Specific Personality Disorders

The DSM-5 outlines 3 steps for clinical psychologists to make accurate diagnoses. This new model emphasizes the description of the psychological difficulty and the degree of the associated problems. 

Diagnosing Personality Disorders

The newest section of the DSM-5 outlines 6 main personality disorders (schizotypal, antisocial, borderline, narcissistic, avoidant, and obsessive–compulsive personality disorder) that come from the 10 disorders (paranoid, schizoid, schizotypal, antisocial, borderline, histrionic, narcissistic, avoidant, dependent and obsessive–compulsive personality disorder) described in the traditional section.

Main Personality Disorders

“Dark personalities” refer to a set of socially aversive traits in the subclinical range. People with dark personalities don't meet enough of the criteria to be diagnosed with any of the disorders in a clinical setting and are able to flourish in everyday work settings, scholastic settings, and the broader community.

A comprehensive understanding of personality disorders requires achieving several key learning objectives. These include explaining the essential nature of these disorders and how they differ from other psychological conditions, identifying and contrasting the three distinct clusters of personality disorders, and recognizing the primary features and etiological factors associated with both borderline and antisocial personality disorders.

Learning Objectives for Personality Disorders

The enduring and maladaptive personality styles associated with personality disorders are deeply troubling and problematic for both the individuals and those around them. These styles often lead to interpersonal conflicts, hinder the formation and maintenance of social relationships, and obstruct the achievement of personal life goals.

Consequences of Maladaptive Personality Styles in Personality Disorders

The DSM-5 organizes the 10 recognized personality disorders into three distinct clusters based on shared traits. Cluster A is characterized by odd or eccentric behaviors; Cluster B by impulsive, dramatic, emotional, and erratic behaviors; and Cluster C by nervous and fearful behaviors.

Personality Disorder Clusters in the DSM-5

Based on 2007 research, it is estimated that slightly more than 9% of the United States population is affected by a personality disorder.

Prevalence of Personality Disorders in the U.S.

Within the field of psychology, borderline personality disorder and antisocial personality disorder are widely regarded as being particularly challenging and problematic.

Especially Problematic Personality Disorders

The DSM-5 offers an alternative framework for conceptualizing personality disorders, which is derived from the Five Factor Model of personality. This model assesses personality functioning by evaluating impairments in two primary domains: self-functioning (which includes identity and self-direction) and interpersonal functioning (which includes empathy and intimacy).

Alternative DSM-5 Model for Personality Disorders

A clinician is evaluating several clients. Which of the following descriptions provides the strongest evidence for a potential personality disorder, based on the fundamental definition of this category of disorders?

A personality disorder is defined by a pervasive and inflexible personality style that significantly deviates from cultural norms, causing problems for the individual and for others. This pattern typically emerges during adolescence or early adulthood and leads to significant distress or functional impairment.

Psychological disorders are broadly characterized as conditions involving abnormal thoughts, feelings, and behaviors. More formally, the American Psychiatric Association (APA) defines a psychological disorder as a syndrome that includes a clinically significant disturbance in an individual's cognition, emotion regulation, or behavior. This disturbance is understood to reflect a dysfunction in the underlying psychological, biological, or developmental processes of mental functioning and is typically associated with significant distress or impairment in important areas of life.

[DSM-5] Conduct Disorder Criteria

Borderline Personality Disorder (BPD) is primarily defined by a pervasive pattern of instability across interpersonal relationships, self-image, and mood, combined with significant impulsivity. Individuals with this disorder often experience intense emotions and may engage in frantic behaviors to manage their profound fear of abandonment.

Borderline Personality Disorder

Personality Disorders

Identity relates to things that we hold to be our most basic sense of self (e.g. goals, values, gender, and social roles). It involves a sense of continuity in our lives and helps take action for the future. Identity is one's definition of who they are. 

Aspects of Identity

Personality judgements occur when someone draws conclusions about an individual based on behaviors. These judgements may impact opportunities and expectancies for the target individual. 

Personality Judgements

Personality stability describes the belief that people generally maintain their personality and behaviors throughout life. 

