criteria for a PD, and traits of several personality
disorders are present – but the criteria for any specific
Other Specified Personality
PD are not met
Disorder and Unspecified

,Personality Disorders - Clusters
The personality disorders are grouped into three clusters – based on descriptive similarities
1. Cluster A – Odd, Eccentric
- Includes paranoid, schizoid, and schizotypal PDs
2. Cluster B – Dramatic, Emotional, Erratic
- Includes antisocial, borderline, histrionic, and narcissistic PDs
3. Cluster C – Anxious, Fearful
- Includes avoidant, dependent, and obsessive-compulsive PDs
Individuals frequently present with co-occurring PDs from different clusters
Dimensional Models for Personality Disorders
The diagnostic approach used – represents the categorical perspective that PDs are qualitatively
distinct clinical syndromes
General Personality Disorder
Diagnostic Features
Personality Traits – enduring patterns of (1) perceiving, (2) relating to, and (3) thinking about
the environment and oneself
, - Exhibited in a wide range of social and personal contexts
Only when personality traits are (1) inflexible and (2) maladaptive – and cause sig functional
impairment or subjective distress
- They constitute personality disorders
Diagnosis of PD
The diagnosis of PDs – requires an evaluation of the individual’s long-term patterns of
functioning
- Particularly – personality features must be evident by early adulthood
The personality traits that define these disorders – must also be distinguished from characteristics
that emerge in response to
(1) Specific situational stressors
(2) More transient mental states – e.g., bipolar, depressive, or anxiety disorders;
substance intoxication
The clinician – should assess the stability of personality traits over time – and across different
situations
- Often necessary to conduct more than one interview – and space these over time
Assessment – can be complicated by the fact that the characteristics that define a PD – may not
be considered problematic by the individual – i.e., the traits are often ego-syntonic
- Overcome this – by supplementary info from other informants
Development and Course
The features of a PD – usually become recognizable during adolescence or early adult life
By definition – a PD is an enduring pattern of thinking, feeling, and behaving – that is relatively
stable over time
1. Some types of PD – i.e., antisocial and borderline PDs – tend to become less evident
or to remit with age
- This is less true for some other types – e.g., obsessive-compulsive and schizotypal
PDs
