Select one of the methods used to evaluate change and improvement with clients/client systems (single subject, pretest/posttest or other). Provide a rationale for the evaluation method you selected. Describe the method and how you would facilitate using that method to collect data to assess change and improvement. Note: Most students use a pre and posttest format using a scale or assessment instrument (AB model). Other methods can be used. If you did not do pre and post testing in your internship setting, you have my permission to make up the information of what you would have done if you could. Some instruments like the Beck Depression Instrument have a strong evidence base. Other tools like those developed in clinic for local use or some scale do not. If you have a choice, pick an instrument with a strong evidence base.
