Prevalence and correlates of poor sleep among adolescents.

The Stanford Sleep Inventory was given to 639, 11th- and 12th-grade students to assess the prevalence and correlates of poor sleep among an adolescent population. Of the sample reported, 49.8% had no sleep problems, whereas 37.6% reported occasional sleep disturbance and 12.6% reported chronic and severe sleep disturbance. Students complaining of disturbed sleep were more likely than good sleepers to describe negatively their physical and personality characteristics. The clinical implications of these data for developing educationally-based nondrug treatment of the complaint of insomnia among adolescents are discussed.
