Latent Profiles of Sleep Disturbance and Impairment in Elementary School-Age Youth: Concurrent and Longitudinal Associations with Emotional, Behavioral, and Academic Functioning.

Objective: The links from youth sleep problems to emotional, behavioral, and academic functioning are well documented. Latent variable mixture modeling (LVMM) has been used to explore these relations; however, additional research is needed in diverse samples and with self-reports of sleep-related difficulties. The objectives of the current study were to identify profiles based on patterns of sleep disturbance and impairment and explore associations among profiles and functioning at baseline and over a subsequent 6-month period.
