Abstract

Introduction: Mental well-being is a relevant construct, but it has not been thoroughly studied and there are very few assessment questionnaires. Objective: Adapt and validate the Spanish version of the Warwick-Edinburgh Mental Well-Being Scale. Material and Method: A process of semantic validation was performed, followed by the application to 220 adults in order to study their psychometric properties. Results: Minimal semantic changes were introduced. Factorial analysis of the main components was used, with good results (KMO= 0.897) and very good internal consistency for a factor ((proportional to)= 0.875). This questionnaire showed very good correlation with questionnaire GHQ-12 and the one on life quality WHOQOL-BREF. The correlation test-retest was positive and statistically significant (r = 0.556, p < 0.001). Conclusion: This scale showed good psychometric indicators, being a simple and easy to apply tool to assess mental well-being in adults.
