This study aimed to examine internet use in terms of psychological well-being. The descriptive and correlational research designs were used in this study. The data were collected by the online survey. The survey included "Internet Addiction" and "Warwick-Edinburgh Mental Well-being scales" and a "Socio-Demographic Form". Four hundred and twelve people participated in the study. A negative, moderate and significant relationship was found between internet addiction and psychological wellbeing. It has been determined that being under the age of 25, single, unemployed and having a low income are the factors that significantly increase internet addiction. In addition, with the increase in work and income levels, psychological well-being increases significantly. These findings show that individuals under the age of 25, single, unemployed, and in low-income group are in the risk group for internet addiction. As a result, it can be suggested to focus on individuals in the risk group and psychotraining program can be designed for increasing the level of psychological well-being in order to prevent internet addiction.
