Pengaruh antara Dimensi Big Five Personality terhadap Self Disclosure

Abstract. The development of social media has transformed the way individuals express themselves, including through Instagram second accounts, which provide greater privacy. This phenomenon is widely utilized by Generation Z for self-disclosure or sharing personal information. This study aims to examine the influence of the Big Five Personality dimensions (extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience) on self-disclosure behavior among Instagram second account users, and to explore gender differences in these patterns. A quantitative approach with causal-comparative methods was employed. The sample was obtained using convenience sampling, comprising 466 Generation Z respondents aged 18–24 years. Data were collected using the Big Five Inventory-2 (BFI-2) and the Revised Self-Disclosure Scale (RSDS) and analyzed through multiple linear regression and difference tests. The findings indicate that all five personality dimensions simultaneously have a significant effect on self-disclosure (R² = 0.317; p < 0.001), with neuroticism emerging as the dominant predictor. Difference tests show no significant gender differences in the level of self-disclosure, but the dominant personality dimension varies by gender: openness to experience among males and neuroticism among females. These results highlight the role of personality in shaping self-disclosure behavior on Instagram second accounts and suggest that privacy features reduce gender-norm pressures, making behavioral differences between men and women less apparent.
