Autism Spectrum Disorders Clinical Trial
Official title:
Understanding Gastrointestinal Conditions in Children With ASD
The purpose of this research study is to help us learn if children with Autism Spectrum
Disorder (ASD) have gastrointestinal (stomach and intestine) problems more frequently than
children without ASD do. The investigators hope to learn if children with ASD and
gastrointestinal (GI) disorders have certain Problem Behaviors (PB), such as self-injury and
aggression, more than children with ASD but no GI disorders do. The investigators want to
learn if the Gastrointestinal Symptoms Questionnaire (GIQ) can help us tell which children
with ASD also have gastrointestinal disorders.
Hypothesis 1: Children with ASD exhibit high rates of symptomatic GI dysfunction that are
not identified by current diagnostic evaluation.
Hypothesis 2: Painful or discomfort-causing gastrointestinal dysfunctions contribute to an
elevated incidence or severity of PB in an identifiable subpopulation of PB-expressing
children. The investigators anticipate that the proposed study will raise the standard of
medical care for children with ASD by improving current methods of identifying GI
dysfunction and determining whether there is a significant relationship between GI
dysfunction and PB in this population.
