title: The occurrence of challenging behaviours in children with autism spectrum disorders and atypical development.
abstract: OBJECTIVE
  This study examines the occurrence of challenging behaviours in children with ASDs and atypical development.
  
  
  METHODS
  This study is a descriptive non-experimental design that inspects the frequencies of challenging behaviours among two diagnostic groups. This type of methodology is important since research in this area is still in the beginning stages of development.
  
  
  METHODS
  The sample consisted of 2131 children, with 633 having an ASD and 1498 having atypical development. The Baby and Infant Screen for Children with aUtIsm Traits-Part 3 (BISCUIT-Part 3) assesses problematic behaviours within this population. The frequencies of challenging behaviours were examined along with an inspection of the co-occurring items.
  
  
  RESULTS
  Greater percentages of problematic behaviours were found in the ASD group as compared to the group with atypical development.
  
  
  CONCLUSIONS
  Challenging behaviours are variables affecting the behavioural presentation of those with ASDs and may be considered into the treatment plans for these children.
