Abstract
The purpose of this study was to examine the internal consistency and validity of the Psychoeducational Profile-Third Edition (PEP-3) among children having Autism Spectrum Disorders (ASD) and other ones having Intellectual Disability (ID). This study has involved 44 children, including 30 children affected with Autism Spectrum Disorders (ASD) and 14 children affected by Intellectual Disability (ID). The psychometric evaluation of the PEP-3, in this study, has shown good internal consistency including cronbach's alpha =0.943 for the ten subtests of the performance test and cronbach's alpha = 0.803 for the three subtests of the caregiver's report; thus, indicating the homogeneity of all items in each subtest. The total- domain correlation used to determine the role of each of the PEP3 subtests in relation to the overall measure has shown that all fields contributed effectively to the total score. Therefore, this piece of work, contributes to the educational program planning field in Morocco by validating all subtests of the Performance Test and Caregiver Report (PEP-3) that can help to identify children having ASD and other developmental disorders early and reliably in Morocco.
