Borderline Personality Disorder Cluster C: Anxious; Fearful Avoidant Personality Disorder Dependent Personality Disorder Obsessive-Compulsive Personality Disorder FEATURES OF PERSONALITY DISORDERS Early onset Evident at least since late adolescence Stability No significant period when not evident Pervasive Evident across a wide range of personal, social, and occupational situations Clinically significant maladaptive behavior Personal distress or impairment in social and occupational functioning Etiology The cause of personality disorders is unknown Some links we’ll be given here ODD OR ECCENTRIC BEHAVIOR Paranoid personality disorder Schizoid personality disorder Schizotypal personality disorder Paranoid Personality Disorder Diagnosis Paranoid personality disorder is characterized by a pervasive distrust of others and a constant suspicion that people around you have sinister motives Onset and Prevalence Usually begins by early adulthood and present in a variety of contexts Males: 3.5% Females: 2% Complications Since these individuals often keep to themselves and rarely become intimate with others, their unusual ideas often remain unnoticed They rarely seek clinical help Etiology Unknown Genetic link: Incidence appears increased in families with a schizophrenia patient Treatment Treatment of paranoid personality disorder can be very effective in controlling the paranoia but is difficult because the person may be suspicious of the doctor Medications for paranoid personality disorder are generally not encouraged, as they may contribute to a heightened sense of suspicion that can ultimately lead to patient withdrawal from therapy Prognosis Poor Without treatment this disorder will be chronic Long-term psychoanalysis can lead to some improvement Schizoid Personality Disorder People with schizoid personality disorder avoid relationships and do not show much emotion They genuinely prefer to be alone and do not secretly wish for popularity They tend to seek jobs that require little social contact Withdrawn and reclusive Their social skills are often weak and they do not show a need for attention or acceptance They are perceived as humorless and distant and often are termed "loners Onset and Prevalence Late adolescence to early adulthood Approximately 2% of total population with slight gender difference (M > F) Etiology Genetic link to schizophrenia Treatment People with the disorder rarely seek treatment Treatment can be difficult because of initial reduced capacity or desire to form a relationship with a health professional Medications are not effective Prognosis Poor Survey results of psychologists: About 75% felt either they couldn’t provide therapy/untreatable or felt that patients wouldn’t follow treatment recommendations Schizotypal Personality Disorder The disorder is characterized by odd forms of thinking, perceiving, and communicating Individuals with this disorder often seek isolation from others They sometimes believe they have extra sensory or magical abilities They generally engage in eccentric behavior and have difficulty concentrating for long periods of time Their speech is often over elaborate and difficult to follow Individuals with this disorder often seek isolation from others Onset and Prevalence Usual onset is in early adulthood About 3% of general population Slightly M > F Increased prevalence among relatives of people with schizophrenia Complications 30-50% also have major depressive disorder Some may develop schizophrenia Eating disorders are not uncommon with schizotypal Etiology Genetic link to schizophrenia Treatments Behavioral Social skills training Accept/adjust to solitary life style Physiological Some improvement with Haldol Many stop due to side effects Prognosis Poor Relatively stable Very small proportion will go on to develop schizophrenia or another psychotic disorder Dramatic or Emotional Personality Disorders Antisocial Personality Disorder Histrionic Personality Disorder Narcissistic Personality Disorder Borderline Personality Disorder Antisocial Personality Disorder Terminology Psychopath; Sociopath; Antisocial Personality Disorder Probably a universal disorder Sex Difference: 3% males Less than 1% females Occurs about equally in all ethnic groups, cultures, historical periods Most research with criminals, but it may occur in non-forensic populations Clinical Description of the Psychopath Egocentric, arrogant, deceitful, shallow, impulsive individuals who callously use and manipulate others with very little or no sense of shame, guilt, remorse Often violent Unguided by dictates of "conscience" Lack of empathy; only an abstract, intellectual awareness of others feelings No loyalty to any person, group, code, organization, or philosophy; self-interest Clinical Description of the Psychopath Human predators Look for places where there is opportunity for easy money, power, control, prestige Others exist only as emotional, psychical, and financial prey with no rights of their own Prey on the vulnerable Psychopathy is associated with pleasure and thrill-seeking behavior Ted Bundy: The classic example Physiological Explanations Brain activity Deficient Arousal Activity Genetic Influence Relative immunity to stimulation Stressful situations are nothing to them Psychologists are unsure Neurochemistry Low levels of serotonin Behavioral Explanations Family Relationships Early parental loss Parental rejection Childhood history of conduct disorder Treatments • Intensive individual psychotherapy or cognitive behavioral therapy is used • Try to get patient to develop a sense of trust • Usually doesn’t happen • Group psychotherapy • Try to get patient to develop a sense of trust • Usually doesn’t happen • Medications are not effective Prognosis Poor No treatments are effective Usually a lifetime disorder Histrionic Personality Disorder These people show a pattern of emotionality and attention-seeking Begins in early adulthood Use physical appearance to draw attention to oneself The cause of this disorder is unknown, but learned and inherited characteristics may play a role Gender difference: F>M Etiology Behavioral link: There has been evidence and research clearly indicating past history of sexual abuse and/or being alienated by parents as a child This alienation usually takes the form of emotional alienation, and that love is really not there for them These children grow up seeking and desperately needing attention at all costs Treatments Long-Term Psychotherapy These individuals do not want to address or deal with their issues because their issues have provided them some secondary gain It is very difficult to stop maladaptive behavior when it does reward or give the individual something back Medication is generally not prescribed and is of minimal benefit Prognosis Poor Treatment is very difficult Confrontation in therapy is not unusual A high rate of these individuals will drop out of therapy Narcissistic Personality Disorder A disorder of the personality characterized by selfcenteredness, being self-absorbed, and an inability