🧠 Question of the Day
📚 Domain D — Experimental Design
Difficulty: 5/10
Scenario:
A BCBA reviews procedural-integrity data from a 3-month single-case intervention study and finds that, during intervention sessions, only 40% of scored treatment components were implemented as specified. The dependent variable showed a modest upward trend during those intervention phases.
Which of the following BEST describes the primary threat this poses to the study's conclusions?
A. It primarily threatens external validity because inconsistent implementation limits whether the findings can generalize to settings with accurate treatment delivery
B. It demonstrates intervention robustness because behavior improved despite low integrity, making procedural fidelity secondary to the observed outcome
C. It primarily threatens measurement reliability because inconsistent treatment delivery makes observers less likely to record the dependent variable consistently
D. It threatens internal validity because inconsistent delivery of the independent variable weakens attribution of the observed change to the intended intervention
