The objective of this study was to investigate the quality of life in stroke patients using a swallowing quality of life (SWAL-QOL) questionnaire. The correlation between SWAL-QOL questionnaire outcome and videofluoroscopic dysphagia scale (VDS) scores in stroke patients was also determined. This cross-sectional study was retrospectively conducted with 75 stroke patients with dysphagia symptoms. Videofluoroscopic swallowing study (VFSS) and SWAL-QOL questionnaires were performed for all patients. These patients were divided into an oral feeding group and a tube feeding group. SWAL-QOL scores were compared between the 2 groups. The severity of dysphagia was estimated by VDS scores according to the videofluoroscopic swallowing study results. The relationships between SWAL-QOL scores and VDS scores were also investigated. The composite score was 48.82 ± 19.51 for the tube feeding group and 53.17 ± 25.42 for the oral feeding group. There were significant differences in burden and sleep subdomains of the SWAL-QOL between the 2 groups ( P = .005 and P = .012, respectively). There was a significant negative correlation between the composite score of SWAL-QOL outcome and the total VDS score ( r = −0.468, P = .012). The pharyngeal-phase score of the VDS had significant negative correlations with the SWAL-QOL subdomains of burden ( r = −0.327, P = .013), mental health ( r = −0.348, P = .008), and social functioning ( r = −0.365, P = .029). To improve the quality of life of stroke patients, dysphagia rehabilitation should focus on the pharyngeal phase of dysphagia.

“…Finally, most of the questionnaires that have been identified in this article are based on the classical test theory, although there is a wide recognition for the added value of Rasch methods in the field of rating scales development. 41,42 Limitations of this study must be considered. It is possible that we did not capture fully the exact meaning of the items in the different questionnaires.…”

“…Because it may be difficult to isolate the contribution of dysphagia in these domains, we believe that only specific symptoms in the clinical assessment should be considered in a PRO for dysphagia in OPMD. Finally, most of the questionnaires that have been identified in this article are based on the classical test theory, although there is a wide recognition for the added value of Rasch methods in the field of rating scales development …”

The requirement for a disease‐specific patient‐reported outcome measure of dysphagia in oculopharyngeal muscular dystrophy

et al. 2019

Introduction: There is no patient‐reported outcome (PRO) questionnaire specifically designed to assess oropharyngeal dysphagia in oculopharyngeal muscular dystrophy (OPMD). To select a suitable questionnaire, content validity of the existing questionnaires must be assessed. This study sought (1) to identify dysphagia‐related symptoms in OPMD and (2) to assess content validity of currently available PRO for the assessment of dysphagia severity in OPMD. Methods: A two‐step literature review was conducted of dysphagia‐related symptom identification and oropharyngeal dysphagia‐related PRO. Symptoms were validated with an expert panel by using a Delphi survey. Content validity of PRO questionnaires was documented through content analysis. Results: Ten PRO questionnaires were identified. None of the questionnaires cover the entire symptom spectrum in OPMD and thus lack content validity. Discussion: The development and validation of a new PRO questionnaire to assess dysphagia in OPMD is required to establish the importance of symptomatic relief from new treatments.

“…The DHI presents with promising psychometric properties, whereas many comparable measures (e.g. the EAT-10 and the SWAL-QoL) lack sufficient psychometric evidence and do not meet the psychometric criteria for measurement properties [26][27][28][33][34][35].…”

Using Classical Test Theory to Determine the Psychometric Properties of the Deglutition Handicap Index

et al. 2021

View full text Add to dashboard Cite

The Deglutition Handicap Index (DHI) is a self-report measure for patients at risk of oropharyngeal dysphagia on deglutition-related aspects of functional health status (FHS) and health-related quality of life (HR-QoL). The DHI consists of 30 items which are subsumed within the Symptom, Functional and Emotional subscales. The purpose of this study was to evaluate the psychometric properties of the DHI using Classic Test Theory according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) criteria. A total of 453 patients with dysphagia with different aetiologies were recruited concurrently at two academic hospitals. Dysphagia was confirmed by fiberoptic endoscopic and/or videofluoroscopic evaluation of swallowing. In addition, a healthy control group of 132 participants were recruited. Structural validity was determined using exploratory and confirmatory factor analyses and internal consistency by calculating Cronbach’s alpha coefficients. Hypothesis testing was evaluated using Mann–Whitney U-tests, linear regression analysis and correlations analysis. Diagnostic performance and receiver operating characteristic curves analysis were calculated. Factor analyses indicated that the DHI is a unidimensional measure. The DHI has good internal consistency with some indication of item redundancy, weak to moderate structural validity and strong hypothesis testing for construct validity. The DHI shows high diagnostic performance as part of criterion validity. These findings support that the DHI is an appropriate choice as a patient self-report measure to evaluate FHS and HR-QoL in dysphagia. Ongoing validation to assess the measure for possible item redundancy and to examine the dimensionality of the DHI using item response theory is recommended.
