Resumen
Purpose The purpose of the study was to validate the AQoL-8D questionnaire in the adult population of patients referred
to an otolaryngology clinic.
Methods AQoL-8D was translated into Polish. 463 patients (age18–80 years) with otolaryngological conditions were
assessed with the AQoL-8D, SF-6D, and SWLS questionnaires. We investigated the item content-relevance, factor structure
by means of Confirmatory Factor Analysis, corrected item-total correlations, Cronbach’s alpha, Pearson correlation of the
AQoL-8D scores with results from SF-6D and from the SWLS questionnaires. Finally, ANOVA was used to test the AQoL-
8D ability to group the HRQoL of patients in terms of their otolaryngological management type.
Results The median score of item content-relevance was 5.0 for all AQoL-8D items. Confirmatory Factor Analysis revealed
the following fit indices: Comparative Fit Index = 0.81; Tucker–Lewis Index = 0.80; and Root Mean Square Error of Approximation
= 0.07. Cronbach’s alpha for AQoL-8D dimensions ranged from 0.48 to 0.79. Mean item-total correlations over all
dimensions, super dimensions, and the instrument overall were higher than 0.3. There was a significant Pearson correlation
between the results obtained with AQoL-8D and SF-6D (r = 0.68), and with AQoL-8D and SWLS (r = 0.43). A one-way
ANOVA showed a significant effect of management type on HRQoL as measured by AQoL-8D [F(4,458) = 6.12, p < 0.001]
Conclusion AQoL-8D provides valid and reliable measures of HRQoL in patients undergoing otolaryngological treatment.
Because it is a generic questionnaire, it is possible to make general comparisons of otolaryngology outcomes with those
from other subspecialties.
