Delage JP, Côté J, Journault WG, Lemyre A, Bastien CH. The relationships between insomnia, nightmares, and dreams: A systematic review. Sleep Med Rev 2024; 75:101931. [PMID: 38733767 DOI: 10.1016/j.smrv.2024.101931] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2023] [Revised: 03/29/2024] [Accepted: 04/04/2024] [Indexed: 05/13/2024]
Abstract
Insomnia and nightmares are both prevalent and debilitating sleep difficulties. The present systematic review aims to document the relationships between insomnia and nightmares in individuals without a concomitant psychopathology. The relationships between insomnia and dreams are also addressed. PsycINFO and Medline were searched for papers published in English or French from 1970 to March 2023. Sixty-seven articles were included for review. Most results support positive relationships between insomnia variables and nightmare variables in individuals with insomnia, individuals with nightmares, the general population, students, children and older adults, and military personnel and veterans. These positive relationships were also apparent in the context of the COVID-19 pandemic. Some psychological interventions, such as Imagery Rehearsal Therapy, might be effective in alleviating both nightmares and insomnia symptoms. Regarding the relationships between insomnia and dreams, compared with controls, the dreams of individuals with insomnia are characterized by more negative contents and affects. The results show that insomnia and nightmares are connected and may be mutually aggravating. A model is proposed to explain how insomnia might increase the likelihood of experiencing nightmares, and how nightmares can in turn lead to sleep loss and nonrestorative sleep.

Impact of chronotype, insomnia symptoms, sleep duration, and electronic devices on nonrestorative sleep and daytime sleepiness among Japanese adolescents. Sleep Med 2023; 110:36-43. [PMID: 37531897 DOI: 10.1016/j.sleep.2023.07.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Revised: 07/25/2023] [Accepted: 07/26/2023] [Indexed: 08/04/2023]
Abstract
OBJECTIVES Nonrestorative sleep (NRS) and excessive daytime sleepiness (EDS) are important indicators of daytime dysfunction. Electronic media use before bedtime greatly affects adolescent sleep quality. However, few studies have examined factors associated with these symptoms. Therefore, we aimed to investigate the impact of chronotype, electronic device use before bedtime, and insomnia symptoms on NRS and EDS in Japanese adolescents. METHODS A web-based cross-sectional survey of 2067 adolescents was conducted in 2022 to mainly assess sleep-related issues (sleep duration, chronotype, insomnia symptoms, NRS, and EDS), time spent using electronic devices, physical activity, and mental health. RESULTS We analyzed data of 1880 adolescents (age, 16.4 ± 0.8 years; males, 56.7%). NRS and EDS prevalence rates were 54.9% and 39.4%, respectively. In multivariate analysis, evening chronotype [odds ratio (OR): 2.14, 95% confidence interval (CI): 1.58-2.89], difficulty initiating sleep (OR: 1.94, 95% CI: 1.43-2.64), <5 h sleep (OR: 1.77, 95% CI: 1.24-2.54), 5-6 h sleep (OR: 1.52, 95% CI: 1.20-1.93), and using electronic devices just before bedtime (OR: 1.48, 95% CI: 1.08-2.04) were associated with NRS. Evening chronotype (OR: 1.40, 95% CI: 1.07-1.82), early morning awakening (OR: 1.60, 95% CI: 1.02-2.50), using electronic devices just before bedtime (OR: 2.08, 95% CI: 1.48-2.93), and using electronic devices 30 min before bedtime (OR: 1.57, 95% CI: 1.07-2.29) were associated with EDS. CONCLUSION Chronotype may be an important factor influencing NRS and EDS. Discontinuing electronic device use at least 30 min before bedtime could benefit affected adolescents.

