Functional Case Formulation Across TCO Domains
Key Takeaways
- Integrated case items require moving across TCO6 domains without losing the functional relation.
- Start with observable behavior, context, and consequences before selecting measurement, design, or treatment.
- Domain F assessment and Domain H intervention selection should be anchored to client-informed, socially significant goals.
- Domain E ethics, cultural responsiveness, and scope of competence apply throughout the case, not only in ethics-labeled items.
Integrated Case Formulation
A strong BCBA answer keeps the case organized around behavior-environment relations. Before choosing a procedure, identify the response class, relevant antecedents, motivating operations, consequences, measurement limits, ethical constraints, and stakeholder priorities.
TCO6 domains do not appear in isolation on hard items. A single case can test Domain B concepts, Domain C measurement, Domain D design logic, Domain E ethics, Domain F assessment, Domain G procedures, Domain H intervention selection, and Domain I supervision.
Domain Map for Case Analysis
| TCO6 domain | Case question |
|---|---|
| A. Behaviorism and Philosophical Foundations | Is the answer analytic, behavioral, and conceptually systematic? |
| B. Concepts and Principles | What contingency, MO, stimulus control, or verbal process is operating? |
| C. Measurement, Data Display, and Interpretation | Are the data valid enough for the decision? |
| D. Experimental Design | Can behavior change be attributed to the intervention? |
| E. Ethical and Professional Issues | Does the action protect welfare, rights, competence, and accountability? |
| F. Behavior Assessment | What assessment data support the hypothesis and goals? |
| G. Behavior-Change Procedures | Which procedure matches the function and skill deficit? |
| H. Selecting and Implementing Interventions | Is the plan evidence based, feasible, acceptable, and monitored? |
| I. Personnel Supervision and Management | Can staff implement with integrity and receive data-based feedback? |
Case Formulation Sequence
- Define the behavior and desired alternative.
- Identify the likely function or skill deficit from assessment data.
- Select a measurement system that fits the response and setting.
- Choose a design or evaluation strategy that can show control.
- Select function-based, least intrusive, socially valid procedures.
- Plan generalization, maintenance, procedural integrity, and supervision.
- Recheck ethics, consent, cultural variables, scope, and documentation.
Exam Signal
When a vignette includes a graph, caregiver request, technician error, and behavior-change choice, do not answer from only one domain. The best option usually preserves the full chain: assessment supports measurement, measurement supports design, design supports intervention, and ethics governs every step.
A learner's aggression increases during difficult writing tasks. Interviews suggest escape, but no direct data have been collected. Which action best reflects integrated case formulation?
A case item asks which step should come first after a referral for tantrums during transitions. Which answer is most behavior analytic?
A BCBA reviews a case with strong intervention effects but low caregiver acceptance and poor staff implementation. Which TCO6 domains are most directly implicated beyond procedures?
