This study explores the relationships between selfie posting frequency, narcissistic tendencies, and self-esteem among males and females on social networking sites A sample of 100 participants from Peshawar, consisting of 50 males and 50 females, was surveyed using the Rosenberg Self-Esteem Scale (1965) and the Narcissistic Personality Inventory (1976). Analysis of the data revealed that males post selfies more frequently than females, supporting the first hypothesis. Contrary to the second hypothesis, the results showed that males exhibit significantly higher narcissistic traits compared to females. Additionally, self-esteem scores did not significantly differ between genders, which contradicts the third hypothesis. These findings suggest that while there are differences in selfie posting frequency, narcissistic tendencies and self-esteem do not show significant gender-based differences in this context. The results have implications for understanding gender differences in social media behaviors and their psychological impacts.
