Psychometric Properties of Questionnaires on Functional Health Status in Oropharyngeal Dysphagia: A Systematic Literature Review

Table 4

Description of studies for the development of questionnaires for the assessment of FHS in oropharyngeal dysphagia.

Questionnaire	Reference	Target population	Study design	Study population	Age in years (mean/median, SD, and range)^2
EAT-10	Belafsky et al., 2008 [24]	Orophageal and esophageal dysphagia	Cross-sectional study	Development EAT-20; (I) Multidisciplinary group of dysphagia experts (gastroenterologists, otolaryngologists, SLTs, nutritionists).; Development EAT-10; (II) Healthy subjects (𝑁=100); (III) Subjects with voice and swallowing disorders (N = 235; 127 M, 108 F); Diagnosis: reflux disease (𝑁=66; 28%), voice disorder (𝑁=51; 22%), oropharyngeal dysphagia (including stroke, progressive neurologic disease, ALS, or pseudobulbar palsy; 𝑁=50; 21%), head and neck cancer (𝑁=42; 18%), esophageal dysphagia (including esophageal motility disorders, neoplasia, webs, strictures, or rings; 𝑁=26; 11%).	(II) NR; (III) Mean = 62 (SD = 14); range = NR
SOAL	Govender et al., 2012 [25]	After total laryngectomy	Cross-sectional study	(I) Volunteer laryngectomees from all regions of the UK; mean of 5 years after surgery (𝑁=10).; (II) Experienced SLTs (𝑁=6): item generation.; (III) Focus groups of SLPs (𝑁=35): content consensus.	(I) Mean = 63; range = NR
Self-report Symptom Inventory^1	Wallace et al., 2000 [26]	Oropharyngeal dysphagia	Cross-sectional study	Development Prototype Self-report Inventory (19 items): clinical judgement by one experienced clinician (senior author) and one SLP.; Development Modified Self-report Inventory (17 items): (I) oropharyngeal dysphagic patients with neuromyogenic etiology (𝑁 = 45; 27 M, 18 F); diagnosis: CVA—brainstem (𝑁=12), CVA—other (𝑁=2), Parkinson disease (N = 12), Movement disorder—other (𝑁=4), Myopathy (𝑁=3), MG (𝑁=1), ALS (𝑁=6), brainstem lesion—other (𝑁=2), idiopathic (𝑁=3).	(I) Mean = 70 (SD = 13); range = 30–96

1The Modified Self-report Symptom Inventory (17 items) is based on the Prototype Self-report Symptom Inventory (19 items) by Wallace et al. [26]. The Sydney Swallow Questionnaire (SSQ) named by Dwivedi et al. [27] is identical to the previously published Modified Self-report Symptom Inventory by Wallace et al. [26].