Abstract
This study aimed to assess the measurement properties of a simplified Chinese version of the Nonrestorative Sleep Scale (NRSS) among adolescents. We obtained a simplified Chinese NRSS by the standard forward-backward translation procedures and administered it to 486 students who were attending Grade 7-11 in Nanjing, China. Furthermore, Pittsburgh Sleep Quality Index, Athens Insomnia Scale, Centre for Epidemiological Studies Depression Scale, and Toronto Hospital Alertness Test were also self-completed for measuring sleep quality, insomnia, depression and alertness respectively. The sample was randomly split into two halves, with the first half used to explore the scale structure by exploratory factor analysis (EFA), and the second half used to confirm the identified structure by confirmatory factor analysis (CFA). A total of 481 adolescents (49% male) with a mean age of 16 years (range: 13-18) completed this study. In the other half of 250 adolescents, the root mean square error of approximation (RMSEA), standardised root mean square residual, and comparative fit index (CFI) in CFA, which tested the four-factor structure obtained from EFA, were 0.062, 0.051 and 0.975, respectively. Convergent validity was demonstrated from a significant correlation of the simplified Chinese NRSS with sleep quality (r = -0.62), insomnia (r = -0.71), depression (r = -0.60) and alertness (r = 0.54). The internal consistency and test-retest reliability for the global scale were 0.83 and 0.86 respectively. Measurement invariance was established between males and females with the changes of both CFI and RMSEA < 0.01. The simplified Chinese NRSS is valid and reliable for measuring NRS among Chinese adolescents.

Abstract
This study aims to establish a link between disturbances in the night sleep habitus, quality of sleep, and daytime sleepiness in adolescents with Internet addiction and different types of content consumed. Methods: This is a cross-sectional observational study of a school sample in three large cities in Central Siberia. 4615 schoolchildren of 12–18 years old were examined. The Russian-language versions of the Chen Internet Addiction Scale, the Game Addiction Scale for Adolescents, and the Social Media Disorder Scale were used to identify Internet addiction. Questions from the Pittsburgh Sleep Quality Index questionnaire were used to assess nighttime sleep. Daytime sleepiness was assessed using the Pediatric Daytime Sleepiness Scale questionnaire. Results: Adolescents with Internet addiction go to bed and wake up late; they are characterized by a decrease in the duration of nighttime sleep, an increase in sleep onset latency, and frequent nighttime awakenings, as well as more pronounced daytime sleepiness. Among the sleep parameters studied, the indicators of daytime sleepiness and night awakening scales have the highest effect size in Internet-addicted adolescents, regardless of the media consumed. Conclusion: Internet-addicted adolescents are characterized by significant disturbances in the quality of nighttime sleep and excessive daytime sleepiness, which requires appropriate psychological correction.

CHILDREN AND YOUTH SERVICES REVIEW 2021; 126:106012. [PMID: 33846662 PMCID: PMC8028598 DOI: 10.1016/j.childyouth.2021.106012] [Citation(s) in RCA: 22] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Revised: 01/23/2021] [Accepted: 04/06/2021] [Indexed: 02/08/2023]
Abstract
BACKGROUND COVID-19 was first recognized in late 2019 in China, at which time school closures forced most students to isolate at home or maintain social distance, both of which increased smartphone use, daytime sleepiness and post traumatic disorder (PTSD) risks. However, to date, no research has fully explored these behavioral risks or the consequences. METHODS Two thousand and ninety home-confined students from two Chinese high schools participated in an online-based questionnaire battery that assessed their sociodemographic characteristics, COVID-19 related exposures, daytime sleepiness, problematic smartphone use, and PTSD. The subsequent data were subjected to mediation analysis, and structural equation models (SEM) were employed to explore the variable relationships. RESULTS The problematic smartphone use, daytime sleepiness and PTSD prevalence were respectively 16.4%, 20.2% and 6.9%. The number of COVID-19 related exposure was directly associated with problematic smartphone use and PTSD symptoms. Problematic smartphone use was found to be a mediator between COVID-19 related exposure and PTSD symptoms, and daytime sleepiness was found to partially mediate the associations between problematic smartphone use and PTSD. CONCLUSIONS The more exposure associated with the pandemic, the more psychological and behavioral problems the adolescents had. The relatively high rate of problematic smartphone use in home isolated adolescents possibly increased the risk of daytime sleepiness and psychological problems. Therefore, targeted improvements are needed to reduce the risk of psychological problems and daytime sleepiness in adolescents.

Abstract
OBJECT This study examines the validity and reliability of the Sleep Disturbance Scale for Children (SDSC) in the Turkish language. METHOD This scale was translated into the Turkish language by applying the translation-back translation method and content validity analysis. A total of 1903 participants aged 5-15 years were included in the study. A sociodemographic data form, SDSC, and the Children's Sleep Habits Questionnaire (CSHQ) were filled by the parents. Internal consistency analysis, correlation analysis, test-retest analysis, and confirmatory factor analysis were applied to evaluate the reliability and validity of the applied scale. RESULTS The internal consistency of the scale was high (Cronbach α = 0.84). Test-retest reliability was found to be high as well. According to the confirmatory factor analysis, the Turkish version of the scale was compatible with the model of the original scale. According to the T-score evaluation, the frequency of sleep disorders was determined to be 4.15%, and the most common sleep disorder was sleep hyperhidrosis. Correlations between the scores of the SDSC and CSHQ were at a satisfactory level. CONCLUSIONS These results revealed that the SDSC is a valid and reliable scale that can be used in children aged 5-14 years in Turkey to question sleep disorder symptoms.

