Background:
The main objective of this study was to perform the adaptation and cultural translation and validation of the MD Anderson Dysphagia Inventory (MDADI) questionnaire for the Spanish language.
Methods:
A total of 69 patients were diagnosed with head and neck cancer treated with surgery; radiotherapy and chemoradiotherapy were included. MDADI was translated and a feasibility, internal consistency, test-retest reliability, and construct validity were assessed.
Results:
The mean overall score of the MDADI was 51.9 (18-85). Internal consistency for total score was 0.908. The overall score of intraclass correlation coefficient was 0.98 and kappa coefficient scores were almost perfect (test-retest reliability). All domains of MDADI were significantly correlated with physical and mental domains of the SF-12. Construct validity was also evaluated with food texture measures, and with TNM classification.
Conclusion:
The translation and validation of the Spanish version of the MDADI was performed and can be considered an important patient-reported outcomes tool for dysphagia-related quality of life.

01:31Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
