Abstract
The Warwick-Edinburgh Mental Well-Being Scale (WEMWBS) has been validated in general population samples in many countries. Interest in using this measure in clinical populations is growing, particularly for tertiary prevention and mental health promotion. This paper reports validation of the French WEMWBS in healthy and chronic remitted schizophrenia populations. The French WEMWBS was administered to 319 workers, 75 students and 121 patients. For non-patients, self-reported Trait- and State-Anxiety, Mindfulness, Positive and Negative Affect and the General Health Questionnaire were completed. For patients, the Positive and Negative Syndrome Scale, Clinical Global Impression Severity Scale, Birchwood Insight Scale, Social Adjustment Scale, and Global Assessment of Functioning scale were completed. Test-retest reliability and responsiveness to intervention was assessed at 6 months. Whatever the sample, response frequencies showed normal distributions, and internal consistency was good (Cronbach's α). Scree plots of eigenvalues suggested a single factor in the samples. The one-dimensional solution yielded suboptimal fit indices. Construct validity was confirmed. Significant improvement in scores was observed before and after intervention. Test-retest variation was non-significant. Impairment of insight and cognition in the assessed patients implies that attention must be paid before applying WEMWBS to all patients. Nevertheless, WEMWBS proved valid and reliable in a further European population, suggesting transcultural validity for both monitoring and evaluation of interventions in healthy as well as chronic remitted schizophrenia populations.
