Internet Gaming Disorder (IGD) has become a prevalent concern among adolescents worldwide, including in India, where approximately 19.4% of adolescents exhibit problematic gaming behaviors. This study investigates the relationship between IGD and proactive aggression among 845 adolescents in Visakhapatnam, aged 14-21 years, using the Internet Gaming Disorder Scale - Short Form (IGDS9-SF) and the Reactive Proactive Aggression Questionnaire (RPQ). Demographic variables including age, gender, and education levels were examined for their influence on IGD and aggression. Results indicated that late adolescents, males and rural residents showed higher levels of both IGD and proactive aggression, while middle adolescents exhibited heightened proactive aggression. Rural and postgraduate students also demonstrated increased aggression, emphasizing the impact of socio-environmental factors on behavioral outcomes. The study highlights the need for targeted interventions to address gaming addiction and aggressive behaviors among adolescents in diverse socio-cultural contexts.
