What is the goal of matched pairs design?

• A. To measure client satisfaction before and after treatment
• B. To equate two groups based on relevant criteria for comparison
• C. To randomly assign subjects to treatment conditions
• D. To evaluate multiple interventions on a single subject

Answer: (B)

The goal of matched pairs design is to equate two groups based on relevant criteria for comparison. This design is particularly useful in experimental research where the objective is to minimize the effects of confounding variables that could influence the results. By matching pairs of subjects based on specific characteristics (such as age, gender, or baseline measurements), researchers can ensure that each group is similar in these important aspects, thereby enhancing the validity of the findings. This controlled setup allows researchers to more accurately assess the effects of the treatment or intervention being studied, as the only significant differences between the groups should arise from the treatment itself. In comparing outcomes, it becomes clearer whether observed effects are due to the intervention rather than pre-existing differences between the groups. This method is essential in many areas of research, including music therapy, where individual differences can be significant.
