Shifting Diagnostic Models
- Personality disorder diagnoses are shifting from a categorical to a dimensional model.
- The categorical model, like being pregnant or not, has limitations in fully capturing the complexity of personality disorders.
BPD Diagnosis and Complexity
- Clinicians currently use the DSM-5's Section 2 to diagnose BPD, checking for five of nine criteria.
- While effective, this categorical approach recognizes the co-occurrence of BPD with other disorders like depression, anxiety, and substance abuse, leading to complex treatment.
BPD and Personality Functioning
- BPD is the most diagnosed personality disorder because it reflects a common factor in personality functioning.
- This 'personality quotient' assesses how well individuals manage themselves and interpret others in social interactions.
