The prospective relationship between sleep problems and suicidal behavior in the National Longitudinal Study of Adolescent Health

Sleep disturbances and psychological well-being among military medical doctors of the Swiss Armed Forces: study protocol, rationale and development of a cross-sectional and longitudinal interventional study

Background

Compared to civilians and non-medical personnel, military medical doctors are at increased risk for sleep disturbances and impaired psychological well-being. Despite their responsibility and workload, no research has examined sleep disturbances and psychological well-being among the medical doctors (MDs) of the Swiss Armed Forces (SAF). Thus, the aims of the proposed study are (1) to conduct a cross-sectional study (labeled 'Survey-Study 1') of sleep disturbances and psychological well-being among MDs of the SAF; (2) to identify MDs who report sleep disturbances (insomnia severity index >8), along with low psychological well-being such as symptoms of depression, anxiety and stress, but also emotion regulation, concentration, social life, strengths and difficulties, and mental toughness both in the private/professional and military context and (3) to offer those MDs with sleep disturbances an evidence-based and standardized online interventional group program of cognitive behavioral therapy for insomnia (eCBTi) over a time lapse of 6 weeks (labeled 'Intervention-Study 2').

Method

All MDs serving in the SAF (N = 480) will be contacted via the SAF-secured communication system to participate in a cross-sectional survey of sleep disturbances and psychological well-being ('Survey-Study 1'). Those who consent will be provided a link to a secure online survey that assesses sleep disturbances and psychological well-being (depression, anxiety, stress, coping), including current working conditions, job-related quality of life, mental toughness, social context, family/couple functioning, substance use, and physical activity patterns. Baseline data will be screened to identify those MDs who report sleep disturbances (insomnia severity index >8); they will be re-contacted, consented, and randomly assigned either to the eCBTi or the active control condition (ACC) ('Intervention-Study 2'). Individuals in the intervention condition will participate in an online standardized and evidence-based group intervention program of cognitive behavioral therapy for insomnia (eCBTi; once the week for six consecutive weeks; 60-70 min duration/session). Participants in the ACC will participate in an online group counseling (once the week for six consecutive weeks; 60-70 min duration/session), though, the ACC is not intended as a bona fide psychotherapeutic intervention. At the beginning of the intervention (baseline), at week 3, and at week 6 (post-intervention) participants complete a series of self-rating questionnaires as for the Survey-Study 1, though with additional questionnaires covering sleep-related cognitions, experiential avoidance, and dimensions of self-awareness.

Expected outcomes

Survey-Study 1: We expect to describe the prevalence rates of, and the associations between sleep disturbances (insomnia (sleep quality); sleep onset latency (SOL); awakenings after sleep onset (WASO)) and psychological well-being among MDs of the SAF; we further expect to identify specific dimensions of psychological well-being, which might be rather associated or non-associated with sleep disturbances.Intervention-Study 2: We expect several significant condition-by-time-interactions. Such that participants in the eCBTi will report significantly greater improvement in sleep disturbances, symptoms of depression, anxiety, stress reduction both at work and at home (family related stress), and an improvement in the overall quality of life as compared to the ACC over the period of the study.

Conclusion

The study offers the opportunity to understand the prevalence of sleep disturbances, including factors of psychological well-being among MDs of the SAF. Further, based on the results of the Intervention-Study 2, and if supported, eCBTi may be a promising method to address sleep disturbances and psychological well-being among the specific context of MDs in the SAF.

How to survive the long night? Longitudinal relationship between sleep problems and suicidal behavior among adolescents: The serial mediating roles of negative emotion, self-control, and nonsuicidal self-injury

OBJECTIVE

Sleep problems are a significant risk factor for identifying and preventing suicidal involvement among adolescents. However, there is limited evidence to assess the underlying mechanisms between them. This study investigated the longitudinal relationship between sleep problems and suicidal behavior and examined whether this relationship was moderated by negative emotions, low self-control, and nonsuicidal self-injury (NSSI).

METHODS

From December 2020 onward, we assessed 1214 Chinese secondary school adolescents (60.7% were boys, aged 13-19 years) three times, 6 months apart.

RESULTS

In the direct effects model, sleep problems were found to have a positive impact on adolescent suicidal behavior. In the indirect effects model, we observed that sleep problems were associated with an elevated risk of suicidal behavior through several pathways: one-mediator path of negative emotions, low self-control, and NSSI, respectively; two-mediator path of negative emotions via low self-control, negative emotions via NSSI, and low self-control via NSSI, and three-mediator path from negative emotions to NSSI via low self-control.

CONCLUSIONS

This longitudinal study provides evidence that sleep problems in adolescents may increase suicidal behavior by exacerbating negative emotions, weakening self-control, and promoting NSSI. The findings suggest sleep problems should be addressed in suicide prevention and intervention efforts for adolescents.

Management of Psychiatric Emergencies Among Migrant Youth in Institutional and Community Settings

Migrant youth commonly access mental health care for the first time during emergencies, rather than through ambulatory means. Suicidal behaviors may occur more often among migrants than nonmigrant youth, and they may suffer from post-traumatic stress, depression, anxiety, and display disruptive behaviors more frequently than their nonmigrant counterparts. Brief emergency interventions include safety planning, psychoeducation, parent training on communication and establishing routines, and behavioral therapies like activity scheduling and sleep hygiene.

Associations between Sleep Disturbance and Suicidal Ideation Severity in Iranian University Students: Evaluating Emotion Regulation Difficulties and Distress Tolerance

AIM

Although sleep disturbance is associated with suicide ideation, underlying cognitive-affective mechanisms that may explain this association are not well understood. The aim of the present study was to concurrently evaluate whether emotion regulation difficulties and distress tolerance explain this association among Iranian university students.

METHOD

A total of 679 Iranian university students (66.42% females; Mage = 24.34 years, SD = 4.86) completed a battery of online self-report questionnaire. Structural equation modeling was used to empirically explore the relations among variables.

RESULTS

Sleep disturbance was positively associated with suicide ideation. Higher sleep disturbance symptoms were associated with higher levels of suicide ideation. Sleep disturbance was indirectly related to suicide ideation through both emotion regulation difficulties and distress tolerance.

CONCLUSION

Findings expand knowledge of cognitive-emotional processes that may explain the sleep disturbance-suicide ideation association among Iranian university students. Iranian students experiencing sleep disturbance may benefit from intervention strategies targeting emotion regulation skills and distress tolerance to reduce suicide ideation.

Sleep disturbance and suicidal ideation mediated by psychotic-like experiences in adolescents: a two-wave longitudinal study

STUDY OBJECTIVES

Sleep disturbance may cause suicidal ideation (SI). This study aimed to examine their co-occurrence rate among adolescents and investigate whether psychotic-like experiences (PLEs) mediate this association.

METHODS

A total of 17 722 Chinese adolescents were included in this two-wave longitudinal study. The baseline survey (time 1, T1) was conducted between April 21 and May 12, 2021, and the follow-up survey (time 2, T2) was implemented between December 17 and 26, 2021. At T1, participants completed questionnaires to assess their sleep disturbance, sleep duration, PLEs, SI, depressive symptoms, and sociodemographic characteristics. At T2, participants reported their PLEs, SI, and negative life events.

RESULTS

The SI prevalence decreased from 20.2% (T1) to 18.4% (T2). Participants with SI showed significantly higher prevalence of sleep disturbance and short sleep duration compared to those without SI. Baseline sleep disturbance and short sleep duration were both associated with the increased risk of SI 6 months later. These longitudinal links were mediated by PLEs, independent of baseline covariates and negative life events.

CONCLUSIONS

These findings provide a novel insight into the mechanism linking sleep problems and suicidality, and stress the significance of assessing and addressing sleep problems and PLEs for adolescent suicide prevention and intervention.

Classification and Epidemiology of Sleep Disorders in Children and Adolescents

Sleep disturbances are common in children and adolescents but still remain unrecognized and undertreated. Several classification systems of sleep disorders are available, which include recent attempts to develop more specific nosologic categories that reflect developmental aspects of sleep. The prevalence of sleep disorders has been studied across various samples of healthy, typically developing children and those with special medical, psychiatric, and neurodevelopmental needs. Sleep disorders are highly prevalent in children and adolescents with psychiatric disorders, making it important for mental health professionals to be aware of sleep problems and to address them in the context of psychiatric comorbidities.

Associations between insomnia symptom trajectories with depression and self-harm behaviors in Chinese college students before and during the COVID-19 pandemic: A five-wave longitudinal investigation

BACKGROUND

Sleep problems are highly prevalent during COVID-19 pandemic. However, only very limited studies have examined the changing patterns of insomnia symptom before and during the COVID-19 pandemic, and most of these studies were limited to two-wave designs and the variable-centered approach.

