Identify practical strategies for working with personality-disordered clients. 4. Recognize and learn to cope with countertransference. Copyright 2010, C. Barber, IBP Personality Style Consists of the ways in which a person relates to others, world, and self. Traits (internal tendencies – mostly inherited) Habits (behavioral tendencies – mostly learned) These may be adaptive or maladaptive, depending on the context. Copyright 2010, C. Barber, IBP Personality Disorder Enduring and pervasive pattern of perception, thought, and behavior Falls outside social/cultural norms Inflexible and maladaptive Causes impairment or distress Copyright 2010, C. Barber, IBP Disorder or Quirk? No clear line! Some people are just “eccentric.” Level of impairment/distress is usually the determining factor. Example: Grey Gardens Copyright 2010, C. Barber, IBP Models of Personality Pathology Categorical: DSM-IV-TR Dimensional: “Big Five” Prototypical: SWAP Copyright 2010, C. Barber, IBP DSM: A (Mostly) Categorical Model DSM-IV-TR Personality Disorders Cluster A Cluster B Cluster C Paranoid Antisocial Avoidant Schizoid Borderline Dependent Schizotypal Histrionic Obsessive-Compulsive Narcissistic Copyright 2010, C. Barber, IBP What makes DSM categorical? Well-defined criteria Cut-off scores indicate presence/ absence of disorder “Clusters” are based on common features Copyright 2010, C. Barber, IBP DSM: Pros Most widely used system Excellent tool for facilitating communication Easy to use Many categories match well-established clinical syndromes Copyright 2010, C. Barber, IBP DSM: Cons Possibility of multiple diagnoses Overlap in criteria Polythetic criteria set greater heterogeneity within diagnostic categories Cut-offs established by consensus (not empirically) “Reification” trap: Not all categories represent true constructs Copyright 2010, C. Barber, IBP Big Five: A Dimensional Model 5 higher-order personality dimensions Extraversion Agreeableness Conscientiousness Neuroticism/Emotional instability Openness to Experience 30 sub-dimensions Personality disorders are on a continuum with normal personality Copyright 2010, C. Barber, IBP Personality in Two Dimensions Neuroticism Introversion Extraversion Emotional Stability Copyright 2010, C. Barber, IBP Dimensional Model: Pros Empirically-based Dimensions appear to be heritable Provides more information Can be used to predict behavior Recognizes personality strengths (not just pathology) Copyright 2010, C. Barber, IBP Dimensional Model: Cons Can be unwieldy No clear cut-off for determining the presence of disorder Not user-friendly for clinicians who use DSM categories Copyright 2010, C. Barber, IBP SWAP: A Prototypical Model From Westen, Shedler, and Bradley, 2006 Descriptions of personality disorder “prototypes” (similar to DSM descriptions) Clinician rates the degree to which a patient matches the prototype Very good match – patient exemplifies diagnosis Good match – patient has diagnosis Significant match – patient has significant features Slight match – patient has minor features Little or no match – diagnosis does not apply Copyright 2010, C. Barber, IBP Coming (not so) soon to a bookstore near you: DSM-5! Expected to be published ca. 2013 “Best of both worlds”: Dimensional and Prototype models may be included Proposed “types” include antisocial/ psychopathic, avoidant, borderline, obsessive-compulsive, and schizotypal (all pending empirical validation) Copyright 2010, C. Barber, IBP Assessment Tools: Semi-structured Interviews Examples: SCID-II, SIDP-IV, DIB-R Pros: Very thorough Diagnoses generally map onto DSM constructs Highly reliable Cons: May require extensive training Validity is only as good as DSM construct validity Can take a long time to administer Copyright 2010, C. Barber, IBP Assessment Tools: Objective Personality Tests Examples: MMPI-2, PAI, MCMI-III Pros: Empirically-based Self-administered Well-studied Useful for describing and predicting