality. Associations between perfectionism and sleep quality were dependent on functional disability; perfectionism was most strongly associated with worse sleep quality for adolescents with less functional disability. CONCLUSIONS: This study highlights the relationship between perfectionism and sleep quality in adolescents with chronic pain and suggests that perfectionistic youth with less disability are at the greatest risk for sleep problems. Longitudinal research is needed to understand how perfectionism, sleep, and disability interact over time in youth with chronic pain.

The intersection of COVID-19, school, and headaches: Problems and solutions.

OBJECTIVE: To equip clinicians with recommendations specific to concerns related to the novel coronavirus disease 2019 (COVID-19), which impact the physical, emotional, and social health of youth with headache disorders. BACKGROUND: COVID-19 has affected societies on a global scale including children and youth with chronic headache disorders. Many concerns are predicted to arise in the 2020-2021 school year, whether classes are conducted in-person or virtually. METHODS: Clinical impressions were combined with a review of the literature, although limited due to the recent nature of this issue. RESULTS: We describe recommendations to support caregivers and youth as they face changes expected with the return to school in the fall of 2020. CONCLUSION: Although there are significant concerns for caregivers and youth with migraine given the context of changes related to the pandemic, there are many recommendations that can help minimize exacerbations of the physical, emotional, and social health of youth with chronic migraine.

An integrated sleep and anxiety intervention for anxious children: A pilot randomized controlled trial.

Sleep-related complaints hold complex reciprocal relationships with anxiety and are a pervasive, distressing feature of childhood generalized anxiety disorders (GAD). Although evidence suggests purely anxiety-focused treatments reduce some sleep problems of anxious children, interventions that directly target both anxiety and sleep might produce superior outcomes in both domains. Targeted Behavioral Therapy (TBT), developed for co-morbid sleep and anxiety problems, demonstrated initial efficacy in a small case series but has not been directly compared to anxiety-focused treatment. The current pilot study used a randomized controlled design to compare TBT to "gold standard" cognitive-behavioral therapy (CBT) for anxiety among n = 20 children (ages 6-12) with primary GAD. Multi-informant measures of anxiety and sleep (including actigraphy) were obtained at baseline, post-treatment, and 6-month follow-up. Results indicated significant improvements (based on moderate to large effect sizes) in anxiety and subjective sleep in both treatment groups at post-treatment. Improvements were maintained at 6-month follow-up. Objective sleep onset latency also decreased marginally for both groups at post-treatment (based on small effect size). Findings provide preliminary support for the feasibility and potential utility of anxiety-focused interventions for improving some sleep-related problems among anxious youth. Future studies including large samples are needed.

Psychosocial considerations and recommendations for care of pediatric patients on dialysis.

Dialysis treatment has evolved to enable children to live longer and transition to adulthood. Thus, the focus of care shifts to a consideration of pediatric patients' quality of life and psychosocial functioning across childhood, adolescence, and young adulthood. Despite well-documented concerns in various domains (including depression/anxiety, self-esteem and social functioning, behavior problems, and academic and cognitive functioning), limited literature exists regarding psychosocial guidelines for children and adolescents undergoing dialysis. This article aims to address this gap by providing a review of the pediatric literature examining psychosocial functioning in patients treated with dialysis, as well as recommendations for specific psychosocial concerns. Overall recommendations for care include screening for anxiety and depression, referral to pediatric psychologists for evidence-based intervention, utilization of child life specialists, opportunities to promote social functioning, neuropsychological evaluation and school programming, ongoing support in preparing for transition to adult care, and periodic measure of quality of life. Together, these suggestions promote a holistic approach to patient-centered care by supporting both physical and psychosocial well-being.

The Impact of Sleep on Disability and School Functioning: Results From a Tertiary Pediatric Headache Center.

Pediatric headache patients often experience significant sleep disturbance, which may be a risk factor for poor physical, academic, and emotional functioning, including increased anxiety/fear. The current retrospective cohort study of a clinical sample of youth with persistent headache aimed to examine the impact of sleep on functional outcomes and to explore pain-related fear as a mediator of the association between sleep problems and functioning. A total of 109 youth (aged 7-17 years) with persistent headache presenting to a tertiary pediatric headache center (and their parents) completed measures of sleep problems, fear of pain, functional disability, and school functioning at the time of an initial evaluation and 6 months later. After controlling for age and headache frequency and severity, linear regression analyses indicated that increased sleep problems at baseline were associated with increased functional disability and poorer school functioning at baseline (ß = 0.28, P = .01; ß = -0.42, P < .001, respectively). Poor sleep at baseline was associated with poorer school functioning (but not functional disability) at follow-up (ß = -0.25, P = .02). Mediation models demonstrated an indirect mediating effect of pain-related fear on the association between baseline sleep problems and follow-up functional disability (ß = 0.06, 95% confidence interval 0.01, 0.15) and between baseline sleep problems and follow-up school functioning (ß = -0.06, 95% confidence interval -0.13, -0.004). Sleep disturbance in youth with headache may be a risk factor for poor functional outcomes, both concurrently and over time, and may be explained partially through pain-related fear. Given the frequency with which pediatric headache patients experience co-occurring sleep problems, sleep should be thoroughly assessed and considered as a potential early treatment target.

