Personality Disorders



Personality Disorders

Carolyn R. Fallahi, Ph. D.

• High controversy surrounding the personality disorders.

• Problems with boundaries between various p.d. & their diagnostic criteria. Examples.

Theories of Personality

Psychodynamic Models:

• “Character pathologies”. Character = the ability to bring harmony to the tasks presented by the internal demands and by the external world.

• Freud’s explanation.

Behavioral Theories of Personality

• Watson & classical conditioning.

• Mid 1980s reinterpretations of traditional assessments – clinically applied behavioral approaches on Axis I.

• Recently … applying systematic approach to personality.

• Staats (19986): systematic approach & adds a behavioral & developmental dimension arguing that “basic behavioral repertoires” begin at birth and proceed hierarchically.

Interpersonal Models

• Personality = social product of interactions with significant others.

• Harry Stack Sullivan – father of interpersonal perspective. Reaction against the medical model & intrapsychic mode of Freud’s.

• Sullivan = pathology is created & perpetuated through maladaptive patterns of interactions between people.

Cognitive Models

• Very popular b/c most all clinical syndromes have cognitive elements.

• Example: Five-factor model.

• Aaron Beck: successful therapies for a wide range of Axis I diagnoses.

• Beck & Freeman (1990): cognitive theory of personality pathology. Dysfunctional and distorting schemas give rise to maladaptive interaction strategies which in turn trigger automatic thoughts and make the individual susceptible to repetitive and pervasive life difficulties.

Neurobiological & Temperament models

• Temperament = basic biological foundation of personality.

• Hippocrates 4th C B.C. – diseases stem from an excess of or imbalance of yellow bile, black bile, blood, & phlegm.

• 1920s Kretschmer – classification system based on thin, muscular, and obese types of physiques & linked them to psychopathology.

• Sheldon – ectomorphy, mesomorphy, and endomorphy.

• Cloninger (1987): interrelationship of 3 genetic neurobiological trait dispositions & associated them with a different NT system.

Schizoid & Avoidant Personality Disorders

• Similarity = interpersonal detachment.

• Schizoids appear emotionally bland & unresponsive & insensitive.

• Avoidants experience social interactions as aversive owing to their propensity for self=criticism.

• Distinction = motivation for the attachment. Schizoid lack the desire or ability to form social relationships; Avoidants desire interpersonal contact, but avoid out of fear of rejection & humiliation.

• Millon (1981) passive (schizoid) versus active (avoidant) detachment.

• Issue with the separation of these 2 disorders.

• Similar issues between schizoid & schizotypal p.d. Share interpersonal and affective features, especially social isolation & odd/inappropriate affect, similar to “negative” symptoms of Schizophrenia.

• Similar issues with avoidant and dependent p.d. Dependent p.d. = interpersonal submission, neediness, & fears of separation. Avoidant = shunts interpersonal intimacy, while dependent seeks it. Both = low self-esteem & lack of self-assertion.

• Other issues: Avoidant p.d. resembles social phobia.

• Symptoms of Schizoid p.d.

• Symptoms of Avoidant p.d.

• Issues with differential diagnosis.

• Case Study Example

• Comorbidity Issues: Avoidant & Schizotypal = 53%; 38% of schizotypals = schizoid; lesser degrees of comorbidity with paranoid, antisocial, borderline, passive-aggressive, dependent.

• Question: Are Schizoid & Avoidant discrete disorders? Overholser (1989) could not differentiate a sample on measures of anxiety, depression, psychosis, or introversion.

• Trull et al (1987) could distinguish avoidant p.d. on measures of anxiety, somatization, dysthymia.

• Issues with Avoidant & Dependent p.d.

• Trull et al (1987) symptoms highly correlated.

• Reich (1990) minor differences between avoidant & dependent on a variety of psychological tests.

• Schizoid & Avoidant also show comorbidity on Axis I disorders, especially social phobia. Herbert et al (1992) study found high correlation between avoidant p.d. & social phobia. Turner et al (1986) found social phobics have considerable distress & avoidance, but greater impairment found with avoidant p.d.

Historical Issues

• Eugene Bleuler (1924)

• Kretschmer (1925): anesthetic (e.g. insensitive) and hyperaesthetic (e.g. hypersensitive) = schizoid versus avoidant.

• Melanie Klein (1996): nurturing and depriving aspects of caregiving figure = splitting.

• Fairburn (1952) caregiver issues.

