Angka perceraian di Indonesia cenderung meningkat tiap tahunnya. Salah satu alasan pasangan bercerai adalah perselingkuhan. Terdapat indikasi bahwa seiring perkembangan zaman, individu memiliki sikap yang cenderung permisif terhadap perselingkuhan sehingga menjadi lebih rentan melakukan perselingkuhan. Penelitian ini bertujuan melihat pengaruh self-disclosure pada sikap terhadap perselingkuhan yang dimiliki individu dalam perkawinan. Penelitian ini juga melihat peran kepuasan perkawinan yang dimiliki individu dalam memediasi hubungan antara self-disclosure dan sikap terhadap perselingkuhan. Alat ukur yang digunakan dalam penelitian ini adalah Attitude toward Infidelity Scale (ATIS; Whatley, 2008), Marital Self-disclosure Questionnaire (MSDQ; Waring, et al., 1998), dan Couple Satisfaction index (CSI; Funk & Rogge, 2007). Teknik statistik deskriptif, korelasi, regresi sederhana dan analisis mediasi digunakan untuk menganalisis data. Penelitian ini dilakukan pada 461 partisipan yang berada dalam perkawinan (361 perempuan, 100 laki-laki). Hasil penelitian menunjukkan bahwa self-disclosure memiliki pengaruh yang signifikan pada sikap terhadap perselingkuhan. Selain itu, dapat diketahui bahwa kepuasan perkawinan berperan memediasi secara penuh hubungan antara self-disclosure dan sikap terhadap perselingkuhan.
