About this study
Official title: Turkish Validity And Reliability Study Of The Oral Assessment Sheet (OAS)
The aim of this observational study is to evaluate the validity and reliability of the Turkish version of the Oral Assessment Sheet (OAS). The OAS is a clinical assessment tool developed to evaluate oral health conditions such as lips, tongue, mucosa, saliva, swallowing, and voice.
This study will investigate whether the Turkish version of the OAS is a valid and reliable tool for assessing oral health status in clinical practice. Participants will undergo oral assessment using the Turkish version of the OAS. Statistical analyses will be performed to determine the validity and reliability of the scale.
The results of this study are expected to provide a standardized oral assessment tool that can be used in Turkish clinical settings.
Read the detailed description
Oral health assessment plays an important role in patient care, especially in clinical settings where oral complications may occur. The Oral Assessment Sheet (OAS), originally developed by Eilers and colleagues, is a structured clinical assessment tool used to evaluate oral conditions including lips, tongue, mucous membranes, saliva, swallowing ability, and voice.
The purpose of this study is to adapt the OAS into Turkish and to evaluate its validity and reliability. The translation and cultural adaptation process will be conducted according to internationally accepted guidelines for cross-cultural adaptation of measurement instruments. After the translation process, the Turkish version of the OAS will be applied to participants.
Statistical analyses will be performed to evaluate the psychometric properties of the Turkish version of the scale, including reliability and validity analyses. The findings of this study are expected to provide a valid and reliable oral assessment tool for use in Turkish clinical and research settings.
