Background: ADHD is highly comorbid with Delayed Sleep Phase Syndrome (DSPS). Both are associated with obesity and diabetes, which can be caused by long-term dysregulations of appetite and glucose metabolism. This study explores hormones involved in these processes and the effects of chronotherapeutic interventions in a small sample of adults with…

Background: Sleep problems are common in adults with ADHD and may be bidirectionally associated with ADHD severity and other psychiatric symptoms. We investigated the prevalence of positive screenings for various sleep disorders, and their association with psychiatric comorbidities in a large sample of adults with ADHD from a specialized…

Background: Gaining insight into sleep-wake patterns of persons with intellectual disabilities is commonly done using wrist actigraphy. For some people, contactless alternatives are needed. This study compares a contactless bed sensor with wrist actigraphy to monitor sleep-wake patterns of people with moderate to profound intellectual…

This randomized controlled trial (NTR5697) examined the effects of a 5-week daily skin-to-skin contact (SSC) intervention, compared with care-as-usual, on full-term infant crying and sleeping duration during the first 12 weeks postnatally (secondary outcomes of this trial). This trial included 116 Dutch healthy mothers and their full-term infants.…

Background: The psychological well-being of students may be especially affected by the COVID-19 pandemic; international students can lack local support systems and represent a higher risk subgroup. Methods: Self-reported depressive symptoms, suicidal ideation, anxiety, post-traumatic stress disorder (PTSD), insomnia, alcohol use, academic stress,…

One of the earliest challenges for infants and their parents is developing a diurnal sleep--wake cycle. Although the human biological rhythm is circadian by nature, its development varies across cultures, based in part on "zeitgebers" (German: literally "time-givers") or environmental cues. This study uses the developmental…

This study examined how top-down control influenced letter-speech sound (L-SS) learning, the initial phase of learning to read. In 2020, 107 Dutch children (53 boys, M[subscript age] = 106.845 months) learned eight L-SS correspondences, either preceded by goal-directed or implicit instructions. Symbol knowledge and artificial word-reading ability…

This systematic literature review examines the relationship between restricted and reduced sleep and school performance, learning and cognitive functioning in typically developing adolescents. Correlational and experimental data were evaluated from 17 studies which included participants ranging from 11 to 19 years in studies from seven countries…

Background: This study evaluated the effect of the school-based intervention Charge Your Brainzzz on adolescents' social-cognitive determinants, sleep hygiene and sleep duration and quality. Methods: A cluster-randomized controlled trial was conducted with 972 students from 10 Dutch high schools. Schools were randomly allocated to the intervention…

We tested whether adoptive parenting played a role in the association between pre-adoption experiences and children's adaptive (responsiveness) and maladaptive (internalizing and externalizing behavioral problems, attention and sleep problems) behavioral adjustment over time. Ten-year-old girls, adopted at 13 months from institutional care (n =…

The seven papers in this issue address a variety of challenges that parents in several different cultural places encounter as they do their best to ensure their children's safe, happy, and successful development from infancy through middle childhood: infant sleep, developmental agendas, temperament, preschools, academic success, and learning to be…

Learning is crucial for everyone. The association between biological (eg, sleep, nutrition) and psychological factors (eg, test anxiety, goal orientation) and learning performance has been well established for children, adolescents and college students in traditional education. Evidence for these associations for adult distance students is lacking…

Over the past century, technological development and better access to services has resulted in significant improvements to quality of life. Despite this, however, levels of stress, anxiety and depression are rising. Education can play a role in supporting well-being during and beyond schooling. Schools are increasingly concerned not only with…

Background: The Actiwatch is increasingly being used to investigate sleep. The aim of this study was to investigate which sensitivity setting of the Actiwatch is most suitable to detect sleep disturbance in older adults with intellectual disability (ID). Method ;Two Actiwatch types were compared to polysomnography (PSG) in 10 older adults with…

Objective: The authors explored associations between ADHD symptoms, seasonal depressive symptoms, lifestyle, and health. Method: Adult ADHD patients ("n" = 202) and controls ("n" = 189) completed the ASESA questionnaire involving lifestyle, eating pattern, and physical and psychological health, and validated measures on ADHD…
