Mahasiswa menggunakan media sosial untuk berteman, melepaskan tekanan, dan mempelajari berbagai hal. Namun beberapa penelitian menemukan bahwa penggunaan media sosial yang berlebihan memiliki hubungan dengan depresi, kecemasan, gaya hidup, dan prestasi akademik mahasiswa. Hal tersebut dapat mengarah pada aspek kesejahteraan subjektif mahasiswa. Maka dari itu, penelitian ini bertujuan untuk mengetahui ada tidaknya hubungan antara intensitas penggunaan media sosial dan kesejahteraan subjektif pada mahasiswa di JABODETABEK. Studi survei kuantitatif ini menggunakan Social Networking Activity Intensity Scale (SNAIS), Satisfaction with Life Scale (SWLS), dan Scale of Positive and Negative Experience (SPANE), pada 178 mahasiswa di JABODETABEK. Hasil penelitian menunjukkan bahwa terdapat hubungan antara intensitas penggunaan media sosial dan kepuasan hidup (r_s = .329, p < .001) serta afek positif (r_s = .358, p < .001) pada mahasiswa di JABODETABEK. Kemudian, ditemukan juga tidak ada hubungan antara intensitas penggunaan media sosial dan afek negatif pada mahasiswa di JABODETABEK (r_s = .085, p = n.s). / University students use social media to make friends, release pressure, and learn things.
