When It Fits

This assessment fits when the client can access multiple items or activities and the practitioner wants minimally intrusive preference information.

What It Captures

It captures observed approach, engagement duration, engagement frequency, non-engagement, actual observation interval, and exposure differences when relevant.

Is this a forced-choice assessment?

No. Free Operant Observation records natural engagement across concurrently available options.

Can an interrupted observation be saved?

Yes. An interrupted observation is marked partial and shows the actual observed interval.

Does high engagement prove an item is a reinforcer?

No. High engagement identifies a preliminary candidate for practitioner consideration or further assessment.
