Standardization of Adapted Picture Exchange Communication System (PECS) For Children with ASD in Pakistan
The current experimental research aimed to standardize the adapted version of PECS for autistic children in Pakistan. The Adapted PECS was standardized by an experimental study on autistic children and normal children. As an adequate sample size of autistic children was difficult to collect, so a sample of normal children was also taken along with autistic children for standardization of PECS in Pakistan. Primary data was collected by deploying simple random sampling (sample of 70 normal children) and convenience sampling (sample of 30 autistic children). Statistics used to determine reliability and validity. An adapted version of PECS justifies the criteria of a suitable sample size, concurrent validity, predictive validity, measures of central tendency and variability, test-retest reliability, and inter-rater reliability. The data analysis results illustrated that adapted version of PECS is a valid and reliable tool to be managed in Pakistan for autistic children
