special issues of personality disorders
what is personality?
characteristic ways that a person think and behave across situations
what is a personality disorder?
- personality disorders, unlike anxiety or major mood disorders are things that we have (YOU are the disorder) -> the most controversial section of the DSM
- no episodic moments,
- with all the other disorder, individual experiences distress, it is not always the case with personality disorders (maybe experienced to those around them, which is more unique to PD’s )
- they are less likely to report experiencing distress or impairment
special issues
gender issues
Gender issues
- Men and women tend to be diagnosed with different disorders
- Due to biased criteria, biased tools, or biased clinicians?
- men are tend to be diagnosed with more aggressive, perfectionistic, self assertive, or detached symptoms
- women are more likely to be diagnosed with symptoms relating to submissive, emotional, and insecure
- issue of criteria? Biased? Clinician biased?
- biased clinicians seems to be the driving force, they feed into stereotypes
special issues
age of onset?
Exist in childhood?
Diagnose in late teens or young adulthood
- controversial as well
- childhood, personality that they ever had
- typically you would diagnose early teen, early adulthood
- issues with diagnosing a child with personality disorder -> they’re just developing their personality
- stigmatization, shame, when you assign a label to a child, it will def influence the child
cluster A
Defining characteristics: Odd and eccentric behaviours
Disorders
Paranoid PD : Life% = 2%-5%
Schizoid PD : Life% = 3%-5%
Schizotypal PD : Life% = 1%-5%
notes:
- similar to schizophrenia
- NO PSYCHOTIC FEATURES FOR ALL DISORDERS
- no age of onset
- prevalence rate is pretty high
Cluster A:
1) Paranoid PD
Pervasive distrust and suspiciousness of others, as indicated by:
- Suspects others are exploiting, harming, or deceiving them
- Reads hidden demeaning or threatening meanings into benign remarks or events
- Perceives attacks on their character or reputation that are not apparent to others

- they believe other people are malicious motives ,do not trust them
- no delusions or hallucinations
- more common in men
Paranoid PD Causes and Treatments
etiological factors:
1) Genetics (linked with psychotic disorders): relative with schizo can have a slightly increase risk of paranoid PD
2) Childhood maltreatment
3) Very negative cognitive schemas: general lens of viewing the world very negatively
treatmet:
CBT to challenge assumptions and behaviours
- they are very unlikely to seek treatment, because they distrust people
- very difficult to form a therapeutic alliance
- treatment rarely works because they drop out
Cluster A:
2) Schizoid PD
Pervasive detachment from social relationships and a restricted range of interpersonal emotional expression, as indicated by:
- Neither desires nor enjoys close relationships
- Lacks close friends or confidants other than first-degree relatives

- they do not have social relationships and it always has been present
- they do not care about criticism or praise, they just do not care
Schizoid PD Causes & Treatments
Etiological factors
- Genetics (linked with psychotic disorders)
- Possible lower density of dopamine receptors
- Childhood abuse, neglect, shyness
Treatment

- Unusual perceptual experiences, including bodily illusions: bodily illusions: sensation that someone is beside them while laying down or that they are levitating
schizotypal PD contd
Odd thinking and speech
Odd/peculiar/eccentric behaviour or appearance
Excessive social anxiety that does not diminish, and is associated with paranoia
notes:
- speech can be very vague
- interesting hairstyles or clothing
- they may have that excessive social anxiety but linked to paranoia
- they lack friends, fewer friends are because of their paranoia or restrictive affect that they have
- still aware of their reality but have flares of schizophrenia (distant and aloof, but internally they do experience emotions)
- no delusions and hallucinations

schizotypal PD causes and treatments
Etiological factors

Treatment
- Antipsychotic medications show limited effectiveness
- comorbid with major depressive disorder
- Increase social skills
Cluster B
Defining characteristics
- Elevated impulsivity
- Dramatic, emotional, and erratic behaviours
Disorders
Antisocial PD : Life% = 1%-3%
Borderline PD: Life% = 1%-6%
Histrionic PD: Life% = 2%
Narcissistic PD: Life% = <1%-6%
Cluster B:
1) Antisocial PD
Pervasive disregard for and violation of the rights of others, as indicated by:
- Failure to conform to norms regarding lawful behaviour
- Impulsivity or failure to plan ahead
- Irritability and aggressiveness

