It is thought that with the development and implementation of various programs, young minds will study, socialize, and develop more efficiently. This development will directly affect the development of the country. For this reason, it can be expressed as a need to investigate the concepts with which the loneliness variable is related. At this point, it is important to examine how the mindfulness levels of high school individuals play a role in the relationship between loneliness and social media addiction. For these reasons, it was aimed to examine the mediating role of mindfulness in the relationship between the loneliness and social media addiction levels of high school individuals. The sample of the study, which was designed in the relational survey model, consists of 1115 high school students in various provinces of Turkey. 838 of the students are women and 277 of them are men. Conscious Awareness Scale Adolescent Form, Social Media Addiction Scale for Adolescents and UCLA Loneliness Short Form were used as data collection tools in the study. Two significant findings were reached, and the findings were discussed by comparing them with the literature studies. The first of the findings is that the loneliness level of high school individuals is not a significant determinant according to gender. Secondly, it is the situation in which conscious awareness mediates the relationship between social media addiction and loneliness in high school individuals. In future studies, it is possible to work with individuals from different life stages. The status of individuals can be compared according to their life periods. In this way, loneliness can be better understood. It is thought that the results of this study can support psychological counselors working in schools in managing and directing students' loneliness in a healthy way.