Parent Factors are Associated With Pain and Activity Limitations in Youth With Acute Musculoskeletal Pain: A Cohort Study.

OBJECTIVES: Biopsychosocial models emphasize the influence of parent/family factors on pediatric chronic pain. Little is known about how parent factors differ across the acute to chronic pain continuum, or contribute to youths' pain experience in the acute pain period. The purpose of the study was to describe parent factors in youth with acute musculoskeletal pain (n=84) compared with youth with chronic pain (n=60) and youth without pain (n=61). Further, within the acute pain sample, we tested parent factors as predictors of child pain characteristics, as well as the moderating role of child sex on associations. METHODS: Participants were 205 youth (age, 10 to 17) and one biological parent per child. Children reported on their own pain and activity limitations. Parents reported on their own chronic pain, somatization, and protective pain responses. RESULTS: Parents of youth with acute pain had higher prevalence of chronic pain and greater somatization than parents of youth without pain. Parents of youth with acute and chronic pain did not differ. Linear regressions within the acute pain sample revealed presence of parent chronic pain and protective behavior were associated with child pain. Moreover, parent somatization was associated with child activity limitations. Within the acute pain sample, associations between parent protectiveness and child pain were moderated by child sex, with relationships stronger for female children. DISCUSSION: Findings highlight the importance of parent factors on pain experiences of youth with acute musculoskeletal pain. Future longitudinal research can elucidate temporal associations that underlie how parent factors may impact transition from acute to chronic pain.

Co-Sleeping among School-Aged Anxious and Non-Anxious Children: Associations with Sleep Variability and Timing.

Little is known about the co-sleeping behaviors of school-aged children, particularly among anxious youth who commonly present for the treatment of sleep problems. The current study examined the occurrence of co-sleeping in both healthy and clinically anxious children and its associated sleep patterns. A total of 113 children (ages 6-12), 75 with primary generalized anxiety disorder and 38 healthy controls, participated along with their primary caregiver. Families completed structured diagnostic assessments, and parents reported on their child's co-sleeping behaviors and anxiety severity. Children provided reports of anxiety severity and completed one week of wrist-based actigraphy to assess objective sleep patterns. A significantly greater proportion of anxious youth compared to healthy children co-slept, and greater anxiety severity was related to more frequent co-sleeping. Co-sleeping in anxious youth was associated with a delay in sleep timing and with greater sleep variability (i.e., more variable nightly sleep duration). All analyses controlled for child age, race/ethnicity, family income, and parental marital status. Co-sleeping is highly common in anxious school-aged children, with more than 1 in 3 found to co-sleep at least sometimes (2-4 times a week). Co-sleeping was even more common for youth with greater anxiety severity. Increased dependence on others to initiate and maintain sleep may contribute to poorer sleep in this population via shifted schedules and more variable sleep patterns.

Pain Acceptance as a Predictor of Medical Utilization and School Absenteeism in Adolescents With Chronic Pain.

Objective: Identifying factors contributing to high medical utilization and productivity loss is important, given the high cost of pediatric chronic pain. The current study examined chronic pain acceptance as a predictor of medical utilization and school absenteeism in adolescents with chronic pain. Methods: In all, 122 adolescents (aged 12-21 years) with chronic pain and their parents/guardians completed questionnaires assessing medical visits (past 6 months), medication usage, and number of school absences (past month). Homebound school status was also reported. Adolescents completed the Chronic Pain Acceptance Questionnaire and pain intensity ratings, and underwent a diagnostic psychological evaluation. Results: Multivariate generalized linear model analyses indicated lower pain acceptance predicted increased inpatient hospitalizations and higher number of opioid and nonopioid prescription medications, controlling for pain intensity, age, and sex. Pain acceptance was not associated with outpatient consultations or number of nonprescription medications. Exploratory moderation analyses indicated lower pain acceptance significantly predicted increased emergency department visits and inpatient hospitalizations for patients diagnosed with an internalizing psychological disorder. Patients in homebound schooling reported low pain acceptance and for those in school full-time, linear regression indicated lower pain acceptance significantly predicted higher number of school absences. Conclusions: Findings suggest that lower pain acceptance contributes to the use of higher-level medical care (especially for adolescents with internalizing disorders) and increased productivity loss owing to school absences or homebound school status. Clinical implications exist for recommending acceptance-based interventions for pain acceptance promotion and continued development of cost-effective, easily disseminated acceptance-based therapy modules to curb the economic burden of chronic pain.

Examination of the Intolerance of Uncertainty Construct in Youth With Generalized Anxiety Disorder.

