In this episode of Mind the Kids, the podcast from the Association for Child and Adolescent Mental Health (ACAMH), host Clara Faria, academic clinical fellow in child psychiatry, is joined by Dr. Tessa Reardon, research fellow in the departments of experimental psychology and psychiatry at the University of Oxford. Dr. Reardon shares findings from her recently published paper in JCPP, the Journal of Child Psychology and Psychiatry, co-authored with colleagues. Drawing on the My Cats cluster randomised controlled trial, the study recruited children aged four to seven identified as being at heightened risk for anxiety disorders through schools across England. The intervention — known as OSI (Online Support and Intervention for Child Anxiety) — is a parent-led, therapist-supported online cognitive behavioural therapy programme, in which parents work through digital modules of approximately 20 minutes each, supported by brief telephone or video calls with a children's wellbeing practitioner, amounting to around two and a half hours of contact time in total. The research sits against a backdrop of a growing gap between the need for child mental health support and access to evidence-based care. CAMHS thresholds are high, and many families cannot access help until difficulties are already entrenched — yet anxiety disorders in children can onset as early as age five and a half. Schools offer a distinctive opportunity to reach families before problems escalate, and England's Mental Health Support Teams (MHSTs) represent a trained, scalable future workforce for delivering this type of early intervention in child mental health. The primary outcome — anxiety disorder diagnosis at 12 months — showed fewer diagnoses in the intervention group, though the difference did not reach statistical significance. All secondary outcomes were statistically significant, however, including reductions in child anxiety symptoms, inhibited temperament, parental anxiety, and targeted child and parent behaviours. Approximately three quarters of families completed the programme — a notably strong completion rate for a school-recruited, at-risk population who were not actively help-seeking. Qualitative findings, forthcoming, point to broader ripple effects within families beyond the targeted outcomes. Clara and Tessa discuss why schools were chosen as the recruitment setting; why the integrated practitioner calls in therapist-supported online CBT appear central to completion rates compared with fully self-guided approaches; and what the findings mean for scaling school-based mental health intervention. The conversation also turns to a key challenge ahead — addressing inequalities in participation, particularly among families from socioeconomically disadvantaged backgrounds, to ensure the benefits of parent-led CBT reach those who need them most. A must-listen for anyone working in child anxiety prevention, early intervention, school-based mental health, CBT for young children, CAMHS, or child and adolescent mental health.
