Validation of a Scale of Well-being at Work

Study Overview
=================
Brief Summary
-----------------
The main objective of this work is to explore the psychometric properties of scale of well-being at work called Serenat in order to validate it. Secondary objectives are to study the influence of socio-demographic characteristics of the subjects on the results of Serenat and to describe the results on subjects monitored among an adult psychiatric population.

Detailed Description
-----------------
This is a cross sectional survey. 200 subjects were selected among people having consulted an occupational doctor to validate the scale in the general population (study 1), and 50 subjects among a psychiatric population for the ancillary study (study 2). The Serenat Scale is a self-report questionnaire composed of 20 items. All items are scored on a four point Likert scale ranging from 0 (strongly disagree) to 3 (strongly agree) resulting in a range of 0 to 60. The 20 items are related to different domains. 10 items explore psychological balance at work: relaxation (item 1), sleep quality (item 2), concentration (item 3), form (item 4), sense of security (item 5), satisfaction (item 6), quality of relationships and contacts at work (item 7), voltage or aggressiveness (item 8), optimism for the future from a professional point of view (item 9), life balance (item 10). 10 items are related to working conditions and organization of work: comfort of the working environment (item 11), time constraint (item 12), sense of competence (item 13), decision latitude (item 14), interest at work and variety of tasks (item 15), recognition (item 16), professional support (item 17), communication and transfer of information (item 18), human conflict (item 19), satisfactory work schedules (item 20).
