Menjalin hubungan romantis yang berkomitmen adalah salah satu tugas perkembangan pada masa emerging adult. Namun, relationship quality yang rendah dapat mengakibatkan hubungan romantis tidak dapat bertahan lama. Teori Erikson menyatakan bahwa pemenuhan tugas perkembangan pada emerging adulthood untuk membangun hubungan romantis dipengaruhi oleh tugas pembentukan identitas yang terjadi di tahap sebelumnya pada masa remaja. Maka dari itu, studi kuantitatif ini bertujuan untuk melihat peranan self-concept clarity terhadap relationship quality pada emerging adult yang berpacaran di DKI Jakarta. Alat ukur Self-Concept Clarity Scale dan Quality of Relationship Inventory digunakan untuk mengukur kejelasan konsep diri dan kualitas hubungan 215 emerging adult usia 18-29 tahun yang sedang berpacaran di DKI Jakarta (MAge= 23.619; SD = 2.425), yang diperoleh menggunakan purposive sampling. Hasil menunjukkan bahwa self-concept clarity berpengaruh secara signifikan (8.1%) terhadap relationship quality pada emerging adult yang berpacaran di DKI Jakarta. / Establishing committed romantic relationships is one of the developmental tasks during emerging adulthood. However, low relationship quality can lead to short-lived romantic relationships.
