ABSTRACT
Background: There is an increasing recognition ofeffectiveness of one to one intervention for autistic childrenbefore age of 6 years old. Our objective was to explore theimportance of early detection and early intervention by one toone maneuver.Methods: We studied 100 children aged divided into twogroups of children, each group composed of 50 autisticchildren. The first group aged 22months- 6years old and hadreceived 15-20 hours a week of the intervention – one to onesessions of comprehensive early intervention program, whilethat of the second group aged 6 – 12 years old and werealready receiving group -based programs of intervention.Autism spectrum disorder was diagnosed clinically by DSM-Vthen participants were assessed before and after interventionby CARS-2-ST and by Vineland Adaptive Behaviours Scales–Second Edition (VABS-II) that was conducted by a licensedpsychologist.Results: As regard the first group Statistically significant postintervention improvements were found in children’sperformance on their overall intellectual functioning andsignificant increases in their child’s communication,socialization, daily living skills and motor skills on the VABS-II,and a significant decrease in autism-specific features on theCARS scale. Nonetheless, these results are different from thesecond group as showed mild improvement statistically nonsignificant.Conclusion: Our results in children indicated a significantrelationship between early intervention of one to one sessionsand prominent improvement. However, the late intervention bygroup based session’s revealed unapparent improvement.
