
DSM – Categorical Approach

Based on the medical model

Disorder is present or absent
Assumptions of the DSM



Personality pathology is suited to be
classified into discrete types or disorders
These disorders group themselves into
three clusters
The diagnostic criteria naturally fall into
the particular personality disorders to
which they have been assigned
Empirical Evidence doesn’t support these assumptions!!!
David Klonsky – University of Virgina
“the DSM practice of putting expert opinions into writing and
only then conducting tests of reliability and validity cannot
lead to an acceptable classification system. Rather it directs
scientists to conduct research on, and practitioners to put
their trust in, diagnostic labels that may or may not map onto
valid constructs that exist in nature. Instead, researchers
must turn to objective, empirical methodologies to discover
the dimensions or personality pathology, letting the data fall
where they may and letting the data determine how
personality disorder is best classified”
John Livesley - UBC


Dimensional Assessment of Personality
Pathology Basic Questionnaire (DAPP)
4 Dimensions: Emotional Dysregulation;
Dissocail Behaviour; Inhibitedness;
Compulsivity
“ …the evidence on this point is so
unequivocal that the only issue to explain
is the field’s reluctance to accept empirical
evidence”
~ W. John Livesley, (2000) Journal of
Personality Disorders, 14, 2, p. 139-140.
The “Big 5” Personality Traits





Openness to experience
Conscientiousness
Extraversion
Agreeableness
Neuroticism
 personality disorders represent
extreme variations of OCEAN
Advantages of Categorical
System
Ease in conceptualization and
communication
 Familiarity
 Consistency with clinical decision
making

Disadvantages of the Categorical
Approach
Complex and cumbersome
 Arbitrary cut-off points
 Loss of important information

Advantages of the Dimensional
Model



Resolution of a variety of classification
dilemmas
Retention of Information
Flexibility
Disadvantages of the
Dimensional Approach


Lack of clinical utility?
Lack of familiarity?
Bottom line: not too many disadvantages
and most researchers favor it – likely to be
adopted in DSM-V
