Abstract Study Objectives The objectives of the study were (1) to compare both actigraphy
and questionnaire-assessed sleep quality and timing in children with Smith–Magenis
syndrome (SMS) to a chronologically age-matched typically developing (TD) group and (2)
to explore associations between age, nocturnal and diurnal sleep quality, and daytime
behavior. Methods Seven nights of actigraphy data were collected from 20 children with
SMS (mean age 8.70; SD 2.70) and 20 TD children. Daily parent/teacher ratings of behavior …
