Validity and Reliability of the Turkish Version of the Sydney Swallow Questionnaire

Validity and Reliability of the Turkish Version of the Sydney Swallow Questionnaire (SSQ-T)

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.

Study Overview

• Status: Completed
• Conditions: Swallowing Disorder; Validation; Dysphagia, Oropharyngeal
• Intervention / Treatment: Other: Turkish Version of Sydney Swallow Questionnaire

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.

Healthy adults; The second group consists of 85 healty participants will given the SSQ-T consists of 17 questions, eating assessment tool-10.	Other: Turkish Version of Sydney Swallow Questionnaire; The Turkish Version of Sydney Swallow Questionnaire consists of 17 questions related with dysphagia.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Turkish Version of Sydney Swallow Questionnaire	Turkish 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.	Baseline

The minimum score is 0 and maximum score is 1700. The lower scores mean is a normal swallowing function, higher scores mean is worst oropharyngeal swallowing functions.	2 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Eating Assessment Tool	The Turkish validated questionnaire consists of 10 questions that scores are from 0 to 40. Low score is better, higher score is worse.	Baseline
Penetration and aspiration scale	The 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.	Baseline
YALE scale of pharyngeal residue	The scale consists of 5 assessment units for pharyngeal residue. The scores are from 1 to 5. Low score is better, higher score is worse.	Baseline
