The Adverse Childhood Experiences study highlighted that childhood trauma contributes to health outcomes long into adulthood. This study reframed childhood maltreatment as a public health issue, but there is a risk that this questionnaire will be misused in practice. Assessing the ACEs score of children in schools, child protection or custody is extremely questionable and in this episode we outline our concerns about the misapplication of ACEs. Consider this episode - reverse implementation! A lesson when research SHOULD NOT be applied in practice!
