Roxanne was doing research to determine the best treatment for a new client who is suffering from dissociative identity disorder. In doing so, she gathered information from several different research studies that focused on the treatment of dissociative identity disorder. Then, she used statistics to combine the results of these studies and determined the best approach. The process that Roxanne used is called randomized clinical trial. meta-analysis. regression toward the mean. evidence-based practice. outcome research.

b. meta-analysis

Explanation:

Meta-analysis is a process whereby the results of different scientific studies are statistically computed. The scientific studies must be on a particular subject and doing this will provide the researcher with a better knowledge of the real truth and best method from the findings of the various research. In performing a meta-analysis, a research question is first formulated, different literature on the subject of interest is sourced, studies are selected, dependent variables of interest are chosen, and then a meta-analysis model is also chosen. The type of research Roxanne is performing fits into the meta-analysis model because,

1. She aims at finding the best treatment for a disease.

2. She can only know the best treatment when she statistically computes the findings from different research studies.

3, The scientific studies she sourced are from a particular subject which is the dissociative identity disorder.
