Objective. The purpose of the study was to examine relationship between self-reported sleep quality and hygiene in Italian American adolescents assess whether sleep-hygiene practices mediate culture quality. Methods. Two nonprobability samples were collected from public schools Rome, Italy, Hattiesburg, Mississippi. Students completed following self-report measures: Adolescent Sleep-Wake Scale, Sleep Hygiene Pubertal Developmental Morningness/Eveningness Scale. Results. final sample included...
Evidence that electroencephalography (EEG) slow-wave activity (SWA) (EEG spectral power in the 1–4.5 Hz band) during non-rapid eye movement sleep (NREM) reflects plastic changes is increasing (Tononi and Cirelli, 2006). Regional assessment of gray matter development from neuroimaging studies reveals a posteroanterior trajectory cortical maturation first three decades life (Shaw et al., 2008). Our aim was to test whether this regional reflected SWA. We evaluated all-night high-density EEG...
Abstract Theoretical models suggest a positive relationship between sleep quality and individuals' ability to regulate emotion. However, few studies have empirically tested this hypothesised link using standardised laboratory measures of emotion-regulation ability. The present research examined the implement type emotion regulation that has particularly important implications for psychological health: cognitive reappraisal (cognitively reframing an emotional event so as dampen its impact)....
The aim of this descriptive analysis was to examine sleep timing, circadian phase, and phase angle entrainment across adolescence in a longitudinal study design. Ninety-four adolescents participated; 38 (21 boys) were 9–10 years ("younger cohort") 56 (30 15–16 ("older at the baseline assessment. Participants completed then follow-up assessments approximately every six months for 2.5 years. At each assessment, participants wore wrist actigraph least one week home measure self-selected timing...
Objective: To examine the associations of child and family sociodemographic characteristics with preschooler bedtime routines. Method: We use parent-report data 3217 3-year-old children (48% black, 26% Hispanic, 22% white) from Fragile Families Child Wellbeing Study to whether are associated presence, time, consistency Results: More than 80% sample have a yet only two thirds follow it. After extensive controls for maternal education, structure, other household characteristics, black Hispanic...
Individual differences in circadian phase preference ("chronotype") are linked to sleep schedule variability, psychosocial functioning, and specific properties of the clock. While much is known about development, distribution, variability chronotype adolescents adults, assessment prepubertal children has been hindered by a lack appropriate, reliable, valid measures. This study presents detailed description children's Children's ChronoType Questionnaire (CCTQ). The CCTQ parent-report, 27-item...
Cognitive and affective processes vary over the course of 24 hour day. Time day dependent changes in human cognition are modulated by an internal circadian timekeeping system with a near-24-hour period. The interacts sleep-wakefulness regulatory to modulate brain arousal, neurocognitive function. Brain arousal is regulated ascending stem, basal forebrain hypothalamic systems inhibition or disruption these reduces impairs cognition, promotes sleep. modulates function projections from master...
Early childhood is a period of dramatic change in sleep and emotion processing, as well time when disturbance both domains are first detected. Although recognized central processing psychopathology, the great majority experimental data have been collected adults. We examined effects acute restriction (nap deprivation) on toddlers' expression. Ten healthy children (seven females; 30-36 months old) followed strict schedule (≥12.5 h bed per 24-h) for 5 days, before each two randomly assigned...
To investigate the associations of caregiver-reported use language-based bedtime routines among preschoolers at age 3 with children's nighttime sleep duration and cognitive, behavioral, health outcomes 5. Furthermore, we wanted to identify whether parental or household characteristics help explain these associations. We used data on 4,274 children from birth 5, drawn Fragile Families Child Wellbeing Study (FFCW), a longitudinal cohort study at-risk born between 1998 2000 in 20 U.S. cities....
Summary This study evaluated the psychometric properties of A dolescent S leep H ygiene cale ( ASHS ), a self‐report measure assessing sleep practices theoretically important for optimal sleep. Data were collected on community sample 514 adolescents (16–19; 17.7 ± 0.4 years; 50% female) participating in late adolescent examination longitudinal and health. Sleep hygiene daytime sleepiness obtained from reports, behavior caretaker sleep‐wake estimation weekdays wrist actigraphy. Confirmatory...
This White Paper addresses the current gaps in knowledge, as well opportunities for future studies pediatric sleep. The Sleep Research Society's Pipeline Development Committee assembled a panel of experts tasked to provide information those interested learning more about field sleep, including trainees. We cover scope epidemiological and development sleep circadian rhythms early childhood adolescence. Additionally, we discuss knowledge insufficient disruption, addressing neuropsychological...
BackgroundThere is no consensus on reporting light characteristics in studies investigating non-visual responses to light. This project aimed develop a checklist for laboratory-based investigations the impact of physiology.MethodsA four-step modified Delphi process (three questionnaire-based feedback rounds and one face-to-face group discussion) involving international experts was conducted reach items be included checklist. Following process, resulting tested pilot phase with independent...
Chronotype is a construct reflecting individual differences in diurnal preference. Although chronotype has been studied extensively school-age children, adolescents and adults, data on young children are scarce. This study describes its relationship to the timing of circadian clock sleep 48 healthy aged 30-36 months (33.4 ± 2.1 months; 24 males). Parents completed Children's Questionnaire (CCTQ) ~2 weeks before start study. The CCTQ provides three measures chronotype: midsleep time free...
Summary Early childhood represents a time of developmental changes in both sleep and self‐regulation, construct reflecting the ability to control one's behaviour, attention emotions when challenged. Links between self‐regulation processes have been proposed, but experimental evidence with young children is lacking. In current study, we tested effects acute restriction (nap deprivation) on toddlers’ self‐regulation. Healthy ( n = 12; four males; aged 30–36 months (33.9 ± 1.7)) slept strict...
Circadian phase and its relation to sleep are increasingly recognized as fundamental factors influencing human physiology behavior. Dim light melatonin onset (DLMO) is a reliable marker of the timing circadian clock, which has been used in experimental, clinical, descriptive studies past few decades. Although DLMO relationship have well documented school-aged children, adolescents, adults, very little known about these processes early childhood. The purpose this study was 1) describe angles...
Processing speed is an important contributor to working memory performance and fluid intelligence in young children. Myelinated white matter plays a central role brain messaging, likely mediates processing speed, but little known about the relationship between myelination In present study, was measured through inspection times, myelin volume fraction (VFM) quantified using multicomponent magnetic resonance imaging (MRI) approach 2- 5-years of age. Both times VFM were found increase with...
