Mental Health and Life Satisfaction: The Relationship between the Warwick Edinburgh Mental Wellbeing Scale and Life Satisfaction

This paper sets out the methodology and analytical approach underlying the work to measure the value to society of changes in mental health as measured by the SWEMWBS scale. This will allow organisations to estimate the social value created by interventions which improve peoples’ mental health and subsequently their overall quality of life or wellbeing.

This study investigates the statistical relationship between the SWEMWBS scale and life satisfaction whilst adjusting for other factors that drive wellbeing as guided by Fujiwara & Campbell (2011). We tested a number of different functional forms to assess the form of the relationship between life satisfaction and SWEMWBS using both parametric and non-parametric approaches to converting the overall SWEMWBS score.3 SWEMWBS is used instead of the full WEMWBS scale. The main advantage of SWEMWBS is that it is shorter. SWEMWBS has undergone more rigorous tests for internal consistency than the 14-item scale. There is more emphasis in SWEMWBS on functioning compared with the 14-item scale which is more focused on feelings (Warwick Medical School, n.d.).

An additional advantage in the context of this analysis is that SWEMWBS is available in the Understanding Society (USoc) panel data set which was used in the Social Value Bank.

This means it is possible to link SWEMWBS to life satisfaction and other variables necessary for the WV(WV) method employed by Simetrica in the Social Value Bank.