Intolerance of uncertainty (IU) is a dispositional characteristic reflecting negative cognitive, behavioral, and emotional reactivity in response to events or situations that are uncertain. Although closely associated with a generalized anxiety disorder (GAD) diagnosis in adulthood, IU has received little attention in youth. The goal of this study was to examine the construct in children with GAD and nonanxious children, including its incremental validity in predicting GAD severity and worry beyond anxiety. Ninety-eight children 6 to 11 years of age (51% male; 57% Caucasian) were assessed. The sample included 24 with a GAD diagnosis only (i.e., pure GAD), 36 with GAD plus at least one other disorder (i.e., comorbid GAD), and 38 healthy control children. Clinician, parent, and child reports of IU, anxiety, worry, and GAD severity were collected. Significant differences in levels of IU were found across all three groups; the highest levels in children with comorbid GAD, followed by children with pure GAD, and healthy controls. IU significantly contributed to worry but not GAD severity beyond the effects of anxiety. A significantly larger proportion of self-reported IU data were missing for younger (e.g., 6-8 years) as compared to older children, raising question about the validity of the construct in younger children. Overall findings suggest that IU is not specific to a GAD diagnosis in childhood. IU may instead serve as a broad cognitive risk factor for more severe (e.g., comorbid) forms of affective psychopathology. Future directions for research, including developmental considerations, are discussed.

Neural changes with attention bias modification for anxiety: a randomized trial.

Attention bias modification (ABM) procedures typically reduce anxiety symptoms, yet little is known about the neural changes associated with this behavioral treatment. Healthy adults with high social anxiety symptoms (n = 53) were randomized to receive either active or placebo ABM. Unlike placebo ABM, active ABM aimed to train individuals' attention away from threat. Using the dot-probe task, threat-related attention bias was measured during magnetic resonance imaging before and after acute and extended training over 4 weeks. A subset of participants completed all procedures (n = 30, 15 per group). Group differences in neural activation were identified using standard analyses. Linear regression tested predictive factors of symptom reduction (i.e., training group, baseline indices of threat bias). The active and placebo groups exhibited different patterns of right and left amygdala activation with training. Across all participants irrespective of group, individuals with greater left amygdala activation in the threat-bias contrast prior to training exhibited greater symptom reduction. After accounting for baseline amygdala activation, greater symptom reduction was associated with assignment to the active training group. Greater left amygdala activation at baseline predicted reductions in social anxiety symptoms following ABM. Further research is needed to clarify brain-behavior mechanisms associated with ABM training.

Targeted Behavioral Therapy for childhood generalized anxiety disorder: a time-series analysis of changes in anxiety and sleep.

This study examined the efficacy of Targeted Behavioral Therapy (TBT), a newly developed intervention targeting features of childhood generalized anxiety disorder (GAD). Using a time-series design, 4 children (7-12 years) with primary GAD were treated with TBT, which includes sleep improvement strategies, systematic desensitization for reducing intolerance of uncertainty, and in vivo exposures for anxiety. Diagnostic interviews and questionnaires were administered at baseline, post-treatment and 3 months follow-up. Anxiety symptoms and sleep characteristics/problems were rated weekly during a 4-week baseline and 14-weeks of treatment. Two children remitted at post-treatment and no child had a GAD diagnosis at follow-up. Child but not parent report revealed improvements in both worry and sleep. Despite improvements from pre- to post-assessment, considerable symptom fluctuation observed during the baseline period preclude conclusion that symptom changes are specifically attributable to the course of treatment. Overall, preliminary support is provided for the efficacy of TBT for childhood GAD.

Training-associated changes and stability of attention bias in youth: Implications for Attention Bias Modification Treatment for pediatric anxiety.

Attention Bias Modification Treatment (ABMT), an emerging treatment for anxiety disorders, is thought to modify underlying, stable patterns of attention. Therefore, ABMT research should take into account the impact of attention bias stability on attention training response, especially in pediatric populations. ABMT research typically relies on the dot-probe task, where individuals detect a probe following an emotional-neutral stimulus pair. The current research presents two dot-probe experiments relevant to ABMT and attention-bias stability. In Experiment 1, anxious youth receiving 8-weeks of cognitive-behavioral therapy (CBT) were randomly assigned to ABMT that trains attention towards happy faces (n=18) or placebo (n=18). Two additional comparison groups, anxious youth receiving only CBT (n=17) and healthy comparison youth (n=16), were studied. Active attention training towards happy faces did not augment clinician-rated response to CBT; however, individuals receiving training exhibited reductions on self-report measures of anxiety earlier than individuals receiving CBT only. In Experiment 2, healthy youth (n=12) completed a dot-probe task twice while undergoing functional magnetic resonance imaging. Intra-class correlation demonstrated stability of neural activation in response to attention bias in the ventrolateral prefrontal cortex and amygdala. Together, these two studies investigate the ways in which attention-bias stability may impact future work on ABMT.
