CASE SUMMARY

Provide information and empirical evidence to assist in making diagnostic, etiological, and treatment decisions

• What symptoms is the patient currently exhibiting and what diagnostic symptom clusters do these belong to?
• What is the most accurate DSM V diagnosis for these symptoms? What led you to rule out other possible diagnoses?
• What information (if any) is still needed to strengthen the diagnosis? How will you obtain this information?
• What factors may have contributed to the onset/etiology of the disorder?
• What current factors might be maintaining the disorder?

TREATMENT PLAN

• What are your treatment recommendations and why?
• Given the diagnosis, what is the scientific evidence supporting this treatment recommendation?
• If there have been previous unsuccessful treatments, how will your plan differ?
• Are there factors that might stand in the way of treatment success? If so, how will you get around them?
• Are there other individuals (e.g. family members, outside health care professionals) who will have to be incorporated into the treatment plan?
• How will you judge the success or failure of your treatment approach?

CASE CONCEPTUALIZATION

• Based on the case details, provide a plausible, theory-based hypothesis for the etiology and maintenance of the symptoms ("case conceptualization"). What scientific evidence supports this hypothesis?
• How does this case conceptualization lead to your treatment plan?
• What future evidence would support or disprove your case conceptualization?
