The Reliability of the PEP-3 in the Arab Context: Algerian-Tunisian

The objective of this study is to validate the applicability of the PEP-3 in the Arab context (Algerian-Tunisian) within a sample of 116 children with TSA, ranging in age from 2 to 12 years. Between February and August 2024, data were collected from various geographical regions (north, central, and south) in Algeria and Tunisia. The research employed an analytical approach using Cronbach's alpha coefficient along with a descriptive analytical method. The present study examined the effectiveness of the Psychoeducational Profile - Third Edition (PEP-3) in the Algerian-Tunisian environment. The PEP-3 was applied to a sample of 116 children with autism spectrum disorder in Algeria and Tunisia. The construct validity of the PEP-3 was supported by the high internal consistency of each subtest, in addition to the medium to large correlation coefficients between the subtests. The results of the Cronbach's alpha coefficient for the test ranged from 0.93 to 0.94 for the procedural axes. The correlation matrix ranged from 0.71 to 0.95. The findings indicate that the scale in the Algerian-Tunisian context demonstrates an overall stability rate of 0.95. These results provide strong evidence of the construct validity of the PEP-3 and its effectiveness in the Algerian-Tunisian environment.
