How Should an FBA Hypothesis Change After Treatment Data?

Use treatment data to update FBA hypothesis

Write the prediction before review: if the selected support addresses the hypothesized relation, which target and replacement outcomes should change, in what conditions and period? Then report eligible opportunities, integrity, prompts, target, replacement skill, client experience, side effects, setting, health or access changes, and missing data.

Interpret the evidence cautiously

A weak outcome may reflect a wrong hypothesis, a poorly fitted intervention, low implementation, an inaccessible replacement response, insufficient opportunities, or another concurrent change. Separate these possibilities before adding intensity or restriction. A positive result also needs caution when several components changed together.

Use current assessment and ethics sources

The FBA review and FA review distinguish hypotheses, descriptive patterns, experimental relations, and treatment evaluation. The Ethics Code requires assessment-based intervention, risk consideration, documentation, and continual evaluation for covered analysts. These sources support revision from evidence.

Keep communication available

The ASHA AAC portal supports continuous access to communication tools. Preserve the person's established communication, a usable stop or correction response, ordinary supports, and accessible participation throughout this specific assessment decision.

A practical example

A plan predicts that an accessible break request will reduce Mira's defined response during difficult transitions. Across twelve eligible transitions, integrity is eleven of twelve, requests increase from two to eight, and the target remains five. Mira reports the noise is painful. The clinician updates the hypothesis and routes hearing and sensory concerns rather than calling the plan successful.

Questions families can use

What was predicted? Was the plan implemented? Did target and replacement outcomes change? What did the client report? Which setting, health, or access condition changed? What rule triggers revision?
