Metode pengumpulan data menggunakan skala self-disclosure dan self- confidence yang telah divalidasi dan reliabel. Analisis data yang digunakan adalah regresi linear sederhana dengan hasil signifikan regresi sebesar P = 0,027 (< 0,05), yang berarti terdapat pengaruh antara self-disclosure terhadap self-confidence dengan koefisien determinasi (R²) sebesar 0,027 atau sumbangsih sebesar 2,7%. Hasil penelitian menunjukkan bahwa self- disclosure memiliki pengaruh positif dan signifikan terhadap self-confidence. Artinya, semakin tinggi tingkat self-disclosure mahasiswa, semakin tinggi pula self-confidence mereka.

The research employed a quantitative method with a sample of 180 students. The sampling technique used was convenience sampling. Data collection methods involved validated and reliable self-disclosure and self- confidence scales. Data analysis utilized simple linear regression, resulting in a significant regression value of P = 0.027 (< 0.05), indicating a significant influence of self-disclosure on self-confidence with a coefficient of determination (R²) of 0.027 or a contribution of 2.7%. The findings reveal that self-disclosure has a positive and significant impact on self-confidence. This means that the higher the self-disclosure level of students, the higher their self-confidence.