METHODS

The data was taken from a large-scale health-related cohort among Chinese college students. This cohort was a five-wave design and 3834 participants who completed at least two waves were included in the present study. Growth mixture modeling (GMM) was used to estimate trajectory classes for insomnia symptoms, followed by binary logistic regression to explore the association between trajectory classes and subsequent mental health problems.

RESULTS

GMM analyses extracted four distinct trajectories of insomnia symptoms: stable-low pattern (n = 2897, 75.6 %), increasing pattern (n = 405, 10.6 %), decreasing pattern (n = 182, 4.7 %), and stable-high pattern (n = 350, 9.1 %). Additionally, we found that individuals in stable-high and increasing patterns were more likely to experience mental health problems after the COVID-19 pandemic even after adjusting significant covariates and outcomes at baseline.

CONCLUSIONS

Appreciable heterogeneity in insomnia symptoms among college students was revealed before and during the COVID-19 pandemic. About 20 % of college students were classified as high-risk patterns of insomnia symptoms. Psychological interventions should target such vulnerable groups to reduce the rates of mental health problems.

Associations between sleep complaints, suicidal ideation and depressive symptoms among adolescents and young adults in Greece

Depression prevalence increases significantly during adolescence/early adulthood. Depression in youth may present suicidal ideation, while suicide represents the leading cause of death in this age group. Moreover, adolescents/young adults frequently report sleep complaints that may partially be due to depressive symptoms. Studies on the associations between depression, sleep complaints and suicidality in this age group are limited. We aimed to examine associations between depressive symptoms, sleep complaints and suicidal ideation in a large (n = 2771), representative sample of adolescents (age: 15-17 years, n = 512) and young adults (age: 18-24 years, n = 2259) from the general population in Greece. A telephone structured questionnaire was administered. Depressive symptoms were assessed using the modified Patient Health-7 questionnaire score, while presence of suicidal ideation and sleep complaints were assessed using the ninth and third question of Patient Health-9 questionnaire, respectively. Mediation logistic regression analysis revealed significant direct paths from depressive symptoms to sleep complaints (odds ratio [OR] 1.22, 95% confidence interval [CI] 1.19-1.24; OR 1.21, 95% CI 1.18-1.24) and suicidal ideation (OR 1.18, 95% CI 1.14-1.22; OR 1.18, 95% CI 1.14-1.22), as well as sleep complaints and suicidal ideation (OR 1.82, 95% CI 1.32-2.50; OR 1.91, 95% CI 1.33-2.76) in the total group and in young adults, respectively, but not among adolescents. Moreover, we detected a significant indirect effect of depressive symptoms on suicidal ideation mediated by sleep complaints (18.8%) in young adults. These findings support the hypothesis that treatment of sleep disturbances among youth with depression may independently further reduce suicidal risk.

Sleep disorders and relative risk of suicidal ideation and suicide attempts in youth presenting to emergency departments

OBJECTIVE

Sleep problems predict suicide, which is a leading cause of death in adolescents and young adults, but the relative risk of suicidality in youth with sleep disorders has not been established in nationally representative samples. This study evaluated the relative risk of suicidal ideation and attempt in youth ages 6-24 who presented to United States emergency departments between 2015 and 2017.

METHODS

Youths' diagnoses of sleep and psychiatric disorders, and emergency department encounters with suicide attempt and suicidal ideation, were extracted from the Health Care Cost Utilization Project's Nationwide Emergency Department Sample (N = 65,230,478). Relative risk of suicidal ideation and suicide attempt were evaluated through logistic regression and predicted rate ratios after adjustment for history of self-harm and demographic characteristics.

RESULTS

Youth with at least 1 sleep disorder had 3 times greater odds of an emergency department encounter involving suicidal ideation compared to those without a sleep disorder (aOR = 3.22, 95% CI: 2.61, 3.98). The predicted probability of suicidal ideation was 46.03% higher in youth with a mood disorder and a sleep disorder, and 47.04% higher in youth with a psychotic disorder and sleep disorder, compared to youth without a sleep disorder. Only 0.32% of youth presenting to emergency departments were diagnosed with a sleep disorder.

CONCLUSIONS

Sleep disorders are associated with increased risk for suicidal ideation in youth presenting to emergency departments. Sleep disorders are also underdiagnosed in youth presenting to emergency departments relative to their estimated prevalence in epidemiologic surveys. Research and public health campaigns to prevent suicide in youth should incorporate assessment and intervention for sleep disorders.

Health Diagnoses and Service Utilization in the Year Before Youth and Young Adult Suicide

OBJECTIVE

Suicide rates among young people are rising. Health care visits provide opportunities for identification and intervention, yet studies have been limited by small or circumscribed samples. This study sought to expand the knowledge base by examining health care encounters and diagnoses among young people who later died by suicide.

METHODS

This case-control study examined diagnoses of mental and general medical disorders and health care utilization in the 30 and 365 days before suicide death in nine large U.S. health care systems. Data (years 2000-2015) from 445 suicide decedents ages 10-24 years were matched with data from 4,450 control group patients.

RESULTS

Suicide decedents were more likely to have at least one mental disorder diagnosis (51% vs. 16%; adjusted OR [AOR]=5.74, 95% CI=4.60-7.18) and had higher rates of nearly all mental health conditions. Substance use disorders were common (12%) and more likely (AOR=8.50, 95% CI=5.53-13.06) among suicide decedents. More than one in three (42%) suicide decedents had a health care visit in the month before death, and nearly all (88%) had a visit in the previous year.

CONCLUSIONS

Despite the greater likelihood of suicide associated with mental disorder diagnoses, such disorders were present among only 51% of suicide decedents. High rates of health care utilization among suicide decedents indicate a need for improving identification of mental health conditions and suicide risk across the health care system. Increased substance use screening may help identify youths at high risk because substance use disorders were significantly more prevalent and likely among suicide decedents.

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.

[Psychometric Evaluation of a Single-Item-Screener for Sleep Disturbances]

OBJECTIVE

Sleep disturbances are one of the most prevalent health complaints in the general population. Thus, the need for validated screening instruments and prevention measures is high. The aim of the current study is to evaluate a potential single-item screening instrument and therefore, contribute to an improved early detection.

METHODS

Data from Saxony Longitudinal Study (SLS) is being analyzed. Based on data of 32nd wave (n=321, 172 women, 149 men, M age=48.42, SD=0.64), the G-Score Item #3 ("Have you had the following complaints in the last 12 months? Please indicate how often they occurred. - sleeplessness"), a potential screening instrument, is psychometrically evaluated. A Receiver Operating Characteristic (ROC)-Analysis is calculated to assess the predictive validity of the G-Score Item #3.

RESULTS

Retestreliability for the G-Score Item #3 is 0.70 (p<0.001). Correlation with the Jenkins Sleep Scale (JSS) was r=0.79 (p<0.01). The area under the curve (AUC) is 0.92, providing evidence for a very good predictive validity.

DISCUSSION AND CONCLUSION

This study provides evidence for the use of the G-Score Item #3 as a screening instrument for sleep disturbances by showing good psychometric properties and brevity.

Sleep and substance use: Practice considerations for social workers

Poor sleep health is consistently associated with the initiation of substance use, development of substance use disorders (SUDs), dropout from treatment, and return to use. Quality sleep health holds promise as a modifiable factor that can reduce the occurrence and severity of SUDs. Unfortunately, social workers typically receive little to no training in the assessment and evidence-based treatment of sleep disorders. This article, authored by an interdisciplinary team of clinicians and researchers, provides important sleep and SUD considerations for social workers. After providing a summary of the empirical literature surrounding the relationship between sleep and SUDs, we discuss the inclusion of the following in SUD treatment settings: (1) sleep health assessments, (2) psychoeducation on behaviors to promote healthy sleep, (3) referral to appropriate specialists when sleep disorders are suspected, (4) the promotion of a healthy sleep environment in residential treatment settings, and (5) evidenced-based behavioral interventions.

