Validation of the Turkish Swallowing Disturbance Questionnaire

Study Overview
=================
Brief Summary
-----------------
Purpose of the study is the validity and reliability of the Turkish version of the Swallowing Disturbance Questionnaire (SDQ-T), so that it would be used as an assessment tool for Turkish Parkinson Disease's (PD) patients. Despite being translated and validated in many languages, there is no validated Turkish version of SDQ to measure the severity of dysphagia in PD.

Detailed Description
-----------------
Parkinson's disease (PD) patients who suffered from dysphagia have reported significantly reduced quality of life. 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 dysphagia in PD but very few have been validated. The study will assess the construct validity and reliability of the Turkish version of Swallowing Disturbance Questionnaire. The investigators developed the Turkish version of this questionnaire (SDQ-T), according to the cross-cultural adaptation guidelines. Two translators translated the SDQ 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 SDQ questionnaire consisted of 15 basic questions related with dysphagia symptoms in PD patients.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Study group<br>The group consists of Parkinson's disease patients with dysphagia complaints. The participants will be given the Turkish version of the Swallow Disturbance Questionnaire (SDQ-T), which consisted of 15 questions and two scales evaluated with the fiberoptic endoscopic evaluation of swallowing. After two weeks, all participants will be given the SDQ-T for sampling. | Other: Turkish Version of Swallowing Disturbance Questionnaire<br>* The Turkish Version of Swallowing Disturbance Questionnaire consists of 15 questions related with dysphagia.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Turkish Version of Swallow Disturbance Questionnaire | Turkish version of the questionnaire consists of 15 questions about dysphagia and swallowing complaints. The minimum score is 0 and maximum score is 44,5. The lower scores mean a normal swallowing function, higher scores mean worst swallowing functions. | 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 Pharyngeal Residue Severity Rating Scale | The scale consists of 5 assessment units and two localisations for pharyngeal residue. The scores are from 1 to 5 each localisation. Low score is better, higher score is worse. | Baseline |
