• Abstract Objective /background : Few adolescents report obtaining adequate amounts of sleep. Correlational studies have linked adolescent short sleep with driving crashes and sluggish cognitive tempo (SCT), a cluster of symptoms that include sluggishness and low persistence which are related to but distinct from inattention and sleepiness. The relationship between SCT and driving is understudied and no study has experimentally examined the relation between SCT and sleep. We examined the relationship between SCT and driving problems in a sample of chronically short-sleeping adolescents. We also examined whether experimentally extending sleep improved SCT and driving behaviors. Participants /Methods : Licensed 16-18-year-olds who regularly obtain 5-7 hours of sleep completed a 5-week at-home experimental protocol: a baseline week to determine typical sleep (TYP), followed in counterbalanced order by 2-week spans in which school-night bedtimes and rise times were (a) matched to TYP, or (b) modified to extend (EXT) time in bed by 1.5 hours/night. Sleep was monitored via actigraphy. Self- and parent-reported SCT and inattention, as well as self-report of driving problems, were obtained at baseline and following each condition. Of the 38 eligible participants who completed the baseline session, 24 completed all 5 weeks. Results After controlling for inattention, only parent-reported SCT was significantly positively associated with self-report of purposeful driving violations at baseline. Adolescents reported less SCT during EXT than TYP. Also after controlling for inattention, participants who reported improvement in SCT demonstrated fewer driving problems during EXT than during TYP. Conclusions Preliminary findings suggest that extending sleep in short-sleeping adolescents may help alleviate SCT symptoms and improve driving.
