PART 2:

"Peggy, a 17-year-old female, was referred by her pediatrician to a child psychiatry clinic for evaluation of an eating disorder. she had lost 10 pounds in 2 months and her mother was concerned... At the clinic she stated that she was not trying to lose weight, had begun to sleep poorly about 2 months ago unless she had several beers, and that she and friends "got trashed" on weekends. Her relationship with her parents was poor; she had attempted suicide a year previously with aspirin and was briefly hospitalized. The day before this evaluation she had taken a razor to school to try and cut her wrists, but it was taken away by a friend. She admitted being depressed and wanting to commit suicide and finally told of discovering that she was pregnant 4 months earlier. Her boyfriend wanted her to abort, she was ambivalent, and then she miscarried spontaneously about 2 months after her discovery. After that, "it didn't really matter how I felt about anything"."

Revisit the case of Peggy (typed above). Hypothesize about how the diathesis-stress model might apply to her.