behavior Cons: Not all objective measures provide diagnoses Can be complex to interpret Copyright 2010, C. Barber, IBP Assessment Tools: Projective Tests Examples: Rorschach, TAT, Projective drawings, sentence-completion tests Pros: Especially useful for psychodynamic work May tap unconscious processes Useful for testing defensive clients Cons: More subjective interpretation Do not provide a diagnosis Copyright 2010, C. Barber, IBP Caveats! Gather enough information: Don’t rely on a single encounter to tell you everything about a person’s personality. Don’t diagnose from afar: Beware of the “US Weekly” phenomenon. Not all difficult people have a personality disorder! Copyright 2010, C. Barber, IBP Caveats! Don’t rely on diagnosis alone—a label cannot capture the uniqueness and complexity of the individual. Bottom line on diagnosis and treatment: Try to identify, understand, and address problematic thoughts, emotions, behaviors, motivations, etc., rather than simply assigning a diagnosis. Copyright 2010, C. Barber, IBP A Few More Basics About PDs Community sample prevalence estimates range from 0.5-2.5% to 1015% (10-30% in clinical samples). PDs emerge in childhood/adolescence, but caution is used in diagnosing before 18 years of age. Considerable stigma still attaches to PDs. Copyright 2010, C. Barber, IBP A Few More Basics About PDs Treatment is challenging but not impossible. Treatment involves modification and management of patterns and tendencies, not “cure” of illness. Nature AND nurture appear to cause and contribute to PDs. Copyright 2010, C. Barber, IBP Theories of Personality Disorders Psychodynamic/ Psychoanalytic Theories: Developmental explanations Role of the unconscious Defense mechanisms Example: Object Relations Theory Copyright 2010, C. Barber, IBP Theories of Personality Disorders Cognitive-Behavioral Elements: Automatic thoughts Schemas Cognitive distortions Principles of reinforcement Observation and modeling Copyright 2010, C. Barber, IBP Theories of Personality Disorders Biological elements Everything we do has a biological basis! The brain responds to stimuli—it is constantly receiving and processing information. Both physical and environmental factors cause brain processes to go awry, leading to symptoms. Physical factors: Genetics, head injury, medical diseases Environmental factors: Learning history, trauma Copyright 2010, C. Barber, IBP Theories of Personality Disorders Biological elements Virtually all aspects of brain functioning are involved in personality. Examples: perception, memory, speech, executive functioning, social reasoning, etc. No single region is associated with any personality disorder. However, key regions include the prefrontal cortex and the limbic system. Copyright 2010, C. Barber, IBP Prefrontal Cortex From http://universe-review.ca/I10-80-prefrontal.jpg Executive functioning center Planning Decision making Behavioral activation Behavioral inhibition Reasoning Implementation of plans Copyright 2010, C. Barber, IBP Limbic System From http://www.geocities.com/hotsprings/3468/9/brain-limbic.jpg Cortical and subcortical structures that support and regulate: Emotion Long-term memory Autonomic functions Reward center Copyright 2010, C. Barber, IBP Brain – Behavior Links: Temporal Lobe Epilepsy (TLE) Most frequent form of partial epilepsy in adults. Characterized by abnormal electrical changes in temporal lobe, including amygdala. Emotional disturbances (e.g., fear, anxiety) are common after seizures. Some evidence suggests increase in obsessional traits in TLE. “Interictal” personality is controversial: Minimal evidence suggests a link between other proposed behaviors and epilepsy. Copyright 2010, C. Barber, IBP Brain – Behavior Links: Frontal Lobe Damage Damage to frontal lobes is often associated with disinhibition. Some individuals with frontal lobe damage display “acquired psychopathy.” However, deterioration of moral and social behavior