The Internet, which is one of today's most important technologies, has become an integral part of our lives. The fact that the internet, which surrounds our four sides, is addressing to all age groups also extends the user profile. The fact that adolescents are keen users of the internet and their excessive use of the internet lead to problematic usage of the internet. This is an issue that needs to be addressed with precision. The aim of this research is to determine the social work interventions that can be applied at the macro level to reveal the reasons of problematic internet usage and the solutions that will contribute to the elimination of these reasons in secondary and high school students. Eight secondary schools and 599 high school students from the center of Kocaeli Province were selected as representatives from secondary and high schools. "Problematic Internet Usage Scale-Adolescent" developed by Ceyhan, Ceyhan and Gurcan (2009) was used to determine problematic internet use of students. The data obtained from the questionnaire was interpreted by SPSS with basic descriptive statistics, T-Test, Anova and Single and Multiple Regression Analysis techniques. As a result, the following findings have been obtained in the research. Secondary school and high school students in the city center of Kocaeli, who spend more than 3 hours on the internet on average, use the internet mostly for social media, chatting, watching and uploading series, films, or videos. According to the Problematic Internet Usage Scale with 92.7% reliability, two thirds of the students are normal internet users and one third is composed of problematic and under-risk internet users. In terms of gender variable, boys have more problematic internet usage than girls, and in terms of age variable, those in the age range of 13-15 have more problematic internet usage than those over 16 years of age. According to the established linear regression models, as the daily time spent on internet, social media and digital games increases, the probability of problematic internet usage also increases.