Abstract
Although engaging in evening naps and extracurricular activities are popular among Japanese high school students, the associations between these behaviors and daytime sleep problems were unclear. A questionnaire on daily life and sleeping habits was administered to 1314 high school students, aged between 15–17 years. The respondents were categorized by their after-school napping habits (did not nap, napped 1–2 days/week, napped ≥3 days/week), and their extracurricular activities (no activity, cultural club, athletic club). The mean nocturnal sleep duration on weekdays (± standard deviation (SD)) was 390 ± 56 min. This was significantly shorter in those students with a higher number of days/week spent napping (p < 0.001), and slightly longer for those in the athletic club (p < 0.001). Sleep problems—including subjective insufficient sleep, excessive sleepiness during class ≥3 days/week, and falling asleep during class ≥3 days/week—were reported by 64%, 55%, and 33% of respondents, respectively. A multiple logistic regression analysis showed significantly higher risks for excessive sleepiness among students taking naps ≥3 days/week, and who belonged to athletic clubs. In addition to those factors, students in cultural clubs revealed significantly higher risks for falling asleep during classes. Future studies are required to decrease daytime sleep problems associated with evening naps and extracurricular activities among high school students.

Abstract
PURPOSE Insomnia symptoms are common in adolescents. This study examined the associations of insomnia symptoms with school performance among adolescents in Shanghai, China. METHODS A total of 4966 adolescents aged 11-20 years participated in a cross-sectional survey during November of 2009. The Adolescent Sleep Disturbance Questionnaire was used to examine insomnia symptoms, and the Teacher School Achievement Form was applied to evaluate adolescents' school performance. RESULTS The results demonstrated that, after adjusting for possible confounders, all 3 dimensions of insomnia symptoms were associated with adolescents' school performance. Difficulty falling asleep problem was associated with poor attention and concentration (odds ratio [OR] = 1.30, 95% confidence interval [CI] 1.11-1.52, P = .001), academic frustration (OR = 1.24, 95% CI: 1.06-1.45, P = .007), and poor school relationships (OR = 1.26, 95% CI: 1.08-1.48, P = .003); maintaining sleep problem was associated with poor attention and concentration (OR = 1.25, 95% CI: 1.06-1.46, P = .007) and poor interest and motivation (OR = 1.22, 95% CI: 1.04-1.44, P = .017); and reinitiating sleep problem was related to poor interest and motivation (OR = 1.20, 95% CI: 1.00-1.45, P = .048). Coexisting insomnia symptoms were associated with poorer school performance, especially in maintaining attention and concentration. CONCLUSIONS The findings of this study highlight the importance of sleep in the social and cognitive development of adolescents.

Abstract
OBJECTIVE Several epidemiological studies have been done on conduct disorder in the Middle East, but no systematic review has been conducted on this topic. Thus, we aimed at investigating the prevalence of conduct disorder in the Middle East in this systematic review of the literature. METHODS We searched all the cross-sectional studies in the scientific databases of PubMed, Scopus, Google Scholar, Index Medicus for the Eastern Mediterranean Region, Islamic World Science Citation Center, and Grey Literature including conference proceedings, and hand searching of key journals from 1995 to the end of 2014. Included studies described the prevalence of conduct disorder prior to age of 18, with any type of random or non-random sampling for at least one gender in the general or school-based populations who resided in Middle Eastern countries. Two reviewers assessed the quality of the included studies independently and extracted the relevant data. RESULTS Twenty-four studies were included in this review. Sample sizes varied from 136 to 9636 with the age range of 6-18 years. These studies were conducted in Iran, Turkey, Israel, Cyprus, Egypt, United Arab Emirates, Iraq, Afghanistan, Yemen, and Palestine. Strengths and Difficulties Questionnaire (SDQ) was used in most of the included studies. The prevalence of conduct disorder was reported from 2.4% by diagnostic criteria taken from DSM-IV-TR in Iraq to 32.9% by SDQ in Iran; the prevalence rates ranged from 1 to 29.9% for females and from 3.3 to 34.6% for males. However, the prevalence of conduct disorder was reported 0.34% by the diagnostic instrument of Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime in Iranian children and adolescents. CONCLUSIONS The prevalence of conduct disorder in this study was higher than the worldwide prevalence, thus, it seems essential to design preventive and treatment programs for children and adolescents with conduct disorder.