Conduct disorder before age 15
Antisocial PD Controversy
psychopathy:
- Glibness/superficial charm
- Grandiose sense of self-worth
- Pathological lying
- Conning/manipulative
- Lack of empathy
notes:
psychopathy is a subset of antisocial PD
15-25% of people who have antisocial PD have psychopathy
Have more intelligent subtype?
Have much less empathy than antisocial pd
If have more intelligence they are more likely to go to jail
Plan out crimes more, so not that impulsive
Far less engaging in treatment
50-80% of male offenders have antisocial PD but only 15-25% have psychopathy
Cluster B
2) Borderline PD
Pervasive instability of relationships, self-image, and affects, as well as marked impulsivity, as indicated by:
- Frantic efforts to avoid real or imagined abandonment
- Impulsivity in two areas that are potentially self-damaging: driving fast / unprotected sex
- Chronic feelings of emptiness
Need 5/9 criteria to be diagnosed
Have pervasive instability of relationships, self-image, affects and impulsivity:
Frantic efforts to avoid real or imagined abandonment, leads to intense relationships, quick to put people on a pedestal, but any threat to them leaving them turns them to a villain
borderline PD causes
etiological factors
Genetic contribution tied to mood disorders
Early sexual or physical abuse
- have been abused or neglected in their life, 60-90% have this, people more abused are more likely to have suicide attempts, more often seen in women cause they experience more sexual abuse than men
Poor coping strategies
- risk behaviours, impulsivity
borderline PD contd
Recurrent suicidal behaviour, gestures, or threats, or self-mutilation
* 10% of BPD people attempt suicide and 6% die by suicide due to,
Affective instability due to reactivity of mood
- experience intense dysphoria (state of unease or dissatisfaction), apathy, irritability, anxiety
Inappropriate/intense anger, or difficulty controlling anger
- Substance abuse is very common
- Symptoms go away after 30 in some people
- More common in men than women
borderline PD treatments
they seek treatment for substance abuse usually or because family tells them
treatment
1) medications
- Tricyclics
- Lithium
- Atypical antipsychotics
2) dialectical behavioural therapy
Includes lots of interpersonal work, based on radical acceptance, accepting feelings while they are happening so they do not control them, distress tolerance is a huge component of DBT, emotion regulation
88% of people who do DBT receive remission from their symptoms within 10 years
borderline PD controversy
Comorbidity with mood disorders
24%-74% have MDD
4%-20% have bipolar disorders
Could borderline PD be a rapid-cycling subtype of bipolar disorder?
- could be a subtype but we are not very sure
- always validate their emotions and validate whatever they are saying
Cluster B
histrionic PD
Pervasive excessive emotionality and attention seeking, as indicated by:

- Uses physical appearance to draw attention
- Rapidly shifting and shallow expressions of emotions
notes:
Dramatic shifts of emotion, they may be super happy or super sad about something but may not feel that way
Easily influenced by others
Women diagnosed more than men, could be due to therapist bias
histrionic PD causes and treatments
1) Etiological factors
- Female form of antisocial PD?
- All-or-Nothing thinking
2) Treatment
- Examining interpersonal relationships
- Short-term gains vs. long-term costs

Female form of antisocial PD, it is all or nothing thinking - like simple life events are viewed as major life events
Not attention seeking but connection seeking
Short term gains vs long term costs

More common among men, about 75% of people diagnosed with NPD are men
narcissistic PD causes and treatments
1) etiological factors
Failure to develop empathy
Hypersensitivity to evaluation
- they do not like it when they are criticized
2) Treatment
Decreasing sense of grandiosity and hypersensitivity to evaluation
