Attention, Behaviour, and Sleep

Attention, Behaviour, and Sleep laboratory
A considerable proportion of children and adolescents do not experience adequate sleep. Clinical studies show that poor sleep is implicated in the development and persistence of very prevalent childhood disorders affecting youth health. Dr. Gruber’s work seeks to examine the mechanisms underlying the association between sleep and mental and physical health, and to use the knowledge gained from her research to develop evidence-based interventions to improve youth mental and physical health. Her research focuses on three themes as they relate to pediatric sleep: ADHD, academic performance, and obesity. Additionally, Dr. Gruber translates her research findings into tools for healthcare providers and educators, to promote healthy sleep in children and adolescents by creating evidence-based resources to optimize the care of children with sleep disorders.

1. Sleep and ADHD
The objective of this part of Dr. Gruber’ research program is to characterize the sleep abnormalities of ADHD to explore potential behavioral, circadian, and genetic contributions of such abnormalities and to measure the impact of poor-quality sleep on the daytime functioning of children with ADHD. Using this knowledge, she seeks to develop evidence-based approaches to prevent or treat the daytime problems caused or exacerbated by sleep deprivation in children with ADHD

In terms of knowledge translation, Dr. Gruber has contributed to creating recommendations on clinical practice guidelines for the diagnosis and evaluation of sleep problems in children with ADHD.

2. Sleep and Academic Performance
The objective of this part of Dr. Gruber’ research program is to is to discover mechanisms underlying the association between sleep and academic performance. Dr. Gruber is investigating the role of sleep in IQ, academic performance and the daily functioning in school of typically developing children.

In terms of knowledge translation, Dr. Gruber and her team have developed the Sleep For Success program. This program is the first school-based intervention that seeks to improve children’s academic performance and overall health by extending their sleep.

3. Sleep and Obesity
The objective of this this this part of Dr. Gruber’ research program is to examine the association between sleep and eating behavior and obesity. Dr. Gruber focuses on investigating psychological moderators of the associations between sleep and eating/obesity, such as self-control.

In terms of knowledge translation, Dr. Gruber has developed Healthy Nights and Healthy Days – a multi-component, school-based intervention for the prevention of childhood obesity that addresses the interplay between sleep and physical activity and sedentary behavior.

Sleep Education and Dissemination of Evidence-Based Practice
Dr. Gruber has developed a comprehensive framework for sleep promotion and prevention programs for psychologists, pediatricians, and schools professionals.
In addition to her two school-based programs, Dr. Gruber has produced the following translational tools:
