part 1
Please respond to the following:
Provide a discussion that compares and contrasts the differences between single case research designs (SCRD) and group research designs used to investigate the effectiveness of interventions (e.g., studying a problem in an applied setting).
Make sure to include a detailed description of the characteristics of SCRD, including the considerations regarding internal and external validity.
Explain the primary purpose of a comparative, component, and parametric analysis, and provide an original example of how each might be used as part of a single case research design and incorporated purposefully into a practical intervention plan.
part 2
Understanding the “when” and “why” of a research design is an important part of organizing and reporting intervention results. Now that you have gained some insight into some common designs used in research and practice, it is time to put that knowledge to work.
Please respond to the following:
Explain the guidelines for utilizing a Withdrawal and Changing Criterion design.
Provide a short discussion on the internal and external validity issues as well as an overview of the advantages and disadvantages of each design.
Identify a hypothetical target behavior (dependent variable) for change and a possible intervention (independent variable) that you would use with either the withdrawal or changing criterion design.
Operationally define the target behavior in observable and measurable terms and provide a rationale to justify the use of your chosen design for the target behavior and intervention that you have identified.
