["Child and Adolescent Mental Health, EarlyView. ", "\n\nBackground\nIn England, 18% of children and young people (CYP) experience clinical levels of mental health difficulties. CYP who are involved in children's social care, either receiving in‐home care (i.e. child protection plans; CPP) or out‐of‐home care (i.e. children looked after; CLA), may experience higher prevlance than peers. Less is known about actual contacts with mental health services. This study aimed to provide an account of the contacts with mental health services for children with and without CPP and CLA, and reasons for referral.\n\n\nMethods\nData were extracted from NHS Digital for all CYP in England in contact (e.g. through referral, appointment, support) with mental health services between April 2016 and March 2021, and included sociodemographic information, CPP or CLA status and referral reason.\n\n\nResults\nIn total, 1,984,827 CYP were in contact with mental health services. The most common referral reasons were anxiety (13%), ‘in crisis’ (10%) and depression (7%). Contacts tended to increase each year for all groups. Overall, CPP and CLA were between 2 and 3 times more likely to be in contact with mental health services compared to peers. However, this represented between 9% and 18% of CPP and CLA.\n\n\nConclusion\nThe findings suggest that there are wide discrepancies between mental health needs and contacts with services. CPP and CLA have particularly high levels of unmet need. While these data indicate escalating demand, service contacts have not increased significantly, suggesting an increased threshold for access in a stretched clinical service.\n\n"]
