Abstract

Objective: To examine the contributions of race and diagnostic category to endorsement rates of challenging behaviours in infants and toddlers with autism, PDD-NOS and atypical development without ASD, using the Baby and Infant Screen for Children with aUtIsm Traits, Part-3 (BISCUIT Part-3).

Design: Multivariate analyses of variance (MANOVAs) on each sub-scale of the BISCUIT Part-3. Follow-up univariate analyses and post-hoc tests as needed.

Methods: Scores on the BISCUIT Part-3 were compared for 453 Caucasian and 409 African-American infants and toddlers, grouped by race and diagnosis.

Results: Significant differences between races were found on five out of 10 aggressive behaviours, while no significant differences were found on self-injurious or stereotypic behaviours. Significant differences between diagnostic groups were found on all behaviours.

Conclusion: Cultural factors should be taken into account when examining challenging behaviours in infants and toddlers with ASD.

Objetivos: Determinar las contribuciones de raza y categoría diagnóstica para la clasificación de los grados de comportamientos desafiantes en niños y adolescentes con autismo, PDD-NOS y desarrollo atípico sin trastornos del espectro autista utilizando la escala Baby and InfantScreenforchildrenwithaUtIsmTraits, Part-3 (BISCUIT Part-3).

Diseño: Análisis de varianza multivariante (MANOVAS) en cada sub-escala de elBISCUIT part-3. Seguimiento con análisis univariante y pruebas post-hoc según se necesitara.

Métodos: El puntaje del BISCUIT part-3 fue comparado para 453 niños y adolescentes caucásicos y 409 niños y adolescentes afroamericanos, agrupados por raza y diagnostico.

Resultados: Se encontró diferencia significativa entre razas en 5 de 10 comportamientos agresivos, mientras que no hubo diferencias significativas con respecto a autoagresión o comportamientos estereotipados. Se encontraron diferencias significativas entre los grupos diagnósticos en todos los tipos de comportamiento.

Conclusión: Los factores culturales deberían tomarse en cuenta cuando se examinan comportamientos desafiantes en niños y adolescentes con trastornos del espectro autista.
