Q

What are Personality Disorders?

A

A group of disorders marked by persistent, inflexible, maladaptive patterns of thought and behaviour that develop in adolescence or early adulthood and significantly impair an individual’s ability to function

2
Q

What are the characteristics of a personality disorder?

A

 Enduring pattern of behaviour that deviates markedly from expectations within the culture Associated with unusual ways of interpreting events, unpredictable mood swings or impulsive behaviour Result in impairments in social and occupational functioning Represent stable patterns of behaviour that can be traced back to adolescence or early childhood Previously characterized as Axis II disorders because they represent long-standing, pervasive and inflexible patterns of behaviour

3
Q

What are the primary clusters of personality disorders?

A

 DSM-IV-TR (APA, 2000) organised personality disorders into three clusters: Odd/Eccentric Personality Disorders Dramatic/Emotional Personality Disorders Anxious/Fearful Personality Disorders

4

7
Q

What are some conceptual issues with personality disorders?

A

 Personality Disorders may not be discrete disorders but represent extremes of normal personality (Costa & McRae, 1990) Many of the characteristics of different personality disorders overlap (e.g. impulsivity)

8
Q

What are the characteristics of anti social personality disorder?

A

 The term sociopath or psychopath is sometimes used to describe this personality type APD is now defined mainly in terms of violations of social norms Is highly associated with criminal and violent behaviour Prison populations have between 50-70% of inmates diagnosable with APD (Fazel & Danesh, 2002)

9
Q

What are the characteristics of borderline personality disorder?

A

 Features an enduring pattern of instability in personal relationships and lack of well-defined self-image Fear of abandonment is a central feature which leads to conflict-ridden relationships Associated with regular mood swings and aggressive behaviour Highly comorbid with Axis I disorders such as depression and anxiety disorders

10
Q

What Is ‘Disordered’ About Personality Disorders

A

 People with personality disorders are often referred for treatment because of the consequences of their behaviour: Some are unable to form lasting, close relationships Many often develop comorbid Axis I disorders Their behavioural style may be a risk to themselves or others Many behavioural styles interfere with an individual’s ability to achieve in occupational or educational spheres

11
Q

Gender Differences in Personality Disorders

A

 75% of individuals diagnosed with Borderline Personality Disorder are female (Widiger & Trull, 1993) Risk of avoidant, dependent and paranoid personality disorder is also greater in women

12
Q

Cultural Differences in Personality Disorders

A

 Little evidence to suggest that the prevalence of personality disorders differs across cultures There may be some ethnic differences – BPD is higher in Hispanic than Caucasian & African Americans (Grant et al., 2004)

13
Q

THE AETIOLOGY OF PERSONALITY DISORDERS

A

 Because most symptoms of personality disorders differ, there will be no over-arching theory of causation personality disorders One characteristic that is common to all is that their behaviour patterns are enduring, suggesting that inherited or developmental factors are important

14
Q

Cluster B: Antisocial Personality Disorder

A

 Because APD is closely related to criminal and antisocial behaviour attempts have been made to: Identify childhood behaviours that may predict later adult APD Identify the developmental factors that cause APD Ascertain whether there is an inherited component to APD Identify any biological or psychological processes that may be involved in APD

15
Q

Childhood & Adolescent Behavioural Precursors of APD

A

 The best predictor of APD is a diagnosis of conduct disorder during childhood Adolescent smoking, alcohol use, illicit drug use, police trouble and sexual intercourse before 15-years are strong predictors of APD Some theorists also suggest that ADHD is a predictor of APD (but see next slide)

16
Q

Developmental Factors - APD

A

 Antisocial behaviour may be learnt from parents (Paris, 2001) Parents may reinforce antisocial behaviour (Capaldi & Patterson, 1994) Lack of parental love may nurture antisocial behaviour (Gabbard, 1990) Inconsistent parenting may be important during the development of APD (Marshall & Cooke, 1999)

