Since the report on educating young children with autism from the National Research Council (2001), we have known that for many—though not all—preschoolers with autism evidence-based interventions with slightly older preschool children are associated with improved outcomes. As the NRC report noted, the programs evaluated all had some degree of evidence base, and the program used in the current study was built on Dr. Roger’s model (see Rogers et al. 2012). The results suggest that with earlier identification and a developmentally informed treatment of relatively low intensity significant gains can be made early in life when it seems likely that the potential for change is greatest.
The paper does raise other issues that should be mentioned, at least in passing. One is the issue/problem of early diagnosis, which may be less reliable until children approach their third birthday (Chawarska et al.2014). Data on the crucial issue of early diagnosis and risk assessment have been somewhat conflicting (Chawarska et al. 2012; Ozonoff et al. 2010), perhaps reflecting differences in methods used. Although even significant risk for autism is clearly enough to prompt clinical attention, it will be important to implement innovative approaches to assessment of risk in this young population. While implementation of screening tests/checklists remains important the development of more performance based approaches will be of great interest (Volkmar et al. 2014a).
Finally, and perhaps somewhat paradoxically, this paper focused on young children also should remind us of the need to focus on adolescents and adults with autism or a history of autism. Early intervention seems to be significantly improving the outcomes for many individuals who are now going to college and becoming more independent adults (Fein et al. 2013); however, at the same time, vulnerabilities may persist in various areas, including adaptive and social skills as well as potentially increased risk for some mental health problems (Volkmar et al. 2014b). Although potential supports are available (Brown 2010), many gaps remain in our knowledge with few data on issues like employment and mental health status and need (Piven et al.2011). It is clear that work across the entire age span is critically needed.
