What best describes Multiple Probe Design in Single Case Research Design?

• A. Continuous monitoring of a behavior at all times
• B. Intermittent data collection at specified times
• C. Introduction of multiple interventions at once
• D. Comparison of behavioral changes using a control group

Answer: (B)

Multiple Probe Design is characterized by intermittent data collection at specified times rather than continuous monitoring. This approach allows researchers to assess the effects of an intervention on behavior over time while minimizing the burden of constant data collection.

In this design, data is collected at various intervals across different baselines or conditions, enabling practitioners to gauge the stability of a behavior before and after the introduction of an intervention. This method is particularly useful when assessing behaviors that are not expected to change dramatically within a short period. By focusing on intermittent data collection, Multiple Probe Design facilitates the evaluation of an intervention's effectiveness without requiring constant observation, which can often lead to data overload and potential observer fatigue.

The focus on specific data collection points allows for a clearer understanding of changes in behavior in relation to the intervention, making it an efficient approach in single-case research design.
