Abstract

Purpose: The purpose was to develop cut-off scores for a measure of developmental level (Battelle Developmental Inventory–Second Edition; BDI-2) which could be used as a screening tool to differentiate young children with possible autism spectrum disorders (ASD).

Methods: Infants and toddlers with ASD (n = 604) and atypically-developing infants and toddlers (n = 1064) were administered the BDI-2. Cut-off scores were determined based on standard deviations from the mean of the ASD group.

Results: Using 1.5 standard deviations from the mean of the ASD group, a cut-off score of 96 was determined which had a sensitivity of 0.94 and a specificity of 0.31.

Conclusions: With high sensitivity, these cut-off scores can be used to identify children who require further assessment. In addition, the measure can be used to determine treatment targets.

Propósito: El propósito fue desarrollar puntos de corte para cuatificar el nivel de desarrollo (Segunda edición del Inventario de Desarrollo de Batelle; BDI-2) que podría ser usada como herramienta diagnóstica para diferenciar a los niños con posibles trastornos de espectro autista ASD).

Método: Se aplicó el BDI-2 a bebés y niños con ASD (n = 604) así como a niños y bebés con desarrollo atípico (n = 1064). Los puntos de corte fueron determinados basados en las desviaciones estándar a partir de la media del grupo con ADS.

Resultados: Utilizando desviaciones estándar de 1.5 a partir de la media del grupo de ADS, la puntuación del punto de corte de 96 se determinó teniendo una sensibilidad de 0.94 y una especificidad de 0.31.

Conclusiones: Con gran sensibilidad, estas puntuaciones en los puntos de corte pueden ser utilizadas para identificar a niños que requerirán valoraciones posteriores. Además, la medida puede ser utilizada para determinar metas de tratamiento.
