The Schizophrenia Oral Health Profile questionnaire was developed to assess the oral health-related quality of life among individuals with schizophrenia based on their perceptions rather than from caregivers. A 5-point Likert scale was used to self-report on 42 items. In the present study, different analyses were conducted to determine the dimensional structure of the final scale: (1) inter-item correlation analysis and Cronbach's α coefficient, (2) Rasch model analysis, (3) exploratory factor analysis and (4) confirmatory factor analysis. The final version of the Schizophrenia Oral Health Profile questionnaire consisted of 20 items and an internal structure composed of three dimensions: (1) emotions related to oral health, (2) oral pain and discomfort and (3) self-image, others' views and the need for care. We showed that the difficulty and discrimination indices of each of the 20 selected items were acceptable according to the Rasch model, as well as their inter-item and inter-score correlations (α = 0.875). The psychometric study of the Schizophrenia Oral Health Profile questionnaire is still in progress to investigate reproducibility, sensitivity to change and external structure.
《精神分裂症口腔健康特征问卷》是基于患者的感知而不是照顾者的感知来评估精神分裂症患者口腔健康相关生活质量的。采用 5 点 Likert 量表对 42 个项目进行自我报告。在本研究中，进行了不同的分析来确定最终量表的维度结构：（1）项目间相关性分析和 Cronbach's α 系数，（2）Rasch 模型分析，（3）探索性因素分析和（4）验证性因素分析。《精神分裂症口腔健康特征问卷》的最终版本由 20 个项目组成，其内部结构由三个维度组成：（1）与口腔健康相关的情绪，（2）口腔疼痛和不适，（3）自我形象、他人的看法和护理需求。我们表明，根据 Rasch 模型，以及项目间和项目间相关性（α=0.875），每个选择的 20 个项目的难度和辨别指数都是可以接受的。《精神分裂症口腔健康特征问卷》的心理测量学研究仍在进行中，以调查其可重复性、对变化的敏感性和外部结构。