Early childhood sleep problems predict increased risk for the later development of suicidal thoughts

Suicidal thoughts and behaviors in youth are an escalating and immediate public health concern. To better understand youth suicidal thoughts and behaviors, it is important to identify risk factors in early childhood that predict the later emergence of youth suicidal thoughts and behaviors. Research with adults and adolescents has identified sleep disturbances as a risk factor for suicidal thoughts and behaviors, but this has yet to be examined in early childhood. Using a prospective, 17-year longitudinal design, the current study explored the association between early childhood sleep disturbances and concurrent and later suicidal thoughts and behaviors (in separate models) across childhood and adolescence. Results indicate that sleep problems in early childhood are associated with increased probability for suicidal thoughts after age 8, even when controlling for prior and concurrent depression severity. Our findings suggest that early childhood sleep difficulties warrant increased clinical attention and management, as they may contribute to the maintenance and exacerbation of suicidal thoughts over time.

Worry-related sleep problems and suicidal thoughts and behaviors among adolescents in 88 low-, middle-, and high-income countries: an examination of individual- and country-level factors

A strong association between sleep problems and suicidal thoughts and behaviors (STBs) has been demonstrated in high-income countries. The sleep-STB relationship, however, is minimally understood among youth in low and middle-incomes countries. There also is a limited understanding of how individual- (i.e., age, sex) and country-level (i.e., economic inequality, economic quality) factors may moderate the magnitude of the sleep-STB association among youth. Data were analyzed from the cross-national Global School-based Health Survey 2003-2017, which assessed a range of health behaviors among school-enrolled adolescents aged 11-18 years from 88 low-, lower-middle, upper-middle, and high-income countries. Multilevel models were used to examine the influence of individual- and country-level factors on the association between past-year worry-related sleep problems and past-year suicide ideation, suicide plans, and suicide attempts. Worry-related sleep problems were significantly associated with suicide ideation, plans, and attempts. Adolescent sex, country economic quality (income group designation), and country economic inequality moderated the sleep-STB association, but age did not. The sleep-STB relationship was stronger for males and across macroeconomic indices, the relationship was generally strongest among upper-middle income countries (economic quality) and countries with a big income gap (economic inequality). When examining how individual-level factors differentially affected the sleep-STB relationship within economic quality (income group designation), the effects were driven by older adolescents in high-income countries for suicide ideation and suicide plans. Study findings suggest an important role for global macroeconomic factors, for males, and older adolescents in high-income countries in the sleep-STB relationship. Future directions include expanding worldwide coverage of countries, assessing a wider range of sleep problems, and longitudinal work to understand potential mechanisms in the sleep-STB relationship.

Adolescent sleep quality and quantity and educational attainment: a test of multiple mechanisms using sibling difference models

OBJECTIVE

The objective of this study is to determine whether and how sleep quality and quantity during adolescence are related to educational attainment in adulthood. This study also investigates whether this relationship varies by gender.

METHODS

Using data from the National Longitudinal Study of Adolescent to Adult Health, the present study employed a sibling fixed effect approach that takes into account unobserved family background factors such as genetics and social environments. Gender-stratified analyses were conducted to consider the potential gendered relationship between adolescent sleep and educational attainment.

RESULTS

Controlling for unobserved family-level heterogeneity attenuated the associations between adolescent sleep characteristics and educational attainment, albeit in different ways for boys and girls. Gender-stratified models suggest that, for boys, only the association between short sleep duration and educational attainment was robust to adjustment for sibling fixed effects. In contrast, for girls, among three sleep quality measures, only trouble falling or staying asleep remained significantly associated with educational attainment even after controlling for unobserved family heterogeneity. Sibling fixed effects estimates suggest that short sleep duration (6 or fewer hours per night) was negatively associated with years of schooling only among boys (b = -0.443), whereas trouble falling or staying asleep was associated with a reduction in years of schooling only among girls (b = -0.556). The mechanisms underlying the observed associations also differed by gender. For boys, the association between short sleep duration and educational attainment was partially explained by a combination of educational, social, and psychological factors. Only intermediate educational factors explained part of the association between trouble falling or staying asleep and educational attachment among girls.

CONCLUSIONS

The study's finding that the relationship between adolescent sleep characteristics and educational attainment and the mechanisms underlying this relationship differ by gender calls attention to the need for gender-specific interventions.

Healthy sleep for healthy schools: A pilot study of a sleep education resource to improve adolescent sleep

ISSUE ADDRESSED

Insufficient sleep and unhealthy sleep practices in adolescents are associated with significant health risks. Sleep education programs in schools aim to improve sleep behaviour. A new eLearning sleep education program, Healthy Sleep for Healthy Schools (HS4HS), was developed focused on these goals and is distinguishable from other sleep education programs because it is delivered by teachers, making it more sustainable and adaptable for schools. We aimed to evaluate if HS4HS would improve student sleep knowledge, healthy sleep practices, sleep duration and reduce sleepiness. We also aimed to understand if this intervention could be successfully implemented by trained teachers.

METHODS

Teachers trained in sleep delivered HS4HS to 64 South Australian students in year 9 (aged 13-14 years) over 6 weeks during regular school curriculum. A sleep education survey assessing sleep patterns (such as healthy sleep practices, time in bed and sleepiness), and a sleep knowledge questionnaire was completed pre- and post-HS4HS delivery. Evaluations were also completed by teachers.

RESULTS

Sleep knowledge and healthy sleep practices significantly improved post intervention. Time in bed on both school days and weekends increased slightly and sleepiness decreased slightly, but these changes were not statistically significant. Teachers found the program useful, comprehensive and easy to incorporate into their curricula.

CONCLUSIONS

After short training, teachers can deliver sleep education during class and improve sleep practices in their students. This suggests that this program may offer potential as an effective and useful resource for teachers wanting to include sleep health in their curriculum. SO WHAT?: Sleep is the foundation of good health and teachers can promote and integrate sleep education into their curricula for the first time with this online teacher focussed program, which has the potential to be a sustainable sleep health promotion resource.

The association between sleep and suicidality in the presence and absence of depressive symptoms: A cross-sectional study in rural China

This study aimed to explore the association between sleep and suicidality in the presence and absence of depressive symptoms in the rural Chinese population. The research involved a cross-sectional survey conducted in Liuyang, China, between November 2010 and August 2011. A total of 2052 participants were surveyed (987 males and 1065 females). To investigate the mediating effect of depressive symptoms in the correlation between sleep quality and suicidality. The association between sleep quality and suicidality in the absence of depressive symptoms was also explored. Suicide risk was measured using the Mini-International Neuropsychiatric Interview subscale. The visual analog scale was used to assess sleep quality. Patient Health Questionnaire-9 and Patient Health Questionnaire-2, avoiding the overlap in sleep and suicidality assessments, were used for detecting depressive symptoms in participants. Depressive symptoms partially mediated the association between sleep quality and suicidality among rural adults. Furthermore, some participants did not exhibit depressive symptoms in this study yet still exhibited a risk for suicidality, with poor sleep quality contributing significantly to their suicidality even after adjusting for cofounders. Poor sleep quality significantly increases the likelihood of suicidality in the presence and absence of depressive symptoms in the rural Chinese population. Poor sleep quality could correlate with increased suicide risk independently of depressive symptoms.

Persistent suicidal ideation in a large intensive outpatient adolescent population sample: A preliminary report on the role of sleep disturbance

Sleep disturbance is a unique, yet understudied, risk factor for suicidal thoughts and behaviors (STBs). The present study sought to explore the relationship between suicidal ideation (SI) and self-reported sleep disturbance in a sample of adolescents in an intensive outpatient program targeting suicidality (N = 691). Analyses conducted include paired samples t tests, multiple linear regression, and analysis of variance to examine group differences in sleep disturbance over time. Sleep disturbance and SI were associated at each timepoint, and sleep disturbance at admission predicted SI at discharge. Those with the most severe SI at discharge indicated increased sleep disturbance relative to admission, whereas those reporting no SI at discharge nearly resolved all sleep difficulties. Future studies should utilize objective sleep measures, longitudinal assessments, and include a more diverse sample to better inform the relationship of sleep and SI. These findings suggest that directly managing sleep disturbance during treatment could decrease the risk of STBs.

Dynamic Regulatory Processes in the Transition from Suicidal Ideation to Action in Adults Leaving Inpatient Psychiatric Care: An Intensive Longitudinal Study Protocol (Preprint)

Background

US suicide rates have risen steadily in the past decade, and suicide risk is especially high in the months after discharge from inpatient psychiatric treatment. However, suicide research has lagged in examining dynamic within-person processes that contribute to risk over time among individuals known to be at high risk of suicide. Almost no research has examined how affective, cognitive, and physiological processes change over minutes, hours, or days to confer risk of suicidal behavior in daily life.

