Prospective analyses revealed depressed mood predicted less total sleep time on school nights and a longer latency to sleep onset on weekends 1 year later.There was no prospective support Set Screw for sleep predicting later depressed mood.Conclusion: Contrary to prediction, our results suggest in this case that depressed mood may act as a precursor to poor sleep rather than the converse.Keywords: adolescence, sleep disturbance, school-based, prospective, depressive symptoms.
