We aimed to determine the relationship between gaming disorder, narcissism, and happiness levels of children between the ages of 9 and 15. This study was based on the compensation theory. The sample consists of 461 boys who continue their education in public schools in Istanbul. In the study, a mixed research design, which nests qualitative data into quantitative, was used. In addition to the scales and sociodemographic form, the Draw-a-Person test was also used to better understand children’s inner world. According to the findings, there is a significant relationship between gaming disorder and narcissism and happiness levels in children. Accordingly, as narcissism increases in children, the gaming disorder level increases, and happiness decreases. We also found a mediation effect in the impact of narcissism on happiness through gaming disorder. According to the results, we think that the problem is not caused by the individual but by society. For a solution, we recommend making more macro-level social work interventions within the framework of system theory instead of the current medical model in combating gaming disorder.
