Editorial: What the Future Holds for Psychological Treatments in Youth: Long-term Perspectives on Sleep and Circadian Interventions.

Youth represents a vulnerable developmental period associated with significant sleep and circadian changes. One notable change is increased eveningness, which refers to a tendency for later sleep and daily activities. Eveningness has been associated with various adverse outcomes in youth, including compromised sleep, mental health, and physical well-being.^1,2 As such, it is imperative to develop effective interventions to address these issues. While some evidence suggests short-term benefits of interventions targeting circadian problems,³ the extent of our knowledge regarding the long-term impact on youth remains uncertain. In this issue of the Journal, Susman et al.⁴ shed light on this crucial question through their study that examined the effects of the Transdiagnostic Sleep and Circadian Intervention for Youth (TranS-C), a modular cognitive-behavioral intervention that specifically targets sleep and circadian issues.
