The Indonesian Version of the Flourishing Scale: Is it Reliable and Valid for Indonesian People?

Abstract

The Flourishing Scale (FS) was developed to measure individual psychological well-being. The FS was developed based on psychological well-being theories that include meaning and purpose in life, involvement in activities, social relationships, and feelings of competence. The psychometric properties of the FS have been studied in several countries. However, research that provides reports on reliability and validity for the Indonesian version of the FS is limited. The aim of the study was, therefore, to evaluate the psychometric properties of the Indonesian version of FS which include reliability, internal structure, and convergent validity. 1129 respondents completed the FS, Scale of Positive and Negative Experience (SPANE), and Patient Health Questionnaire 9 (PHQ-9). The Cronbach's Alpha coefficients indicate a good internal consistency of the FS. The result of the Confirmatory Factor Analysis confirmed that a single-factor structure of the FS fit to the data. The result of the Multi-Group Confirmatory Factor Analysis showed measurement invariance across two subsamples. The results of the correlation test show a significant correlation between the FS with the SPANE and PHQ-9. Taken together, the Indonesian version of the FS can be considered a reliable and valid instrument to measure psychological well-being for Indonesian people.
