To prepare: Focus on the complex but precise definition of a mental disorder in the DSM-5 and the concept of dimensionality both there and in the Paris (2015) and Lasalvia (2015) readings. Also note that the definition of a mental disorder includes a set of caveats and recommendations to help find the boundary between normal distress and a mental disorder.
Then consider the following case:
Ms. Evans, age 27, was awaiting honorable discharge from her service in Iraq with the U.S. Navy when her colleagues noticed that she looked increasingly fearful and was talking about hearing voices telling her that the world was going to be destroyed in 2020. With Ms. Evans’s permission, the evaluating [social worker] interviewed one of her closest colleagues, who indicated that Ms. Evans has not been taking good care of herself for several months. Ms. Evans said she was depressed.
The [social worker] also learned that Ms. Evans’s performance of her military job duties had declined during this time and that her commanding officer had recommended to Ms. Evans that she be evaluated by a psychiatrist approximately 2 weeks earlier, for possible depression.
On interview, Ms. Evans endorsed believing the world was going to end soon and indicated that several times she has heard an audible voice that repeats this information. She has a maternal uncle with schizophrenia, and her mother has a diagnosis of bipolar I disorder. Ms. Evans’s toxicology screen is positive for tetrahydrocannabinol (THC). The evaluating [social worker] informs Ms. Evans that she is making a tentative diagnosis of schizophrenia.

300- to 500-word response in which you discuss how a social worker should approach the diagnosis. In your analysis, consider the following questions:
· Identify the symptoms or “red flags” in the case study that may be evaluated for a possible mental health disorder.
· Should the social worker have shared this suspected diagnosis based on the limited assessment with Ms. Evans at this time?
· Explain the potential impact of this diagnosis immediately and over time if the “tentative” diagnosis is a misdiagnosis.
· When may it be appropriate to use a provisional diagnosis?
· When would you diagnosis as other specified and unspecified disorders?
