This study aimed to investigate the effect of a Positive Parenting Program (Triple-P) on the interaction of the mother-adolescent with intellectual disability. The pre-test and post-test randomized experimental design was used for this research. Thirty-four mothers of adolescents with intellectual disability took part in the present research and were assigned to experimental and control groups, each comprised of 17 people. The experimental group took part in an 8-session Triple-P and each session lasted 75 minutes, but the control group did not participate in this intervention. The data were analyzed using MANCOVA. The findings revealed that Triple-P intervention significantly influenced dependency, closeness, conflict, and positive interaction between the mother and the child with intellectual disability. The present study emphasized that Triple-P will improve the interaction of mother-adolescent with intellectual disability; therefore, Triple-P is a useful intervention.
