Elaboración y validación de una prueba de bisílabos dicóticos en español

The purpose of this study is to develop and obtain the psychometric indicators for a dichotic disyllabic test (DDT) in order to assess auditory processing. This test was developed in the unit of Audiology, School of Audiology at the University of Talca. The study included 49 normal hearing subjects, 21 of whom were re-assessed to determine the reliability coefficient. The DDT showed high test-retest reliability (r = .89; P < .01) and a significant internal consistency value (Cronbach's alpha .86). At the same time, using the construct validity, it was determined that the DDT can be used to measure the ability of dichotic listening. Higher scores were obtained in four stimuli sets than in six stimuli sets. Higher values were obtained in word recognition for the right ear than in the left ear. All these findings suggest that the DDT is valid, and can be applied to obtain normal data for an adult population.
