Metrics details. Therefore, the aim of this study was to evaluate the psychometric characteristics of the GOHAI in a representative sample of patients with schizophrenia. GOHAI validity construct, predictive, concurrent and known group validity and internal consistency reliability were tested.
Test-retest reliability was evaluated in 32 subjects. The mean age was Construct validity was supported by three factor that accounted for Predictive validity was corroborated as statistically significant differences were observed between a high GOHAI score, which was associated with self-perceived satisfaction with oral health, lower age and high frequency of toothbrushing.
Concurrent validity was corroborated as statistically significant relationships were observed between the GOHAI scores and most objective measures of dental status. Date registered 17 June, Peer Review reports. Among somatic comorbidities in schizophrenia patients, poor oral health has been reported by many authors and contributes to the overall poor health of these patients [ 4 , 5 ]. Generally, schizophrenia leads to disturbances in the progression of thought, errors in contextual analysis and errors of logic.
Often patients with schizophrenia do not recognise their health needs and delay seeking advice or treatment [ 6 ]. They take into account the multidimensional aspects of health and consider the functional and psychosocial impacts of dental diseases [ 7 ]. A variety of OHrQOl instruments have been developed.
Validated initially in the USA, this questionnaire is available in French [ 9 ]. The GOHAI assesses self-perceived oral health through 12 questions that explore the pain, discomfort, dysfunctions and the psychosocial impacts of dental diseases [ 10 ]. It can be self-administered and is quick and easy to use.
