Abstract
Aims
The oropharyngeal dysphagia (OD) poses substantial health risks and affects quality of life. Patient-reported outcome measures (PROMs) are gaining prominence for their crucial role in early detection and adapting rehabilitation and management decisions. This highlights the need for culturally pertinent versions in different languages, especially when addressing conditions like OD. This study aimed to translate, culturally adapt, and assess the test-retest reliability of the Sydney Swallow Questionnaire (SSQ), a PROM designed to detect the risk of OD, for Dutch-speaking populations.
Materials and Methods
The SSQ was translated and adapted based on Beaton’s guidelines. Validity and test-retest reliability were assessed in 100 healthy participants, with a subset of 30 participants assessed over a 15-day interval. Intra-class correlation coefficient (ICC) values were calculated to determine test-retest reliability.
Results
The SSQ-Dutch was well received and well understood, with a median total score of 65.5/1700. Notably, 95% of participants scored below the established dysphagia risk cut-off, consistent with previous validations. The 15-day interval ICC for the SSQ-Dutch total scores was 0.82 (CI 95%: 0.66–0.91), indicating good reliability. While most questions had moderate-to-good reliability, five showed slightly lower ICC.
Conclusion
The SSQ-Dutch emerges as a validated and reliable tool for assessing OD risk in Dutch-speaking individuals. Future studies should evaluate its efficacy in symptomatic populations and consider cultural variations in Dutch-speaking regions.
