Validation of the Swedish M. D. Anderson Dysphagia Inventory (MDADI) in patients with head and neck cancer and neurologic swallowing disturbances.

The aim of this study was to validate the Swedish version of the dysphagia-specific quality-of-life questionnaire, the M. D. Anderson Dysphagia Inventory (MDADI).

A cross-sectional validation study of the Swedish version of SWAL-QOL.

The purpose of this study was to evaluate the psychometric properties of the Swedish version of the Swallowing Quality of Life questionnaire (SWAL-QOL). The study design was cross-sectional and the study was performed in patients with subjective oropharyngeal dysphagia due to head and neck (H&N) cancer (n = 85) or neurological disease (n = 30) and in a sample of age- and gender-matched controls (mean age = 63 years, 57% males) without subjective dysphagia (n = 115). The Short-Form 36 (SF-36) and Hospital Anxiety and Depression Scale (HADS) questionnaires were used for assessment of convergent and discriminant validity.
