1 Normal Personality Development and Personality s Learning Objectives Be able to describe the various personality disorders Be able to apply the personality disorder categories to patient scenarios Janet E. Johnson, MD, MPH Tulane University School of Medicine Department of Psychiatry and Behavioral Sciences Personality Defined as the totality of emotional and behavioral traits that characterize the person in day-to-day living under ordinary conditions. Usual manner of thinking, feeling, behaving and relating to others Relatively stable and predictable. Blend of inborn temperament, genetic strengths and vulnerabilities, and impact of positive and negative life experiences. Normal Personality Development Second half of 1 st year: attachment Internalization: mechanism for building psychological structure Stable pattern of a child s temperament becomes established during second year. Nature versus nurture? Behavioral genetics revealing pervasive genetic influences on normal and abnormal personality. What is Normal? Who s Normal? Who s to say? Circumstances, culture/sub-culture, setting/location, timing, age 1

2 Who s Normal? Personality assessment Meyers-Brigg Five Factor Model Cloninger s Seven-Factor Model Biogenic Spectrum Model Myers Brigg Questionnaire designed to measure psychological preferences in how people perceive the world and make decisions. Widely utilized Extrapolated from Jung s theories. Two pairs of cognitive functions: Rational functions: thinking and feeling Irrational functions: sensing and intuition Dichotomies Extraversion (E) (I) Introversion Sensing (S) (N) Intuition Thinking (T) (F) Feeling Judgment (J) (P) Perception 16 possible types Example: ESTJ Five Factor Model Neuroticism (anxiety, depression, vulnerability, hostility) Extraversion (warmth, assertiveness, activity, gregariousness) Openness (feelings, fantasy, ideas, values) Agreeableness (trust, altruism, modesty) Conscientiousness (dutifulness, selfdiscipline, deliberation) Seven-Factor Model of Temperament and Character Harm avoidance Reward dependence Novelty seeking Persistence Character factor Self-directedness Cooperativeness Self-transcendence 2

3 Temperament Factors (harm avoidance, reward dependence, novelty seeking, persistence Independently heritable Manifested early in life Involved in perceptual memory and habit formation Associated with biologic features Novelty seeking decreased dopaminergic activity Harm Avoidance -> high serotonergic activity Reward dependence low noradrenergic activity Personality s A personality disorder is a variant of those character traits that goes beyond the range found in most people. When personality traits are inflexible and maladaptive and cause either significant functional impairment or subjective distress they constitute a class of personality disorder. Patients with personality disorders show deeply ingrained, inflexible, and maladaptive patterns of relating to and perceiving both the environment and themselves General Diagnostic Criteria General Diagnostic Criteria An enduring pattern of inner experience and behavior that deviates markedly from the expectation of the individual s culture. The pattern is manifested in two or more of the following areas: Cognition (perceiving and interpreting self, other people and events) Affectivity (range, intensity, lability appropriateness of emotional response) Interpersonal functioning Impulse control The enduring pattern is inflexible and pervasive across a broad range of personal and social situations. The enduring pattern leads to clinically significant distress or impairment in social, occupational or other important areas of functioning. The pattern is stable and of long duration, and its onset can be traced back at least to adolescence or early adulthood. The enduring pattern is not better accounted for as a manifestation or consequence of another mental disorder. The enduring pattern is not due to the direct effects of a substance or a general medical condition. Personality s Personality s More likely to refuse psychiatric help than other psychiatric disorders Ego-syntonic Regarded as unmotivated for treatment Grouped into three clusters: A, B, C Other: Not otherwise specified and mixed Diagnosed on Axis II Elevated rates of divorce, unemployment, homelessness, perpetration of child abuse, child custody proceedings, separation Common in general population Prevalence of 10-18% Outpatient 30-50% Inpatient > 50% co-morbidity Males and females equal overall Etiology Genetics Psychoanalytic theories Freud: psychosexual development Reich: defense mechanisms 3

4 Common Defense Mechanisms Projection Splitting Regression Fantasy Dissociation Intellectualization Isolation Reaction formation Repression Acting out Passive aggression Cluster A: Paranoid, Schizoid, Schizotypal Odd, eccentric ( weird ) Key clinical features: social deficits, absence of close relationships Treatment: structure, rehabilitation, support, medication Course: stable Prognosis: poor Genetics: More common in the biological relatives of schizophrenic patients than among control groups. Paranoid Personality Paranoid Diagnostic Criteria Pervasive distrust and suspiciousness of others such that their motives are interpreted as malevolent, beginning by early adulthood and present in a variety of contexts, as indicated by four (or more) of the following: Suspects, without sufficient basis, that others are exploiting, harming, or deceiving him or her.
