A retrospective study was(More)
The current study investigated the link between poor sleep and ADHD symptomatology. The effects of extending versus restricting sleep on subjective (questionnaires) and objective (actigraphy) measures of daytime movement were examined in 25 typically developing children aged 8-12 years. Subjective measures demonstrated an increase in ADHD symptomology(More)
The Behavior Rating Inventory of Executive Functioning (BRIEF) has been widely used both clinically and in research for measuring executive functioning (EF) in children with attention-deficit hyperactivity disorder (ADHD). This study examined the concurrent validity of the BRIEF (both parent and teacher ratings) compared to performance-based measures of EF(More)
OBJECTIVE Better Nights/Better Days, a distance intervention for insomnia in school-aged children (with and without attention-deficit/hyperactivity disorder [ADHD]), was evaluated to determine its effectiveness on children's sleep and psychosocial functioning.  METHODS  A single center, parallel group design randomized controlled trial (stratified on ADHD(More)
