Mand compliance as a contingency controlling problem behavior: A systematic review

Rajaraman et al. (2021) read every paper that tested mand compliance as a driver of problem behavior.

They mapped how researchers set up the tests and what they measured. No new data were collected.

The review shows one clear pattern: when denying a request makes problem behavior spike, granting the request turns it off.

This simple stop-go pattern hides many small choices—how long to wait, what form the mand takes, who gives the reinforcer.

Siu et al. (2011) ran single cases and found that reinforcing the mand instead of the problem behavior still gave the same FA picture. Rajaraman et al. (2021) sweep that study into their larger map, showing the tactic is safe and valid.

Smith et al. (1997) first showed that an FA that denies then grants mands can guide FCT after a silent FA. The 2021 review treats this paper as the seed idea and lists every later tweak.

Torres‐Viso et al. (2018) stretched the idea to “mands for rearrangement.” Rajaraman et al. (2021) include this twist, proving the concept works beyond simple item requests.

Perez et al. (2015) warned that kids keep using old, inefficient mands even when they spark more problem behavior. The review keeps this caution alive—picking the right mand topography matters.

When your standard FA gives flat or muddy results, run a quick mand test: deny, then grant the request. If problem behavior jumps and drops with access, you have found the function. Use that information to build FCT with a fresh, easy mand and you will save hours of guesswork.
