Abstract
Autism Spectrum Disorders, or ASD, is a disorder that affects about 1.4% of children in the United States. Individuals with ASD have difficulty with social cues, eye contact, communication, and engagement with others. The author reviewed literature from 2010-2015 to fill in the gaps left by previous meta-analyses and more specifically to examine the fidelity of implementation and the PECS training. Two methods were used to examine and analyze the selected studies in this quantitative synthesis. Those two methods included analysis of moderators using a linear regression and analysis of effect size using Cohen's d. When using the following search terms 496 articles were yielded initially. The terms were PECS, Picture Exchange Communication System, Autism, Training, Fidelity of Implementation, and Picture Exchange. When the author changed the term autism to ASD, 508 results were yielded; showing that the terms autism and ASD are used interchangeably. The total number of studies (k) selected for the analysis was 19. The author calculated the weighted average effect size for randomized experiment effects corrected for sample size as d= .339 (Small) for the single case study designs as d=.815 (Large). The results from the moderator analysis showed that having training in the PECS greatly increased its effectiveness, however, no results could be concluded about fidelity of implementation as the selected studies did not contain data about this moderator. These findings suggest that practitioners implementing the PECS should have training on the intervention. Additionally, researchers should include data on the fidelity of implementation of the PECS.
