This study was conducted to examine the relationships between high school students' social anxiety level and emotion regulation strategies and parental attitudes. 323 students studying at different types of high schools in Diyarbakır in the 2019-2020 academic years participated in the present study using the relational screening model. In the research, "Social Anxiety Scale for Adolescents", "Child Rearing Attitudes Scale", "Adolescent Emotion Regulation Questionnaire (AERQ)" and a personal information form prepared by the researcher were used. Descriptive statistics were explained in the analysis of the data, and the Pearson product-moments correlation coefficient and hierarchical regression analysis were used. According to the results, the model formed by the strict supervision / control attitude of the parents and the internal dysfunctional emotion regulation strategies used by adolescents predicts social anxiety, and the related variables can be risk factors for social anxiety in adolescence.
