ABSTRACT
ABSTRACT Purpose: to describe at which age do speech and language therapists consider the / l /, / ɾ /, / r / phonemes should be acquired; to describe the criteria used by speech and language therapists to consider a phoneme as acquired; and to investigate the diagnostic criteria used by these professionals. Methods: this is an analytical cross-sectional study in which an online questionnaire was completed by 151 speech and language therapists from the Metropolitan region of Chile. The questionnaire included questions regarding the aims of this study. Results: around a 30% of respondents considered the /l/ phoneme to be acquired between 3,6-4,6 years, a 72% agreed on the /ɾ/ phoneme to be acquired from 4,0 to 4,11 and a 40% declared the acquisition of the /r/ phoneme between 5,6-5,11. When determining a phoneme as acquired, a 46.3% of interviewees referred to do it only when it was produced always and a 30% declared to consider as such when produced more than 50% of the times. When exposed to a real case, respondents provided three different diagnostic options. Conclusion: results showed a wide age range in which speech and language therapists consider the lateral and rhotic phonemes to be acquired, showing no consensus. There are diverse criteria to determine when each phoneme is acquired. Similarly, different opinions were evidenced regarding when a disorder would be defined as phonologic or articulatory.
RESUMEN Objetivo: describir la edad en que consideran que deben estar adquiridos los fonemas / l /, / ɾ /, / r /; describir el criterio que utilizan fonoaudiólogos para considerar un fonema adquirido; e indagar sobre los criterios diagnósticos que utilizan estos profesionales. Métodos: se realizó un estudio transversal analítico mediante un cuestionario validado, presentado de manera online, a 151 fonoaudiólogos de la Región Metropolitana de Chile, con preguntas referidas a los objetivos presentados. Resultados: aproximadamente un 30% de los encuestados consideró que el fonema /l/ se adquiría entre 3,6-4,6 años, /ɾ/ entre 4,0-4,11 un 72% y /r/ entre 5,6-5,11 un 40%. El 46,3% considera que un fonema está adquirido cuando se dice siempre y un 30% cuando lo dice más del 50% de las veces. Ante el relato de un caso, los encuestados eligieron tres opciones diagnósticas diferentes Conclusión: se observa que existe una amplia variedad de rango etario en la que los fonoaudiólogos creen que deben adquirirse los fonemas lateral y róticos no encontrándose un consenso. Existe una alta variedad de criterios respecto a cuándo considerar un fonema como adquirido. También existen distintas concepciones sobre cuándo un trastorno se considerará articulatorio o fonológico.
