Advantages of Dimensional Model (FFM)
- Resolution of classifactory dilemmas
- Does not rely on arbitrary cut offs
- Retention of detailed info
- Suits patients who are not prototypical
- Diminishes stereotyping by providing more precise info
- Flexibility (can go to categorical from dimensional back not vice versa)

- A problem for both research & practice
- May impede the ID of discrete etiologies & treatments
