principal diagnoses A+ Writers |

Based on the material presented in the Case Study of Bill:

  1. Provide the DSM-5 differential diagnoses for Bill, including a listing of “Other Factors,” and support your decision process with a brief narrative.
  2. Refer to the two ICD-10-CMappendices in your DSM-5 text, pages 839–862 and 877–896 and detail any differences in the diagnosis that you might find if you were to use the ICD-10 to arrive at the diagnosis or diagnoses. (As this is your first look at the comparison between the ICD-10 and the DSM classification systems, you may want to take a little time to understand how these systems relate to each other.)
  3. Explain the etiological factors that you think are relevant in this case along with their reasons, keeping the diathesis-stress model in mind. You will need to do some research to clearly explain and support your reasons for suspecting these etiological factors.
  4. List the three primary issues that need to be addressed in a treatment plan for Bill.
