Distinguish Planned Adaptation From Treatment Drift

To distinguish planned adaptation from treatment drift, identify what changed, who authorized it, why, when, for whom, and how long it should last. Classify clinician-approved individualization, temporary safety or access responses, implementation errors, environmental workarounds, and unreviewed drift separately. Review client feedback, integrity, outcomes, and adverse effects before deciding whether to retain, revise, train, or stop the variation.

Record the exact change

Compare the observed step with the active written version. Describe the difference without guessing motive or labeling the implementer.

Capture the cue, expected component, observed action, timing, setting, client response, and evidence source. Verify which version was available to the implementer, including printed or cached copies. Preserve disputed facts and visibility limits. A neutral description supports safety review, coaching, system repair, or plan revision without treating an unclassified difference as misconduct.

Identify authority and rationale

Document the role that approved the change, the clinical, safety, access, or feasibility reason, the start date, scope, and review trigger.

Confirm that the approver held authority for the affected decision and that recipients received the change. Separate a qualified prospective adaptation from urgent interim direction, an implementer workaround, and a later explanation. Include the client's response and interdisciplinary input when relevant. Approval should be traceable to exact content and conditions rather than a general verbal impression.

Use more than a binary fidelity score

Track planned adaptation, temporary response, implementation error, system workaround, unreviewed drift, and unresolved classification. Each state needs its own action.

Define the categories before review and state what evidence moves an item between them. A missing material may create a system workaround, while ambiguous procedure language can leave classification unresolved. Report every state separately from strict-version fidelity. Route immediate client protection promptly, but keep employment, certification, clinical, quality, and operational decisions within their authorized processes.

Evaluate the changed version

Review Esme's experience, access, outcome, risk, burden, and implementation under the adaptation. Approval does not prove benefit or continued fit.

Set an evidence window, opportunity definition, follow-up owner, and stopping conditions when the adaptation begins. Compare the intended mechanism and client-valued outcome with actual exposure, integrity, and unwanted effects. Ask the client accessibly whether the change helps. At review, continue, revise, formalize, end, or refer through qualified decision-making and preserve the transition history.

Audit how the classification affects reporting. Present strict-version integrity, approved-adaptation implementation, unresolved differences, and drift separately rather than selecting whichever denominator gives the cleanest score. Track whether temporary changes expire or become formal versions. Recurring workarounds can reveal an unworkable procedure or system barrier even when each individual event initially appears minor.

Put the adaptation and drift classification into practice

Esme's hand injury leads the qualified clinician to approve a temporary one-handed preparation sequence with a dated review. That is a planned adaptation. A staff member later omits AAC without authorization, and another changes the consequence because supplies are missing. Those events enter different classifications and repair routes.

Compare measurement options for Esme

Esme's team compares direct observation, component scoring, opportunity sampling, duration, permanent product, structured interview, system record, and direct client feedback only when each option can answer the adaptation and drift classification log's decision. Record validity, visibility, reactivity, effort, privacy, access, timeliness, and what each source cannot establish.

Pilot Esme's adaptation and drift classification log

Test the definition, form, observer instructions, technology, access, timing, missing-data states, and review workflow in representative conditions. Ask Esme and the implementer whether the process changes the routine or adds burden. Revise the measurement system before using it for coaching, treatment change, supervision, or performance decisions.

Protect access and clinical responsibility for Esme

Esme's review keeps AAC, interpreters, mobility, food, water, bathroom use, prescribed care, health support, rest, relationships, and emergency help available. Obtain required consent and assent when applicable and follow the governing response to withdrawal or distress. A qualified clinician retains responsibility for clinical interpretation and treatment decisions; a fidelity score does not transfer that responsibility.

Keep procedure versions and evidence states separate

For Esme, record the active procedure version, date, author, authorized adaptations, temporary responses, observed deviations, missing evidence, and unresolved classifications. Preserve the original record. Add a dated explanation whenever a correction or later review changes the procedure version used to judge an observation.

Ask six integrity questions for Esme

Use these questions in the adaptation and drift classification log:

Which decision, procedure version, component, cue, and eligible opportunity apply?
Which client, implementer, setting, time, and observation conditions were sampled?
Which access, safety, health, consent, assent, and communication supports were present?
Which integrity, exposure, outcome, experience, adverse-effect, and agreement series stay separate?
Which missing evidence, adaptation, drift, burden, reactivity, or concurrent change limits interpretation?
Which owner, repair, stop rule, next evidence step, and review date follow?

Keep every unresolved item visible with a state, owner, age, and next action.

A fictional integrity example for Esme

Esme is fictional and involved in a meal-preparation program modified after a temporary hand injury. Reviewers freeze 27 version, change, authority, rationale, duration, access, safety, client-feedback, outcome, and review fields and complete 19 of 27 by the checkpoint. Every missing, unobservable, inapplicable, adapted, drifted, failed, or pending field keeps its defined state.

The adaptation and drift classification log measures evidence completeness. It does not establish effectiveness, safety, acceptability, medical necessity, authorization, payment, compliance, generalization, maintenance, or causation. Report the applicable raw counts and conditions before a percentage.

Use current sources within their scope for Esme

For Esme's adaptation and drift classification log, the CASP public summary supplies high-level individualized assessment, implementation, and evaluation scope for ABA treatment of autistic people. The BACB Ethics Code addresses competence, client involvement, consent and assent when applicable, risk, documentation, supervision, and evaluation for covered behavior analysts. The BCBA Test Content Outline includes procedural fidelity as examination content; it is not a case protocol or universal threshold.

For Esme's adaptation and drift classification log, the Ferguson practitioner guide supports observable component and eligible-opportunity design. The Essig, Rotta, and Poling review supports caution about the consistency and interpretation of fidelity reporting in the literature it examined. ASHA's AAC guidance says AAC users should always have access to their communication tools or devices. None of these sources makes one sampling rate, percentage, or repair rule valid for every case.

Close Esme's review

Ask Esme and each implementer to review the adaptation and drift classification log through accessible communication. Record the selected decision, raw evidence, procedure version, direct feedback, limitations, responsible role, repair, next observation, and review date. Reopen the analysis when the goal, procedure, client preference, access, health, setting, implementer, risk, or outcome changes.
