Background and Purpose: The parenting style has a significant impact on many aspects of children's lives. The aim of this study was to investigate the effectiveness of the positive parenting education based on Sanders' approach on happiness and parent-child conflict of students.

Method: ط The research method is semi-experimental with pre-test, post-test design with control group. The statistical population consisted of all male secondary school students in Shiraz during the academic year of 2016-2017. Using a multi-stage sampling method, 30 mothers whose children had low score in the happiness and a high score in parent-child conflict, were selected and assigned into experimental and control groups randomly. Data were collected by Oxford Happiness Inventory (Argyll and Levy, 1990) and Strauss's parent-child conflict questionnaire (1996). The positive parenting style was taught to the experimental group in 8 sessions. Data analysis was performed by using covariance analysis.

Results: The results showed that positive parenting education based on Saunders' approach had a significant effect on increasing happiness and reducing parent-child conflict in students (P< 0.05).

Conclusion: Overall, the results of this study confirm and emphasize the usefulness of positive parenting education because of its role in health and happiness and reduction of parent-child conflict.
