Commentary: Advancing our understanding of the sleep‐circadian pas de deux for adolescent psychopathology – a reflection on Cooper et al. (2023)

This is an exciting time for research in sleep and psychopathology during the period of adolescence. The study by Cooper et al. (Journal of Child Psychology and Psychiatry, 2023) is a much‐welcome addition to a rapidly accumulating body of work, examining change in eveningness preference throughout adolescence and its prediction of internalizing and externalizing psychopathology. The study has a number of strengths, including a four‐wave longitudinal design, multi‐informant ratings of psychopathology, and an examination of white matter development in a subsample of participants. This commentary discusses the study's strengths and findings, while also providing directions for future research to build on the target article.
