Since dissociative identity disorder is a rare disorder, it would be difficult to find a large enough sample size for an experimental or correlational design. Naturalistic observation design also may not be effective since the behavior in question may not occur frequently. Therefore, a case study design would be most useful as it can provide in-depth information about a single individual or a small group of individuals who have the disorder. Case studies can provide detailed information about symptoms, causes, and treatment, which can be useful for developing hypotheses for future research.
