What is the research tactic for examining two or more elements of a treatment package called?

The correct answer is component analysis, which refers to the method used to assess the individual impact of different elements within a treatment package. This approach is essential in determining how each component contributes to the overall effectiveness of an intervention. By isolating and evaluating each element, researchers can identify which aspects are necessary for achieving desired outcomes and which may be redundant or less effective.

This technique is valuable in contexts like special education, where various strategies may be combined in a treatment plan. Understanding the role of each component can lead to more effective and streamlined interventions tailored to individual student needs. Such detailed analysis helps educators and clinicians optimize practices based on empirical evidence, ensuring that they employ the most impactful strategies for their students.
