Predicting progress in Picture Exchange Communication System (PECS) use by children with autism (short summary)


The Picture Exchange Communication System (PECS) is a communication system designed mainly for use by non-verbal children with autism. It has generally been found to have positive outcomes in a range of areas, including social communication skills, decrease in challenging behaviour and possible increases in the use of spoken language. However there is limited information available to support professionals to make predictions about the amount of progress individuals might make using PECS.

In this study retrospective analysis was used to look into whether children’s Total Developmental Age (TDA) scores on the Psycho-Educational Profile-Revised (PEP-R) before intervention could predict the progress children aged 5 to 6 with autism towards using PECS at level 3.

The findings indicated that children who had a TDA of over 16 months achieved success at PECS level 2, those with a TDA of 16 months or less did not.

The authors concluded that assessment of the developmental level of children with autism who are being considered for the introduction of PECS might give useful information about the likely degree of progress.
