Autism spectrum disorder in under 19s: support and management

What is the value of a key worker approach (defined by protocol and delivered in addition to usual care) for autistic children and young people in terms of parental satisfaction, functioning and stress and child psychopathology?

Is a group-based parent training intervention for parents or carers of autistic children and young people clinically and cost effective in reducing early and emerging behaviour that challenges in the short- and medium-term compared with treatment as usual?

What is the comparative clinical and cost effectiveness of pharmacological and psychosocial interventions for anxiety disorders in autistic children and young people?

Are comprehensive early interventions that combine multiple elements and are delivered by parents and teachers (for example, the Learning Experiences – an Alternative Program for Preschoolers and their Parents [LEAP] model) effective in managing the core features of autism and coexisting difficulties (such as adaptive behaviour and developmental skills) in pre‑school children?
