paranoid, schizoid, and schizotypal
oddness and avoidance of social contact

What are some of the symptoms of Schizotypal PD?
Odd beliefs or magical thinking (e.g., belief they have telepathic powers, superstitious, clairvoyance, ‘others can feel my feelings’
Recurrent illusions (e.g., sense the presence of a force not actually there – “I felt that my dead mother was in the room with me.”), depersonalization, derealization.
Odd speech (using words in unusual or unclear fashion, e.g., digressive, vague, overelaborate)
Ideas of reference (misinterpret event as having particular personal meaning)
Suspiciousness or Paranoid ideation
What is the etiology of schizotypal PD?
Genetically linked to schizophrenia
Perhaps less severe variant
Could be linked to a history of PTSD and childhood maltreatment
What are the characteristics of Borderline PD?
core features are impulsivity and instability in relationships, mood, and self-image
attitudes and feelings toward others vary dramatically
emotions are erratic and can shift abruptly
argumentative, irritable, sarcastic, quick to take offence, etc.
Can be transient episodes of paranoia, dissociation
Very high neuroticism
Low on trust, compliance (agreeableness)
Dichotomous thinking (splitting)
What are the three main dimensions of Borderline PD?
Three main dimensions:
Inappropriate anger, drastic mood shifts
feelings of emptiness
Unstable and intense relationships
Efforts to avoid abandonment
Impulsive self-damaging behaviors
Attempts at self-mutilation or suicide
What are the biological theories of Borderline PD?
Strong genetic component found in twin studies
Heritability of impulsivity and affective instability
Reduced response to serotonin in orbital, ventromedial and cingulate cortices linked to impulsive aggressivity
Increased noradrenergic responsiveness linked to affective instability
poor functioning of the frontal lobes
What are the psychosocial theories of Borderline PD?
Negative experiences in childhood: abuse, neglect, separation or loss, trauma
What are the Diathesis-stress theories of Borderline PD?
Linehan’s diathesis-stress theory
Genetic/biological diathesis: affective instability and impulsivity traits
Stress: trauma, parental failure or psychopathology, loss/rejection
What are other etiologies of Borderline PD?
What are the treatments for Borderline PD? How do therapists deal with the tendency for patients to have troubles establishing trust; alternatively idealizing then vilifying them?
Dialectical behavior therapy: tolerance of negative affect, interpersonal skills, emotion regulation
Often uses group therapy
combines client-centered acceptance with a cognitive-behavioural focus
Object Relation: strengthen ego, address directly the splitting defense
SSRIs useful for mood
Antipsychotic (low doses)
What are the characteristics of Histironic PD?
overly dramatic and attention-seeking
use physical appearance to draw attention
display emotion extravagantly
overly concerned with their attractiveness
inappropriately sexually provocative and seductive
speech may be impressionistic and lacking in detail
What are the characteristics of Narcissistic PD?
grandiose view of own uniqueness and abilities
preoccupied with fantasies of great success
require almost constant attention and excessive admiration
envious of others
arrogant, exploitive, entitled
What are the characteristics of Antisocial PD?
Two major components: 1) Conduct disorder present before 15 and 2) Pattern of anti-social behaviour continues in adulthood
irresponsible and anti-social behaviour
work only inconsistently
impulsive and fail to plan ahead
What is psychopathy?
Key characteristic— poverty of emotions both positive and negative
lack of remorse
no sense of shame
manipulates others for personal gain
lack of anxiety
What is the relationship and differences between antisocial PD and psychopathy?
You can have APD and not be psychopathic but you can't be psychopathic and not have ADP.
Major distinction appears to be in symptomology.
“Lack of remorse,” a core symptom of psychopathy, is not required for diagnosis of APD.
What are the etiologies for APD and psychopathy?
Role of the Family:
Lack of affection
Severe parental rejection
Inconsistencies in disciplining
Failure to teach child responsibility toward others
Criminality and APD have heritable components
(twin and adoption studies)
What is different about psychopaths' emotions?
unresponsive to punishments / no conditioned fear responses
have higher than normal levels of skin conductance in resting situations
skin conductance is < reactive when confronted or anticipate intense or aversive stimuli
heart rate normal under resting conditions but in when anticipating intense or aversive stimuli heart rate higher than norms
Response Modulation, Impulsivity, and Psychopathy
slow brain waves and spikes in the temporal area
< activity in the amygdala/hippocampal formation
How was conduct disorder diagnosed?
Presence of at least 3 of the following:
Aggression – people and animals
Truancy or staying out all night (before 13)
How does Cleckley describe psychopathy?
Lack of remorse
Poverty of emotions (positive and negative)
Inadequate conscience development
Irresponsible and impulsive behavior
Ability to impress and exploit others
What are Hare's two major factors of psychopathy?
Affective/interpersonal: selfish, remorseless individual with inflated self-esteem and who exploits others.
Superficial charm, Grandiose sense of self-worth, Manipulative, Lack of empathy, Shallow affect
Antisocial lifestyle (behavior): marked by impulsivity and irresponsibility.
Failure to conform, Aggression, Deceitful/lying, Disregard for others
What are the biological theories of psychopathy?
Amygdala involved in aversive conditioning and response to fearful and sad faces
Psychopathy associated with:
Reduced amygdala volume
Reduced amygdala response to negative stimuli
What are the psychosocial theories of psychopathy? (not previously mentioned)
Fathers likely to have antisocial personalities.
What is the treatment for APD and psychopathy?
Usually unsuccessful, due in part to:
Lack of motivation
Early intervention may be more effective.
Antisocial behaviour decreases in middle age.
What is the Stress reactivity theory of psychopathy?
Convicted psychopaths usually found to have:
Lower autonomic stress reactivity
Lower resting state autonomic activity
Thought to play a role in development of psychopathy.
Not seen in “successful” psychopaths.
What is the Low-fear hypothesis of psychopathy?
Low fear response: skin conductance to unpleasant events
Failure to avoid punishment, learn from it, consequences don’t lead to develop conscience
What is the Frontal hypothesis theory?
Executive dysfunction/function deficits thought to underlie some psychopathic features.
Limitation - Studies supporting the frontal hypothesis mainly included violent offenders
No executive dysfunction found in “successful psychopaths”
What are the characteristics of Avoidant PD?
fearful in social situations
keenly sensitive to possibility of criticism, rejection, or disapproval
reluctant to enter relationships unless sure will be liked
What are the characteristics of Dependent PD?
overly dependent on others (sense of autonomy)
intense need to be taken care of
uncomfortable when alone
subordinate own needs
What are the characteristics of Obsessive-Compulsive PD?
perfectionistic approach to life
preoccupied with details, rules, schedules, etc.
serious, rigid, formal, and inflexible
unable to discard worn out and useless objects
does not include the obsessions and compulsions that define OCD
What is the etiology of cluster C PDs?
Little data exist
Speculation about causes has focused on parent-child relationships
What are the limitations in studies of the etiology of psychopathy and APD?
1. harsh or inconsistent disciplinary practices could be reactions to child’s anti-social behaviour which may in turn fuel development of full blown antisocial behavior.
2. many individuals who come from disturbed backgrounds do not become psychopaths
