Lists of monosyllables for speech audiometry testing: construct validity

摘要

ABSTRACT Introduction Speech stimuli are used as part of basic audiological assessment for speech recognition analysis, and validated materials are required for this purpose. Purpose To perform construct validation of new lists of monosyllables for speech audiometry assessment. Methods The speech recognition percentage index was determined with two materials: two new lists of monosyllables, which were validated for content and considered to be equivalent, and the list of Pen and Mangabeira-Albernaz (1973), considered as the gold standard in the clinical routine of speech audiometry assessment in Brazil. The former were presented as recorded material and the latter, via monitored live voice, by the same speaker. Individuals living in the same city where the research was conducted and who had moderate to moderately severe hearing loss in at least one ear were selected from a database. Twenty right-handed subjects - aged between 18 and 44, with mixed or conductive and sensorineural hearing loss - participated in this research. The scores resulting from the application of these lists were correlated. Data were analyzed by ear; there was a total of 18 right ears and 18 left ears. Results There was no statistically significant difference between the right and left ears. There was a strong correlation between the new lists previously developed for this research and the list of Pen and Mangabeira-Albernaz in different hearing loss groups. When comparing the pairs of resulting scores, there was also a strong linear correlation between the new lists and the list of Pen and Mangabeira-Albernaz. Conclusion The new monosyllable lists were validated for the construct.
