The rapid growth of social networking websites has significantly influenced the daily lives, behaviors, and interpersonal interactions of college students. While these platforms provide opportunities for communication and self-expression, excessive use may lead to addictive patterns. At the same time, personality traits such as narcissism, characterized by self-focus and a strong need for admiration, may shape individuals’ online behavior. The present study aimed to examine the relationship between social networking website addiction and narcissism among college students, along with gender differences in these variables.