• Guntrip: schizoids are starved for love.

• Millon (1981) introduced avoidant p.d. Issues with this diagnosis.

Contemporary Views:

• Psychoanalytic

• Kernberg (1984)

• Torgersen (1985)

• Millon (1981)

• Kagan (1989)

• Stravyniski et al (1989)

Dependent and Histrionic Personality Disorder: they share at least one important feature = both are rooted in exaggerated, inflexible dependency needs.

• Different presentation styles

• HPD active, seductive stance

• DPD subservient, submissive stance

Dependent P. D.

• Bornstein (1992): 1. motivational, 2. cognitive, 3. affective, 4. behavioral.

Issues with the diagnosis of DPD:

• Symptoms vary by gender, ethnicity, age

• Men’s symptoms are more indirect & disguised

• Women more likely to talk about dependency needs

• Cultural differences

Epidemiology & Comorbidity:

• 47% outpatients; average 5-15%; general population 2-8%

• sex ratio no different according to DSM; research says something else.

• Comorbidity: eating disorders, anxiety, somatization disorders, depression?, schizoid p.d., avoidant p.d., schizotypal p.d., borderline & histrionic p.d.

Historically

• Neki (1976) cultural issues

• DSM no gender differences; many settings see more women.

• Comorbidity: anxiety, somatization, dissociative dxs, dysthmia. Also: antisocial, narcissistic, borderline, & dependent p.d.

Historical perspectives:

• Psychoanalytic: hysterical traits stem from Oedipal fixation.

• Marmar (1953) histrionic traits rooted in oral needs.

• Biosocial – Learning perspective: stimulation & affection.

• Sociable behaviors – impression of independence.

• Fear of autonomy & intense need for approval & attention.

Histrionic Personality Disorder

• Little agreement among clinicians & researchers

• Gregariousness, manipulativeness, low frustration tolerance, pseudo-hypersexuality, suggestibility, & somatizing tendencies.

• Women & Men – above average in physical attractiveness.

• Seductiveness – key.

• Gender differences.

• Cultural differences.

• 20th Century – hysteria split into 2 different viewpoints – sexual origins & immaturity/self-centeredness.

• DSM-III & IV: two broad categories have emerged.

• Contemporary Theories: psychoanalytical perspective.

• Marmor’s classic (1953).

• Research.

Obsessive-Compulsive Personality Disorder

• Similarities to Negativistic p.d. ( the old passive-aggressive p.d. lavel)

• Common themes include ambivalent & conflicted personality dynamics that underlie presentation.

• Ambivalence is defined as a lack of certainty over the source of reinforcement in one’s life.

• Ambivalent individuals = conflicted over whether they should follow what others want them to do or follow their own needs and wishes.

• “Anxious – fearful” cluster with anxiety & tension prominent symptoms.

• OCPD: extreme rigidity, preoccupation with details & perfectionism.

• Interpersonal relationships lacking – seen as cold, distant, & authoritarian. They have an excessive need to control others.

• The issue with subordinate relationships.

• Little motivation to become more flexible.

• OCPD: avoids unwelcome thoughts or impulses & frequently distracts them by becoming unduly critical and judgmental of others.

• Rigid, perfectionist, & restricted emotional expressivity.

• Millon: intense ambivalence as the central feature.

Prevalence

• 5-20% psychiatric patients

• Comorbidity: paranoid, histrionic, borderline, narcissistic, and avoidant p.d.

• Issues with OCD Axis I.

Historically

• Psychoanalytic theory: intense conflict during the anal stage of psychosexual development = “anal character”.

• Kraft-Ebing: “compulsion” = constricted thought processes in individuals with severe depression. Then began to use the term to indicate hidden emotions, incessant questioning, doubtfulness, & other characteristics.

• Anakastic (Schneider, 1923) = conceal feelings of insecurity, compensates by adopting an overly correct or scrupulous demeanor, & uses control in most relationships.

• Kretschmer = “sensitive” personality type.

• Mallinger (1984) parental rejection, authoritarian attitudes, & lack of respect for privacy.

• Salzman (1980) & Storr (1980) pervasive threat to security.

• Behaviorial: very little in the literature.

• Issues with the term OCPD.

• Turkat & Maistro (1985): learns maladaptive emotional reactions in home & emphasizes hard work & minimizes close interpersonal relationships.

• Cognitive Theory: Beck & Freeman (1990): OCPD clear distortions in thinking = produce rigidity & perfectionism.
