​This study investigates the impact of social media usage patterns on multiple dimensions of political efficacy. Using Structural Equation Modeling (SEM) in JASP software (version 0.95.2), the analysis draws on a sample of 478 university students. It examines the relationships between three types of social media use – active social, active non-social, and passive – and four dimensions of political efficacy: internal, external, political interest, and perceived political treatment. The model also tests the moderating effects of variables such as gender, educational level, and academic specialization. The results indicate that active social use has a strong, statistically significant positive effect on both internal efficacy and political interest, but a strong negative effect on external efficacy and perceived political treatment. Active non-social use shows no significant effect across any of the examined dimensions. In contrast, passive use is associated with significant negative effects on all examined dimensions of political efficacy. Regarding moderating variables, gender and academic specialization do not produce significant effects, whereas educational level significantly moderates the relationship between social media usage and political efficacy.​​​​
