Score Reliability and Validity of a Mexican Dialect Spanish Translation of the Flourishing Scale With Mexican Earthquake Survivors

ABSTRACT The Flourishing Scale (FS) scores have demonstrated acceptable psychometric properties in general adult populations, but no previous research has validated its use among natural disaster survivors. This study examined the reliability, validity, and measurement invariance of a Mexican dialect Spanish translation of the FS in 289 Mexican community earthquake survivors (39.4% male, 60.6% female; M age = 38.6 years) displaced for over 1 month following the 2017 magnitude 7.1 Puebla earthquake. The eight‐item FS demonstrated excellent internal consistency (Cronbach's α = .963) and a unidimensional structure (CFI = .988, TLI = .983, SRMR = .020). Convergent validity was established through significant correlations with the Multidimensional Scale of Perceived Social Support ( r = .53) and Satisfaction with Life Scale ( r = .50). Measurement invariance testing demonstrated both configural and scalar invariance across sex. Its use for assessing positive mental health outcomes in postdisaster contexts was supported.