to empathize with the effects of one’s behavior on others This disorder usually begins by early adulthood Gender difference: M>F The cause of this disorder is unknown Etiology Unknown At present there are two major theories about the origin and nature of NPD Neglectful parents (behavioral) The other regards it as a young child's defense against psychological pain (psychodynamic) Treatments Long-term Psychotherapy Individual Group therapy Goal here is to achieve empathy Therapist should be less authoritative in these sessions but address a patients grandiosity in next individual setting Note: Drug treatments not effective Prognosis Very slow process Borderline Personality Disorder An individual trait that reflects ingrained, inflexible, and maladaptive patterns of behavior characterized by impulsive and unpredictable actions, mood instability, and unstable interpersonal relationships They view themselves as victims of circumstances and take little responsibility for themselves or for their problems The person with a borderline personality is impulsive in areas that have a potential for selfdestruction Prevalence Officially recognized as a diagnosis in 1980 Estimated to occur in 3%-5% of the general population Tends to occur more often in women Some research indicates twice as often Defining Characteristic… Instability Interpersonal relationships Very stormy and that’s putting it mildly Emotionally Major mood shifts Identity Endless search for self Behaviorally Unstable in every way Thought processes Unusual perceptions Symptoms Kernberg (1975) They view the whole world as "all good" or "all bad“ All people, all experiences, and their self are viewed in extremes They cannot grasp the concepts of moderation or something being "all right", OK, average, or ordinary Causes The exact cause of borderline personality disorder is not known However, several psychological hypotheses rely on biological, social, and psychological factors to understand people with this disorder Behavioral Explanations Attachment experiences in early childhood Parent or parent’s not paying enough attention to the child’s feelings Parental abuse (sexual and physical) Divorce Alcoholism Physiological Explanation Need more research here but it seems there is too much brain activity with these individuals Dopamine levels too high Psychodynamic Treatments These therapists try “face to face” psychotherapy three times a week continually ranging over several years Emphasis on present behavior in beginning of sessions rather than childhood experiences Be careful of transference Cognitive-Behavioral Treatment Dialectical Behavior Therapy See handout Drug Therapy Make use of various types of medication… Mood stabilizers such as lithium Antidepressants Low-dose neuroleptics These drugs reduce brain activity Reduce dopamine levels Medication is mildly effective by itself Prognosis Poor outcome… Tend to remain the same over time Borderline’s with high socioeconomic status along with intensive treatment tend to improve in their interpersonal relationships Most will attempt suicide 8%-10% will commit suicide Alcohol abuse is high among those with borderline personality disorders Anxious or Fearful Disorders Personality disorders characterized by anxious or fearful behaviors… Avoidant Personality Disorder Dependent Personality Disorder Obsessive-Compulsive Personality Disorder Avoidant Personality Disorder Avoidant personality disorder (APD) is considered to be an active-detached personality pattern Relatively new disorder having been added to DSM in 1980 Avoidants purposefully avoid people due to fears of humiliation & rejection They usually have low self-esteem The usual onset for APD is early adulthood Less than 1% of general population No gender difference Characteristics Speechlessness Becoming quiet can be one sign of fear When they do speak, avoidants may use frequent pauses & speak slowly Over talkative In rarer cases sometimes they are so fearful they can’t stop talking Characteristics Interpersonal Conduct Avoidants often test others to determine whether or not they are being sincere in their friendliness Because they may frequently see rejection where it does not exist, people will tend to fail these tests & then later be avoided Characteristics Cognitive Style: Hypervigilance Avoidants excessively monitor the situation to the extent that they are trying to process so much information, they are no longer paying sufficient attention to the interaction itself Affective Expression People with APD may exhibit little affect due to the fear that showing their emotions will make them vulnerable to rejection or humiliation To observers, avoidants may appear tense & anxious Etiology Unknown Behavioral link: Many persons diagnosed with avoidant personality disorder have had painful early experiences of chronic parental criticism and rejection Treatment The general goal of treatment in avoidant personality disorder is improvement of selfesteem and confidence As the patient's self-confidence and social skills improve, he or she will become more resilient to potential or real criticism by others Prognosis People with this disorder usually have some ability to relate to others appropriately, and with treatment prognosis is improved More research needed Dependent Personality Disorder The disorder usually appears in early adulthood Allow others to make major decisions for them Actively avoid taking responsibility Easy to get along with Avoid making decisions themselves Afraid of jeopardizing relationships Avoid being alone Feel uncomfortable or helpless Etiology Unknown Some researchers believe an authoritarian or overprotective parenting style can lead to the development of dependent personality traits in people who are susceptible to the disorder Treatments There is no specific treatment for this disorder… Psychotherapy may be useful in gradually helping people to make choices that affect their own life Group therapy also used with these individuals Medication may also be helpful (more research needed) Prognosis Improvements are usually seen only with long-term therapy Difficult and frustrating process Obsessive-Compulsive Personality Disorder A pervasive pattern of preoccupation with orderliness, perfectionism, and mental and interpersonal control, at the expense or flexibility, openness, and efficiency, beginning by early adulthood Occurs in about 1% of population Gender difference: Twice as prevalent among males SYMPTOMS Preoccupied with details, rules, lists, order, organization, or schedules to the extent that the major point of the activity is lost Shows perfectionism that interferes with task completion (e.g., is unable to complete a project because his or her own overly strict standards are not met) Etiology Unknown Behavioral link: Patients with OCPD often recall their parents as being emotionally withholding and either overprotective or over-controlling Prognosis Another difficult one to treat but some hope especially with cognitive/behavior therapies Credits: Note: Some information in this
