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

July 30, 2021 updated by: Yavuz Atar, Prof. Dr. Cemil Tascıoglu Education and Research Hospital Organization

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

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Dysphagia patients
The first group consists of 85 dysphagia patients who have at least six months of dysphagia complaints. The participants will given the Turkish version of Sydney Swallow questionnaire (SSQ-T), consisted of 17 questions, eating assessment tool-10 and two scales evaluated with FEES. After the two weeks, 30 participants will given the SSQ-T for sampling.
Other: Turkish Version of Sydney Swallow Questionnaire
The Turkish Version of Sydney Swallow Questionnaire consists of 17 questions related with dysphagia.
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

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Turkish Version of Sydney Swallow Questionnaire
Time Frame: Baseline
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
Turkish Version of Sydney Swallow Questionnaire
Time Frame: 2 weeks
Turkish version of the questionnaire consists of 17 questions about dysphagia and swallowing functions and dysphagia consequences during patients at least six months. 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

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Eating Assessment Tool
Time Frame: Baseline
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
Time Frame: Baseline
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
Time Frame: Baseline
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

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
