Chapter 13: Personality Disorders
Personality disorder (PDs): a heterogeneous group of disorders that are coded on
axis
II
of the DSM. They are regarded as long-standing, pervasive and inflexible patterns
of behaviour and inner experience that deviate from the expectation of a person’s
culture and that impair social and occupational functioning (some but not all cause
emotional distress)
An actual personality disorder is defined by extremes of several traits and by the
inflexible way these traits are expressed
They are often rigid in their behaviour and cannot change it in response to changes
in the situation they experience
Individuals would not be diagnosed as having personality disorders unless the
patterns of behaviour were long-standing, pervasive and dysfunctional
Often co-morbid with axis I disorders
Classifying Personality Disorders: Clusters, Categories and Problems
The reliability of personality disorder diagnoses have improved because of 2
developments
o The publication of specific diagnostic criteria
o The development of structured interviews specially designed for assessing
personality disorders
Test-rests reliability is also an important factor for evaluation
It is often difficult to diagnose a single, specific personality disorder because many
disordered people exhibit a wide range of traits that make several diagnoses
applicable
Personality disorders can be construed as the extremes of characteristics we all
possess
(Livesley, Schoroeder, Jackson and Jang) personality disorder is a failure or inability
to come up with adaptive solutions to life tasks...
o To form stable, integrated and coherent representation of self and others
o To develop the capacity for intimacy and positive affiliations with other
people
o To function adaptively in society by engaging in prosocial and cooperative
behaviours
