What experimental design would be appropriate for a client who swallows large items?

• A. Multiple baseline design
• B. Alternating treatments design
• C. Cumulative record design
• D. Single-subject design

Answer: (B)

When addressing the issue of a client who swallows large items, an alternating treatments design is particularly appropriate because it allows for the comparison of two or more interventions in a single context or setting. This type of design can effectively evaluate the impact of different strategies to reduce the behavior of swallowing large items by alternating between these interventions. The rapid switching between conditions helps in determining which intervention might be more effective, as it provides immediate feedback about their relative effectiveness. This design is beneficial in situations where behaviors occur frequently and where it is necessary to assess the efficacy of different treatments efficiently without the lengthy wait of seeing effects over time, which would be the case in a more traditional design like a multiple baseline or reversal design. In this context, the ability to quickly switch between interventions and visually assess their impact can yield valuable data on the most effective approach for the client’s unique needs. Using an alternating treatments design also minimizes potential practice effects that might occur with other designs, ensuring that the behavior is assessed in varied circumstances while still being closely monitored. This dynamic measurement makes it a strong choice for addressing behaviors that require swift intervention, such as swallowing dangerous items.
