Personality Disorder II Flashcards
Antisocial PD Assumption and Causes
- Assumption: People act in a rational manner guided by logic, rules & social convention/mores
- So why does a subgroup of individuals engage in repeated behaviours that are:
- Carried out with scant regard for consequences
- Reflect an inability to delay gratification
- Apparently self-defeating (cause harm to themselves or to others)
- Irrational in that aversive outcomes outweigh reward?
Aetiology of Antisocial PD
Constitutional Factors
- Causes not fully understood
-
Constitutional factors (neurobiological correlates) establishes predisposition with expression of antisocial variant determined by environmental & familial influences
- Externalising vulnerabilities: heritable broad trait-dispositional factor reflecting disinhibitory personality & risk-taking found in childhood conduct disorders, adult antisocial behaviour, and substance-use disorders
Aetiology of Antisocial PD
Biological Factors
- Reduced levels of serotonin (impulsive behaviours)
- Low resting heart rate >> physiological hypo-arousal >> sensation seeking
- Neuropsychological deficits on frontal lobe executive functioning
- Weak behavioural inhibition & emotional reactivity (less responsive to threat & punishment)
- Evolutionary advantage(?)
Aetiology of Antisocial PD
Psychosocial Factors
- Personality & temperament, shaped by environment & learned coping skills to deal with stress
- Social factors: childhood dysfunctional role modelling & interactions with family
- Peer group interactions: deviant sub-cultures - cause or effect?
Antisocial PD: Treatment
- Literature reviews indicate inherent difficulties and ineffectiveness of psychological interventions (e.g., CBT, psychotherapy)
- Pharmacological agents to reduce aggressive impulsivity (lithium, serotonin selective reuptake inhibitors)
- Multifaceted interventions targeting impulsivity, aggression, addictive urges, and narcissistic traits required BUT outcomes not positive, particularly for the severe end of the spectrum (psychopathy)
Aetiology of Borderline PD
Genetic Factors
Brain structure
- Threatening/aversive stimuli activate amygdala >> anterior cingulate >> prefrontal cortices
- Anterior cingulate: cognitive evaluation/processing of mood & affect regulation (implicated in response to conflicts)
- Prefrontal cortex: inhibition of impulsive aggression by regulating amygdala
Brain chemistry
- Serotonin regulates impulses, aggression & affect: linked to emotional instability, suicidal behaviours & impulsivity behaviours
- Low levels of serotonin impair control of destructive urges
Aetiology of Borderline PD
Childhood complex traumas
- Emotional/sexual/physical childhood abuse implicated in aetiology >> developmental arrest
- BUT abuse alone neither necessary/sufficient
- Child-parent relationship mediating factors (unstable, non-nurturing, lack of parental empathy & invalidation of experiences) hinders/distorts development of secure attachments >> emotion dysregulation
- Exacerbated if family member is perpetrator
- Attachment theory: infants construct internalised concepts of self & others based on experiences
- Sense of security & self-worth enhanced by family members shapes personality traits
- Parental failure to teach child to label & regulate emotional arousal, tolerate emotional distress, and when to trust own emotional responses during distress
- In adulthood, individuals invalidate their own emotional experiences & depend on others for accurate reflections of external reality
Primary characteristics manifestations of BPD psychopathology
- Emotional dysregulation
- Behavioural dysregulation
- Interpersonal dysfunction
What does BPD treatment target?
IMPULSIVE
- Impulsive
- Moodiness
- Paranoia under stress
- Unstable self-image
- Labile & intense relationships
- Suicidality
- Inappropriate anger
- Vulnerability to abandonment
- Emptiness (sense of identity)
Dialectical behaviour Therapy (DBT) for BPD
- Developed for Borderline PD by Marsha Lineham (1993)
- CBT-based intervention for chronically suicidal behaviours
- A bio-psycho-social model that builds on / modifies traditional behavioural approaches
Goals of DBT
- CHANGING behaviours causing suffering whilst simultaneously
- ACCEPTING oneself and current situation/life circumstances
- to enhance behavioural, emotional thinking & interpersonal interactions
4 modules of DBT
Each containing coping skills used to achieve specific goals:
- ACCEPTANCE skills
- Mindfulness
- Distress tolerance
- CHANGE skills
- Interpersonal effectiveness
- Emotion regulation
DBT Mindfulness
- Observing/attending to events, emotions & behavioural responses even if distressing
- step back & allow experience with awareness rather than leave or terminate emotions
- Learning to apply verbal labels to behaviours and environmental events
- overcome tendency for literal reflection – “I feel unloved” interpreted literally as “I am unloved”
- Participating with attention as opposed to mindlessly engage in an activity
DBT Distress tolerance
- Assumes ability to tolerate and accept distress is essential for mental health
- Skill is to accept non-judgmentally current situation
- Experience current emotional state without attempt to change it
- Observe own thoughts & actions without controlling or stopping these
- Acceptance of reality does not mean approval of reality
- distress is accepted but does not mean that it is not nevertheless still painful
DBT Emotion regulation skills
- Difficulties in regulating pain emotions are central to behavioural reactions
- Assumption is that emotional distress is a secondary response to intense shame, anxiety or rage
- Skills in identifying and labelling affect. Observe & describe:
- Event triggering emotion
- Interpretation of event
- Phenomenonological experience (physical & emotional feelings)
- Behaviours associated with emotions
- After effects on functioning
DBT Interpersonal effectiveness
- Skills in specific interpersonal problem-solving, social & assertiveness skills to modify aversive environments & develop effective relationships
- how to ask for things and say ‘no’ to other people, while maintaining self-respect and important relationships.
