Lecture 10 - Personality Disorders Flashcards
What is personality?
A complex pattern of characteristics, largely outside of the person’s awareness.
–> Distinctive and stable patterns of perceiving, feeling, thinking, coping and behaving.
–> Emerges within biopsychosocial framework
What is a personality disorder?
An enduring pattern of deviant inner experiences and behaviours
–> Differ from cultural expectations. Is pervasive, inflexible, and stable
–> Leads to distress or impairment
*Often co-morbid to other psychiatric disorders
What are common features of personality disorders?
Cognitive Alterations
–> Altered interpretation of actions, relationships caused by maladaptive coping that results in dysfunctional ways of responding
Altered emotional stability
–> Alterations in person’s emotional arousal patterns which decreases one’s ability to accurately perceive one’s environment
Altered interpersonal functioning & self-identity
–> Identity may be disturbed or even absent
–> W/o adequately formed identity, an individual’s goal-directed behaviour is impaired and relationships are disrupted
Altered control of impulses - results in destructive behaviours
–> Inability to delay reactions and consider the consequences of their actions
With which three factors do we determine severity of a personality disorder?
Tenuous emotional stability
Interpersonal inflexibility
Tendency to become trapped
Tenuous emotional stability is a factor in determining severity of a personality disorder. What is meant by this?
Fragile personality patterns that lack resiliency under subjective stress.
Exaggerated emotions, unable to cope with normal stressful events.
Interpersonal inflexibility is a factor in determining severity of a personality disorder. What is meant by this?
People with healthy personality patters learn to be flexible in interactions with other people (relationships) and their environment.
People with unhealthy personality patters may not adapt effectively to interactions with others (doesn’t necessarily alter their social functioning)
Tendency to become trapped is a factor in determining severity of a personality disorder. What is meant by this?
Inflexibility generates and perpetuates dilemmas.
Exaggerated emotional reaction, followed by an impulsive action may lead to an unwanted sequence of events.
What are the cluster A personality disorders?
Paranoid, schizoid, schizotypical
What are the cluster B personality disorders?
Borderline, antisocial, histrionic, narcissistic
What are the cluster C personality disorders?
Avoidant, dependent, OC
What are the features of paranoid personality disorder?
How do they interpret intentions and how is their insight?
Mistrustful, avoid relationships that cannot control (prefers solitude, avoids intimacy, secretive).
Incidents are often misinterpreted as having sinister or hidden meaning.
Tend to lack insight into their behaviours and may be hypercritical and attribute these traits to others (projection).
What is the etiology of paranoid personality disorder?
Possible genetic link
–> relatives of persons with schizophrenia
–> persons with paranoid personality disorder may have been the source of parental conflicts and victims of some sort of harassment (due to odd behaviours)
How can we treat paranoid personality disorder?
Psychotherapy
–> focused on developing trust in relationships
Role play
–> may be initially perceived as threatening
Reality checks
Pharmacotherapy: as needed for symptom management of anxiety and sporadic delusions
What nursing assessment and interventions are helpful for paranoid personality disorders?
Nurse -Client relationship may be challenging to establish
Use straight forward communication - being to friendly or joyful can be perceived as joyful
–> Setting boundaries
–> Use of acceptance, reflection, confrontation
Goal is to assess problematic areas, gain another view of the situation and gently confront through reality checks and use of unhealthy coping mechanisms
What are features of schizoid personality disorder?
How are their social relationships?
Expressively impassive (unable to experience the pleasurable aspects of life), indecisive and interpersonally unengaged.
Blunted or flat affect.
Introverted, reclusive and heightened anxiety when engaging in social activities.
Often incapable of forming social relationships or react appropriately (emotionally) to others.
Rejection of intimacy.
–> If friendship or intimacy is established = delusional content may be divulged (e.g., imaginary friends)
Depersonalization and detachment –> life observers, not participants
What is the etiology of schizoid personality disorder?
Unexplained role of heredity
–> w schizophrenia and schizotypal personality disorder
Associated with detachment and neglect during childhood
–> Alone in school and have poor academic results
How can we treat schizoid personality disorder?
Psychotherapy
–> Individual and group to improve interpersonal relationships
Pharmacotherapy
–> Antidepressants for impassivity
–> Antipsychotics to improve expressiveness
What is the goal of care with schizoid personality disorder?
Enhance the pleasure and increase emotional responsiveness to others
What nursing assessments and interventions should be used for schizoid personality disorder?
Assessments:
MSE aimed at identifying symptoms such as delusions with goal to address fears in order to increase pleasure
Interventions:
Do not encourage social interactions, work only on anxiety and coping
Have realistic expected outcomes to increase the pt’s satisfaction with solitary activities
Milieu therapy to protect the patient against being ridiculed/intimidated.
What are features of schizotypal personality disorder?
Eccentric
–> without attaining the level of decompensated schizophrenia.
Pattern of social and interpersonal deficits
–> no close friends – seeks solitude.
Cognitive and perceptual distortions
–> magical thinking, ideas of reference, illusions, bizarre communication – paranoia (people out to get them)
Constricted and inadequate affect.
Difference with schizophrenia: these people can be made aware of their perceptual disturbances.
What is the difference between type A PDs and schizophrenia?
PDs tend to remain stable throughout the person’s life (including childhood)
Schizophrenia is dynamic and evolves, with cognitive decline that is not present in PDs.
Level of behaviour “oddness” - schizoid - schizotypal - schizophrenia
What is the etiology of schizotypal personality disorder?
First degree relatives with schizophrenia
Brain abnormalities consistent with those with schizophrenia
What treatment is used for schizotypal personality disorder?
psychotherapy
–> Interpersonal and group for interpersonal relationships
Pharmacotherapy
–> Low dose antipsychotics to help with positive symptoms and improve day-to-day function
What assessments and interventions can be helpful for those with schizotypal personality disorder?
Assessment:
MSE focus on addressing symptoms requiring immediate action such as command hallucinations, thoughts of self harm/suicide, and delusions that might put themselves of others in danger
Intervention:
Similar to management of schizophrenia
–> Respect of person’s need for solitude
Respect and be aware the bizarre beliefs or associations with groups and cults may be an integral part of a person’s life
–> May be source of interpersonal satisfaction out of these groups
What are the features of BPD?
Instability of interpersonal relationships
–> fear of abandonment, unstable self-image, emotions, identity
Ambivalence
–> from solitude to need for intense social support
–> from idealization of others to intense devaluing
When personal expectations are not met: intense shame, self-hate and self directed anger
–> substance use, frequent self-harm and suicide attempts (in periods of dissociation) – possible psychotic episodes.
Intense and lability in affect
–> frequent depression and anxiety, anger, feeling of emptiness (feeling numb), emotional manipulation, impulsivity, splitting, self-centeredness.
–> Impulsivity
Dichotomous thinking, projective identification (blame others for what happens to them).
