Question

Difficulty: medium. Skill: apply. Type: data interpretation.

A BCBA reviews caregiver notes plus one direct observation for dropping to the floor when demands are presented. The next decision depends on direct, indirect, and product measures. What should the BCBA do? The case file includes 4 recent sessions, 3 implementers, and 3 settings.

A
Rely on parent's report alone and stop collecting direct evidence
B
Change the intervention immediately based on the concern alone
C
Choose the measurement system that matches the behavior dimension and decision question in relation to child's dropping to the floor when demands are presented

Correct answer

D
Continue unchanged and ignore the new contextual information

Explanation

Answer C

The clue is the combination of caregiver notes plus one direct observation, dropping to the floor when demands are presented, and the required task: Direct, indirect, and product measures. The case file includes 4 recent sessions, 3 implementers, and 3 settings. Choose the measurement system that matches the behavior dimension and decision question in relation to child's dropping to the floor when demands are presented is best because it answers that clue through measurement system selection instead of treating the scenario as a generic behavior problem. On exam items like this, name the decision point first, then eliminate options that rely on one report, a label, a familiar protocol, or an action that skips the relevant data check.

Why this question is hard

Key scenario clue

The clue is the combination of caregiver notes plus one direct observation, dropping to the floor when demands are presented, and the required task: Direct, indirect, and product measures. The case file includes 4 recent sessions, 3 implementers, and 3 settings.

Trap
Common trap

Stakeholder input matters, but direct data, context, and integrity checks are still needed for a defensible answer.

Next
If you missed it, review Measurement system selection

Then answer a few related scenarios before moving back to broad practice.

Why the other choices are weaker

A
Choice A

Stakeholder input matters, but direct data, context, and integrity checks are still needed for a defensible answer.

B
Choice B

This is weaker because it skips the assessment, integrity, or decision rule needed before changing procedures.

D
Choice D

Ignoring relevant data or context prevents a defensible behavior-analytic decision.
