The aim of this work was to investigate the connection between the types of individual video games and the frequency of playing and the symptoms of inattention, hyperactivity and impulsivity and school performance in children with ADHD and those with typical development. The research focus is on children with ADHD, while children with typical development form the control group. Respondents (N=127), parents of children with ADHD and typically developing children of elementary school age, filled out an online questionnaire that, in addition to sociodemographic questions, also contained questions from the SNAP-IV assessment scale for teachers and parents and internal questions that examined habits playing video games in primary school children. The paper used a quantitative approach to data processing. The results of the research indicate that the time spent playing video games in boys with ADHD and boys with typical development does not statistically significantly differ, but that both groups of players spend an average of 2 hours playing video games on weekdays, while boys with ADHD play an average of 2 hours on weekends, and boys with typical development an average of 3 hours. In boys with typical development, a statistically significant positive correlation was found between the intensity of symptoms of inattention and the length of playing video games, and a statistically significant negative correlation between the length of playing video games and school success, while in boys with ADHD, no statistically significant correlation was found on the mentioned variables. Both groups of boys most often played survival action games, followed by massively multiplayer online games (MMORPGs) and sports video games. Typically developing boys who played video games with higher addictive potential, such as massively multiplayer online games (MMORPGs), had statistically significantly higher scores on the hyperactivity and impulsivity subscales of the SNAP-IV rating scale, while no statistically significant difference was found in boys with ADHD. significant difference between the scores on the SNAP-IV rating scale depending on the type of game these boys played most often. The amount of time parents spent in front of a screen on an average day in their free time was not statistically significantly related to the amount of time their children spent in front of a screen on weekdays and weekends. Despite the uniqueness of the territory of the Republic of Croatia, the results of this research should be interpreted with caution given its numerous limitations. As such, this research can bring the problems of the world of video games closer to parents and represent an incentive for all experts who focus on children to continue researching this topic.
