TEACCH is a 'whole life' approach aimed at supporting children, adolescents, and adults with autism through the provision of visual information, structure, and predictability. The results of a small number of studies have indicated positive outcomes for children who access the TEACCH program. However, there is a need for larger, systematic and controlled studies to be conducted by independent researchers in order to evaluate the immediate and long term outcomes of the program.
LEAP is a comprehensive preschool service, designed for both children with autism and typically developing children. LEAP has the components of an integrated preschool program and a behaviour skills training program for parents. The program contains aspects of behavioural analysis, but it is primarily a developmentally based approach. Long term outcomes are currently being evaluated however independent evaluation is required to determine effectiveness.
'More than Words' is an intensive training program for parents of pre-school children with autism. The program derives its theoretical framework from a social-pragmatic developmental perspective and emphasises the blending of aspects of both behavioural and naturalistic child-centred programs; the breaking down of activities into structured, small steps found in an ABA program, and the provision of opportunities to use language for functional purposes built into more naturalistic approaches. A preliminary evaluation of treatment outcomes has indicated that the program has some positive outcomes for children and families. Further research is required in order to evaluate this program more comprehensively.