Objective

This protocol describes a longitudinal study designed to examine real-world changes in risk of suicide across multiple assessment domains. Specifically, the study involves following adults known to be at high risk of suicide after discharge from inpatient psychiatric care using self-report, interview, actigraphy, and behavioral methods to identify proximal contributors to suicidal thoughts and behaviors. First, we hypothesize that negative affective experiences, which are featured in most major suicide theories, will comprise a latent factor indicative of psychache (emotional pain), which will predict increases in suicidal thinking over time. Second, we hypothesize that poor inhibitory control in the context of negative affective stimuli, as well as emotion-related impulsivity, will predict the transition from suicidal thinking to suicidal behavior over time. Third, we hypothesize that short sleep duration will precede within-person increases in suicidal ideation as well as increased odds of suicidal behavior among those reporting suicidal thoughts.

Methods

The desired sample size is 130 adults with past-week suicidal thoughts or behaviors who are receiving inpatient psychiatric treatment. Participants will complete a battery of measures while on the inpatient unit to assess negative affective experiences, emotion-related impulsivity, inhibitory control, typical sleep patterns, and relevant covariates. After discharge from inpatient care, participants will complete 4 weeks of signal-contingent ecological momentary assessment surveys, as well as mobile behavioral measures of inhibitory control, while wearing an actigraphy device that will gather objective data on sleep. Participants will complete interviews regarding suicidal thoughts and behaviors at 4 and 8 weeks after discharge.

Results

The study was funded by the National Institutes of Health in November 2020. Recruitment began in April 2021. Data analysis will begin after completion of data collection.

Conclusions

This study will elucidate how affective, cognitive, and physiological risk factors contribute (or do not contribute) to within-person fluctuations in suicide risk in daily life, with important implications for extant theories of suicide. Of import, the examined risk factors are all modifiable; thus, the results will inform identification of key targets for just-in-time, flexible, personalized, digital interventions that can be used to decrease emotional distress and prevent suicide among those at highest risk.

A Comprehensive Review of the Literature on Sleep Difficulties and Suicidality in Youth to Inform an Integrative Developmental Model and Future Directions

Purpose of Review

Suicide is currently the second leading cause of death among youth. Identification of modifiable near-term risk factors can inform suicide prevention strategies. One promising, readily assessed factor is sleep. We critically review the literature on sleep and suicidal thoughts and behaviors among youth.

Recent Findings

Most studies examining the youth sleep-suicidality relationship are from epidemiological samples in which both sleep problems and suicidality were assessed over variable timeframes using limited items from scales not designed to measure these constructs. Nonetheless, these data overwhelmingly support an association between suicidality and a range of sleep difficulties (e.g., insomnia, short/long sleep, weekend oversleep), above and beyond depressive symptoms. Limited studies include clinical samples or prospective designs. We review potential mechanisms and present a developmentally-informed integrative model.

Summary

Literature supports a clear association between sleep difficulties and youth suicidality. Future directions include prospective longitudinal studies and targeted prevention efforts.

The Moderating Role of Lifestyle on Insomnia in Home Quarantine College Students During the COVID-19 Epidemic

There has been sufficient evidence for the relationship between lifestyle and insomnia in the general population, but for individuals who already suffer from insomnia, it is not clear whether a healthy lifestyle can also pose similar benefits. The present study investigated the roles of different aspects of lifestyle in the development of individual insomnia by tracking insomnia symptoms of college students during the COVID-19 lock-down. Two surveys were conducted on 65,200 college students in the process of home isolation in Guangdong Province of China, at the pandemic outbreak period (T1) and the initial remission period (T2), respectively. Given the objectives of the present study, a total of 1,702 college students with clinical insomnia from T1 were selected as subjects. Insomnia symptoms were assessed using the Youth Self Rating Insomnia Scale (YSIS), while demographic information, epidemic exposure, and lifestyle were all measured by self-developed questionnaire, through network survey. The 1,702 college students (mean age ± standard deviation, 20.06 ± 1.46, range 16-25; 71.9% females) with insomnia symptoms were divided into three trajectory groups: recovery group, remission group, and chronic insomnia group according to their insomnia scores in T2 phase. The results showed that there was no significant difference in demographic backgrounds or epidemic exposure among the three groups, however, there were significant differences in food intake, exercise, and Internet use. The regression results further showed that both the recovery group and the remission group adopted more regular food intake than the chronic group. The recovery group exhibited better daily exercise habits than both the remission group and the chronic group. The duration of Internet use was significantly shorter for the recovery group than for the chronic group. These findings indicate a strong relationship between the lifestyle and the recovery of insomnia for college students isolated at home during the epidemic period. Significance of the different aspects of lifestyle on the recovery of insomnia are discussed.

Sleep problems predict next-day suicidal thinking among adolescents: A multimodal real-time monitoring study following discharge from acute psychiatric care

Suicidal thoughts and behaviors (STBs) are major public health concerns among adolescents, and research is needed to identify how risk is conferred over the short term (hours and days). Sleep problems may be associated with elevated risk for STBs, but less is known about this link in youth over short time periods. The current study utilized a multimodal real-time monitoring approach to examine the association between sleep problems (via daily sleep diary and actigraphy) and next-day suicidal thinking in 48 adolescents with a history of STBs during the month following discharge from acute psychiatric care. Results indicated that specific indices of sleep problems assessed via sleep diary (i.e., greater sleep onset latency, nightmares, ruminative thoughts before sleep) predicted next-day suicidal thinking. These effects were significant even when daily sadness and baseline depression were included in the models. Moreover, several associations between daily-level sleep problems and next-day suicidal thinking were moderated by person-level measures of the construct. In contrast, sleep indices assessed objectively (via actigraphy) were either not related to suicidal thinking or were related in the opposite direction from hypothesized. Together, these findings provide some support for sleep problems as a short-term risk factor for suicidal thinking in high-risk adolescents.

Adolescent Sleep and Mental Health Across Race/Ethnicity: Does Parent-Child Connectedness Matter?

OBJECTIVE

Sleep is vital for healthy development, yet most adolescents do not meet recommended nightly hours. Although racial/ethnic minorities often experience relatively worse sleep outcomes compared with White peers, little is known about how the sleep-mental health relationship holds across diverse groups or how family relationships affect this association.

METHOD

Using data on 8th, 9th, and 11th grade public school respondents to the 2016 Minnesota Student Survey (N = 113,834), we conducted univariate, bivariate, and multivariate analyses to examine whether sleep duration was associated with depressive symptoms, suicide ideation, and suicide attempt, adjusting for sociodemographic covariates. Furthermore, we examined the effect of the parent-child connectedness by sleep interaction on these relationships. Analyses were conducted for 9 racial/ethnic groups collectively and separately.

RESULTS

Overall, youth sleep duration and parent-child connectedness were independently associated with reduced rates of depressive symptoms, suicide ideation, and suicide attempt. There was significant interaction between parent-child connectedness and sleep, demonstrating that connectedness magnifies the benefits of the sleep-mental health relationship. Main effects of sleep and parent-child connectedness for mental health were similar for most individual racial/ethnic groups, although magnitudes varied. The connectedness-sleep interaction only remained significant for White and Asian youth on select suicide-related outcomes.

CONCLUSION

Despite racial/ethnic differences, adolescent sleep and parent-child connectedness both seem to buffer youth from poor mental health in a large, multiethnic sample. On the whole, these factors demonstrate a synergistic protective effect and reflect promising intervention targets. The extent to which their interactive benefit translates across diverse populations requires additional study.

Advances in Research on Adolescent Suicide and a High Priority Agenda for Future Research

Suicide is the second leading cause of death for adolescents in the United States, yet remarkably little is known regarding risk factors for suicidal thoughts and behaviors (STBs), relatively few federal grants and scientific publications focus on STBs, and few evidence-based approaches to prevent or treat STBs are available. This "decade in review" article discusses five domains of recent empirical findings that span biological, environmental, and contextual systems and can guide future research in this high priority area: (1) the role of the central nervous system; (2) physiological risk factors, including the peripheral nervous system; (3) proximal acute stress responses; (4) novel behavioral and psychological risk factors; and (5) broader societal factors impacting diverse populations and several additional nascent areas worthy of further investigation.

College students' sleep difficulty during COVID-19 and correlated stressors: A large-scale cross-sessional survey study

Objective

Sleep difficulty is one of the main concerns during the COVID-19 pandemic. This study examined factors related to vaccination and physical and psychological health conditions, and sleep difficulty in college students in China.

Methods

An online, cross-sectional, anonymous survey was used to investigate college students' perceived sleep difficulty and relevant components (i.e., physical health condition, psychological distress, knowledge of vaccine, and autonomy of vaccine uptake). Hierarchical ordinal logistic regression was conducted to examine the proposed model with the control of participants' demographics (i.e., gender and age).

