The STADIA (Standardised diagnostic assessment tool as an adjunct to clinical practice in child and adolescent mental health services) project is a multicentre randomised controlled trial to investigate if the use of a standardised diagnostic assessment tool improves the detection and treatment outcomes of emotional disorders in young people within Child and Adolescent Mental Health Services (CAMHS) (trial led by Nottingham).

The aim of the study is to evaluate the clinical and cost effectiveness of a standardised diagnostic assessment (SDA) tool, as an adjunct to usual clinical care, on clinician diagnosis of emotional disorders in children and adolescents (aged 5-17 years) presenting with emotional difficulties referred to CAMHS.

Several standardised diagnostic assessment tools exist that have evidence of reliability and validity. The NICE Quality Standards for depression and anxiety state that diagnostic assessment tools may be helpful in the formal assessment of depression and anxiety disorders in young people. However, experts state that these tools are not routinely used at initial assessments in CAMHS.

The SDA tool to be assessed is the DAWBA (Development and Well-Being Assessment).

The trial will be led by a multi-disciplinary team with expertise in designing and successfully conducting clinical trials in child and adolescent mental health. The team consists of national experts in child and adolescent emotional disorders, medical statistics, trial management and delivery, health economics, healthcare technology, qualitative research and implementation research. The NIHR MindTech MedTech Co-operative will provide expertise and lead the work on usability and PPI.
