Abstract(s)
We developed an iOS app, the iSTIM, designed to support parents of children with autism
spectrum disorders (ASD) in reducing common repetitive vocal and motor behavior (i.e.,
stereotypy). The purpose of our study was to preliminarily test the decision-making algorithms of
the iSTIM using trained university students to implement the assessments and interventions.
Specifically, we examined the effects of the iSTIM on stereotypy and functional engagement in
11 children with ASD within alternating treatment designs. Using the iSTIM reduced
engagement in stereotypy for 8 participants and increased functional engagement in for 4 of
those participants. Our results indicate that the iSTIM may decrease engagement in stereotypy,
but that some of the decision-making algorithms may benefit from modifications prior to testing
with parents.