Results

Valid data of 3,145 students from 43 universities in mainland China was collected in January 2021. The average age of participants was 20.8 years old (S. D. = 2.09). The majority were single (97.4%), and about half were male (49.8%). Results showed that participants had less psychological distress when they had more knowledge about the COVID-19 vaccine and more autonomy to decide whether to receive it. In addition, participants with better physical health experienced less sleep difficulty. In contrast, those with more psychological distress experienced more sleep difficulty.

Conclusions

These findings can inform healthcare providers about the relationship between different factors and difficulty sleeping and aid them in developing interventions addressing sleep difficulties associated with the global pandemic. Health authorities also can improve vaccine uptake and reduce hesitancies in future vaccination campaigns based on the study results showing that greater vaccine knowledge and autonomy reduced psychological distress.

Sleep disturbance predicts suicidal ideation during COVID-19 pandemic: A two-wave longitudinal survey

BACKGROUND

This study aimed to examine the cross-sectional and longitudinal associations between sleep disturbance and suicidal ideation (SI) in a large cohort of adolescents experiencing the Coronavirus disease 2019 (COVID-19) crisis in China.

METHODS

One two-wave longitudinal web-based survey of sleep, SI, and depression was conducted among 67,905 college students (mean age = 20.23 years, SD = 1.63 years; 31.3% male) during the COVID-19 outbreak (Time1, T1: Feb 3rd to 10th, 2020) and initial remission period (Time2, T2: March 24th to April 3rd, 2020).

RESULTS

At T1 and T2, 8.5% and 9.7% of students reported sleep disturbance, 7.6% and 10.0% reported SI, respectively. The prevalence rates of SI at T1 and T2 increased significantly with sleep disturbance and short sleep duration. After adjusting for demographics, pandemic related factors, and depression at T1, sleep disturbance and short sleep duration at T1 were significantly associated with increased risk for SI at T2. Furthermore, sleep disturbance and short sleep duration predicted the new onset and persistence of SI.

CONCLUSION

These findings suggested that sleep disturbance predicts the development and persistence of SI. Early assessment and treatment of sleep disturbance may be an important strategy for prevention and intervention of SI in individuals after exposure to the special public health emergency of COVID-19.

A Transdiagnostic Self-management Web-Based App for Sleep Disturbance in Adolescents and Young Adults: Feasibility and Acceptability Study

Background

Sleep disturbance and its daytime sequelae, which comprise complex, transdiagnostic sleep problems, are pervasive problems in adolescents and young adults (AYAs) and are associated with negative outcomes. Effective interventions must be both evidence based and individually tailored. Some AYAs prefer self-management and digital approaches. Leveraging these preferences is helpful, given the dearth of AYA treatment providers trained in behavioral sleep medicine. We involved AYAs in the co-design of a behavioral, self-management, transdiagnostic sleep app called DOZE (Delivering Online Zzz’s with Empirical Support).

Objective

This study tests the feasibility and acceptability of DOZE in a community AYA sample aged 15-24 years. The secondary objective is to evaluate sleep and related outcomes in this nonclinical sample.

Methods

Participants used DOZE for 4 weeks (2 periods of 2 weeks). They completed sleep diaries, received feedback on their sleep, set goals in identified target areas, and accessed tips to help them achieve their goals. Measures of acceptability and credibility were completed at baseline and end point. Google Analytics was used to understand the patterns of app use to assess feasibility. Participants completed questionnaires assessing fatigue, sleepiness, chronotype, depression, anxiety, and quality of life at baseline and end point.

Results

In total, 83 participants created a DOZE account, and 51 completed the study. During the study, 2659 app sessions took place with an average duration of 3:02 minutes. AYAs tracked most days in period 1 (mean 10.52, SD 4.87) and period 2 (mean 9.81, SD 6.65), with a modal time of 9 AM (within 2 hours of waking). DOZE was appraised as highly acceptable (mode≥4) on the items “easy to use,” “easy to understand,” “time commitment,” and “overall satisfaction” and was rated as credible (mode≥4) at baseline and end point across all items (logic, confident it would work, confident recommending it to a friend, willingness to undergo, and perceived success in treating others). The most common goals set were decreasing schedule variability (34/83, 41% of participants), naps (17/83, 20%), and morning lingering in bed (16/83, 19%). AYAs accessed tips on difficulty winding down (24/83, 29% of participants), being a night owl (17/83, 20%), difficulty getting up (13/83, 16%), and fatigue (13/83, 16%). There were significant improvements in morning lingering in bed (P=.03); total wake time (P=.02); sleep efficiency (P=.002); total sleep time (P=.03); and self-reported insomnia severity (P=.001), anxiety (P=.002), depression (P=.004), and energy (P=.01).

Conclusions

Our results support the feasibility, acceptability, credibility, and preliminary efficacy of DOZE. AYAs are able to set and achieve goals based on tailored feedback on their sleep habits, which is consistent with research suggesting that AYAs prefer autonomy in their health care choices and produce good results when given tools that support their autonomy.

Understanding Somatic Symptoms Associated with South Korean Adolescent Suicidal Ideation, Depression, and Social Anxiety

Korea's suicide rate has increased steadily in recent years and it has become the leading cause of death among Korean youth. This paper aims to propose suicide risk identification strategies for South Korean youth by identifying profiles of suicide risk alongside reported somatic complaints. For several reasons, somatic complaints are more commonly reported than mental health concerns in Korea, where somatic complaints are likely to be representative of larger mental health worries. Nationally representative data of Korean first-year middle school students were used to identify mental health profiles by examining reported suicidal ideation, depression, and social anxiety and the prediction effect of reported somatic symptoms within these profiles. Results indicated that female students reported a greater level of suicidal ideation, depression, and social anxiety compared to male students. Each gender (females and males) exhibited five different mental health profile groups, which ranged from low risk to high risk. Somatic symptoms (sleep, stomach ache, tiredness, breathing, appetite, headache, fever, nausea) significantly predicted each profile group, with sleep issues serving as the strongest predictor for risk across both genders and all groups. Therefore, for mental health professionals working with Korean youth, it is encouraged to identify and recognize somatic complaints as potentially representative of mental health concerns and suicidality risk.

Food Insecurity and Sleep Disturbance Among 223,561 Adolescents: A Multi-Country Analysis of Cross-Sectional Surveys

This study was to investigate the association between food insecurity (FI) and sleep disturbance among adolescents. Based on the cross-sectional data of the Global School-based Student Health Survey, this study analyzed self-reported data from adolescents in 68 countries. Multivariate logistic regression and meta-analysis were used to evaluate the association between FI and sleep disturbance. The final sample included 223,561 adolescents. The prevalence of severe FI and sleep disturbance was 6.4% and 8.0%, respectively. Severe FI was significantly associated with a higher risk of sleep disturbance in 48 of the 68 countries after adjusting for covariates, with a pooled OR (95% CI) of 1.94 (1.79-2.09). Overall, the association between FI and sleep disturbance was similar across countries and gender, though a large level of heterogeneity existed across upper- and middle-income countries. Identifying adolescents suffering from FI and remedying the FI severity may be important to improve sleep quality in global adolescents.

The Many Faces of Sleep Disorders in Post-Traumatic Stress Disorder: An Update on Clinical Features and Treatment

Sleep disorders and nightmares are core symptoms of post-traumatic stress disorder (PTSD). The relationship seems to be bidirectional, and persistent disturbed sleep may influence the course of the disorder. With regard to sleep quality, insomnia and nocturnal anxiety symptoms, as well as nightmares and stressful dreams, are the most prominent sleep symptoms. Polysomnographic measurements reveal alterations of the sleep architecture and fragmentation of rapid eye movement sleep. In addition, sleep disorders, such as sleep-related breathing disorders and parasomnias are frequent comorbid conditions. The complex etiology and symptomatology of trauma-related sleep disorders with frequent psychiatric comorbidity require the application of multimodal treatment concepts, including psychological and pharmacological interventions. However, there is little empirical evidence on the effectiveness of long-term drug treatment for insomnia and nightmares. For nondrug interventions, challenges arise from the current lack of PTSD-treatment concepts integrating sleep- and trauma-focused therapies. Effective therapy for sleep disturbances may consequently also improve well-being during the day and probably even the course of PTSD. Whether early sleep interventions exert a preventive effect on the development of PTSD remains to be clarified in future studies.

Trends in Adolescent Online and Offline Victimization and Suicide Risk Factors

OBJECTIVE

Suicidal ideation and plans are increasing among US adolescents. Changing prevalence of online victimization is frequently hypothesized as an explanation for this increase. We tested trends in online and offline victimization and whether they contribute to recent trends in adolescent suicidal outcomes.

