The purpose of this study is to conduct a randomized controlled trial (RCT) to evaluate the efficacy of brief cognitive behavioral treatment for child sleep (CBTcs) to improve sleep in an important high-risk population, overweight/obese (OV/OB) youth with behavioral sleep disorders. OV/OB youth with behavioral sleep disorders and their parent(s) will be randomly assigned to 8 sessions of either CBTcs or an Educational Control (EC). CBTcs will address behavioral sleep issues in children; EC will address sleep and dietary education and general coping strategies. Child sleep (total wake time, total sleep time, bed/wake times), height, weight, physical activity, dietary intake, quality of life (QOL), fatigue, and daytime sleepiness will be assessed at baseline, post-treatment, and 3-month follow-up. It is hypothesized the children in the CBTcs will experience greater improvement in sleep than children in the EC.

Assessment Procedures: Subjects will participate in 8 treatment sessions and 3 full assessment meetings over the course of 7 months. All meetings will be held at the Magnolia Park Sleep Disorders Center. The following procedures will be performed:

Stage 1 - Phone Screening, Stage 2 - Screening and Baseline Measures, Stage 3 - Overnight Sleep Monitoring, Stage 4 - Two weeks Wrist Actigraphy, Sleep Diaries, Dietary Recalls Stage 5 - Intervention, Stage 6 - Post-Treatment Measures, Stage 7 - 3-Month Follow-Up

• 6-12 years of age
• Prepubescent
• Have a body mass index ≥85th percentile for age and gender norms as published by the CDC, and
• Accompanied by a parent or legal guardian that lives in the same home as the child. The parent must be able to read and understand English at the 5th grade level.

Exclusion Criteria:

• Sleep Apnea: previous diagnosis or an apnea/hypopnea index (AHI) >10 according to PSG.
• Periodic Limb Movement Disorder (PLMD): previous diagnosis or myoclonus arousals per hour >5 according to PSG.
