Brief summary

Purpose of the study is the validity and reliability of the Turkish version of the Sydney Swallow Questionnaire (SSQ-T), so that it would be used as an assessment tool for Turkish dysphagia patients. Despite being translated and validated in many languages, there is no validated Turkish version of SSQ to measure the severity of oropharyngeal dysphagia.

Detailed description

The swallow function is a multidirectional process that depends on complex neuro-muscular network. The function can be evaluated using instrumental, such as fibreoptic endoscopic evaluation of swallowing (FEES), videofluoroscopy, or well structured questionnaires. There are many questionnaire and scales for assessment of swallow but very few have been validated. The study will assess the construct validity and reliability of the Turkish version of Self-report Symptom Inventory as known as Sydney Swallow Questionnaire. The investigators developed the Turkish version of this questionnaire (SSQ-T), according to the cross-cultural adaptation guidelines. Two translators translated the SSQ into Turkish and a native English language speaker reverse-translated it into English. The back translation was sent to the original author for proofreading. The SSQ questionnaire consisted of 17 basic questions related with dysphagia symptoms.

Design outcomes

Primary

MeasureTime frameDescription
Turkish Version of Sydney Swallow QuestionnaireBaselineTurkish version of the questionnaire consists of 17 questions about dysphagia and swallowing functions and dysphagia consequences during patients at least six months and healty subjects. The minimum score is 0 and maximum score is 1700. The lower scores mean a normal swallowing function, higher scores mean worst oropharyngeal swallowing functions.

Secondary

MeasureTime frameDescription
Eating Assessment ToolBaselineThe Turkish validated questionnaire consists of 10 questions that scores are from 0 to 40. Low score is better, higher score is worse.
Penetration and aspiration scaleBaselineThe scale consists of 8 levels for assessment of penetration and aspiration. The scores are from 0 to 8. Low score is better, higher score is worse.
YALE scale of pharyngeal residueBaselineThe scale consists of 5 assessment units for pharyngeal residue. The scores are from 1 to 5. Low score is better, higher score is worse.