METHODS

Youth Risk Behavior Survey data (2011-2019, N = 73 074) were collected biennially through national cross-sectional surveys of US school-attending adolescents. We examined trends in past-year victimization. We also examined whether the relationship between victimization and past-year suicidal ideation, plans, attempts, and injury changed over time using survey-weighted logistic regressions that adjusted for sex and race and ethnicity. We also sex-stratified results to examine sex differences.

RESULTS

Although suicidal ideation and plans increased among US adolescents (mainly girls), online and offline victimization prevalence did not increase over time (offline: 20.0% in 2011, 19.5% in 2019; online: 16.2% in 2011, 15.7% in 2019). Online and offline victimization were associated with suicidal outcomes, especially co-occurring online and offline victimization (eg, adjusted odds ratio [co-occurring online and offline victimization versus none, outcome: suicidal injury] = 8.37; 95% confidence interval: 7.06-9.91). The magnitude of the associations between victimization and suicidal outcomes largely remained stable over time.

CONCLUSION

Peer victimization prevalence has not sufficiently changed over time in concert with suicidal outcomes to explain increased suicidal outcomes. The prevalence of victimization has remained relatively invariant across time despite growing awareness and programming, making online and offline victimization consistent, socially-patterned risk factors that warrant further monitoring and interventions. Research must examine risk factors beyond victimization to explain increasing suicidal outcomes.

The Longitudinal Association between Sleep Duration and Suicidal Behavior among Chinese Adolescents: The Role of Nonmedical Use of Prescription Drug

OBJECTIVE/BACKGROUND

Abnormal sleep and nonmedical use of prescription drugs are known to be factors associated with suicidal behavior, but the nature of the association between weekday sleep duration and suicidal behavior has not been elucidated. Nonmedical use of prescription drugs may play a mediator role in the association mentioned above.

PARTICIPANTS

There were a total of 3,273 high school students interviewed at baseline with a response rate of 96.8% and followed up at one year (retention rate, 96.1%). The mean (SD) age of the students was 13.7 (1.0) years.

METHODS

Data were drawn from the longitudinal data of the School-based Chinese Adolescents Health Survey. A total of 12 high schools were selected in Guangzhou. Suicidal behavior, weekday sleep duration, and nonmedical use of prescription drugs were measured.

RESULTS

Sleeping < 7 hours/day at time 0 was positively associated with suicidal ideation (Adjusted odds ratio [AOR] = 1.51, 95% CI = 1.21-1.89) and suicide attempts (AOR = 2.35, 95% CI = 1.02-5.38) at time 1. The mediation analyses showed that baseline opioids misuse or sedatives misuse partially mediated the associations of baseline short weekday sleep duration with suicidal ideation and suicide attempts at one-year follow-up.

CONCLUSIONS

Baseline short weekday sleep duration was positively associated with subsequent suicidal ideation and suicide attempts, and nonmedical use of opioids or sedatives partially mediated the associations mentioned above. Suicidal behavior can be prevented, short weekday sleep duration and nonmedical use of prescription drugs may be risk factors for suicidal behavior, and the respective roles of these factors are needed to be better understood.

Sleep problems and complexity of mental health needs in adolescent psychiatric inpatients

Sleep problems are highly co-morbid with psychiatric disorders and are part of the complex and multiple factors contributing to symptoms and functional disability. The current study aimed to determine how sleep problems in the period preceding psychiatric admission relate to profiles of mental health needs in adolescent inpatients. This retrospective study included 424 adolescents (13-17 years) admitted over a five-year period to an acute crisis stabilization unit in a tertiary care pediatric hospital. Adolescents were divided into two age- and sex-matched groups based on the presence of moderate to severe sleep problems. Profiles of mental health needs were assessed at admission using the Child and Adolescent Needs and Strengths - Mental Health Acute (CANS-MH) and a complexity score was calculated as the total number of actionable CANS-MH items. Results showed a positive association between sleep problems and needs pertaining to eating disturbances, adjustment to trauma, and school attendance. Odds ratios for sleep problems increased progressively as the complexity scores increased, reaching a plateau at six needs beyond which odds ratios remained at their highest level. Adolescents with sleep problems were more likely to undergo medication changes during psychiatric hospitalization and were more likely to be discharged with antipsychotic medication. These findings suggest that sleep difficulties in adolescent inpatients may be associated with distinct and more complex profiles of mental health needs. The evaluation of sleep problems early in the course of psychiatric hospitalization may be an important part of the psychiatric assessment process to inform the global treatment plan.

Elevated risk of depression among adolescents presenting with sleep disorders

STUDY OBJECTIVES

Depression is prevalent among patients with sleep disorders, and studies show associations between suicidal ideation and insufficient sleep. Using retrospective clinic records, we examined positive depression screening rates among adolescent sleep clinic patients relative to other subspecialty clinic patients. We also examined relationships between sleep diagnoses and positive depression screening rate in adolescent sleep clinic patients.

METHODS

Data were analyzed from patients ages 12-18 (n = 12,520) who were screened for depression using the Patient Health Questionnaire-2 (PHQ-2). Those who screened positive were administered the PHQ-9. Logistic regression was used to examine effects of age, sex, race, ethnicity, and clinic on likelihood of a positive depression screen. Within sleep clinic patients (n = 308), demographic factors, sleep disorder diagnosis, and body mass index percentile were examined using logistic and linear regression.

RESULTS

Among all patients screened, older age and female sex predicted positive depression screens. Sleep clinic patients were more likely to screen positive than patients in 9 other clinics [odds ratios 2.03-6.83]. Results were similar even when the PHQ-9 sleep item was excluded [odds ratios 2.18-6.41]. Within sleep clinic patients, sleep disorder diagnosis (eg, insomnia, obstructive sleep apnea) was predictive of a positive depression screen (χ²(1) = 10.88, P = .004): insomnia patients were most likely to be experiencing depression.

CONCLUSIONS

Adolescent sleep clinic patients are at increased risk for depressive symptoms. Among insomnia patients, risk was independent of age, sex, and obesity, suggesting a unique relationship between insomnia and affective distress, as has been found in adults. Assessing adolescents for sleep disorders should be prioritized, given the strong association with depression.

Suicidal ideation, psychopathology, and help-seeking in 15 to 19-year-old adolescents in Taiwan: A population-based study 2015-2019

BACKGROUND

Suicide in the young population has been an urgent issue worldwide. The study aimed to assess the overall prevalence of suicide ideation and the associations between adolescent suicide and psychiatric distress/ psychiatric morbidity, as well as the myths and help-seeking behavior of adolescents with suicide ideation.

METHOD

The nationwide community-based telephone interviews were conducted with adolescents aged between 15 to 19 for five consecutive years (2015-2019). The measurements included demographic variables, the five-item Brief Symptom Rating Scale (BSRS-5), and help-seeking experiences of formal medical services or psychological consultations. Stepwise multiple regression analysis was performed to examine which of the five symptoms and demographic variables had discriminative validity for suicidal ideation.

RESULTS

Among 727 participants, the prevalence of lifetime and one-week suicidal ideation was 11.4% and 2.8%, respectively. Adolescents with lifetime/ one-week suicidal ideation and with psychiatric morbidity (BSRS-5≥6) sought psychiatric service more than their counterparts (p<0.001). Female, depression, hostility, and anxiety were significantly associated with suicidal ideation in adolescents.

LIMITATIONS

Telephone interview and structured questionnaire.

CONCLUSION

Adolescents with psychiatric morbidity who have sought help should be carefully monitored for suicidal ideation by parents, teachers, mental health workers, and psychiatric specialists altogether.

Association Between Disturbed Sleep and Depression in Children and Youths: A Systematic Review and Meta-analysis of Cohort Studies

IMPORTANCE

Disturbed sleep represents a potentially modifiable risk factor for depression in children and youths that can be targeted in prevention programs.

OBJECTIVE

To evaluate the association between disturbed sleep and depression in children and youths using meta-analytic methods.

DATA SOURCES

Embase, MEDLINE, PsycINFO, Scopus, Web of Science, and ProQuest Dissertations & Theses Global were searched for articles published from 1980 to August 2019.

STUDY SELECTION

Prospective cohort studies reporting estimates, adjusted for baseline depression, of the association between disturbed sleep and depression in 5- to 24-year-old participants from community and clinical-based samples with any comorbid diagnosis. Case series and reports, systematic reviews, meta-analyses, and treatment, theoretical, and position studies were excluded. A total of 8700 studies met the selection criteria. This study adhered to the guidelines of the Preferred Reporting Items for Systematic Reviews (PRISMA) and Meta-analyses and the Meta-analysis of Observational Studies in Epidemiology (MOOSE) statements.

