Question

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

A BCBA reviews four sessions of stable baseline data followed by two overlapping intervention points for leaving the instructional area. The next decision depends on measurement validity and reliability. What should the BCBA do? The case file includes 5 recent sessions, 4 implementers, and 1 setting.

A
Check measurement quality, observer agreement, and procedural integrity before making a major decision in relation to learner's leaving the instructional area

Correct answer

B
Change the intervention immediately based on the concern alone
C
Continue unchanged and ignore the new contextual information
D
Add a punishment procedure before clarifying function, risk, or feasibility

Explanation

Answer A

The clue is the combination of four sessions of stable baseline data followed by two overlapping intervention points, leaving the instructional area, and the required task: Measurement validity and reliability. The case file includes 5 recent sessions, 4 implementers, and 1 setting. Check measurement quality, observer agreement, and procedural integrity before making a major decision in relation to learner's leaving the instructional area is best because it answers that clue through measurement quality and procedural integrity 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 four sessions of stable baseline data followed by two overlapping intervention points, leaving the instructional area, and the required task: Measurement validity and reliability. The case file includes 5 recent sessions, 4 implementers, and 1 setting.

Trap
Common trap

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

If you missed it, review Internal validity and confounds

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

Why the other choices are weaker

B
Choice B

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

C
Choice C

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

D
Choice D

A punishment-first response is weaker when less intrusive, function-based, or assessment steps have not been addressed.
