Pengumpulan data dilakukan melalui kuesioner menggunakan skala Likert 1–5, kemudian dianalisis menggunakan regresi mediasi. Hasil penelitian menunjukkan bahwa: (1) kecemasan berbicara berpengaruh negatif signifikan terhadap kemampuan public speaking mahasiswa (β = -0.41; p < 0.001), (2) kecemasan berbicara berpengaruh negatif signifikan terhadap self-confidence (β = -0.52; p < 0.001), (3) self-confidence berpengaruh positif signifikan terhadap kemampuan public speaking (β = 0.38; p < 0.001), dan (4) self-confidence memediasi secara parsial pengaruh kecemasan berbicara terhadap kemampuan public speaking. Temuan ini menegaskan bahwa penguatan kepercayaan diri mahasiswa merupakan faktor penting dalam mengurangi dampak negatif kecemasan berbicara terhadap performa public speaking.
