What does a Research Question on effectiveness typically evaluate?

• A. The impact of independent variables
• B. Which intervention is more effective
• C. Continuous vs. Discontinuous measurement
• D. Estimates of behavior occurrence

Answer: (B)

A research question focused on effectiveness aims to evaluate which intervention is more effective in achieving particular outcomes. This involves comparing different strategies, treatments, or interventions to determine their relative impact on the target behavior or population. In essence, the goal is to identify the most successful approach to facilitate behavior change or improvement. Effectiveness studies often utilize various methodologies to assess the success rates of these interventions and can provide valuable insights into best practices in special education and behavior analysis.

While the other options relate to important aspects of research methods, they do not precisely capture the essence of evaluating effectiveness. Assessing the impact of independent variables involves looking at how these variables influence the dependent outcomes but does not directly focus on comparing interventions. Continuous versus discontinuous measurement addresses methodologies for data collection rather than assessing the impact of one intervention over another. Lastly, estimating behavior occurrence pertains to measuring frequency or patterns of behavior but does not specify which intervention may be more effective. Thus, option B focuses on the key aim of determining the superiority of one intervention compared to alternatives.