DATA EXTRACTION AND SYNTHESIS

Study screening and data extraction were conducted by 2 authors at all stages. To pool effect estimates, a fixed-effect model was used if I2 < 50%; otherwise, a random-effects model was used. The I2 statistic was used to assess heterogeneity. The risk of bias was assessed using the Research Triangle Institute Item Bank tool. Metaregression analyses were used to explore the heterogeneity associated with type of ascertainment, type of and assessment tool for disturbed sleep and depression, follow-up duration, disturbed sleep at follow-up, and age at baseline.

MAIN OUTCOME AND MEASURES

Disturbed sleep included sleep disturbances or insomnia. Depression included depressive disorders or dimensional constructs of depression. Covariates included age, sex, and sociodemographic variables.

RESULTS

A total of 22 studies (including 28 895 patients) were included in the study, of which 16 (including 27 073 patients) were included in the meta-analysis. The pooled β coefficient of the association between disturbed sleep and depression was 0.11 (95% CI, 0.06-0.15; P < .001; n = 14 067; I2 = 50.8%), and the pooled odds ratio of depression in those with vs without disturbed sleep was 1.50 (95% CI, 1.13-2.00; P = .005; n = 13 006; I2 = 87.7%). Metaregression and sensitivity analyses showed no evidence that pooled estimates differed across any covariate. Substantial publication bias was found.

CONCLUSIONS AND RELEVANCE

This meta-analysis found a small but statistically significant effect size indicating an association between sleep disruption and depressive symptoms in children and youths. The high prevalence of disturbed sleep implies a large cohort of vulnerable children and youths who could develop depression. Disrupted sleep should be included in multifaceted prevention programs starting in childhood.

Sleep problems in children and adolescents following traumatic life events

Rates of childhood trauma exposure are extremely high, with approximately 70% of children and adolescents experiencing at least one traumatic event. Among the most common non-specific consequences of stress and trauma are disruptions of sleep. Sleep problems, such as shorter sleep duration, difficulty falling asleep, frequent awakenings, nightmares, sleepless nights, and early-morning wakefulness appear to have a higher prevalence among children and adolescents following traumatic events. This review will illustrate the role of sleep problems in traumatized children and adolescents, and emphasize the need to consider a wide range of etiological mechanisms for these symptoms. However, the relationship of trauma exposure to sleep problems among children and adolescents needs further investigation in future research. Moreover, in view of the adverse consequences of long-term disrupted sleep on mental health outcomes following trauma, the need to effectively address sleep disturbances in traumatized children and adolescents is crucial.

The prospective associations between different types of sleep disturbance and suicidal behavior in a large sample of chinese college students

BACKGROUND

Sleep disturbance can be an important predictor associated with suicide behaviors. However, to date, few studies have examined the prospective relationships between different types of sleep disturbance and suicidal behaviors. The current study examined which sleep disturbance types were independent risk factors for subsequent suicidal behaviors in a large sample of Chinese college students.

METHODS

Data came from a large-scale health-related cohort study in Guangdong, China. Participants were 11,740 college students initially assessed in March and April in 2019 and reassessed six month later. Self-administered structured questionnaires were used to assess suicidal behaviors, insomnia, nightmares, sleep disordered breathing (SDB) symptoms, restless legs syndrome (RLS) symptoms, depression, substance abuse and demographic characteristics. A series of logistic regression analyses were conducted to examine the associations between different types of sleep disturbance and suicidal behaviors.

RESULTS

Overall, 12.2% and 1.2% of college students reported suicidal ideation and attempts at baseline, and 8.6% and 2.4% reported similar behavior at follow-up. After adjustment for key covariates and prior suicidal behaviors, frequent nightmares (AORs = 1.35-1.69) and RLS symptoms (AOR = 1.37) at baseline predicted subsequent suicidal ideation, and only frequent nightmares (AOR = 2.40) at baseline predicted subsequent suicidal attempts.

LIMITATIONS

All measures were based on self-report instead of objective assessments or clinical diagnostic evaluations.

CONCLUSIONS

Frequent nightmares and RLS symptoms were independently associated subsequent suicidal ideation or attempts. Screening and managing sleep disturbance may be helpful for reducing the risk of suicidal behaviors among college students.

Classification and Epidemiology of Sleep Disorders in Children and Adolescents

Sleep disturbances are common in children and adolescents but still remain unrecognized and undertreated. Several classification systems of sleep disorders are available, which include recent attempts to develop more specific nosologic categories that reflect developmental aspects of sleep. The prevalence of sleep disorders has been studied across various samples of healthy, typically developing children and those with special medical, psychiatric, and neurodevelopmental needs. Sleep disorders are highly prevalent in children and adolescents with psychiatric disorders, making it important for mental health professionals to be aware of sleep problems and to address them in the context of psychiatric comorbidities.

Association of Outdoor Artificial Light at Night With Mental Disorders and Sleep Patterns Among US Adolescents

IMPORTANCE

Indoor nighttime light exposure influences sleep and circadian rhythms and is known to affect mood-associated brain circuits in animals. However, little is known about the association between levels of nighttime outdoor light and sleep and mental health in the population, especially among adolescents.

OBJECTIVE

To estimate associations of outdoor artificial light at night (ALAN) with sleep patterns and past-year mental disorder among US adolescents.

DESIGN, SETTING, AND PARTICIPANTS

This population-based, cross-sectional study of US adolescents used the National Comorbidity Survey-Adolescent Supplement, a nationally representative cross-sectional survey conducted from February 2001 through January 2004. A probability sample of adolescents aged 13 to 18 years was included. Analyses were conducted between February 2019 and April 2020.

EXPOSURES

Levels of outdoor ALAN, measured by satellite, with means calculated within census block groups. ALAN values were transformed into units of radiance (nW/cm2/sr).

MAIN OUTCOMES AND MEASURES

Self-reported habitual sleep patterns (weeknight bedtime, weeknight sleep duration, weekend bedtime delay, and weekend oversleep) and past-year mood, anxiety, behavior, and substance use disorders, measured via an in-person structured diagnostic interview. Parent-reported information was included in behavior disorder diagnoses.

RESULTS

Among 10 123 adolescents (4953 boys [51.3%]; mean [SE] age, 15.2 [0.06] years [weighted]; 6483 for behavior disorder outcomes), ALAN was positively associated with indicators of social disadvantage, such as racial/ethnic minority status (median [IQR] ALAN: white adolescents, 12.96 [30.51] nW/cm2/sr; Hispanic adolescents: 38.54 [47.84] nW/cm2/sr; non-Hispanic black adolescents: 37.39 [51.88] nW/cm2/sr; adolescents of other races/ethnicities: 30.94 [49.93] nW/cm2/sr; P < .001) and lower family income (median [IQR] ALAN by family income-to-poverty ratio ≤1.5: 26.76 [52.48] nW/cm2/sr; >6: 21.46 [34.38] nW/cm2/sr; P = .005). After adjustment for several sociodemographic characteristics, as well as area-level population density and socioeconomic status, this study found that higher ALAN levels were associated with later weeknight bedtime, and those in the lowest quartile of ALAN reported the longest weeknight sleep duration. Those in the highest quartile of ALAN went to bed 29 (95% CI, 15-43) minutes later and reported 11 (95% CI, 19-2) fewer minutes of sleep than those in the lowest quartile. ALAN was also positively associated with prevalence of past-year mood and anxiety disorder: each median absolute deviation increase in ALAN was associated with 1.07 (95% CI, 1.00-1.14) times the odds of mood disorder and 1.10 (95% CI, 1.05-1.16) times the odds of anxiety disorder. Further analyses revealed associations with bipolar disorder (odds ratio [OR], 1.19 [95% CI, 1.05-1.35]), specific phobias (OR, 1.18 [95% CI, 1.11-1.26]), and major depressive disorder or dysthymia (OR, 1.07 [95% CI, 1.00-1.15]). Among adolescent girls, differences in weeknight bedtime by ALAN (third and fourth quartiles vs first quartile) were greater with increasing years since menarche (F3, 8.15; P < .001).

CONCLUSIONS AND RELEVANCE

In this study, area-level outdoor ALAN was associated with less favorable sleep patterns and mood and anxiety disorder in adolescents. Future studies should elucidate whether interventions to reduce exposure to ALAN may positively affect mental and sleep health.

