Positive behavior support is a framework, not a single technique and not a restraint protocol. The idea, as agencies and training programs use it, is that challenging behavior is communication and that the useful response is to change what happens around the person and to teach a skill that works better. Punishment is not the point of the model. A policy that leads with restriction and calls itself positive behavior support is using the name without the practice.
The written product is a behavior support plan, usually attached to the individual support plan. The plan is what a direct support professional is supposed to follow on a shift: what tends to set off a problem, what to change in the routine, and what to do instead. Training is how that page becomes a habit. A plan nobody on the overnight shift has read is a binder.
PBS is not the same thing as a psychiatric medication decision, a school behavior plan, or a crisis protocol, though a person's week may include all of those. Waiver services sometimes fund a behavior professional who writes the plan and coaches staff. That professional is not the DSP, and the DSP is the person who will be there at 10 p.m.
This entry is the vocabulary. It is not instruction in how to respond to any person, and it does not describe physical intervention. States regulate restrictions and restraints in their own rules, often through a human rights review. Those rules are the ones an agency has to follow. The phrase "positive behavior support" in a brochure does not replace them.
When a story says a state funded PBS training, it means this framework, sold to the workforce as a skill. Whether the training changed a shift is a reporting question, not a definition.
