Why sleep is at the core of children's mental health - Mind the Kids podcast

In this episode of Mind the Kids, the podcast from the Association for Child and Adolescent Mental Health (ACAMH), host Dr. Clara Faria — academic clinical fellow in child psychiatry — is joined by Alina Marinca, PhD student in Psychological Medicine at Queen Mary University of London and clinical psychologist, whose research is funded by the London Interdisciplinary School of Science Doctoral Training Partnership.

Alina shares findings from her JCPP Advances paper  ‘Sleep disturbance as a transdiagnostic marker of children's mental health difficulties: A network analysis of item-level associations between different types of sleep problems and different behavioural and emotional symptoms'.

The study draws on data from the Development of Emotional Resilience observational cohort — a school-based sample of over 500 primary school children aged 7 to 12 from East London, one of the most ethnically diverse and economically deprived urban cohorts in UK child mental health research.

Using network analysis — a powerful statistical approach that maps relationships between symptoms simultaneously — the study examines how specific sleep problems relate to emotional difficulties (anxiety and depression) and behavioural difficulties (hyperactivity, inattention, and conduct problems) in middle childhood, moving beyond the composite sleep scores that have dominated previous research.

The headline finding is striking: sleep anxiety and general anxiety emerge as the most central, influential nodes in the network — sitting at the core of children's emotional and behavioural difficulties and functioning as a transdiagnostic mechanism across multiple mental health conditions. Emotional symptoms were found to be more tightly interwoven with sleep problems than behavioural symptoms, a developmentally meaningful finding with direct implications for how we assess and treat sleep disturbances in primary school-aged children.

Alina and Clara discuss what this means for school-based mental health intervention, why sleep should no longer be treated as a secondary or peripheral feature of child mental health, and how a modular, targeted approach focusing on sleep-related anxiety could benefit children, parents, educators, and clinicians alike. The episode closes with a preview of Alina's next research phase: a longitudinal network analysis tracking whether these core sleep and anxiety symptoms remain stable over time.

Essential listening for anyone working in child mental health, sleep research, school-based intervention, or child and adolescent psychiatry.
