Personality Disorders Flashcards
What is personality?
A persona (plural personae/personas): Latin for ‘mask’ Outward or surface aspect presented to audience
What determines personality?
NATURE: Innate Temperament (disposition): Genetic & constitutional
NURTURE: Character: Acquired values & attitudes
DSM-5: What is a Personality Disorder?
–> usually onset very early in childhood & develop into PDs
Enduring pattern of inner experience and behaviour that:
• Deviates markedly from the individual’s culture
• It is pervasive, inflexible & stable over time (NOT IN EPISODES, STABLE OVER TIME)
• Leads to distress or impairment
The pattern is manifested in two or more areas: (NOT ALL ARE NEEDED, ONLY 2 OR MORE)
• Cognition (ways of interpreting self, others & events)
• Affect (range, intensity, stability & appropriateness of
emotional response)
• Interpersonal functioning
• Impulse control
Personality Disoders - Core features (Millon, 1981)
- Functional inflexibility
- Failure to adapt to situations: rigid response - Self-defeating
- Behavioural responses damaging - Unstable in response to stress
- Emotional, behavioural & cognitive instability (especially in borderline, harming themselves)
(ALSO LACK OF INSIGHT, failure to recognise dysfunctional aspect of personality)
Two classification systems: DSM-5 & ICD-10
DSM-5
• 10 personality disorders categorised in 3 clusters
ICD-10
• 9 personality disorders but not clustered & with slightly
different labels –> E.g., Antisocial – Dissocial & Obsessive-compulsive - Anankastic
Cluster A
Odd/Eccentric –> often high introversion
- Paranoid
- Schizoid
- Schizotypal
Cluster B
Dramatic/emotional/erratic • Antisocial • Borderline • Histrionic • Narcissistic
Cluster C
Anxious/Fearful
- Avoidant
- Dependent
- Obsessive-compulsive
Categorical vs. dimensional approach
DSM-5 represents a categorical approach
• assumes that personality disorders represent distinct clinical syndromes
• Advantages: clarity and ease of communicating information
• Disadvantages: difficult to distinguish the threshold where the person goes from a ‘normal’ personality traits through to meeting criteria for a personality disorder
• A gradual move towards a dimensional approach to
classifying personality disorders
–> Dimensional approach acknowledges traits on a spectrum
Variable nature
Variable nature of area between clusters, diagnosis very dependent upon psychiatrists subjective opinion
heterogeneity within diagnoses
diagnostic unreliability
lack of robust scientific evidence
DSM-IV: AXIS I vs. AXIS II
AXIS I: Major clinical disorders with acute symptoms that need treatment
AXIS II: Personality disorders (& intellectual disabilities)
• early age of onset
• enduring and more pervasive effects on daily
functioning
• involvement of self & identity
• presumed poorer self-awareness
• lower treatment response
DSM-3 & 4 used 2 axis approach, DSM-5 uses single axial model
Paranoid PD - Cluster A
Not delusional –> distinguishes from schizophrenia
Consistent & pervasive pattern of distrust, suspiciousness
and prolonged grudges held:
• Believes others intentionally exploit, harm or deceive them
• Reluctance to disclose personal information for fear it may be used against them
• Severely sensitive to criticism & threat => hypervigilant for signs of others to harm them
• Misinterprets comments to indicate concealed, hidden or malevolent intent or motivation
• Hostility, aggression & anger to perceived insults
• Jealousy (distrust & misinterpretation)
–> Two thirds meet criteria for other PDs e.g., Schizotypal, Narcissistic, Borderline & Avoidant
Paranoid PD Thought Processes
Assumptions: People are malicious & out to get you, They will take advantage if they can, You will be okay as long as you do not let your guard down
Cognitions: Expectancy of hostility, Vigilance, Guardedness, Confirmatory evidence, Lack of trust
Interpersonal Behaviour: Suspiciousness & guarded against closeness, resentful, failure to trust others, Tendency to elicit hostility & distrust from others
Schizoid PD - Cluster A
- Like talking through glass wall, can see but not connect
Engage in solidarity activities ‘computer nerds’, not anxious just no interest in sociality
Detachment and disinterest in social relationships
• withdrawal into internal world to avoid affect and
maintain distance from others
• Sees others as intrusive and controlling
• Flatness of affect: coldness, aloofness, self-absorption,
social ineptitude or conceit
• Unresponsive to social criticism: sexually apathetic
reflecting incapacity to form interpersonal bonds
• Anhedonia –> lack of ability to feel happiness
• Comorbid with schizotypal and avoidant PDs
Schizotypal PD - Cluster A
Eccentric/odd, often in fringe groups
Marked interpersonal deficits, behavioural eccentricities
and distortions in perception & thinking (that do not meet
criteria for schizophrenia) • e.g. magical thinking, extreme superstition, belief in paranormal phenomenon, bodily illusions, sensory alterations
• Odd thoughts & speech patterns: vague, abstract but
retains coherence
• Often seek treatment for anxiety, depression & affective
dysphoria (constricted or inappropriate affect)

schizoid PDs
Antisocial PD - Cluster B

Repeated reckless disregard for others
• Victimizing & blaming others for inadequacies
• Shallow & manipulative interpersonal relationships
• Self-centered focus & failure to adhere to regulations
• Impulsive, aggressive, charismatic, deceitful
• Experience guilt & depression but lack capacity to
empathize
• Anti-social behaviour: criminal behaviours may or may not be present (DON’T HAVE TO BE)
• Co-morbidity with borderline, narcissistic, histrionic &
schizotypal PDs
Borderline PD - Cluster B: Primary disturbances
Emotional lability, often self-harming, can be used for manipulation & attention, splitting & developing conflict for enjoyment, very possessive

• Reflects shared impulsivity/disinhibition & affective
instability personality traits
• Arguably associated with the greatest levels of
disability of all the PDs
Histrionic PD - Cluster B
attention seeking, conversion of psychological angst into physical symptoms, very dramatic & self-centred
Roots in the concept of hysteria: conversion
disorders, emotional instability, anxiety & phobias
