Parametric analysis of response interruption and redirection as treatment for stereotypy.

The team worked with three kids who had developmental delays. All kids showed lots of hand flapping and rocking.

Each child got two kinds of RIRD. One kind used one quick demand. The other used three demands in a row. The therapists switched the kinds every day to see which worked faster.

One-demand RIRD stopped the stereotypy just as well as the three-demand kind. It also took half the time and needed fewer instructions.

Two kids started to play with toys more during the short version. No one got worse.

Barszcz et al. (2021) later showed RIRD keeps working when you move to new rooms. Their kids reached the same low stereotypy levels in fresh settings even faster than the first time.

Boyle et al. (2018) used FCT plus free toys to cut door tapping. Their mix worked, but it needed extra toys and a new communication response. One-demand RIRD gives a simpler option when you just want to block the behavior.

Lancioni et al. (2009) looked at forty-one older studies and said most tricks work “sometimes.” Saini et al. (2015) now gives a clear rule: start with one demand, not three.

You can save minutes every episode by giving one quick instruction instead of three. Shorter RIRD means more time for teaching and less client fatigue. Try the single-demand version first; if it fails, you can always add more.
