This research examines participants' social media addictions and self-censorship levels through various variables (age, gender, and perceived academic achievement). The study was carried out with 601 university students from the education faculties of three different universities. Research data were collected through two scales. The first is the 'Social Media Addiction-Adult Form' scale developed by Şahin and Yağcı (2017), and the second is the 'Self-censorship Scale' scale adapted into Turkish by Coşkun, Durak, and Elgin (2008). The Demographic Information Form prepared by the researcher was used for personal information. Statistical analyses such as t-test, One-Way Analysis of Variance (ANOVA), and Pearson Correlation Coefficient were used to analyze the data. The results show that there is a significant relationship between social media addiction and self-censorship. In addition, when analyzed according to self-censorship levels, it was found that social media addiction is higher in people with high self-censorship than in people with low self-censorship. In addition, it was observed that social media addiction increased as perceived academic success decreased. In addition, it was found that there was no significant difference between self-censorship and gender and perceived academic achievement.