17
Q

Genetic Factors – APD

A

 APD appears to run in families Twin studies suggest higher concordance rates in MZ than DZ twins (Lyons et al., 1995) Incidence of APD in an adopted child is better predicted by APD in the biological than adopted mother (Ge et al., 1996)

18
Q

Cognitive Models - APD

A

 Individuals with APD may possess dysfunctional schemas that determine their antisocial reactions (Young et al., 2003) When responding to important events, individuals with APD may switch quickly and unpredictably between schemas to make their behaviour seem erratic (Horowtiz et al., 2001)

19
Q

Physiological & Neurological Factors – APD

A

 Individuals with APD exhibit physiological characteristics that may explain their APD: Have significantly lower levels of anxiety and lower levels of physiological reactivity Respond to emotional stimuli with slow autonomic arousal and low levels of EEG activity Frequently fail to exhibit fear learning in aversive classical conditioning procedures (Lykken, 1995)

20
Q

Risk Factors for BPD

A

 A history of difficulties in childhood, including childhood physical, verbal and sexual abuse, childhood neglect or rejection, inconsistent or loveless parenting, and inappropriate parental behaviour (e.g. substance misuse or sexual promiscuity) Academic underachievement, low intelligence and poor artistic skills

21
Q

Biological Theories of BPD

A

 Evidence for a genetic component (twin studies indicate concordance rates of 35% and 7% for MZ and DZ twins respectively) (Torgersen et al., 2000) 44% of individuals with BPD belong to a broader bipolar disorder spectrum Individuals with BPD have a number of brain abnormalities e.g. dysfunctions in brain dopamine  Neuro-imaging techniques reveal abnormalities in a number of brain areas

22
Q

Psychological Theories of BPD

A

 Object Relations Theory argues that individuals with BPD have received inadequate support and love from important others, resulting in an insecure ego which is likely to lead to lack of self-esteem and fear of rejection. Splitting A defence mechanisms in which aspects of others which are evaluated in a polarised fashion. As with APD, individuals with BDP may acquire a set of dysfunctional schemas that maintain their erratic and emotional behaviour (Young et al., 2003)

23
Q

Dialectical Behaviour Therapy (DBT)

A

 Developed in the 1990s by Marsha Linehan, particularly for the treatment of BPD Based on a biosocial theory of BPD (Linehan, 1993, cited in Palmer, 2002) Dialectical refers to contrasting views or positions taken by the client Emphasis on integrating opposing behaviours & on interconnectedness Brings together aspects of CBT and principles of Zen Buddhism e.g. acceptance Aims to foster the development of emotional regulation & tackle areas of skills deficit Linehan published Cognitive Behaviour Treatment of Borderline Personality Disorder in 1993 Outpatient delivery Intervention lasts around one year Individual sessions, group skills training sessions and telephone support, plus weekly consultation group 4 modules  Emotion regulation, mindfulness, distress tolerance, interpersonal effectiveness

24
Q

Schema Therapy

A

 Developed by Young, Klosko & Weishaar (2003) Schema theory outlines three specific stages: Clients need to be convinced that their maladaptive schemas are actually a cause of their symptoms Attempts to identify and prevent schema avoidance responses Examination of the life events that have given rise to maladaptive schemas

25
Q

Schema Domains & Early Maladaptive Schemas

A

 Disconnection & Rejection Mistrust/abuse  Abandonment/instability Defectiveness/shame Emotional deprivation Social isolation/alienation Impaired Autonomy & Performance Failure Dependence/incompetence Enmeshment/undeveloped self Vulnerability to harm or illness

26
Q

Schema Domains & EMSs

A

 Impaired Limits Entitlement/grandiosity Insufficient self-control/self-discipline Other-Directedness Subjugation  Self-sacrifice Approval seeking Overvigilance & Inhibition Punitiveness Emotional inhibition Negativity/pessimism Unrelenting standards

27
Q

Schema Responses/Coping Styles

A

 Avoidance Overcompensation Surrender
