Abstract
Adolescent sleep deprivation is a pressing public health issue in the United States as well as other countries. The contexts of adolescents' lives are changing rapidly, but little is known about the factors that adolescents themselves believe affect their sleep. This study uses a social-ecological framework to investigate multiple levels of perceived influence on sleep patterns of urban adolescents. Data were drawn from interviews and surveys conducted in three California public high schools. Most participants identified homework as their primary barrier to sleep, particularly those engaged in procrastinating, multitasking, or those with extracurricular demands. Results indicate that the home context has important implications for adolescent sleep, including noise, household rules, and perceived parent values. These findings identify important areas for future research and intervention, particularly regarding the roles of parents.
