Kegagalan seseorang dalam menyesuaikan diri, umumnya dikarenakan munculnya kesenjangan antara individu dengan kondisi lingkungannya. Hal tersebut dapat terjadi pada mahasiswa baru. Dukungan sosial dan self efficacy berperan penting dalam proses adaptasi. Peneliti mendapatkan data awal bahwa 57,14% mahasiswa di Satu Universitas Swasta di Tangerang mengatakan kesulitan karena tidak dapat mengandalkan kemampuannya. Diketahui 35,71% mengatakan orangtua tidak peduli dengan masalah yang sedang dihadapi. Tujuan penelitian ini adalah menganalisis hubungan antara self-efficacy dengan dukungan sosial pada mahasiswa tahun akademik pertama Fakultas Keperawatan di sebuah universitas swasta di Tangerang. Metode penelitian yang digunakan adalah kuantitatif dengan desain korelasi. Teknik pengambilan sampel yaitu simple random sampling, sehingga didapatkan 231 mahasiswa tahun akademik pertama. Instrumen penelitian menggunakan kuesioner General Self-efficacy (GSE) dan skala dukungan sosial. Analisis data menggunakan korelasi Spearman. Penelitian ini dilaksanakan pada bulan Januari 2025 hingga Maret 2025. Hasil analisis univariat menunjukkan mayoritas mahasiswa memiliki tingkat dukungan sosial yang tinggi (66.7%) dan self-efficacy tinggi (71.4%). Pada analisis bivariat menunjukkan adanya hubungan positif yang lemah namun signifikan antara dukungan sosial dan self-efficacy (r =0.191 p = 0.004). Kesimpulannya, pada mahasiswa baru tingkat dukungan sosial dan self-efficacy yang dimiliki memiliki hubungan namun tergolong lemah yang mengindikasikan adanya faktor lain yang berperan. Penelitian ini merekomendasikan penelitian campuran (mixed methods) untuk eksplorasi faktorfaktor lain yang berkontribusi meningkatkan dukungan sosial dan self-efficacy mahasiswa. / An individual's belief in their ability to succeed in a given sit An individual's inability to adapt is generally due to a gap between the individual and their environmental conditions.
