Evidence-Based Comprehensive Treatments for Early Autism

TLDR: The empirical studies of comprehensive treatments for young children with autism published since 1998 were reviewed and found that most studies were either Type 2 or 3 in terms of their methodological rigor based on Nathan and Gorman's (2002) criteria.

Abstract: Early intervention for children with autism is currently a politically and scientifically complex topic. Randomized controlled trials have demonstrated positive effects in both short-term and longer term studies. The evidence suggests that early intervention programs are indeed beneficial for children with autism, often improving developmental functioning and decreasing maladaptive behaviors and symptom severity at the level of group analysis. Whether such changes lead to significant improvements in terms of greater independence and vocational and social functioning in adulthood is also unknown. Given the few randomized controlled treatment trials that have been carried out, the few models that have been tested, and the large differences in interventions that are being published, it is clear that the field is still very early in the process of determining (a) what kinds of interventions are most efficacious in early autism, (b) what variables moderate and mediate treatment gains and improved outcomes foll...
