Verification of the metric properties of E. E. Gordon’s Advanced Measures of Music Audiation among non-music major students in Croatia

The aim of the study was to investigate the metric properties of the Advanced Measures of Music Audiation test by E. E. Gordon (1989) on a sample of nonmusic major students in Croatia. The study was conducted with female students of early and preschool education at the Faculty of Education in Osijek (N = 235). The descriptive indicators of the AMMA test and the normality of the distribution of scores in the Croatian sample do not differ from the results obtained during the standardization on the American sample and the Polish sample of nonmusic major students. It was found that the reliability coefficient of the AMMA test, calculated using the split-half technique, was 0.87, and high intercorrelation values were obtained between the Total test and the Tonal (r = 0.88) and Rhythm (r = 0.87) subtests. Lower values of the difficulty level and discrimination power (< 0.20) are the weakest features of the application of the AMMA test to the Croatian sample. Considering the overall observed metric properties, it can be concluded that the AMMA test is a reliable measurement tool for the assessment of auditory musical abilities in nonmusic major students in Croatia.
