About

Schizophrenia is a severe and persistent psychological disorder affecting 0.7 to 1% of the world's population and 600,000 people in France. Schizophrenic patients are exposed to excess mortality and a life expectancy that is 10 to 15 years lower than the general population (excluding causes of suicide) and to numerous co-morbidities, including oral diseases.

To improve this public health problem, concrete action must be undertaken and evaluated in both quantitative and qualitative terms. While there are many quantitative indicators, there are no reliable and valid tools for the perceived oral health of these individuals in the context of their real and/or imagined world.

The results of a qualitative study previously carried out by our team (QUALITY Study: NCT02730832) made it possible to develop two hypothetical questionnaires for evaluating quality of life related to oral health, the Schizophrenia Oral Health Profile (SOHP), and a questionnaire for evaluating coping strategies with regard to oral health, the Schizophrenia Coping Oral Health Profile (SCOOHP).

However, before these questionnaires can be used in clinical practice, their psychometric properties must be validated.