To assess sleep behaviors in children with different frequencies of proxy-reported SB. METHODS Parents of 1475 Colombian children, aged 9.8±1.6years, belonging to 3 different social layers, filled out a questionnaire on their childreńs sleep (Childreńs Sleep Habits Questionnaire [CSHQ]). Differences in sleep behaviors were assessed for the total sample and the three socioeconomic layers, using one-way ANOVA and Bonferroni post-hoc tests or Kruskal-Wallis and Dunn's post-hoc tests, based on the normality of outcome variables. RESULTS Most sleep patterns and daytime sleepiness were similar for children with different frequencies of proxy-reported SB, without differences among socioeconomic layers, whilst sleep disorders and parasomnias increased with the frequency of proxy-reported SB, independently on the socioeconomic layer (Bonferroni post-hoc<0.001). The association between sleep-related habits and the frequency of proxy-reported SB was different for each socioeconomic layer. CONCLUSION Among the various sleep behaviors under investigation, some sleep disorders and parasomnias seem to be associated with parental-reported SB in children. The influence of socioeconomic conditions on sleep behaviors seems not relevant. Based on these results, more specific studies on the association between different sleep behaviors are needed. CLINICAL SIGNIFICANCE Sleep behaviors, sociodemographic and socioeconomic features are correlated with SB in adults. However, in children, good evidence about this topic is lacking. This article give information to help clinicians evaluating sleep behaviors, sociodemographic and socioeconomic characteristics, when assessing sleep bruxism, based on evidence.

Abstract
Sleepwalking is thought to be a common arousal disorder; however, the epidemiology of this disorder has not yet been systematically examined. A systematic search of MEDLINE, CINAHL, EMBASE, PsycINFO, PubMed, and ScienceDirect was conducted for 'sleepwalking' OR 'somnambulism' in any field, to identify studies that reported the epidemiology of sleepwalking or sleepwalking disorders. Fifty-one studies assessed the prevalence rates of sleepwalking in a total sample of 100 490. The meta-analysis showed the estimated lifetime prevalence of sleepwalking was 6.9% (95% CI 4.6%-10.3%). The current prevalence rate of sleepwalking-within the last 12 months-was significantly higher in children 5.0% (95% CI 3.8%-6.5%) than adults 1.5% (95% CI 1.0%-2.3%). There was no evidence of developmental trends in sleepwalking across childhood. The significant risk of bias across all studies suggests these results should be used cautiously. Further epidemiological research that addresses methodological problems found in studies of sleepwalking to date is needed.

THE JOURNAL OF SCHOOL HEALTH 2016; 86:298-306. [PMID: 26930242 DOI: 10.1111/josh.12379] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/11/2015] [Revised: 09/13/2015] [Accepted: 07/12/2015] [Indexed: 06/05/2023]
Abstract
BACKGROUND Deficient sleep is linked to detrimental outcomes in health and school performance for adolescents. This study characterized sleep patterns in Chinese adolescents preparing for the College Entrance Exam (CEE) and evaluated the association between sleep patterns, self-rated academic performance, and the CEE scores. METHODS A sample of 481 Chinese adolescents in 12th grade (ages 16-19 years) completed questionnaires about sleep patterns, academic performance, academic stress, and sociodemographic factors 4-6 weeks before the CEE in June 2013. The CEE scores for each student also were obtained. RESULTS A total of 21% of the students had bedtimes after 12:00 am, 78.3% had sleep latency longer than 30 minutes, 14.6% had wake time earlier than 6:00 am, and the vast majority (94.4%) had sleep duration less than 8 hours. After adjusting for selected confounders such as academic stress, prolonged sleep latency was associated with poorer self-reported academic performance, and late bedtime was associated with higher CEE score. CONCLUSIONS Our findings highlight the complex association between sleep and academic performance. Assessing and monitoring sleep patterns in adolescents during periods of high academic demand and stress may yield important recommendations for their health and safety as well as establishing optimal sleep and study habits.
