ABSTRACT
Subjective well-being (SWB) is a multidimensional construct that should be assessed using at least two separate measurements. Meanwhile, despite of many research related to SWB in Indonesia, many of them still used a single measurement of SWB. The purpose of this study is to assess the validity and reliability of the SWB measurement in high school students. This study included 238 participants ranging in age from 15–18 years. SWB measurements included the students’ life satisfaction scale (SLSS), brief multidimensional students’ life satisfaction scale (BMSLSS), positive affect negative affect scale (PANAS), and the Satisfaction with Life Scale (SWLS). The results showed that all scales had Cronbach's Alpha greater than 0.70. The results of exploratory factor analysis revealed that the model is a good fit and most of the items have adequate loading factors. As a result, the scale used in this study has adequate validity and reliability.
