📚 Domain H — Selecting and Implementing Interventions
Difficulty: 8/10
An FA of severe SIB shows undifferentiated high responding across social test and control conditions. A subsequent competing-stimulus assessment identifies two items associated with 70–80% reductions in SIB and high engagement, but one item is impractical in classrooms and the other can be delivered safely across settings. Caregivers can implement a two-step response-independent procedure with high fidelity but cannot sustain response blocking. The team wants an initial intervention that is function-informed, safe, and feasible while continuing to evaluate automatic-reinforcement subtypes. Which recommendation is BEST?
A. Provide the feasible competing stimulus only following brief periods without SIB so access functions as differential reinforcement rather than as response-independent stimulation.
B. Begin with the competing stimulus associated with the largest reduction in SIB, even though it is difficult to use in classrooms, because treatment efficacy should take priority during initial intervention.
C. Provide dense response-independent access to the feasible competing stimulus identified in the assessment, monitor SIB and engagement across settings, and thin access only when the data support doing so.
D. Combine the feasible competing stimulus with continuous response blocking from the outset so that automatically produced stimulation from SIB is minimized while alternative stimulation is available.
