Difficulties Doing Research on Personality Disorders
Difficulties in diagnosing personality disorders are caused by a number of factors, including
diagnostic criteria are not as sharply defined as for other Axis I categories
diagnostic categories are not mutually exclusive
personality characteristics are dimensional in nature
*
Difficulties Doing Research on Personality Disorders
Difficulties in studying the causes of personality disorders spring from
The fact that such disorders have received consistent attention only since DSM-III was published in 1980
The fact that these disorders are less amenable to thorough study
The fact that most studies to
date are retrospective
*
Personality Disorders
The DSM groups personality disorders into three clusters:
Cluster A: People who are perceived as odd or eccentric. This cluster includes paranoid, schizoid, and schizotypal personality disorders.
Cluster B: People whose behavior is overly dramatic, emotional, or e
atic. This grouping consists of antisocial, borderline, histrionic, and narcissistic personality disorders.
Cluster C: People who often appear anxious or fearful. This cluster includes avoidant, dependent, and obsessive–compulsive personality disorders.

Categories of Personality Disorders
Provisional categories include
passive-aggressive
depressive

Paranoid Personality Disorde
Paranoid personality disorder - A personality disorder characterized by undue suspiciousness of others’ motives, but not to the point of delusion.
People who have paranoid personality disorder tend to be overly sensitive to criticism, whether real or imagined.
Clinicians need to weigh cultural and sociopolitical factors when a
iving at a diagnosis of paranoid personality disorder.
*
Diagnostic Criterion

suspects, without sufficient basis, that others are exploiting, harming, or deceiving him or he
is preoccupied with unjustified doubts about the loyalty or trustworthiness of friends or associates

anted fear that the information will be used maliciously against him or he
reads benign remarks or events as threatening or demeaning.

sperceives attacks on his or her character or reputation that are not apparent to others and is quick to react angrily or to counter attack
has recu
ent suspicions, without justification, regarding fidelity of spouse or sexual partner.
Schizoid Personality Disorde
Schizoid personality disorder - A personality disorder characterized by persistent lack of interest in social relationships, flattened affect, and social withdrawal.
Often described as a loner or an eccentric, the person with a schizoid personality lacks interest in social relationships.
The person’s emotions usually appear shallow or blunted, but not to the degree found in schizophrenia.

Schizotypal Personality Disorde
Schizotypal personality disorder - A personality disorder characterized by eccentricities of thought and behavior, but without clearly psychotic features.
Schizotypal personality disorder may be slightly more common in males than in females and is believed to affect about 3% of the general population.
Investigators also find higher rates of the disorder among African Americans than among Caucasians or Hispanic Americans.

Suspiciousness or paranoid ideation Inappropriate or constricted affect
Behavior or appearance that is odd, eccentric, or peculia

Antisocial Personality

*
Lifetime prevalences of antisocial personality disorder by gender.
Antisocial personality disorder is more than five times as common among men than women. However, the disorder has been rising more rapidly among women in recent years.
*
Antisocial Behavior and Criminality
We tend to think of antisocial behavior as synonymous with criminal behavior.
Although it is the case that antisocial personality disorder is associated with an increased risk of criminality, not all criminals have antisocial personalities nor do all people with antisocial personality disorder become criminals.
Many people with antisocial personality disorders are law abiding and successful in their careers, even though they may
treat others in a callous and insensitive manner.
*

ing after age 15

upt shifts in mood, lack of a coherent sense of self, and unpredictable, impulsive behavior.

Chronic feelings of emptiness
Inappropriate anger or difficulty controlling anger (e.g., frequent displays of temper, constant anger, recu
ent physical fights).
Transient, stress-related paranoid ideation, delusions or severe dissociative symptoms
Cutting.
People with borderline personalities may engage in impulsive acts of self-mutilation, such as cutting themselves, perhaps as a means of temporarily blocking or escaping from deep, emotional pain.
*
Borderline Personality Disorde
Self-mutilation is sometimes an expression of anger or a means of manipulating others.
Such acts may be intended to counteract self-reported feelings of “numbness,” particularly in times of stress.
Individuals with BPD often have very troubled relationships with their families and others
Splitting - An inability to reconcile the positive and negative aspects of the self and others, resulting in sudden shifts between positive and negative feelings.
