The aim of this study was to determine the effectiveness of positive development youth education to parents on the quality of the perceived parent-adolescent relationship and was done by quasi-experimental method with pre-test and post-test and control group. The study population was the first grade high school students in Tehran's District 1 and the sample consisted of 30 girls aged 12 to 17 years (15 in the experimental group and 15 in the control group) in 2020-2021. The mothers of the experimental group participated in a positive adolescent transformation training program during 12 two-hour sessions. The data collection tool was the Alabama (2001) Parent-Child Relationship Quality Questionnaire. Data were analyzed using SPSS 24 software and analysis of covariance. The results showed that there was a significant difference between the experimental and control groups in positive parenting scores, punishment and father participation (P> 0.05). The mean post-test scores of the experimental group increased significantly in the components of positive parenting and father participation and decreased significantly in the component of punishment, which indicates the effectiveness of teaching positive youth development to parents on the quality of the parent-adolescent relationship. Emphasis on the components of positive development can be a good practical program to improve and enhance the quality of the perceived parent-adolescent relationship.
