Penelitian ini dirancang untuk mengetahui hubungan antara keberfungsian keluarga dan personality traits pada mahasiswa baru di Universitas Indonesia. Keberfungsian keluarga diukur menggunakan instrumen Family Adaptation and Cohesion Evaluation Scale (FACES II) dan Family Communication Scale (FCS), sedangkan personality traits diukur menggunakan instrumen The Mini International Personality Item Pool (The Mini- IPIP). Terdapat 667 partisipan penelitian yang merupakan mahasiswa baru Universitas Indonesia yang tersebar di 14 fakultas. Hasil penelitian menunjukkan korelasi yang positif dan signifikan antara keberfungsian keluarga dan extraversion (r = 0,170, p<0,01), agreeableness (r = 0,146, p<0,01), conscientiousness (r = 0,259, p<0,01), openness to experience (r = 0,105, p<0,01), serta terdapat korelasi yang negatif dan signifikan antara keberfungsian keluarga dan neuroticism. (r = -0,126, p<0,01). Lebih lanjut, diketahui dari ketiga dimensi keberfungsian keluarga, dimensi komunikasi memiliki korelasi paling tinggi dengan extraversion dan conscientiousness, dimensi kohesivitas memiliki korelasi paling tinggi dengan agreeableness, dan dimensi fleksibilitas memiliki korelasi paling tinggi dengan neuroticism dan openness to experience.
