Abstract:
Objective:To cross-cultural adapt the English version of obturator functioning scale (OFS) to form a simplified Chinese version, to preliminarily verify its reliability and validity in clinic, and to provide an effective tool for evaluating the oral function and quality of life of patients with palatal defect and restored with obturators in China.
Methods:The English version of the OFS was taken for forward translation, synthesis, back-translation, and reviewed by expert committee to develop a pre-testing simplified Chinese version. This scale contained demographic data, basic information of diseases, eating problems dimensions (3 items), speech problems dimensions (5 items), and other problems dimensions (7 items). From December, 2016 to December, 2018, forty-two patients who were treated in the Department of Prosthodontics, Guanghua School of Stomatology, Hospital of Stomatology, Sun Yat-sen University with palatal defect and restored with obturators were evaluated with OFS. Among them, there were 26 males, and 21-84 years old, and 16 females, who were 24-80 years old.The reliability and validity of the data were examined and analyzed.
Results:The results showed that Cronbach′s α coefficients of the overall scale and the three dimensions (eating problems, speech problems, and other problems) were 0.926, 0.938, 0.930, and 0.935, respectively. The internal consistency of the questionnaire was very good. The Spearman coefficients between each single dimension and the total score were 0.677, 0.792, and 0.860, respectively, suggesting that the scale convergence was good. The content validity index of 15 items was 0.905, indicating that the content validity was very good.
Conclusions:The Chinese version of the OFS is exhibiting high reliability and validity, providing an effective evaluation tool of oral function and quality of life for Chinese patients with obturator prostheses to restore palate defects.
