title: A systematic review of self-reported swallowing assessments in progressive neurological disorders.
abstract: Dysphagia experienced as a consequence of neurodegenerative disease can have severe consequences on a patient's health and well-being. Regular assessment of swallowing function can assist to achieve adequate nutrition and hydration. Here we review subjective swallowing assessments currently available are suitable for use in people with neurodegenerative disease. Measurement properties were reviewed for each tool and coverage of the World Health Organization's International Classification of Functioning, Disability and Health (WHO ICF) was considered. Assessments were identified following a review of the published literature Instruments were reviewed on the basis of reliability and validity, as well as administrative properties, such an interpretability, acceptability, and feasibility. Tools were also evaluated according to the WHO ICF framework. In total, 19 studies were identified for full-text review from 13,315 abstracts. Nine self-reported dysphagia assessment tools suitable for use in progressive neurological disorders were identified. The Swallowing Quality of Life Questionnaire (SWAL-QOL) yields the strongest combination of reliability (including internal consistency and test-retest reliability) and convergent validity while simultaneously covering all WHO ICF domains. Lengthy administration time was identified as a limitation of the SWAL-QOL. The review highlights a relative lack of well-validated self-report questionnaires in dysphagia for people with progressive neurological disease. Additional validation and evaluation of the clinical utility of the tools currently available is required to further promote an informed selection of available assessments.