is likely due to damage to other areas in addition to the frontal lobes (e.g., temporal lobes). Copyright 2010, C. Barber, IBP Neurotransmitters and Personality: Serotonin Regulation of mood and behavior Related to appetitive behaviors Low serotonin cravings for sweets and carbohydrates Implications for emotional eating and binge eating Copyright 2010, C. Barber, IBP Neurotransmitters and Personality: Norepinephrine Modulation of basic bodily processes and behavioral tendencies Plays a starring role in the “fight or flight” response (with its relative, epinephrine) Implicated in risk-taking behaviors Involved in the “rush” experience Copyright 2010, C. Barber, IBP Neurotransmitters and Personality: Dopamine Involved in pleasure-seeking and exploratory behaviors Appears to be related to brain’s natural opioids Highly reinforcing when released Also implicated in hallucinations and delusions Copyright 2010, C. Barber, IBP An Integrative Approach Characteristics and prevalence Defense mechanisms Object relational patterns Cognitive schemas Key biological mechanisms Copyright 2010, C. Barber, IBP Cluster A: Odd/Eccentric Paranoid Schizoid Schizotypal Copyright 2010, C. Barber, IBP Paranoid Personality Disorder 0.5-2.5% of general population. (*4.4%) Projection, projective identification, reaction formation. Others are dangerous or “users.” “I’m vulnerable.” More common in relatives with schizophrenia. Copyright 2010, C. Barber, IBP Schizoid Personality Disorder 1.7-4.9% of general population. (*3.1%) Withdrawal, intellectualization. The social world is engulfing. “I’m a misfit.” May be more prevalent in relatives of people with schizophrenia. Copyright 2010, C. Barber, IBP Schizotypal Personality Disorder 0.6-3.3% of the general population. Withdrawal, fantasy. Others are experienced as piecemeal and incoherent. “I am defective.” Dopamine (excess – psychotic symptoms; deficit – cognitive symptoms); ventricular enlargement. Copyright 2010, C. Barber, IBP Cluster B: Dramatic/Emotional Antisocial Borderline Histrionic Narcissistic Copyright 2010, C. Barber, IBP Antisocial Personality Disorder 0.7-1.0% of the general population. (*3.6%) Omnipotent control. Others are selfish, manipulative, and not worthy of respect. “I’m vulnerable.” Serotonin involved in impulse control and aggression; decreased autonomic arousal; overactive pleasure center. Copyright 2010, C. Barber, IBP Psychopathy, ASPD, and Criminality Psychopathy involves: Manipulation and deception Grandiosity Shallow emotions Lack of empathy and remorse Impulsive, irresponsible lifestyle Persistent violation of social norms and expectations People with ASPD may or may not be psychopaths. Many criminals don’t meet criteria for either. Copyright 2010, C. Barber, IBP Borderline Personality Disorder 0.7-1.6% of the general population. (*5%) Splitting, projective identification. Others are unpredictable and inconstant. “I’m defective.” “I’m vulnerable.” “I’m helpless.” “I’m bad.” Serotonin implicated in impulse control and emotion regulation. Differences in brain functioning (reduced response in anterior insula, which senses violation of social norms) less social cooperation/baseline trust. Copyright 2010, C. Barber, IBP Identifying At-risk Youths Developmental Psychopathology Oppositional defiant disorder Conduct disorder Non-suicidal self-injury Copyright 2010, C. Barber, IBP Histrionic Personality Disorder <1.0-2.0% of the general population. Repression, regression, conversion, sexualizing, acting out. Same-sex others are of little value; those of the opposite sex are powerful, exciting, “I’m nothing.” Biological mechanisms unknown. Copyright 2010, C. Barber, IBP Narcissistic Personality Disorder <1.0% of the general population. (*6%; M>F) Subtypes: Malignant/Oblivious, Fragile/Shy/ Hypervigilant Idealization, devaluation. Others are better than I am; I must be better than they are to feel good. “I’m inferior.” Biological mechanisms