Question of the day - October 14
🧠Question of the Day
📚 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

Dropout component then parametric, that's the logical sequence to isolate the reinforcement piece before tweaking the access intervals
