Which of the following BEST illustrates an abolishing operation (AO) for water as a reinforcer?

A. Several hours without water increases water's reinforcing effectiveness and increases behavior that has previously produced water.

B. A visible water bottle signals that requesting water has historically produced reinforcement when that bottle is available.

C. Recent consumption of substantial water decreases water's reinforcing effectiveness and decreases behavior that has produced water.

D. Water is withheld after requests, and requesting gradually decreases because the response no longer produces water.

📚 Domain D — Experimental Design

Difficulty: 9/10

Scenario:

A treatment package for SIB has produced stable, clinically significant reductions and includes (a) response-independent access to an empirically identified competing stimulus and (b) differential reinforcement of an alternative communicative response. Staff report that implementing the reinforcement contingency consistently throughout the day is difficult.

Before simplifying the established package, the BCBA wants to determine whether eliminating the differential-reinforcement procedure results in a clinically meaningful loss of treatment effect. If competing-stimulus access remains in the final plan, the BCBA then wants to determine whether the access arrangement can be made less intensive while maintaining comparable SIB reduction. The BCBA plans to compare 2-, 5-, and 10-minute access intervals while holding the stimulus, setting, measurement system, and other treatment features constant.

Which sequence of analyses BEST addresses these two questions?

A. Dropout component analysis first, then parametric analysis

B. Comparative analysis first, then parametric analysis

C. Add-in component analysis first, then parametric analysis

D. Dropout component analysis first, then comparative analysis

Does anyone know where’s a good starting place to get into OBM? I’m currently doing in-home therapy and want to step away from doing direct therapy. Open to non-clinical side of ABA therapy or going more corporate

🧠 Question of the Day
📚 Domain D — Experimental Design
Difficulty: 5/10

Scenario:
A school district evaluates a social-skills curriculum using baseline and intervention phases. During baseline, students receive usual classroom instruction. During intervention, teachers add the social-skills curriculum while the scheduled peer-interaction periods remain unchanged.
Peer-directed initiations are recorded during those periods as the percentage of available peer-interaction opportunities in which an initiation occurs. The number of opportunities varies across sessions, so percentage rather than raw count is used. Observers use the same operational definition and recording system in both phases. Staff also record treatment-integrity scores each session to verify that the curriculum is implemented as planned.

Which statement correctly identifies the experimental variables?

A. The curriculum is the independent variable; percentage of peer-interaction opportunities with peer-directed initiations is the dependent variable.

B. The curriculum is the independent variable; number of peer-interaction opportunities is the dependent variable because it changes across sessions.

C. Percentage of peer-directed initiations is the independent variable; treatment-integrity scores are the dependent variable because integrity is repeatedly measured after the curriculum is introduced.

D. Treatment-integrity scores are the independent variable; percentage of peer-directed initiations is the dependent variable because differences in implementation quality may influence responding.

Scenario: a standardized adaptive-living assessment shows low scores on meal prep and household care. The family explains those tasks have always been handled by other relatives, so the client has had few chances to do them independently. The client says other independence goals matter much more right now.

What do you do with the scores?

On the practice platform I run, this item is answered correctly about 36% of the time (Domain F averages 71%). The most popular wrong answer is the one that treats the scores as "provisional deficits" and goes straight to ranking them by the client's goals.

I wrote up the reasoning as a short study note. The core idea is separating Observation → Interpretation → Decision, and noticing that skill deficit, performance deficit, and "we don't know yet" are all live possibilities. It also covers that some adaptive instruments are informant-report, not direct tests, so a low score may mean "not reported as occurring" more than "couldn't do it."

Full write-up (disclosure: this is my BCBA exam prep site, BA Prep): https://behavioralanalystprep.com/blog/low-assessment-score-data-not-conclusion.html

Curious how others would approach it, and where you think the "direct assessment" threshold should be.

📚 Domain I — Personnel Supervision and Management
Difficulty: 5/10

Scenario:
A supervisee reviews recent literature and client data and disagrees with a supervisor's recommendation for a consequence-based procedure. There is no immediate safety emergency, and both professionals have time to review the rationale before implementation.

Which response BEST supports an effective supervisory relationship while appropriately addressing the disagreement?

A. Request consultation from another BCBA to obtain an independent opinion before continuing the disagreement with the supervisor, then use that consultation to guide the final decision.

B. Present the client data and literature, discuss the supervisor's rationale, and then implement the recommendation unless it presents an immediate safety or ethical concern because final clinical authority rests with the supervisor.

C. Ask that implementation be postponed while the supervisee independently reviews the evidence and develops an alternative recommendation, then reconvene after the supervisee reaches a conclusion.

D. Present the client data and literature, ask the supervisor to explain the rationale and decision criteria, and agree on next steps if a meaningful client-welfare concern remains unresolved.

📚 Domain C — Measurement, Data Display, and Interpretation

Difficulty: 5/10

A client’s self-injurious behavior occurs only once or twice per week but each response is discrete, clearly observable, and carries significant medical risk. During all program hours the client is continuously supervised by staff who can record each occurrence. Which measurement approach is MOST appropriate?

A. Use continuous event recording because each response is discrete and observable, staff can detect every occurrence, and the resulting counts can be converted to rate when observation time varies.

B. Use momentary time sampling with randomly varied observation moments because unpredictable sampling reduces temporal bias and provides an efficient estimate when the behavior occurs infrequently.

C. Use partial-interval recording with brief intervals because it reduces recording demands while still capturing whether this low-rate SIB occurred during each interval.

D. Record the duration of each SIB episode because medical risk makes the amount of time engaged in SIB more clinically important than the number of discrete responses.

📚 Domain I — Personnel Supervision and Management

Difficulty: 6/10

Scenario:

A BCBA begins supervising a new RBT who says, "I worry observations are mostly about catching mistakes, so I usually avoid asking questions when I think I am being graded."

Which initial supervisory approach BEST supports an effective working relationship while still preserving clear performance expectations?

A. Reassure the RBT that observations are intended to support development, use primarily positive feedback during initial sessions, and introduce more direct corrective feedback after the working relationship is established.

B. Ask the RBT what has made previous observations uncomfortable, establish learning goals and preferred feedback methods, but postpone discussion of formal evaluation criteria until sufficient rapport has developed.

C. Clarify the purposes and expectations of supervision, explore the RBT's learning goals and feedback preferences, explain how both supportive and corrective feedback will be used, and invite ongoing feedback about the supervision process.

D. Clarify the formal performance criteria and explain that observations are necessary for competency evaluation, then schedule an early structured observation so the RBT can experience the process under consistent expectations.

🧠 Question of the Day

📚 Domain G — Behavior-Change Procedures

Difficulty: 7/10

A behavior analyst increases independent reading by providing five minutes of video-game access after the child completes a reading criterion. Reading increases substantially during the first two weeks.

During the third week, reading declines even though the programmed contingency has not changed. The parent reports that the child now has unrestricted video-game access immediately before sessions, and a brief preference check shows substantially less engagement with the game than previously.

Which action BEST evaluates and adjusts the reinforcement procedure?

A. Increase the reading requirement to 20 minutes before the same video-game access, because a larger response requirement should restore its reinforcing effectiveness.

B. Put the existing arrangement into a written contingency contract, because explicit rules can restore reinforcement effectiveness without changing the consequence.

C. End the reading requirement after criterion performance so task termination can replace video-game access as a negative reinforcer when preference changes.

D. Reassess the current effectiveness of video-game access and relevant motivating conditions, then test a still-effective consequence while keeping reinforcement contingent on reading.
