Psychometric properties of the Phonological Processing Test “PROFON” in children from 4- to 7-years-old

This study explored the psychometric properties of the Phonological Processing Test (Lara, Serra, Aguilar & Flórez, 2005) in a 478 children from 4- to 7-years-old sample in bogotá and Chía, from different socioeconomic levels. This test was analyzed with difficult test, discrimination test, tetrachoric relation matrix, Alfa of Cronbach coefficient and main components analysis with varimax rotation for construct validity. Results showed, in phonological awareness, a good performance (only four items did not have this performance level), correspondence between factor analysis and the division in subscales and components, and a high reliability with low level of discrimination in the phonological memory subscale. These results are discussed with the phonological processing ability component basis.
