Validation and psychometric properties of WEMWBS

Testimonial, quotationWEMWBS has been extensively validated in adult populations and both scales are psychometrically sound. WEMWBS has also been tested with

young people (13-15yrs), minority populations (Chinese and Pakistani) and users of mental health services and their carers. All of them share the opinion that WEMWBS is easy to complete and provides a credible picture of mental wellbeing. It is now being validated in a wide range of countries and cultures.

Mental health service users and their carers have been shown to prefer WEMWBS over other mental health scales (see here). A large study in Wales has suggested that SWEWMBS is valid in children and young people aged 11 years and upwards. SWEMWBS in Secondary Schools in Wales

Both the 14-item scale and the 7-item scale WEMWBS have been shown to be sensitive to the changes that occur in mental wellbeing promotion and mental illness treatment and prevention projects. Minimally important change has been estimated for both measures.

Various studies have shown that WEMWBS is normally distributed in the general population (although in some populations there is a slight tail at the lower end and or a slight ceiling effect at the upper end) and hence can be used in parametric analyses.

Comparisons of WEMWBS with scales of mental illness show a high level of correlation (0.6-0.9) in line with the single rather than dual continuum model (see conceptual framework underpinning WEMWBS).
