Longitudinal measurement invariance of the flourishing scale in adolescents

The Flourishing scale is a brief instrument to measure psychological and social aspects of well-being. In the current study, longitudinal measurement invariance of the FS was assessed in a large sample of Chinese adolescents (n = 494) who were followed longitudinally. Results found that the FS has strong longitudinal invariance over a 2-month interval and across sex. Moreover, high stability coefficients across time were found for the FS. In conclusion, the study suggests that the psychometric properties for longitudinal measurement invariance of the FS are satisfactory and the FS is a reliable measure of eudaimonic well-being in adolescence.
