Abstract

Instagram has become an important medium for students’ self-expression and social interaction, yet its relationship with self-confidence in interpersonal communication remains an important area of investigation. This study examines the relationship between Instagram use intensity and students’ self-confidence in interpersonal communication. A quantitative cross-sectional survey was conducted among 48 active students from the Communication Studies Program at Universitas Sumatera Utara, cohorts 2022–2024, selected through purposive sampling. Eligible respondents had used Instagram for at least one year and reported an average use of at least three hours per day. Data were collected using a validated and reliable Likert-scale questionnaire and analyzed using simple linear regression with SPSS version 26. The results showed a positive and statistically significant relationship between Instagram use intensity and students’ self-confidence in interpersonal communication (F = 74.316, p < 0.001). The model explained 61.2% of the variance in self-confidence (R² = 0.612). These findings indicate that higher Instagram use intensity is statistically associated with higher self-confidence in interpersonal communication among the students included in this study. However, given the cross-sectional design, the findings should be interpreted as an association rather than evidence of a causal relationship.