Associations between sleep quality and psychological distress in early adolescence

Background: Although numerous studies have reported an association between sleep quality and mental health, few have focused on this association exclusively in early adolescence. Targeting this age group is vital as many mental illnesses first emerge during adolescence and remain a significant burden throughout life. Method: In the current study n = 60 participants aged 12 years completed the Pittsburgh Sleep Quality Index (PSQI) and Kessler Psychological Distress Scale (K10). Results: Consistent with previous findings, bivariate correlations revealed significant positive linear relationships between K10 total score and (i) PSQI total score; (ii) sleep quality; (iii) daytime dysfunction; and (iv) sleep disturbance. However, contrary to previous findings, there was no significant correlation between K10 scores and sleep duration. Conclusion: The association between sleep quality and psychological distress in early adolescents provides some important clues about the role that sleep may play in predicting the onset of anxiety and depressive disorders. Longitudinal studies should be undertaken to investigate age-related changes in sleep and psychological distress.

Psychometric Properties of the Persian Pittsburgh Sleep Quality Index for Adolescents

Background: Both cross-sectional and longitudinal studies show that poor sleep is a health concern related to further psychological and physiological issues during adolescence. To assess subjective sleep quality and sleep patterns among adults, the Pittsburgh Sleep Quality Index (PSQI) is a well and internationally established tool. Here, we established the psychometric properties of the Persian version of the PSQI for adolescents. Method: A total of 1477 adolescents (mean age: 15.47 years; 53.2% females) took part in the study. They completed a booklet on sociodemographic information, the Persian version of the PSQI for adolescents, and the Adolescent Sleep Hygiene Scale (ASHS). We relied on classical test reliability approaches of exploratory and confirmatory factor analyses. Results: Classical exploratory factor analysis yielded the seven-factor solution, with concurrent confirmation and overlap with the dimensions of the ASHS, although correlation coefficients were small to medium. A further factor analysis yielded a four-factor solution, explaining 72% of the variance of the PSQI. Further, three out of these four factors predicted the ASHS overall score. Conclusions: The Persian version of the PSQI for adolescents showed satisfactory psychometric properties. It follows that the Persian PSQI is a suitable tool to assess sleep quality and sleep patterns among adolescents.

Later School Start Time: The Impact of Sleep on Academic Performance and Health in the Adolescent Population

The crucial role of sleep in physical and mental health is well known, especially during the developmental period. In recent years, there has been a growing interest in examining the relationship between sleep patterns and school performance in adolescents. At this stage of life, several environmental and biological factors may affect both circadian and homeostatic regulation of sleep. A large part of this population does not experience adequate sleep, leading to chronic sleep restriction and/or disrupted sleep–wake cycles. Studies investigating the effects of different sleep–wake schedules on academic achievement showed that impaired sleep quality and quantity are associated with decreased learning ability and compromised daytime functioning. This review focuses on the most recent studies that evaluated the effects of modified school start time on sleep patterns and related outcomes. Moreover, based on the available empirical evidence, we intend to propose a direction for future studies targeted to implement prevention or treatment programs by modifying sleep timing.

Medications for sleep disturbance in children and adolescents with depression: a survey of Canadian child and adolescent psychiatrists

BACKGROUND

Primary care physicians and child and adolescent psychiatrists often treat sleep disturbances in children and adolescents with mood disorders using medications off-label, in the absence of clear evidence for efficacy, tolerability and short or long-term safety. This study is the first to report Canadian data about prescribing preferences and perceived effectiveness reported by child and adolescent psychiatrists regarding medications used to manage sleep disturbances in children and adolescents with depression.

METHODS

Canadian child and adolescent psychiatrists were surveyed on their perception of effectiveness of a range of medications commonly prescribed for sleep disturbances, their ranked preferences for these medications, reasons for avoiding certain medications, and perceived side effects.

RESULTS

Sixty-seven active child and adolescent psychiatrists completed the survey. Respondents reported noting significant sleep issues in 40% of all their patients. Melatonin and trazodone were identified as the first treatment of choice by 83% and 10% of respondents respectively, and trazodone was identified as the second treatment of choice by 56% of respondents for treating sleep disturbances in children and adolescents with depression. Melatonin (97%), trazodone (81%), and quetiapine (73%) were rated by a majority of respondents as effective. Doxepin, zaleplon, tricyclic antidepressants, zolpidem, or lorazepam were rarely prescribed due to lack of evidence and/or concerns about adverse effects, long-term safety, suitability for youth, suicidality, and dependence/tolerance.

CONCLUSIONS

Melatonin and certain off-label psychotropic drugs are perceived as being more effective and appropriate to address sleep disturbances in children and adolescents with depression. More empirical evidence on the efficacy, tolerability and indications for using these medications and newer group of sleep medications in this population is needed.

Difficulties in Getting to Sleep and their Association with Emotional and Behavioural Problems in Adolescents: Does the Sleeping Duration Influence this Association?

Sleep problems are common in adolescence with a negative impact on the mental health and functioning of adolescents. However, the roles of different sleep problems in relation to emotional and behavioural problems (EBPs), classified according to the 10th version of the International Classification of Diseases as emotional, conduct, hyperactivity and social functioning disorders, are not clear. The first aim of the study was to investigate the association between difficulties in getting to sleep and EBPs in adolescents. The second aim was to explore the role of sleep duration in this association. We used data from the Health Behaviour in School-aged Children (HBSC) study conducted in 2018 in Slovakia. Presented are results for specific age groups of 13-year-old (N = 1909) and 15-year-old (N = 1293) adolescents. Subjective measures of sleep variables were used. Binary logistic regression models adjusted for age and gender were used to assess associations between difficulties in getting to sleep, sleep duration and EBPs measured using the Strengths and Difficulties Questionnaire. Modification of the association between difficulties in getting to sleep and EBPs by sleep duration was also explored. We found that difficulties in getting to sleep at least once a week as well as insufficient sleep (less than 8 h) increased the probability of EBPs. Interactions of sleep duration with difficulties in getting to sleep on EBPs were found to be non-significant. The results suggest that caregivers and clinicians should screen and intervene for both sleep quality and quantity problems in adolescents as they might indicate and promote EBPs.

The roles of repetitive negative thinking and perfectionism in explaining the relationship between sleep onset difficulties and depressed mood in adolescents

OBJECTIVE

The present study investigated the relationship between difficulty initiating sleep and depressed mood and whether it is mediated by repetitive negative thinking. A moderating role of perfectionism was also examined.

METHODS

We surveyed 393 adolescents aged 14 to 20 years (M = 17.32, SD = 1.90) via an online questionnaire that assessed difficulty initiating sleep, repetitive negative thinking, perfectionism, and depressed mood.

RESULTS

Results indicated that repetitive negative thinking fully mediated the relationship between difficulty initiating sleep and depressed mood. In addition, this relationship was moderated by perfectionism, specifically, the relationship between repetitive negative thinking and depressed mood was stronger among more perfectionistic adolescents.

CONCLUSIONS

These findings highlight that repetitive negative thinking is significantly associated with both difficulty initiating sleep and depressed mood, supporting the conceptualization of repetitive negative thinking as a transdiagnostic process. Further, individual differences in perfectionism may amplify the relationship between repetitive negative thinking and mood. The role of repetitive negative thinking and perfectionism in explaining the link between sleep onset problems and depressed mood has important clinical implications through providing possible treatment targets.

Sleep problems and suicide risk in youth: A systematic review, developmental framework, and implications for hospital treatment

OBJECTIVE

Sleep problems are transdiagnostic symptoms that confer significant risk for suicidal thoughts and behaviors (STBs) in adults. However, less is known about the sleep-STB association in adolescence-a developmental period when rates of STBs increase drastically, and sleep problems may be particularly pernicious. This article provides a systematic review of research on the sleep-STB association in youth, an overview of changes in sleep regulation during adolescence that may make sleep problems particularly detrimental for youth, and a discussion of the clinical implications of the sleep-STB association for hospitalized youth.

METHOD

The systematic review included all longitudinal studies in which sleep problems were examined as prospective predictors of STBs in adolescents (aged 10-24 years). The search was conducted on December 1, 2017 using PsychINFO, PubMed, and Web of Science databases.

RESULTS

Ten studies qualified for inclusion in this review. Of these, seven studies found at least one type of sleep problem significantly predicted a STB outcome.

CONCLUSIONS

Although findings are mixed, growing research suggests that sleep problems may be a unique risk factor for STBs in youth. Sleep problems may be particularly important intervention target because they are easily assessed across healthcare settings and are amenable to treatment.
