To reassess preference when ABA choices change, treat a new selection, refusal, loss of interest, emerging activity, health change, access barrier, or direct client report as useful evidence. Check whether the option set, method, setting, recent access, and response definition also changed. Use the least burdensome adequate recheck, preserve earlier versions, and update plans without penalizing the person for changing their mind.

Predeclare meaningful triggers

Triggers can include direct change-of-mind communication, repeated refusal, lower engagement, new interests, health or medication change, setting change, access failure, satiation, staff report, or poor treatment response. Avoid reassessing on a rigid schedule when no decision needs it.

Check the method before the person

Compare option set, representation, positions, instructions, access, response window, setting, people, recent exposure, removal, and scoring versions. A changed procedure can produce changed data. Document both rather than attributing every difference to Davi.

Ask for current meaning

Invite Davi to explain what changed, add an option, remove one, limit its use, or prefer it only with certain people or settings. Preserve private or non-treatment interests. A change of mind is ordinary communication.

Choose a proportionate recheck

Use direct conversation, natural choice, a few structured opportunities, or a fuller assessment according to the decision and uncertainty. Repeating every original trial can add burden without value. Set a stop rule and maturity point.

Version the result and plan

Keep the earlier option set, method, date, context, result, decision, and use. Add a new version with the trigger and changes. Update schedules and treatment arrangements only through qualified decision and applicable consent processes.

Monitor use without freezing preference

Track whether currently offered options remain selected, accessible, and comfortable, plus whether the targeted response changes if reinforcement is claimed. Continue to offer choice. Never require Davi to earn the right to revise a preference.

Protect Davi's choice and basic access

For Davi, preserve AAC and other effective communication, privacy, ordinary supports, adequate food and water, bathroom, mobility, prescribed care, pain response, rest, supportive relationships, and emergency help. Verify health and safety before presenting options. Use applicable consent and assent processes, honor refusal and withdrawal during nonemergency participation, and never classify an access failure as low preference.

Build Davi's evidence ladder

Begin with Davi's accessible direct report and ordinary voluntary choice. Add source-labeled caregiver or staff suggestions, natural engagement, structured preference sampling, or response-consequence testing only when the decision needs stronger evidence. Keep preference, familiarity, availability, selection, engagement, reinforcer function, treatment choice, and outcome distinct. State what each layer can and cannot show.

Explain the assessment to Davi

Use Davi's preferred language and communication mode to explain the purpose, option set, method, duration, access, presentation, any removal, response definitions, privacy, risks, stop route, possible decisions, and uncertainty. Invite nomination, rejection, correction, pause, and withdrawal. Meaningful choice includes the ability to choose none, change a choice, or value an activity outside treatment.

Build Davi's preference-change review

Create one versioned preference-change review for the weekly activity-choice checks. Include purpose, client priority, option source, setting, method, definitions, access, health, consent and assent when applicable, ordinary supports, exposure, position, prompts, refusal, no response, invalidity, stops, integrity, raw data, client report, uncertainty, qualified authority, decision, safeguards, revision, and recheck trigger.

Work through Davi's example

Davi completes two comparable 10-opportunity choice checks four weeks apart. Music is selected in 8/10 opportunities first and 2/10 later; gardening changes from 3/10 to 7/10. The options can be selected together, so counts need not sum to 10. Report both dated fractions and the simultaneous-choice rule. The pattern supports changed selection under sampled conditions, not a cause or permanent preference reversal. Preserve planned and valid units, raw counts, denominators, source labels, access states, missing conditions, refusals, stops, corrections, versions, decisions, and open work. This fictional example demonstrates one assessment control. It supplies no universal rank, preferred-item label, reinforcer function, legal conclusion, treatment effect, or outcome guarantee.

Use Davi's evidence for a bounded decision

Identify the exact decision and qualified owner before expanding assessment. For Davi, document supporting and conflicting evidence, client preference, option and method limits, access, health, alternatives, burden, further evidence, selected action, implementation check, accessible explanation, disagreement route, and review trigger. Choose the least burdensome adequate path and stop collection that cannot change action.

Review Davi's data without causal shortcuts

For Davi, show raw selections or engagement and denominators, representative exposure, direct and proxy sources, access, health context, recent availability, refusals, invalid trials, position, method integrity, missingness, alternatives, and uncertainty. Relative preference supports a candidate under sampled conditions. A reinforcement claim requires a response-consequence relation and evidence suited to that claim.

Address Davi's main assessment risk

Staff may describe Davi as inconsistent and keep offering the older option because it once ranked highly. A method change could also mimic a preference change. The review checks client meaning and procedural comparability before updating the plan. Review definitions, client meaning, option source, access, health, method fit, exposure, position, removal, integrity, comparison, causal scope, and authority separately. A familiar format cannot rescue inaccessible options or justify unnecessary burden. Technical ranking never overrides Davi's current communication or basic access.

Choose Davi's next assessment action

Davi confirms the current interest in gardening, keeps music freely available, and chooses a brief recheck after the community garden schedule changes. Record qualified owners, current safeguards, method and option versions, evidence tasks, due dates, validation, client communication, uncertainty, decision, and next review. Preserve the original data when the account changes. A later result adds an auditable version instead of rewriting what Davi selected under earlier conditions.

Apply current preference-assessment sources to Davi's method

For Davi, the CASP public summary gives high-level context for ABA treatment of autistic people. The current BACB Ethics Code addresses competence, client involvement, understandable communication, consent and assent when applicable, assessment, intervention, risk, documentation, and evaluation for covered people. BACB has no separate organizational jurisdiction. The BCBA outline includes preference-assessment design and evaluation as examination content, not a client protocol or practice authority.

Use preference-method research carefully for Davi

For Davi, Lill, Shriver, and Allen synthesized 65 articles into SPADS to help trained practitioners choose context-specific stimulus-preference assessment procedures. It identifies candidate reinforcers rather than proving a consequence's functional effect. A seven-participant DeLeon and Iwata study compared paired-stimulus, multiple-stimulus-with-replacement, and MSWO formats and described its results as preliminary. A two-child Kang study found removal-related problem behavior in paired and MSWO sessions under its tested conditions. These studies guide questions and safeguards; they do not create a universal method or threshold.

Protect assent and communication access for Davi

Breaux and Smith offer assent-focused practice guidance in an evolving evidence base. ASHA states that AAC users should always have access to their communication tools or devices. For Davi, preserve an accessible way to nominate, select, reject, pause, stop, correct, and change a choice. Do not require speech, eye contact, one motor form, compliance, or loss of essential access as the price of participation.

Close Davi's preference review

Review the preference-change review with Davi, the responsible clinician, access and operational owners, and the specialists named in the manifest. Verify that options remain accessible and optional, basic access is protected, methods fit the question, refusals and invalid trials remain visible, preference and reinforcement claims stay separate, and decisions remain within authority. Keep this page draft and noindex until every required review is complete.
