Identifying the variables maintaining self-injurious behavior.

The team built a 16-question checklist called the Motivation Assessment Scale, or MAS. Teachers and aides circle answers about when self-injury happens. The form takes five minutes.

They gave the MAS to the students with autism or other delays. Then they ran full functional analyses to see what really reinforced the SIB. They compared the checklist guess to the real test results.

The MAS matched the full test in four out of five kids. It was best at spotting behavior done for attention. It was weakest at telling escape from sensory functions.

Two different teachers filled out the same form one week apart. Their answers agreed 85 % of the time, so the tool is reliable.

Putnam et al. (2003) later showed you can run the real functional analysis with toddlers as young as 18 months. Their work extends the MAS goal of early detection, but uses direct testing instead of a survey.

The MAS gives a quick screen, while F et al. prove the gold-standard test can be shrunk for little kids. Use the survey when time is short, then run the mini-analysis if results feel unclear.

No direct clash exists; the papers sit on the same bench. One hands you a fast ruler, the other shows how to double-check with a tape measure.

You now have a five-minute tool that predicts why self-injury happens in most kids with autism or delays. Start there when a full analysis is too costly or unsafe. If the MAS points to attention, try attention extinction first. If it is muddy, follow F et al. and run a brief experimental test. Either way you move from guess to data before writing the behavior plan.
