Validity and Reliability of a Turkish Version of MD Anderson Dysphagia Inventory for Neurogenic Patients

Oropharyngeal dysphagia (OD) is a common finding in patients with neurogenic disorders.

Swallowing disorder can be acute or chronic in nature. For example, acute OD is observed in patients after stroke, head trauma, neurosurgical intervention, or in patients with Guillain-Barré syndrome. Chronic OD may develop in patients who do not recover after a stroke. Degenerative OD, Parkinson's disease, amyotrophic lateral sclerosis, myasthenia gravis, Huntington's disease, myotonic dystrophy type 1 and multiple sclerosis It is seen in patients with progressive neurological diseases. The prevalence of OD in neurogenic patients varies from 3% to 50% in stroke patients and up to almost 100% in patients with Huntington's disease. The OD can lead to weight loss, malnutrition, social isolation, aspiration pneumonia, and reduced health-related quality of life (QoL). Some studies have reported that dysphagia-specific QoL is weakly associated with OD severity measured using, among other things, fiberoptic endoscopic evaluation of swallowing (FEES) and videofluoroscopy of swallowing (VFS). Therefore, dysphagia-specific QoL questionnaires used alongside these instrumental assessments add value by providing insight into patients' perception of OD, which can be taken into account in the treatment plan. There are dysphagia-specific quality-of-life questionnaires that are actively used today: Swallowing Quality of Life Questionnaire (SWAL-QOL, 44 items), Swallowing Disability Index (30 items), Dysphagia Handicap Index (25 items) and M.D. Anderson Dysphagia Inventory (MDADI, 20 items). Multidisciplinary dysphagia clinics in our country mostly focus on the head and neck. It is visited by patients with OD of oncological or neurological origin.The M. D. Anderson dysphagia inventory is an easier inventory to perform since it has a smaller number of questions and contains more standard questions compared to other currently used questionnaires. Other questionnaires, such as the SWAL-QOL-TR and the Swallowing Disability Index, are longer than the MDADI and take more time to complete. The purpose of this study is M.D. Validity of the Turkish version of the Anderson Dysphagia Inventory for the Turkish population, reliability and cultural adaptation.
