Purpose This study aims to use a sequentially implemented intervention package to reduce the occurrence of perseverative requesting and other problem behavior in a young girl with autism spectrum disorder (ASD).

Design/methodology/approach
In this single-case study, subsequent to a functional analysis and a preference assessment, an intervention package consisting of three components (i.e. a tolerance for delay to reinforcement, choice-making and visual schedule) was implemented sequentially to address perseverative requesting and other problem behavior maintained by access to preferred items/activities in a young girl with ASD.

Findings
Via the intervention package, the girl demonstrated higher self-control skills (i.e. delaying access to preferred items/activities, choosing more preferred items/activities with delayed access over less preferred ones with immediate access, completing tasks before having access to preferred items/activities) with a reduction of perseverative requesting or other problem behavior.

Originality/value
The current case study presents concrete steps that could be applied to address tangible-maintained perseverative requesting using more natural and educationally relevant signals while improving the child’s appropriate skills (e.g. delay to reinforcement, self-control and task engagement).
