title: [The use of Quality of Life Questionnaire in patients with nasal polyposis].
abstract: OBJECTIVE
  Polyposis handicap evaluation through Spanish validation of the Rhinosinusitis Disability Index.
  
  
  METHODS
  Spanish validation of the Polyposis Disability Index (PDI). One hundred and fifty one patients referred to our Nose Unit in Fundación Hospital Alcorcón. The Spanish version of the PDI was administered after translation and retrotranslation. Internal consistency and reliability were established.
  
  
  RESULTS
  Spanish adaptation of the PDI and ists subscales (functional, emotional and physical) showed a high reliability and internal consistency (Cronbach's alfa: 0,90).
  
  
  CONCLUSIONS
  Spanish adaptation of the PDI is valid, reliable and can be used in a clinical setting to quantify the impact of polyposis on patient's quality of life.
