Axis V: 50
Axis I: Major Depression
Axis II: Avoidant Personality Disorder

Categorical vs. Dimensional?
Medical model = categories E.g. HIV+ or HIV- Relevant for psychopathology? E.g. depression
An “extreme” of bad mood

Criticisms of DSM Diagnosis
Fuzzy categories Reliability issues (e.g., personality disorders) Labeling Inform treatment? Cultural appropriateness
Virgil is a 55-year-old African American man whose wife died of cancer 2 years ago. He has become sullen & withdrawn, spending less time at his hobbies and speaking less to coworkers at his job at a supermarket. He still attends the church to which his wife always accompanied him, and he is still very well-liked, but he tends to arrive in time for the service and leave soon afterward, politely nodding at friends who wish him well.
Virgil’s daughter and coworkers are the first to notice the lapses in concentration and the more-frequent occasions where Virgil’s memory fails him. At first these are of little consequence – forgetting to add milk to his coffee, or forgetting to sign a form at work. But soon these lapses become more problematic – missing his heart medication with some regularity, or misplacing a box of a shipment of perishables. Concerned, his daughter convinced Virgil to seek professional help
