Well-being is an indicator of students’ happiness in school. There is currently a need to identify students’ well-being in order to know the conditions of students’ mental health and their levels of contentment in school. The existing instruments of student well-being in Indonesia have numerous items, which can impact the participants’ behavior in filling out the questionnaires. Therefore, there was a need for a shorter version of the instruments. This research focused on the adaption of the Brief Adolescent Subjective Well-Being in School Scale (BASWBSS), an instrument for subjective well-being with only eight items and was previously developed by Tian, Wang, and Huebner (2015) among high school students in China. A total of 235 Indonesian students, both high school and first-year university students were the participants in this study. Reliability testing using internal consistency, while construct and criterion validity testing was implemented to test this scale's psychometric properties in the Indonesian context. The result of this study indicated that the adaptation of Brief Adolescent Subjective Well-Being in School Scale (BASWBSS) was valid and reliable for Indonesian students.

Sebanyak 235 siswa Indonesia, yang merupakan siswa sekolah menengah atas dan mahasiswa tahun pertama, menjadi partisipan dalam penelitian ini. Uji reliabilitas dilakukan menggunakan konsistensi internal, sedangkan uji validitas konstruk dan validitas kriteria digunakan untuk menguji aspek psikometri dalam konteks Indonesia. Hasil penelitian menunjukkan bahwa hasil adaptasi dari Brief Adolescent Subjective Well-Being in School Scale (BASWBSS) valid dan reliabel untuk siswa di Indonesia.
