Prevalence of renewal of problem behavior during context changes

Muething et al. (2020) watched what happened when clients moved to new rooms, new staff, or new towns. They counted how often problem behavior bounced back after the move.

The team looked at past case files from many clinics. They tracked each time a behavior plan changed settings and noted if the old problem behavior returned.

Renewal showed up in 42 out of every 100 context changes. That is about four times out of ten.

When renewal hit, problem behavior tripled at first. The spike faded fast, usually within a few sessions.

Haney et al. (2022) saw almost the same numbers in feeding cases: 52% renewal and 41% resurgence. The close match tells us the 42% rule holds across different topographies.

Haney et al. (2021) took the next step. After finding renewal in four of seven kids, they added a quick mitigation package—extinction plus differential reinforcement—and wiped out renewal in every case. The 2020 count sets the base rate; the 2021 paper gives you the fix.

Silva et al. (2025) later showed that fading the old context in slowly works better than giving a cue alone. Their lab data back up the clinic count: expect renewal, then fade contexts to beat it.

Four out of ten setting changes will spark renewal. Plan for it instead of being surprised. Add a brief mitigation step—keep extinction active and reinforce a new skill—when you hand a case to a new therapist, classroom, or parent. Track the first three sessions after any move; the spike usually dies out fast if you stay consistent.
