Overview

The SWEMWBS is a short version of the Warwick–Edinburgh Mental Wellbeing Scale (WEMWBS). The WEMWBS was developed to enable the monitoring of mental wellbeing in the general population and the evaluation of projects, programmes and policies which aim to improve mental wellbeing. The SWEMWBS uses seven of the WEMWBS’s 14 statements about thoughts and feelings, which relate more to functioning than feelings and so offer a slightly different perspective on mental wellbeing. The seven statements are positively worded with five response categories from ‘none of the time’ to ‘all of the time’. Children and young people are asked to describe their experiences over the past two weeks. Although the WEMWBS was not designed to monitor mental wellbeing at an individual level, research (in adults) suggests that the WEMWBS could detect clinically meaningful change (Collins, Gibson, Parkin, Parkinson, Shave & Dyer, 2012; Maheswaran, Weich, Powell & Stewart-Brown 2012).

Psychometric properties

 

Property Definiton SWEMWBS
Internal consistency Whether several items that propose to measure the same general construct produce similar score The SWEMWBS showed high internal consistency in 15–21 year olds in Norway (Ringdal, Bradley Eilersten, Bjørnsen, Espnes & Moksnes, 2018), secondary school students in Scotland and Northern Ireland (McKay & Andretta, 2017), the UK general population (Ng Fat, Scholes, Boniface, Mindell & Stewart-Brown, 2017) and Danish (Koushede et al., 2019), Swedish and Norwegian adult populations (Haver, Akerjordet, Caputi, Furunes & Magee, 2015).
Test-retest reliability Degree to which the same respondents have the same score after a period when a trait should not have changed

To our knowledge, the test-retest reliability of the SWEMWBS has not been reported for most populations, however, the WEMWBS test-retest reliability within 7-8 days after first completion was moderate in a UK population of 13-16 year olds (Clarke et al., 2010). The WEMWBS one-week test-retest reliability was high in a UK population of university students (Tennant et al., 2007)

Convergent validity Degree to which two measures of constructs that theoretically should be related are in fact related

The SWEMWBS showed positive correlation with related constructs in Welsh (Melendez-Torres et al., 2019), Scottish and Northern Irish (McKay & Andretta, 2017) secondary school children, 15-21 year olds in Norway (Ringdal et al., 2018), the UK general population (Ng Fat et al., 2017) and Danish (Koushede et al., 2019), Swedish and Norwegian adult populations (Haver et al., 2015).  Related constructs included measures related to life satisfaction and physical and mental health.

Construct validity Degree to which a test measures what it claims, or puports, to be measuring         

The SWEMWBS had good construct validity, measuring mental wellbeing in one dimension, in 15-21 year olds in Norway (Ringdal et aI., 2018) and in a Danish adult population (Koushede et al., 2019). The SWEMWBS has good model fit (Haver et al., 2015; Hunter, Houghton & Wood, 2015; McKay & Andretta, 2017; Ringdal et al., 2018; Koushede et al., 2019; Melendez-Torres et al., 2019).

Concurrent validity If a measure correlates well with a measure that has previously been validated

The SWEMWBS was strongly positively correlated with WHO-5 in a Danish adult population (Koushede et al., 2019).

Discriminant validity Lack of correlation with opposite concepts

The SWEMWBS was negatively correlated with opposite concepts in Welsh (Melendez-Torres et al., 2019), Scottish and Northern Irish (McKay & Andretta, 2017) secondary school children, 15-21 year olds in Norway (Ringdal et al., 2018), in the UK general population (Ng Fat et al., 2017) and in Danish (Koushede et al., 2019), Swedish and Norwegian adult populations (Haver et al., 2015). Opposite constructs included measures related to physical and mental health.


Populations

The SWEMWBS has been validated for populations of young people aged 15 -21 (McKay & Andretta, 2017; Ringdal et al., 2018) and the general population (Ng Fat et al., 2017). The SWEMWBS has also been validated for a Deaf population of British Sign Language Users aged 18+ (Rogers, Dodds, Campbell & Young, 2018) and in some clinical populations (Vaingankar et al., 2017).

Translation

The SWEMWBS has been translated and validated into a number of languages including Chinese, Danish, Finnish, Icelandic, Norwegian and Swedish. For more information, please contact the developers.

Administration

The SWEMWBS is designed to be completed by individuals either on paper or on a computer.

Scoring

The SWEMWBS is scored by first summing the scores for each of the seven items, which are scored from 1 to 5. The total raw scores are then transformed into metric scores using the SWEMWBS conversion table which can be found here:

https://warwick.ac.uk/fac/sci/med/research/platform/wemwbs/using/howto/swemwbs_raw_score_to_metric_score_conversion_table.pdf

Interpretation

Scores range from 7 to 35 and higher scores indicate higher positive mental wellbeing. The idea of wellbeing is fairly new, therefore, it is difficult to fully interpret what the scores mean for each individual. However, you can see how individual’s scores compare with national survey data (from adults) which can be found here:

Further interpretation will depend on your study design.
