The Relationship Between Autistic Traits and Sleep Chronotype in Children and Adolescents with ADHD

This study examined associations between chronotype (sleep-wake preferences), autistic traits, and psychiatric symptoms in 97 children/adolescents with ADHD using standardized parent and child questionnaires. Chronotype showed significant positive correlations with depressive symptoms, social phobia, separation anxiety, and ADHD symptoms, with depressive symptoms and oppositional behaviors predicting chronotype preferences in regression analysis.
