The Flourishing Scale (FS) is a brief eight-item inventory used to measure psychological well-being. This study evaluated the psychometric properties of the FS in a sample of 766 Chinese adolescents. The paper-and-pencil method was adopted. Confirmatory factor analysis was conducted to examine the factor structure of the FS items. Expanded Satisfaction With Life Scale and Hospital Anxiety and Depression Scale were used to examine the criterion-related and incremental validities. Results showed good internal consistency reliability, one-factor structure, strong convergent validity, and incremental validity of the FS in the current sample. We can conclude that the FS is suitable for use in the Chinese adolescent context.
