Quality-of-life indicators for dysphagia provide invaluable information to the
treating clinician regarding the success or failure of swallowing therapy. The
purpose of this study was to develop a clinically efficient, statistically robust
patient-reported outcomes tool that measures the handicapping effect of dysphagia
on emotional, functional, and physical aspects of individual's lives. 60
statements describing the handicapping effect of dysphagia were collected from
patient reports and divided into subscales of physical, emotional, and functional
problems. The statements were presented to 77 individuals with dysphagia.
Respondents replied never, sometimes, or always to each statement and rated their
self-perceived dysphagia severity on a 7-point equal-appearing interval scale.
Cronbach's alpha was performed to assess the internal consistency validation of
the items within the questionnaire. The final questionnaire was reduced to 25
items and administered to 214 individuals with dysphagia and 74 controls.
Test-retest was performed on 63 individuals with dysphagia. Cronbach's alpha for
the initial and final versions was strong at r = 0.96 and r = 0.94, respectively.
Significant differences occurred between the dysphagia and control groups.
Test-retest reliability was strong. We present a new, easy-to-complete,
statistically robust, patient-reported outcomes measure for assessing the
handicapping effect of dysphagia.
