Galang Satrio Adaptability Test (GSAT) merupakan instrumen pengukuran adaptabilitas yang menggunakan Computerized Adaptive Test (CAT). Seiring dalam perkembangannya, dibutuhkan pengujian validitas konstrak pada GSAT. Penelitian ini bertujuan menguji validitas konstrak menggunakan uji validitas konvergen dan diskriminan pada skor GSAT. Sebanyak 202 mahasiswa berpartisipasi secara daring untuk menyelesaikan seluruh tes. Koefisien validitas diperoleh dari skor Korelasi Pearson. Hasil analisis menunjukkan bahwa validitas konvergen terpenuhi namun berada dalam kategori rendah antara skor GSAT dengan skor Skala Penyesuaian Diri dan skor Student Adaptation to College Questionnaire (SACQ). Konvergensi yang rendah disebabkan adanya perbedaan karakteristik item, model pengukuran, dasar teoritis, dan kondisi pengambilan data penelitian. Namun terdapat koefisien validitas diskriminan yang tinggi karena tidak ditemukan korelasi antara skor GSAT dengan skor Skala Agreeableness.

Galang Satrio Adaptability Test (GSAT) is an adaptability measurement instrument that uses Computerized Adaptive Test (CAT). Along with its development, it requires testing the construct validity of GSAT. This study aims to test construct validity using convergent and discriminant validity tests on the GSAT score. A total of 202 students participated online to complete all tests. The validity coefficient was obtained from the Pearson Correlation score. The results of the analysis showed convergent validity but were in the low category between the GSAT score and the Self-Adjustment Scale score and the Student Adaptation to College Questionnaire (SACQ) score. Low convergence is caused by differences in item characteristics, measurement models, theoretical basis, and research data retrieval conditions. However, there is a high coefficient of discriminant validity because there is no correlation between the GSAT score and the Agreeableness Scale score.
