FCT multiple functions may require different messages or a carefully defined message that works across specified contexts. Assessment evidence might suggest access to help in one routine and social interaction in another. Families can ask which relation was supported, whether variables were tested separately or together, how the client distinguishes options, and how partners will deliver the correct outcome without treating one broad function label as universal.
Review FCT multiple functions
Build a matrix with context, target definition, evidence strength, communication response, relevant outcome, partner action, signal, opportunity, and review rule. Keep separate denominators when contexts or outcomes differ. If an experimental condition combined variables, state that the individual contribution of each remains unknown.
Interpret the plan in context
More messages can improve precision but increase effort and partner training demands. One general help response can be efficient but may leave the desired outcome unclear. Direct client input, communication assessment, practical testing, and partner accuracy should guide the choice.
Use current clinical and research sources
The FCT review connects communication to the outcome maintaining another response. The response-selection guide considers effectiveness, effort, recognition, and persistence. The Ethics Code supports individualized assessment, client involvement, competence, risk, and evaluation.
Preserve communication and participation
The ASHA AAC portal supports continuous access to communication tools. For this decision, preserve established communication, ordinary supports, direct client input, consent, assent when applicable, and a usable way to decline, pause, or correct.
A practical example
At school, Lila uses help during difficult reading and talk during long unstructured waits. Across ten opportunities for each context, partners deliver the matched outcome after eight help messages and nine talk messages. The team reports each routine separately.
Questions families can use
Which functions are supported by which evidence? Were they tested separately? Does each message identify the desired outcome? Can partners respond accurately? What happens when the context is ambiguous?
