[Elaboration and psychometric properties of a well-being scale at work. The Serenat study among employees in occupational medicine unit].

Background: Well-being at work is nowadays a major public health challenge. It includes, among others, absence of psychological (anxio-depressive) symptoms, perceived positive work conditions (environment and organization), happiness and good quality of life at work. Many studies have shown that social support and control at work protect mental health while high job demands and effort-reward imbalance are risk factors for anxiety and depression.
