BackgroundThe “General Oral Health Assessment Index” (GOHAI) was widely used in clinical or epidemiological studies worldwide, as it was available for use in different languages. Therefore, the aim of this study was to evaluate the psychometric characteristics of the GOHAI in a representative sample of patients with schizophrenia.MethodsA total of 90 schizophrenic patients (in-patients and out-patients) were recruited from the participants of the “buccodor study” (NCT02167724) between March and September 2015. They were selected using a random stratified sampling method according to their age, sex, or residential area (urban/rural area). GOHAI validity (construct, predictive, concurrent and known group validity) and internal consistency (reliability) were tested. Test-retest reliability was evaluated in 32 subjects.ResultsThe mean age was 47.34 (SD = 12.17). Internal consistency indicated excellent agreement, with a Cronbach’s value of 0.82 and average inter-item correlation of 0.65. Intraclass correlation coefficients for test-retest reliability with 95% confidence intervals were not significantly different (p > 0.05). Construct validity was supported by three factor that accounted for 60.94% of the variance observed. 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. For known group validity, they was no significant difference of the mean GOHAI score between out or in-patients (p > 0.05).ConclusionAcceptable psychometric characteristics of the GOHAI could help caregivers to develop ways to improve the Oral Health related Quality Of Life of schizophrenic patients.Trial registrationClinical Trials Gov NCT02167724.

This research project was funded by the Agence Régionale de Santé de Bourgogne (ARS). Oral health in schizophrenia patients: a French multicenter cross-sectional studyObjective: The aim of this study was to assess the oral health status of a sample of patients with schizophrenia (PWS) in Côte d'Or region (France) and to determine the factors associated with dental status. Material and Methods:A multicenter cross-sectional descriptive study was performed. PWS were selected using a random stratified method. Dental status was investigated using the Decayed, Missing, or Filled Teeth (DMFT) index, based on 32 teeth. The Simplified Oral Hygiene Index (OHI-S), the Xerostomia Index (XI) and the Global Oral Health Assessment Index (GOHAI) for Oral Health related Quality of Life (OHrQoL) were recorded.Results: Among the 302 persons identified, 109 were included (acceptance rate was 49.1%). Of these, 61.5% were men. The mean age was 46.8 years ±12.0 years. The majority (78%) had completed a secondary education (SE). The mean duration of mental illness (DMI) was 17.9±9.4 years, and 55.5% were taking drugs.The mean DMFT was 16.6±8.1. There was a significant relationship between age, SE, oral health variables, medical conditions and OHrQoL.Conclusions: PWS describe a poor OHrQoL. The dental and hygiene index scores are poor. We observed a lack of brushing and of dental visit for these persons and a gap in oral health between PWS and general population.La santé bucco-dentaire des patients schizophrènes: une étude française transversale multicentrique Objectif : Le but de cette étude était d'évaluer l'état de santé bucco-dentaire d'un échantillon de patients atteints de schizophrénie (PS) en Côte d'Or (France) et de préciser les facteurs associés à la santé bucco-dentaire.Matériel et méthodes : Une étude descriptive transversale multicentrique a été réalisée.

In a postal study we used the Nottingham Health Profile questionnaire to assess the quality of life of elderly survivors of open-heart surgery. From January 1984 to October 1993, 146 patients over 75 years of age underwent open-heart surgery in the Department of Cardiovascular Surgery at Beasançon (France). Eleven patients (7. 5%) died in the immediate post-operative course. Patients' mean follow-up was 3.4 +/- 2.4 years. Fourteen patients died during follow-up. One hundred and four completed Nottingham Health Profile questionnaires were returned. Five per cent of the patients lived in an old people's home. Six per cent of the patients were unable to walk at all. One patient out of five felt isolated. Fifteen per cent of the patients were in constant pain. Half of the patients took sleeping pills. Conversely, 87% of the patients felt an improvement after surgery. Sixty-two per cent continued to drive. Ninety-seven patients (92%) did at least one of the following three activities: watched television, listened to the radio, read books or magazines. Fifty-eight patients (56%) walked on a regular basis. The different types of pathology, of surgical procedures and whether or not a pacemaker was implanted during the post-operative course were not reflected in the quality of life (QOL) scores. After cardiac surgery, most of the patients were physically autonomous and related to their exterior world.

The PERSEPP scale has been validated and could be used in clinical trials and in daily practice. Additional studies will then complete the validation process.
