Objectives: This compares effects of explicit delay cue to reinforcement to general delay cue to reinforcement when attempting to decrease tangible-maintained challenging behaviours of children with autism spectrum disorder (ASD).
Methods: Two school-age children with ASD participated in this study. In order to evaluate the effects of a general cue versus an explicit cue on the participants' tangibly maintained challenging behaviours, a multiple baseline design across settings with an embedded alternating treatments design was used.
Results: Results suggested that both types of delay cue to reinforcement demonstrated effectiveness on decreasing tangible-maintained behaviours of the participant. For both participants, an explicit delay cue demonstrated slightly better effects on the participants' challenging behaviours then a general delay cue.
Conclusions: This study adds an evidence to support that delayed reinforcement can be used as an effective strategy to reduce both escape and tangible-maintained challenging behaviours of children with ASD across multiple settings.