unknown. Copyright 2010, C. Barber, IBP Cluster C: Anxious/Avoidant Avoidant Dependent Obsessive-Compulsive Copyright 2010, C. Barber, IBP Avoidant Personality Disorder 5.0-5.2% of the general population. (*2.4%) Displacement, projection, rationalization, avoidance. Others who are more powerful can provide safety. “I’m undesirable.” Related to social phobia; dopamine deficits? Copyright 2010, C. Barber, IBP Dependent Personality Disorder 0.6-1.5% of the general population. Regression, reversal. Others are powerful and their care is essential. “I’m helpless.” Biological mechanisms unknown. Copyright 2010, C. Barber, IBP Obsessive-Compulsive Personality Disorder 2.0-2.4% of the general population. (*7.9%) Isolation of affect, reaction formation, moralizing, undoing. Others try to exert control, which must be resisted. “My world can go out of control.” Biological mechanisms unknown. Copyright 2010, C. Barber, IBP Other Problematic Styles Passive-Aggressive (Negativistic) Personality Deny negative emotions while acting them out in a covert or indirect way. Prevalence estimates unreliable (e.g., 20% of adolescents!) Projection, externalization, rationalization, denial. Others require conforming to their rules. “I should only have to do what I want; others’ needs are not as important.” Biological mechanisms unknown. Copyright 2010, C. Barber, IBP Other Problematic Styles Depressive Personality Self-criticism, judgment, intense guilt, dejection. Prevalence estimates unreliable. Introjection, reversal, idealization of others, devaluation of the self. Others will criticize, reject, or abandon. “I am fundamentally bad.” Biological mechanisms unknown. Copyright 2010, C. Barber, IBP Copyright 2010, C. Barber, IBP Common Co-Morbid Conditions Hypochondriasis Involves somatic/physical expression of emotions. Common in people with Histrionic, Dependent, Obsessive-Compulsive PD’s. Functions: obtain attention, keep others close, express emotions. Fears are not easily assuaged by “proof” of no illness. CBT appears to be an effective treatment. Interpersonal function of symptoms must also be addressed; expressive writing may also be helpful. Copyright 2010, C. Barber, IBP Common Co-Morbid Conditions Body Dysmorphic Disorder Involves severely distorted perceptions of one’s appearance Often comorbid with Borderline and Avoidant PD’s Treatment focuses on modifying distorted thoughts and preventing problematic responses. Plastic surgery is rarely effective. Psychopharmacology (especially SSRI’s) may be helpful. Copyright 2010, C. Barber, IBP Common Co-Morbid Conditions Eating Disorders Several diagnoses: anorexia nervosa, bulimia nervosa, binge-eating disorder. Borderline PD is a common diagnosis. Obsessive-compulsive PD may be involved in anorexia. CBT, DBT, family therapy can be helpful. Presence of PD greatly complicates treatment of eating disorders. Copyright 2010, C. Barber, IBP Common Co-Morbid Conditions Substance Abuse A large percentage of people with PD’s abuse substances. Especially common in Antisocial and Borderline PD’s. Presence of PD makes treatment significantly more difficult. Dual diagnosis-focused programs may be most appropriate. Interesting developments in psychopharmacology, e.g., cocaine vaccine. Copyright 2010, C. Barber, IBP Treatment Models Pharmacotherapy Schema Therapy (Young et al.) Mentalization-Based Therapy (Batement & Fonagy) Motivational Interviewing (Miller & Rollnick) Dialectical Behavior Therapy (Linehan) Many others! Copyright 2010, C. Barber, IBP Pharmacotherapy: Benefits Antidepressants Depression, anxiety Common for Clusters B, C Mood stabilizers Mood lability, aggression Common for Cluster B Antipsychotic agents Paranoia, illusions, odd beliefs Common for Clusters A, B Copyright 2010, C. Barber, IBP Pharmacotherapy: Drawbacks Insufficient for changing complex behavior patterns. Polypharmacy is common but carries greater risk. Potential for medication misuse is high.
