To define a response class for contingency assessment, identify Wade's client-relevant action and include accessible forms that share the same proposed consequence relation. Specify onset, offset, opportunities, response window, prompts, effort, latency, intensity when relevant, omissions, corrections, invalidity, and observer agreement. Keep actions with different outcomes or functional histories separate even when they look similar or occur in the same routine.

Start with functional relevance

Define the consequence relation the response class is meant to evaluate. Similar movements can belong to different classes, and different forms can share one relation.

Include accessible forms

Work with Wade to list speech, AAC, sign, gesture, writing, movement, or assistive-technology responses that partners can recognize. Preserve device access and adequate wait time.

Define the opportunity

State what makes a response possible and relevant, when the window starts and ends, and which missing-material, partner, setting, or safety conditions invalidate it.

Code support and effort

Record prompts, models, partner interpretation, response effort, latency, corrections, repeated messages, and unavailable response modes. Supported performance has its own value and label.

Test observer usability

Train reviewers on the same examples and sample agreement across each form and boundary. A high percentage cannot repair an ambiguous response class.

Use this sequence to define a response class for contingency assessment

Start with Wade's decision and proposed consequence, include accessible forms with the same relation, define opportunities and windows, code support and exclusions, preserve unresolved actions, and validate observer use.

Build Wade's response-class definition sheet

Create one versioned response-class definition sheet for the workplace-material request review. Include Wade's priority, response class, consequence class, learning history, response and nonresponse states, time windows, value, availability, effort, delay, magnitude, quality, duration, rules, prompts, access, health, integrity, agreement, raw cells, invalidity, missingness, withdrawal, direct experience, result, uncertainty, decision, owner, correction, and review trigger. Store only decision-relevant information with role-limited access.

Validate Wade's contingency evidence

Review video or approved records to confirm that speech, AAC, and gesture forms meet the same response definition and that reaches stay separately coded. Reproduce 9, 7, 4, 12, 20/32, and four invalid opportunities. Sample observer agreement across forms, omissions, and opportunity boundaries. Confirm that the response class serves Wade's chosen decision and preserves easier, more effective communication forms.

Keep Wade's dependency, function, and experience separate

Measure response-consequence dependency within eligible response and nonresponse states. Evaluate later functional effects with evidence suited to that question. Ask Wade separately about clarity, effort, comfort, usefulness, burden, and whether assessment should continue. A strong conditional difference can coexist with an unwanted or inaccessible arrangement. Positive experience can also improve while the measured dependency stays unchanged.

Work through Wade's example

Wade has 36 planned material-request opportunities. Four are invalid because the needed material is already present. Across 32 valid opportunities, he uses speech in 9, AAC in 7, gesture in 4, and no defined request in 12. The accessible request class is 20/32. A separate reach response occurs 11 times but remains outside the class because its consequence history and meaning are unresolved. Preserve every planned and valid unit, raw count, denominator, response state, nonresponse state, consequence delivery, contact, value, prompt, rule, access condition, integrity result, withdrawal, direct report, system failure, correction, and unresolved item. This fictional example demonstrates one assessment control. It offers no universal contingency, behavioral function, diagnosis, trait, treatment effect, legal conclusion, coverage decision, payment promise, or outcome guarantee.

Address Wade's main assessment risk

Counting speech alone would report 9/32 and erase eleven accessible messages. Adding every reach would report 31/32 and assume a relation the assessment has not established. Both choices distort Wade's evidence. Review response and consequence definitions, comparison states, timing, base rates, learning history, value, availability, effort, rules, prompts, access, health, context, client experience, authority, and causal scope separately. A large conditional difference cannot repair an inaccessible or ethically unsound arrangement.

Keep contingency concepts and authority clear for Wade

The ABAI Basic Principles page lists behavioral contingencies in higher-education content. The BACB Test Content Outline covers contingencies, reinforcement, schedules, rule-governed behavior, measurement, assessment, and intervention as examination content. The current BACB Ethics Code addresses competence, involvement, consent and assent when applicable, assessment, risk, data, documentation, and evaluation for covered people. These sources do not create licensure, payer approval, or an individualized plan for Wade.

Treat contingency as more than close timing for Wade

Lattal's conceptual review presents contingency as a functional relation with empirical, theoretical, and practical dimensions. Poling and Li critique vague technical use of the word. For Wade, define the response, consequence, dependency, time window, history, and claimed functional effect instead of letting the label carry missing evidence.

Use sequential measures cautiously for Wade

McComas and colleagues discuss challenges in calculating contingencies from natural-environment sequential data. Valid response and nonresponse states, comparable windows, base rates, temporal precision, and raw cells matter. A conditional difference can describe Wade's sampled events while leaving reinforcement, behavioral function, and causality unresolved.

Preserve rules, alternatives, and mixed control for Wade

Tarbox and colleagues discuss rule following and report a small teaching study. Reed and Kaplan explain relative response allocation and obtained reinforcement in matching analyses. These sources help frame rules, prompts, direct outcomes, concurrent alternatives, bias, and effort. They provide no universal protocol or source-of-control conclusion for Wade.

Preserve treatment scope, AAC, assent, and access for Wade

The CASP public summary supplies high-level ABA behavioral-health-treatment scope for autistic people, with licensed detail outside this page. ASHA's AAC portal says AAC users should always have access to their communication tools or devices. Breaux and Smith provide assent-focused guidance in an evolving evidence base. Follow governing sources and keep health care, food, water, bathroom access, communication, mobility, rest, relationships, safety, and emergency help available to Wade.

Choose Wade's next bounded action

Wade selects the gesture forms he wants recognized and asks the team to clarify whether reaching communicates a request in this workplace. Record the qualified owner, supporting evidence, effective date, current supports, health and access state, implementation check, accessible explanation, disagreement route, and reassessment trigger. Preserve the original assessment when people, systems, responses, consequences, or preferences change. A new arrangement creates a dated version rather than an error in Wade's earlier performance.

Close Wade's contingency review

Review the response-class definition sheet with Wade, the qualified behavior analyst, relevant partners, access owners, and specialists named in the manifest. Confirm that close timing stays separate from response dependency and later functional effect, raw cells and denominators are reproducible, AAC and basic access remain protected, health questions stay with qualified professionals, and conclusions remain bounded to the sampled response, consequence, time, and context. Keep this page draft and noindex until every required review is complete.
