Abstract(s)
Objective: The purpose of our study was to replicate and extend previous research on using
multicomponent behavioural interventions designed to reduce engagement in stereotypy by
examining their effects when implemented by parents over several months. Methods: We used
an alternating treatment design to examine the effects of the parent-implemented interventions
on engagement in stereotypy and appropriate behaviour in three children with autism
and other developmental disabilities. Results: The parent-implemented multicomponent
treatments reduced vocal stereotypy in all three participants and increased engagement in
appropriate behaviour in two participants. These effects persisted up to 24 weeks following
the parent training sessions. Conclusions: Altogether, our preliminary results support (a) the
involvement of parents as behaviour change agents to reduce engagement in stereotypy and
(b) the scheduling of regular, but infrequent (i.e. weekly to monthly), follow-up meetings
to monitor the effects of behavioural interventions in outpatient and home-based service
delivery models.
