Abstract
The development of the Oral Health Impact Profile-49 (OHIP-49) and its shorter version, OHIP-14, has been criticized for not adequately considering the influence of systemic health on Periodontal health. The lack of a Periodontal status domain in OHIP scales has led to the proposal of the development of a new profile, Oral and Systemic Health Impact Profile (OSHIP-Perio). The newly developed profile has not undergone translation into other languages, cross-cultural adaptation, or validation and reliability testing. The primary objective of this study was to conduct a cross-cultural adaptation, validation, and reliability assessment of the Turkish translation of OSHIP-Perio for the first time. The data set comprises of responses from 354 individuals who participated in a face-to-face survey involving a series of fourteen inquiries related to the influence of Periodontal diseases on their general quality of life. The survey employed the OHIP-14-TR gold standard questionnaire, which has undergone prior validation and reliability testing in cross-cultural adaptation studies. Confirmatory factor analysis was employed to evaluate the construct validity. Test-retest reliability was evaluated using the Spearman-Brown and Gutmann test. Cronbach's alpha was used to assess the internal consistency. The concurrent validity was assessed using Spearman's correlation coefficient. The confirmatory factor analysis revealed that the scale is characterized by a single factor. The Spearman's correlation coefficient results were found to be 0.922 for concurrent validity. The internal consistency analysis yielded a Cronbach's alpha value of 0.944 for the scale. The Spearman-Brown and Guttmann methods yielded coefficients of 0.972 value for test-retest reliability. No floor or ceiling effects were found to be present. The Turkish version of the OSHIP-Perio questionnaire has been found to be valid and reliable. The OSHIP-Perio-TR can be used to assess the relationship between general well-being, its influence on Periodontal health, and the perception of illness in individuals with Periodontal diseases.
