Apart from objective criteria for the evaluation of oral health (CAO, CPI…), there are no scales to evaluate the oral health of patients with schizophrenia. The only scales that do exist are for the population at large, children or the elderly. Given the severely deteriorated oral health in these schizophrenic populations, it is important to have a tool to evaluate their perception of the quality of their oral health so as to better orientate prevention programmes.

The aim of this study is to validate a tool to measure the perception of oral health in patients with schizophrenia.

To do this, patients will be invited to complete a series of self-questionnaires relative to the concept of oral health.

Inclusion Criteria:

• Patients with a diagnosis of schizophrenia according to DSM V
• Hospitalized patients or outpatients who have been taking an antipsychotic treatment for more than 2 years
• Patients older than 18 years
• Patients who have provided oral informed consent to take part in the study

Exclusion Criteria:

• Patients who are psychiatrically unstable or delusional
• Subjects on chemotherapy
