Abstract

Objective: The diagnostic stability of Autism Spectrum Disorders (ASD) at very young ages continues to be debated, despite empirical evidence that ASDs can be reliably diagnosed in children under the age of 3 years. This topic is of the upmost importance given that early intervention increases long-term outcomes in this population.

Methods: The goal of the current study was to examine the stability of symptoms of ASD between two assessment times for 114 toddlers. The following was compared from the first to second assessment: diagnostic classification stability, correlations between scores and the impact of time between the first and second assessment.

Results: Significant correlations were found for toddlers as young as 18 months of age. In addition, even with up to a year between assessment intervals, symptoms of ASD were relatively stable prior to 3 years of age.

Conclusions: Implications of the current findings are discussed.

Objetivo: La estabilidad diagnóstica de Enfermedades del Espectro Autista (ASD) en edades muy tempranas esta todavía en debate, a pesar de haber evidencia empírica de que ASD puede ser diagnosticado de forma fiable en menores de 3 años. Este tema es de mucha importancia ya que una intervención temprana aumenta los resultados a largo plazo en esta población.

Método: El objetivo del presente estudio fue examinar la estabilidad de los síntomas en ASD entre dos periodos de tiempo para 114 niños pequeños. Se hizo una comparación entre la primera y segunda valoración: estabilidad de la clasificación diagnóstica, correlación entre resultados y el impacto de tiempo entre la primera y segunda evaluación.

Resultados: Se encontró una correlación significativa para niños pequeños de hasta 18 meses de edad. Además, aun con un intervalo de un año entre las dos evaluaciones, los síntomas de ASD fueron relativamente estables previo a los 3 años de edad.

Conclusiones: Las implicaciones de los hallazgos actuales son discutidas.
