Year: 2011
Type: dissertation
Study design: Observational Study
Abstract: This study explored the relation between chronotype and cognitive and behavioral problems in 333 school-aged children (mean age 9.97 years, 55% girls), with an important focus on a potential mediating role of sleep duration and sleep quality. Participants completed short-form WISC-IIINL and several tasks on the Amsterdam Neuropsychological Tasks (ANT), which assesses important domains of attention. Their parents filled out a sleep log and several questionnaires regarding chronotype (CCTQ), sleep habits (CSHQ), and behavioral problems (CBCL). Results showed that indeed eveningness was associated with behavioral problems. No direct associations with cognitive functioning were found. Sleep duration was not associated with cognitive-behavioral functioning. Sleep quality, specifically feeling rested in the morning during weekdays, was associated with cognitive and behavioral functioning. Several mediating relations were identified. The findings highlight that sleep quality partially mediates the relation between chronotype and cognitive-behavioral problems. Evening types show behavioral problems when they do not feel rested in the morning. These findings have significant clinical implications.
