This paper reports validation of the French WEMWBS in general and psychiatric populations. WEWMBS was included in the report submitted to Mental Health Research Network (2010) who addressed consensus around the measures of general mental health outcomes and was deemed to be appropriate and relevant for assessing people with psychosis and mood disorder.

Results showed that WEMWBS proved valid and reliable in a further European population, despite the limits of the study, such as its small, convenience, and non-representative samples. It highlighted the scale trans-cultural validity. It is also valid and reliable in patients with chronic remitted psychiatric disorder, such a schizophrenia. WEMWBS is sensitive to change following wellbeing promoting interventions in both psychiatric and non-patient populations.

Caution must be paid to bias any attributed to the absence of a priori determination of the required sample sizes of the conclusions, such as acceptability of the instrument or its sensitivity to change. Furthermore, impaired insight and cognition in the assessed patients also imply to pay attention must be paid before applying WEMWBS for all patients. Nevertheless, such a validated well-being measure for patients with schizophrenia may enhance the understanding of consequences of this chronic illness in cognition and emotion, and social functioning as well as being useful in specific care interventions for which there is a great need.
