ABA Fundamentals

A translational comparison of contingency‐based progressive delay procedures and their effects on contextually appropriate behavior

Iannaccone et al. (2021) · Journal of Applied Behavior Analysis 2021
★ The Verdict

Make clients DO something appropriate during delay thinning, not just wait quietly.

✓ Read this if BCBAs thinning reinforcement schedules with any population.
✗ Skip if Clinicians using dense reinforcement with no plans to thin.

01Research in Context

01

What this study did

The team worked with neurotypical adults in a lab setting. They tested two ways to stretch the time before reinforcement.

One group had to do a specific task to earn points. The other group only had to avoid problem behavior. Both groups faced longer and longer waits.

02

What they found

People who had to DO something kept doing the right thing more often. Their appropriate behavior stayed high even when waits got long.

Both groups kept problem behavior low. But only the 'do something' group kept looking good while they waited.

03

How this fits with other research

Drifke et al. (2020) saw the same pattern in kids with disabilities during FCT. They also found DRA beat DRO when stretching delays.

Capriotti et al. (2017) looks like a contradiction. They said progressive DRO worked fine for tics. But they only tested DRO types, not DRA versus DRO.

Iannaccone et al. (2023) from the same lab shows what to do when you can't use extinction. Boost reinforcer quality to help the good response win.

04

Why it matters

When you thin reinforcement schedules, always require an appropriate response. Don't just tell clients to 'sit tight' or 'don't do that.' Give them something useful to do instead. This keeps their good behavior strong while they learn to wait longer for reinforcement.

03Original abstract

Schedule thinning is an essential step in treating problem behavior, yet little research has been conducted to determine the method associated with sustained treatment effects. A frequently used method for thinning reinforcement is contingency-based progressive delay, which requires the individual to meet some criteria before the reinforcers are returned. The response requirement could be dependent on (a) contextually appropriate behavior (differential reinforcement of alternative behavior-based thinning) or (b) absence of problem behavior (differential reinforcement of other behavior-based thinning). A translational arrangement with college students was implemented to determine the effects of these 2 response requirements. Tolerance was observed regardless of thinning method and was indicated by low rates of responding to the analogue problem behavior; however, more contextually appropriate behavior occurred during differential reinforcement of alternative behavior-based thinning. These results support the use of response requirements for behaviors that are expected of the individual when reinforcement is not immediately forthcoming.
