A very good starting point for comparing different interventions is the Raising Children Network’s ‘Parent Guide to Therapies‘ which provides a description of the most commonly used interventions in Australia, as well as a rating for research evidence, time commitment required, and cost. Research Autism, based in the UK, provides a similar service and is also well worth a look.
Even when we consider only those interventions for which there is good research evidence, we find that there is currently no single best intervention which works equally well for all children with autism. This is no doubt due in large part to the fact that the individual skills and needs of each child, and his or her family, are unique.
