HomeBxLogDana Do'sDana Do’s: Breaking Down a BCBA®/BCaBA® Mock Exam Question About Operational Definitions Dana Do’s: Breaking Down a BCBA®/BCaBA® Mock Exam Question About Operational Definitions March 20, 2025 This week, we posted a mock question on social media and some of you requested clarification on the correct answer. The question is, which indicator of trustworthy measurement would be impacted by an incomplete operational definition? The answer choices are replication, accuracy, validity, and reliability. The correct answer is validity. Validity relies on three things: Measuring the relevant dimension of the behavior. Directly measuring the target behavior. Ensuring that the data is representative of the target behavior as it occurs in the conditions of interest. A complete operational definition would help to ensure that the relevant dimension of the behavior is clear, and therefore, more likely to be measured. A complete operational definition informs us of direct measurement opportunities by establishing the conditions of interest and therefore, also helping to ensure that the data represents these relevant conditions. The key point is that validity means we’re measuring the right thing. By having a complete understanding of the behavior of interest, we know what is being measured, which is what the operational definition gives us. 6th Edition TCOC. Measurement, Data Display, and Interpretation C.1 Create operational definitions of behavior. C.8 Evaluate the validity and reliability of measurement procedures.
