| Abstract |
The Picture Exchange Communication System (PECS) is a communication program that has become widely used, especially with children with autism. This paper reports the results of a review of the empirical literature on PECS. A descriptive review is provided of the 27 studies identified, which included randomized controlled trials (RCTs), other group designs and single subject studies. For 10 appropriate single subject designs the percentage of nonoverlapping data (PND) and percentage exceeding median (PEM) metrics were examined. While there are few RCTs, on balance, available research provides preliminary evidence that PECS is readily learned by most participants and provides a means of communication for individuals with little or no functional speech. Very limited data suggest some positive effect on both social-communicative and challenging behaviors, while effects on speech development remain unclear. Directions for future research are discussed including the priority need for further well-conducted RCTs. |

Attention Score in Context
This research output has an Altmetric Attention Score of 6. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 31 May 2022.
All research outputs
#5,747,565
of 23,867,274 outputs
Outputs from Journal of Autism and Developmental Disorders
#2,003
of 5,240 outputs
Outputs of similar age
#21,849
of 116,937 outputs
Outputs of similar age from Journal of Autism and Developmental Disorders
#15
of 35 outputs
Altmetric has tracked 23,867,274 research outputs across all sources so far. Compared to these this one has done well and is in the 75th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 5,240 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 13.2. This one has gotten more attention than average, scoring higher than 60% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 116,937 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 73% of its contemporaries.
We're also able to compare this research output to 35 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 57% of its contemporaries.
