Abstract

Purpose: To examine whether level of symptoms of co-morbid psychopathology exacerbated challenging behaviours in young children with autism spectrum disorders (ASD).

Method: Using the Baby and Infant Screen for Children with aUtIsm Traits (BISCUIT)–Part 2 which measures co-morbid symptoms and the BISCUIT- Part 3 which examines challenging behaviours, 362 infants and toddlers with ASD were evaluated.

Results: Findings showed that participants scoring high on symptoms of Avoidance and Tantrum/Conduct problems had greater rates of aggressive/destructive behaviours, self-injurious behaviours (SIB) and stereotypies compared to those with low scores. Participants with high levels of Inattention/Impulsivity or Eat/Sleep concerns, compared to those with low levels, demonstrated greater aggressive/destructive behaviour and stereotypies. For symptoms of Anxiety/Repetitive Behaviours, participants with high scores displayed greater levels of stereotypies.

Conclusions: Symptoms of co-morbid psychopathology are present at a very early age for children with ASD and elevated levels of these symptoms may exacerbate challenging behaviours.

Propósito: Examinar si el nivel de comorbidad psicopatológica se exacerba ante comportamientos desafiantes en niños con trastornos de espectro autista (ASD).

Método: Utilizando la escala BISCUIT-Part 2 que cuantifica los síntomas de comorbilidad y la escala BISCUIT-Part 3 que examina el comportamiento, se evaluaron 362 infantes y niños con ASD.

Resultados: Los hallazgos mostraron que los sujetos estudiados con problemas de conducta y síntomas de evitación-rabietas obtuvieron altas puntuaciones para los comportamientos de agresión y destrucción, daño auto-infringido y estereotipias, comparados con aquellos con bajas puntuaciones. Los participantes con altos niveles de inatención e impulsividad o trastornos de la alimentación y el sueño, comparados con bajos niveles en estos criterios demostraron mayores estereotipias y conductas agresivo-destructivas. Para conductas con síntomas de ansiedad-repetición los sujetos estudiados con las más altas puntuaciones mostraron mayores estereotipias.

Conclusiones: Los síntomas de comorbilidad psicopatológica se presentan a muy temprana edad en niños con ASD y niveles elevados de estos síntomas se pueden exacerbar con comportamientos desafiantes.
