Study of the validity and reliability of the Phonetic-Phonological Repetition Test (TREFF) as an instrument to evaluate the phonetic-phonological performance in Chilean children

Authors

Abstract

At present, a greater repertoire of valid and reliable tests is required to evaluate the phonetic-phonological performance in Chilean children. The objective of this study is to determine the validity and reliability of the Phonetic-Phonological Repetition Test (TREFF). Validation was carried out by expert judgment and reliability was determined by statistical analysis of temporal stability and intra and inter-judge agreement. For this process, the instrument was applied in a medium-high sociocultural level child population, with a phonetic-phonological development according to what was expected for their age. The analysis of the responses was carried out by three evaluating judges, who determined if the boy or girl achieved to produce the elements evaluated. In terms of validation, the instrument was modified considering the experts' suggestions. Concerning to reliability, the results obtained demonstrated temporal stability and a high degree of concordance at the intra-judge and inter-judge levels. The study allows us to conclude that the TREFF test meets the validity and reliability criteria.
