13. Personality disorders

Personality traits are patterns of behavior that reflect how people perceive, relate to, and think about themselves and their environments. These traits enable people to navigate their environments and adjust to social and personal stressors. It's only when personality traits become rigid, self-defeating, or maladaptive and cause serious impairment or anxiety that they are considered personality disorders.

With a personality disorder, one s internal experience and behaviors are noted to differ markedly from the norms of one's culture. According to the DSM-IV diagnostic criteria, a problematic pattern is displayed in two or more of the following areas: cognition, affectivity, interpersonal functioning, and impulse control. This pattern results in distress with social, occupational, or general functioning. Impairment is usually manifested in activities of daily living because dysfunctional behavior is the vehicle used to relate to others and to fulfill basic needs. (For further information, see Personality Clusters.)

PARANOID PERSONALITY DISORDER

The basic feature of paranoid personality disorder is a pervasive mistrust and suspicion of other people. There's constant preoccupation with the idea that others will play tricks, exploit, or inflict harm. People with the disorder are on guard for ever-present dangers perceived to be all around them. They're secretive, hypersensitive, jealous, argumentative, and aggressive. Difficulties seem exaggerated, criticism isn't well accepted, and the insults and injuries that these people sustain are never forgiven. Their interactions are noted to be highly critical, rigid, defensive, cold and uncompromising. Others find them excessively objective, to the exclusion of emotion. They make those around them feel uncomfortable in social situations, and they lack a sense of humor. Because people with this personality disorder are inclined to avoid intimate relationships and demonstrate exaggerated self-importance and self-sufficiency, they're often lonely. They have difficulty accepting others in positions of authority or power, and relationships with peers and coworkers are frequently nonexistent. Paranoid personality disorder is seen most often in men.

SCHIZOID PERSONALITY DISORDER

The basic features of schizoid personality disorder are indifference to interpersonal relationships and an inability to experience a normal range of emotions. People with this disorder have no desire for and don't derive pleasure from social interactions, preferring to engage in solitary activities. They're considered loners with no need for intimacy either inside or outside the family. There's little or no interest in having a sexual relationship with another person. Clients with schizoid personality disorder are often viewed as being shy, aloof and self-centered. Neither accolades nor criticism from others has meaning for them. They can’t experience or express strong emotions, such as happiness and anger. They manifest a flat affect and appear emotionally stilted or cold to other people. Because of impaired social skills and an introverted lifestyle, they experience difficulty with occupations that require interpersonal contact but may succeed at those that rely mostly on mechanical or abstract reasoning skills. Schizoid personality disorder is seen in both women and men.

SCHIZOTYPAL PERSONALITY DISORDER

The basic features of schizoid personality disorder are a reduced capacity for interpersonal relationships and cognitive and perceptual distortions that lead to oddities in speech, behavior, and appearance. People with this disorder have symptoms similar to those of schizophrenia, but the symptoms aren't severe enough to warrant diagnosis of schizophrenia. The problems of relating to other people begin early in adulthood. There's a disturbance in perception and thought content manifested by paranoid ideation, suspicion, magical thinking, and ideas of reference (the belief that the casual speech or acts of others have unusual meaning when, in fact, they don't). People with this disorder demonstrate odd thinking, strange mannerisms, speech peculiarities, and a disheveled and eccentric appearance. They often experience unusual perceptual experiences, such as hearing a voice calling to them. Their thoughts are often vague or inappropriately expressed, and they periodically talk to themselves. In social settings, these people are unable to display a range of typical emotions and can't recognize and respond to usual social cues. Even being in familiar situations generates social anxiety, which is associated with mistrust about the motivations of others. If placed in extremely stressful circumstances, they may briefly experience psychotic symptoms. There's a tendency toward social isolation

Scientists believe that personality disorders are caused by a combination of psychosocial, situational, and biological components. In schizotypal personality disorder, the biological findings are similar to those in schizophrenia (for example, neurotransmitter abnormalities and abnormalities in frontal and limbic systems. cortical regions, and straitum). (See chapter 6, Schizophrenia and other Psychotic Disorders.) Clients also manifest characteristic impairment in information processing and abnormal eye movements.

THERAPIES

It is unlikely that clients will pursue therapy because they are usually unaware of the features of the personality disorder. If help is obtained, it's often sought only when the client experiences a mood disorder, anxiety disorder, or dissociative symptoms as the result of a significant stressor, such as divorce, bereavement trauma, and occupational loss. These clients don't usually remain in therapy for long. The overall purpose of therapy is to establish a helping relationship that provides support and guidance in social situations and relationships.

ANTISOCIAL PERSONALITY DISORDER

The primary features of antisocial personality disorder are irresponsible and asocial behavior, including disregard for the rights of others. These behaviors begin during childhood or early adolescence and persist into adult life. To be diagnosed with antisocial personality disorder, clients must be at least 18 years old and have a history of conduct disorder before age 15. Some typical behaviors during childhood are truancy, stealing, vandalism, running away, substance abuse, fist fights, weapons, use arson, cruelty and brutality to people and animals, and sexual aggression. Adults with antisocial personality disorder are irritable, aggressive, and reckless and seek immediate gratification. They act out by abusing others, stealing, destroying property, getting into debt, and engaging in criminal behaviors. Often, these inappropriate actions are preludes to confrontation with law enforcement agencies. Although people with antisocial personality disorder may be superficially charming, they have a blatant disregard for the truth, fail to conform to social norms, have no feelings of remorse or regret, and often express justification for mistreating others. The deceitful and manipulative behaviors are consistently used to secure pleasure, power, or profit.

