Measuring mental well-being: validation of the Polish version of the Short Warwick Edinburgh Mental Wellbeing Scale (SWEMWBS)

Abstract

Aim. The purpose of the conducted research was to adapt and evaluate the psychometric properties of the Polish version of the SWEMWBS.Method. To assess the structure of the tool and its internal consistency, data were used from 557 individuals between the ages of 25 and 63 years. To assess the validity of the SWEMWBS, 277 individuals between aged 20 to 46 years took participation.Results. Validation studies conducted on the Polish version of the SWEMWBS show that the scale is a reliable and accurate tool for measuring mental well-being. The results of confirmatory factor analysis confirmed the scale’s one-factor structure. The reliability of the scale calculated using Cronbach’s alpha α = 0.84, McDonald’s omega ω = 0.83, and Gutmann’s lambda λ = 0.83 was good. The study also confirmed the validity of the scale. The SWEMWBS was moderately positively correlated with resilience and health behaviours. We observed moderate negative correlations between well-being and depressiveness.Conclusions. The study showed that the SWEMWBS is a brief tool for measuring mental well-being with good psychometric properties.