- Limit setting on demanding behaviours => need for reassurance and acceptance
The role of schemas in BPD
- Long-standing self-defeating patterns/themes in thinking, feeling & behaving/coping (life-traps) e.g., “I’m unlovable”, “I’m a failure”
- Broad, pervasive dysfunctional themes developed during childhood developmental phase and persisting into adulthood
- Composed of memories, emotions, & cognitions defining perspective of self and relationship with others that result in significant degrees of impaired functioning
Schema-focused therapy for BPD
- Integrative approach to treatment, combining aspects of cognitive-behavioral, experiential, interpersonal and psychoanalytic therapies into one unified model (Young, 1990; 1999)
- Three stages:
- Assessment: schemas are identified (use of questionnaires)
- Emotional awareness & experiential phase: identifying how schemas operate in day-to-day living
- Behavioral change: replacement of negative, habitual thoughts & behaviours with new, healthy cognitive and
- behavioral options
18 schemas elicited in Schema Questionnaire
- Abandonment
- Mistrust
- Emotional Deprivation
- Defectiveness
- Social Isolation
- Dependence
- Vulnerability to Harm
- Enmeshment
- Failure to achieve
- Entitlement
- Insufficient self-control
- Negativism
- Self-punitiveness
- Emotional inhibition
- Unrelenting standards
- Subjugation
- Self-sacrifice
- Approval seeking
Schema therapy: Modes
- MODE: consists of current mood state, behaviours & cognitions (exist along a continuum of dissociation)
- Innate Child Modes: Vulnerable / Angry / Impulsive / Contented child
- Maladaptive Parent Modes: Punitive / Demanding / Critical parent
- Healthy Adult Mode
- Task for therapist & patient: to track the rapid shifts among modes
Schema perpetuation
- Tendency for schemas to be strengthened over time
- Schemas influence information processing such that the individual selectively perceives and interprets information so as to
- confirm maladaptive schemas
- AND filters out disconfirming information
Schema theory: Coping styles
- Personality trait
- While making life more manageable in the short term, serve ultimately to reinforce the schema
-
‘schema surrender’: the individual accepting the truth of the schema and behaving in consistent ways
- e.g. choosing an abusive partner in the case of someone with a mistrust/abuse schema
-
‘schema avoidance’: blocking features of the schema (such as the associated thoughts, images or feelings) OR avoiding situations that trigger the schema because of the distressing nature of the schema content
- e.g. substance misuse OR avoiding relationships in someone with an abandonment schema
-
‘schema overcompensation’: reacting against the schema by embodying its polar opposite
- e.g. for someone with a defective schema overcompensation might include arrogance >> problem not recognised AND risk of confirming schema because of interpersonal consequences (alienation and rejection by others)
Beck’s cognitive model for treating general PDs
- Relies on 2 key premises
- Each PD is thought to be characterised by specific maladaptive core beliefs
- These beliefs influence the processing of social information in such a way that maintains the person’s dysfunctional beliefs
- Filtering out inconsistent information
- Interpreting ambiguous information as consistent with dysfunctional belief
CBT for PDs
-
Cognitive case formulation
- drawing together theory, research and the client’s experiences in order to explain the causal and maintaining factors relating to their problems
-
Cognitive restructuring
- identifying and challenging dysfunctional cognitions that give rise to negative feelings and behaviours
-
Supporting behavioural change
- using strategies such as learning the skills of problem-solving to decrease unhelpful behaviours and increase adaptive solutions to problems