BORDERLINE PERSONALITY DISORDER

The primary feature of borderline personality disorder is a marked instability in interpersonal relationships, self-concept, and mood as a reaction to the fear of real or imagined abandonment. Clients may experience transient paranoid ideation or severe dissociative symptoms during periods of intense stress. There's an alteration between the extreme positions of idealizing other people and devaluing them. This defense mechanism is known as splitting.

People with this disorder are impulsive, reckless, and cognitively impaired: they act out in self-destructive ways, such as shoplifting, self-abuse, and binge eating. In the clinical setting they can present as extremely anxious, unstable, angry, impulsive, and destructive of themselves and others. Many clients perform self-mutilating actions and have recurrent suicidal thoughts or behaviors. The dramatic behaviors may be for the purpose of manipulating others, or they may result from intense anger or extreme stress.

HISTRIONIC PERSONALLY DISORDER

The major characteristic of histrionic personality disorder is excessively dramatic, attention-seeking behavior that begins early in the adult years. People with this disorder have a driving need to be the center of attention and become uncomfortable when they aren't in this position, regardless of whether this is appropriate for the situation. These clients also display exaggerated emotional responses and overreaction to minor frustrations and annoyances. Their opinions are dramatically expressed without rationale or supportive information. People with histrionic personalities are self-absorbed, often exhibiting temper tantrums when immediate gratification of their needs doesn't occur. They're unable to have successful relationships because they are inconsiderate, dependent, and controlling. They exhibit superficial and rapidly shifting emotional expression. People with histrionic personalities may have difficulty forming a lasting sexual partnership because they may resort to sexually provocative behavior with occupational colleagues or social acquaintances in order to be the center of attention. Even in casual, everyday contact with others, clients with histrionic personality disorder create situations so that they're competing with people of the same sex and seducing people of the opposite sex.

NARCISSISTIC PERSONALITY DISORDER

The key characteristic of narcissistic personality disorder is an exaggerated sense of self-importance. There's a powerful feeling of entitlement and a desire for special attention and constant admiration. People with this disorder overrate their own talents arc accomplishments, are arrogant, and exploit others for the purpose of meeting their personal goals. They're preoccupied with, dreams of success, power, wealth, brilliance, physical appeal, and ideal love. Because these clients believe that they're special they think that they can only be understood or appreciated by other unique individuals. Typically, they believe that others are envious of them, and they can easily become envious of others. Interpersonal relationships are fraught with difficulty because friendships are often formed with the goal of exploiting the other person. There's also a limited ability to be warm, genuine, or empathetic. This disorder occurs in both women and men, but it's much more prevalent in men.

Recent neurobiological research has found evidence of abnormalities in serotonin and dopamine levels in clients with antisocial and borderline personality disorders. Low serotonin levels ha\ e been associated with high levels of aggression and impulsiveness Excessive dopamine levels resulting from impaired metabolism of this chemical also occurs in people with border-line and antisocial personality disorders. The significance of this finding is undetermined. EEC studies disclose abnormal wave patterns in the frontal and temporal lobes in people with borderline personality disorder.

Cluster C Personality Disorders
DSM-IV CATEGORIES
301.82 Avoidant personality disorder
301.6 Dependent personality disorder
301.4 Obsessive-compulsive personality disorder

AVOIDANT PERSONALITY DISORDER

The primary features of avoidant personality disorder are pervasive and repetitive feelings of social discomfort, repetitive feelings of inadequacy in social situations, timid behavior, and abnormal acute sensitivity to criticism. Any remarks or behavior by others that are suggestive of disapproval are automatically interpreted as rejection. An overwhelming fear of non acceptance, disapproval, or rejection causes a strong hesitancy to enter into relationships; hence, people with this disorder usually have no significant others except immediate family members. This personality disorder affects both men and women equally.

DEPENDENT PERSONALITY DISORDER

The primary features of dependent personality disorder are a pervasive and excessive need to be taken care of by others and submissive, clinging behavior toward those people perceived to be the source of care. Clients with dependent personality disorder demonstrate a consistent submissive pattern of allowing others to make decisions for them and run their lives. This over reliance on other people prevents them from accomplishing tasks on their own. They are unable to make everyday decisions without an excessive amount of guidance and reassurance. Dependent personalities are uncomfortable when left alone; they become preoccupied with fear of abandonment or the fear of having to take care of themselves. Criticism by others hurts them severely, yet they frequently agree with the critics, especially if the critic is also the caregiver. The disorder is more frequently diagnosed in women than in men.

OBSESSIVE-COMPULSIVE PERSONALITY DISORDER

The main feature of obsessive-compulsive personality disorder is the person's preoccupation with rules, regulations, and perfection. Inflexible adherence to rules and order permeates all tasks and goals at the expense of flexibility and spontaneity. The person's perfectionism often interferes with completing the task. Frequently, no matter how perfectly detailed an accomplishment is, the person with this disorder believes that the result isn't good enough and continues to look for ways to improve it. Typically, this person is focused on work and goal attainment to the exclusion of friendships and leisure activities. Men are more commonly affected with obsessive-compulsive personality disorder than are women.
