Table 1.
Major limitations of current operational categorical approach to diagnosis
| - | The focus is on episode rather than lifetime experience of psychopathology |
| - | Hierarchies lead to loss of information |
| - | Boundaries between diagnostic categories are often arbitrary |
| - | Boundaries between categories often require substantial subjective judgement |
| - | Available diagnostic categories are relatively unhelpful in distinguishing severity |
| - | Sub-clinical cases are usually not accommodated usefully |
| - | “Not Otherwise Specified (NOS)” categories are highly heterogeneous |
