“…The first questionnaire was the Swallowing Quality of Life Questionnaire (SWAL-QOL), which was administered to assess patients' perceived swallowing disorder. The SWAL-QOL has been translated and validated for use with Dutch oral, oropharyngeal, and laryngeal cancer patients [25,26]. The SWAL-QOL consists of 44-items that assess the effects of swallowing difficulties on 10 QoL domains (30 items), including food selection, eating duration, eating desire, fear, burden, mental health, social functioning, communication, sleep, and fatigue.…”

“…Additionally, at the 6-year assessment point, the SWAL-QOL and the Voice Handicap Index (VHI) questionnaires were administered. The SWAL-QOL is one of the validated questionnaires for assessing patients' swallowing impairment (44-items that assess 10 QoL domains, each ranging from 0 to 100 with a higher score indicating more impairment) [49,50]. The VHI is a validated 30-item questionnaire scored on a 0-4 point scale for measuring patients' subjective suffering caused by dysphonia, specified into three subscales (physical, functional, emotional) identified with ten items each.…”

Concurrent chemoradiotherapy (CCRT) for advanced head and neck cancer (HNC) is associated with substantial early and late side effects, most notably regarding swallowing function, but also regarding voice quality and quality of life (QoL). Despite increased awareness/knowledge on acute dysphagia in HNC survivors, long-term (i.e., beyond 5 years) prospectively collected data on objective and subjective treatment-induced functional outcomes (and their impact on QoL) still are scarce. The objective of this study was the assessment of long-term CCRT-induced results on swallowing function and voice quality in advanced HNC patients. The study was conducted as a randomized controlled trial on preventive swallowing rehabilitation (2006-2008) in a tertiary comprehensive HNC center with twenty-two disease-free and evaluable HNC patients as participants. Multidimensional assessment of functional sequels was performed with videofluoroscopy, mouth opening measurements, Functional Oral Intake Scale, acoustic voice parameters, and (study specific, SWAL-QoL, and VHI) questionnaires. Outcome measures at 6 years post-treatment were compared with results at baseline and at 2 years post-treatment. At a mean follow-up of 6.1 years most initial tumor-, and treatment-related problems remained similarly low to those observed after 2 years follow-up, except increased xerostomia (68%) and increased (mild) pain (32%). Acoustic voice analysis showed less voicedness, increased fundamental frequency, and more vocal effort for the tumors located below the hyoid bone (n = 12), without recovery to baseline values. Patients' subjective vocal function (VHI score) was good. Functional swallowing and voice problems at 6 years post-treatment are minimal in this patient cohort, originating from preventive and continued post-treatment rehabilitation programs.

“…Sixteen questionnaires were obtained using these keywords. The following inventories were excluded:  Toronto Bedside Swallowing Screening Test [12]  Burk dysphagia screening test [13]  DYMUS [14]  CMDQ [15]  MASA [16]  Dysphagia screening tool in acute stroke patients [17]  Assessment of swallowing and referral to speech and language in acute stroke [18] The following questionnaires were selected:  Clinical swallowing exam [7]  Clinical screening for dysphagia [4]  Italian reflux symptom index [10]  Self-report symptom inventory [8]  EAT-10 questionnaire [5]  SWAL-QOL questionnaire [6]  Anderson dysphagia inventory [9]  Functional oral intake scale [2] All items in these questionnaires were collected in one inventory and one item from among those measuring the same function was selected in the item reduction phase. This procedure decreased the number of items to 85.Two more items were added after clinical testing by a dysphagia expert.…”

Introduction: Many patients who have had strokes suffer from dysphagia which can lead to aspiration pneumonia in 20% to 25% of cases. Early assessment of dysphagia has can reduce the risk of death and the cost of medical care. The present study developed a questionnaire to assess dysphagia in adult patients who have suffered strokes and determined the validity and reliability of the content. Methods: The phases of the study consisted of item generation, analysis of content validity and determination of reliability. To assess the content validity, the primary questionnaire was rated by five experts on swallowing disorders. Items with low scores were removed from the questionnaire. Next, 30 stroke patients were assessed using the final questionnaire and the reliability was assessed by Cronbach's alpha. Results:The average scores of the items ranged from 0.4 to 1. Only two items were omitted because of insufficient content validity. The Cronbach's alpha was 0.71 and the standard error of deviation was 4.96, signifying that the reliability was acceptable. Conclusion: This questionnaire has good content validity and reliability. Although it can be used for clinical assessment of stroke patients who suffer from dysphagia, the concurrent validity should be determined by comparison with to a gold standard such as videofluoroscopy.
