Not everyone agrees with renaming the unstable set “borderline” because the word:
- has always been ambiguous
- does not connote or denote any specific criteria or characteristic of patients who bear the label
- brands the patient as untreatable, defiant, or just “bad.”
Post-DSM-III: Where are we now?
From DSM-III evolved the hope that psychiatry could describe valid, well-defined diagnostic categories. Lost in the DSM-III enthusiasm was the fact that the categories were based upon theoretic constructs—theories no more or less valid than other theories that had preceded them. Because some of these categories were based upon empiric data— such as the Spitzer et al study—these diagnoses were perceived as more valid and more related to pathophysiology and perhaps genotype than prior constructs and definitions.
In the 1980s and early 1990s, a proliferation of studies attempted to examine the validity and reliability of DSM-III definitions, and BPD became the most studied of the personality disorders. The BPD concept took hold, even though several studies did not support it and despite refinements in subsequent DSM editions (Box 3).
One refinement in the BPD construct applied to transient psychotic or psychotic-like experiences, including dissociative phenomena. Yet questions remain about the duration of these transient episodes (Box 4).
Categorical versus dimensional
The categorical concept of BPD is facing new scrutiny,26,27 as recent studies have implied that biological disturbances may be spread across a number of personality disorders.28 If biological findings are found to be more closely allied with genotypic variations (alleles),29 then perhaps a dimensional classification system is needed for BPD and personality disorders in general.
On the other hand, categories provide a well-defined population that we can study and try to delineate from other populations, whereas dimensions—while perhaps closer to the reality of clinical presentation—may allow too much variability for research to proceed without confounding restraints.
BPD will continue to evolve, as will all psychiatric diagnostic categories, but the need to modify its definition does not negate its usefulness and clinical applicability. Most of our patients do not read the DSM before coming to us. They present with symptom complexes and problems that demand that we listen to what they say and understand who they are while we also try to fit them—as best we can—into categories or dimensions30 that help us choose the most appropriate interventions.
