Change in Sleep Latency as a Mediator of the Effect of Physical Activity Intervention on Executive Functions Among Children with ADHD: A Secondary Analysis from a Randomized Controlled Trial / Xiao LIANG in Journal of Autism and Developmental Disorders, 54-8 (August 2024)

Participants aged 6 to 12 years old with a formal ADHD diagnosis were recruited from a local hospital. A total of 80 eligible children with ADHD were randomized to an intervention group for 12 consecutive weeks of PA training (three times per week, 60 min per session) (n = 40; Mage = 8.37, 75% boys) or a wait-list control group (n = 40; Mage = 8.29, 80% boys). Three core EFs (inhibitory control, working memory, and cognitive flexibility) were assessed by neurocognitive tasks, and sleep quality was measured by the Chinese version of the Pittsburgh Sleep Quality Index. The bootstrapping method was used to test PA intervention effects on EFs and on potential variables of sleep quality after intervention and to test whether there were indirect effects of the intervention on EFs via mediators of sleep. The results showed that the PA intervention had a direct effect on sleep latency reduction (? = ? 0.26, 95%CI ? 0.47 to ? 0.06) and cognitive flexibility improvement (decrease in completion time) (? = ? 0.30, 95%CI ? 0.50 to ? 0.09). Furthermore, change in sleep latency significantly mediated the effects of PA intervention on cognitive flexibility (? = ? 0.084, 95%CI ? 0.252 to ? 0.001). The findings suggest that sleep latency could be a crucial behavioral mediator of PA intervention in improving cognitive flexibility among children with ADHD.

Sleep Problems in Children with ADHD: Associations with Internalizing Symptoms and Physical Activity / Xiao LIANG in Journal of Autism and Developmental Disorders, 56-3 (March 2026)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 56-3 (March 2026) . - p.1163-1172 Titre : Sleep Problems in Children with ADHD: Associations with Internalizing Symptoms and Physical Activity Type de document : texte imprimé Auteurs : Xiao LIANG, Auteur ; Mengping ZHAO, Auteur ; Li SU, Auteur ; Justin A. HAEGELE, Auteur ; Richard H. XU, Auteur ; Jiayue LI, Auteur ; Jinxian GUO, Auteur ; Andy Choi-Yeung TSE, Auteur ; Shirley X. LI, Auteur ; David H. K. SHUM, Auteur Article en page(s) : p.1163-1172 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Children with attention deficit hyperactivity disorder (ADHD) experience high rates of sleep problems and are at increased risk for developing internalizing problems. This study aimed to examine the association of sleep problems and physical activity with internalizing symptoms in children with ADHD. This cross-sectional study included 188 children with ADHD (M age = 8.60 ± 1.38, 78.7% boys). Self-reported questionnaires were used to assess sleep problems (Pittsburgh Sleep Quality Index [PSQI]) and internalizing symptoms (Depression Anxiety Stress Scale 21 [DASS 21]). The presence of sleep problems was defined as a PSQI score > 5. Physical activity was recorded by an ActiGraph GT9X Link accelerometer for 7 consecutive days. In total, 111 children with ADHD presented with sleep problems (59%). Compared with their counterparts without sleep problems, children with sleep problems spent less time in daily moderator-to-vigorous physical activity (MVPA) (F = 15.35, η2 = .079), had a lower proportion of meeting the WHO-recommended 60 min of daily MVPA guideline (F = 9.57, η2 = .050), and showed more internalizing symptoms: depression (F = 10.09, η2 = .053), anxiety (F = 15.84, η2 = .081), and stress (F = 6.98, η2 = .037). BMI, daytime dysfunction of PSQI, and MVPA guideline attainment were significantly associated with internalizing symptoms in children with ADHD. Daytime dysfunction of PSQI is associated with more severe internalizing symptoms, and MVPA guideline attainment may reduce the likelihood of developing depression and anxiety in children with ADHD. Future studies are needed to examine the long-term effects of sleep on internalizing symptoms and the effects of PA-based interventions on sleep and internalizing symptoms in children with ADHD, respectively.

What Ability Can Predict Mathematics Performance in Typically Developing Preschoolers and Those with Autism Spectrum Disorder? / Lijuan WANG in Journal of Autism and Developmental Disorders, 53-5 (May 2023)

The present study first compared the mathematics ability and cognitive abilities of preschoolers with ASD and age-matched typically developing (TD) peers. Then, we examined the relative contributions of cognitive abilities to the mathematics ability of preschoolers with ASD and TD. The results show that compared to those of their age-matched TD peers, the mathematics and cognitive abilities of preschoolers with ASD were impaired. The predictors of mathematics ability were found to differ among preschoolers with ASD and their age-matched TD peers. For TD preschoolers, the domain-specific approximate number system (ANS) was the key predictor of mathematics ability. For preschoolers with ASD, domain-general working memory (WM) was most important.
