Penelitian ini bertujuan untuk mengetahui hubungan antara fleksibilitas kognitif dan persepsi dukungan sosial terhadap mental well-being serta ingin mengetahui variabel mana yang berperan lebih besar terhadap mental well-being mahasiswa. Penelitian ini bersifat korelasional yang menggunakan sampel mahasiswa (N=242). Alat ukur yang digunakan pada penelitian adalah Warwick-Edinburgh Mental Well-Being Scale (WEMWBS), Cognitive Flexibility Inventory (CFI), dan The Multidimensional Scale Perceived Social Support (MSPSS). Hasil analisis multiple regression antara fleksibilitas kognitif dan persepsi dukungan sosial terhadap mental well-being menunjukkan hasil yang signifikan (𝑅² = 0,475, p < 0,001). Persepsi dukungan sosial lebih berperan terhadap mental well-being (𝛽 = 0,48, p < 0,001) dibandingkan fleksibilitas kognitif (𝛽 = 0,401, p < 0,001). Sehingga, fleksibilitas kognitif maupun persepsi dukungan sosial dapat membantu mahasiswa dalam menjaga kondisi mental well-being.

This study aims to determine the relationship between cognitive flexibility and perceptions of social support on mental well-being and to find out which variables have a greater role in students' mental well-being. This research is correlational using a student sample (N=242). The measuring instruments used in this study were the Warwick-Edinburgh Mental Well-Being Scale (WEMWBS), Cognitive Flexibility Inventory (CFI), and The Multidimensional Scale Perceived Social Support (MSPSS). The results of the multiple regression analysis between cognitive flexibility and perceptions of social support on mental well-being showed significant results ( =² = 0.475, p < 0.001). Perception of social support plays a more important role in mental well-being (𝛽 = 0.48, p < 0.001) than cognitive flexibility (𝛽 = 0.401, p < 0.001). Thus, cognitive flexibility and perceptions of social support can help students maintain mental well-being.