Personality Stability

Following early historical views, Sigmund Freud's psychodynamic perspective became a foundational modern theory, emphasizing the role of early childhood experiences. Subsequently, many other major theoretical perspectives emerged, often in reaction to the psychodynamic approach. These include the learning, humanistic, biological, trait, and cultural perspectives, each offering a different lens through which to understand personality.

Personality development describes changes in personality over time and across the lifespan. 

Personality Development 

Personality encompasses the enduring and unique set of traits and patterns that cause an individual to consistently think, feel, and behave in specific ways. It defines how a person interacts with the world and is generally considered to be long-term, stable, and resistant to change.

References for Personality Psychology

Pathoplastic relationship is a term that describes a bidirectional relationship between psychopathology and personality in which they impact each other’s appearance, presentation, or expression. This means that the appearance of personality can be influenced by the existence of a psychopathology, and the psychopathology’s appearance can also differ depending on an individual’s personality traits. 

Pathoplastic Relationships

Personality psychologists can analyze several types of data to draw conclusions and test hypotheses.

 Common forms of data collection include:

- Self Reports

- Informant Reports

- Life Outcomes

- Behavioral Observations

Important Figures in Personality Psychology

Carl Gustav Jung developed a "Neo-Freudian" theory surrounding Personalities. He describes the Psyche as the main part of his theory, with four different aspects going into it. First is the Psychic Energy, also known as “Libido.” Next, is the principle of opposites, followed by the principle of equivalence. Finally, there is the principle of entropy.

Jung's Theory of Personality

Reference for Pathoplastic Relationships 

A personality trait is a relatively consistent and enduring pattern of thought and behavior that an individual exhibits across various situations and throughout their lifespan. Modern personality research focuses on identifying and measuring these traits to predict behavior.

Personality Trait

The term 'personality' originates from the Latin word 'persona.' In the ancient world, a persona was a theatrical mask used by an actor not to conceal their identity, but rather to represent or project a specific character trait.

Analyzing Behavioral Patterns

The divergent life paths of half-brothers Bill and Roger Clinton serve as a compelling case study. Despite being raised by the same people—their mother and an abusive, alcoholic stepfather—their lives took radically different paths. Bill Clinton became the 42nd President of the United States, while Roger Clinton faced numerous arrests and jail time for drug charges. This stark contrast highlights fundamental questions about why individuals make different choices and what internal forces shape their decisions, which are core inquiries that personality psychology seeks to answer.

The Clinton Brothers: A Case Study in Personality Psychology

Social-personality psychology is an emergent subfield of psychology dedicated to studying the intricate interaction between internal factors, such as personality, and situational factors that collectively influence human behavior.

Social-Personality Psychology

In contrast to early theories that attempted to explain how personality arises, modern personality psychology often takes a quantitative approach. This approach focuses on identifying, measuring, and determining how specific personality traits interact in different contexts to predict how a person will behave.

Quantitative Approach to Personality Psychology

Personality psychology is the branch of psychology that studies personality and its variation among individuals, focusing on understanding how individual differences develop over time (e.g., focusing on individuals' unique patterns of behavior, thought, and emotion).

Definition of Personality Psychology

Feeding and Eating Disorders are characterized by persistent changes to eating or eating-related behaviors that result in altered consumption or absorption of food, significantly impairing an individual’s physical health and/or psychosocial functioning. 

Feeding and Eating Disorders

Mood disorders are defined as severe disturbances in mood and emotions, which can include depression, mania, and elation. Unlike typical emotional fluctuations, the mood shifts experienced in these disorders are extreme, distort an individual's perspective on life, and significantly impair their ability to function in daily activities.

Mood Disorders

Sleep-Wake Disorders are defined using a multidimensional approach due to the expectations for co-existing or comorbid diagnosis in both mental and neurological health. They are largely characterized by individual’s interpretation of having dissatisfying sleep quality, timing, or amount of sleep. These complaints are often expressed alongside issues of distress or impairment during expected daytime activities. 

Sleep-Wake Disorders

Psychotic disorders are severe mental illnesses characterized by thoughts, perceptions, and behaviors that are so impaired the individual cannot function normally and becomes disconnected from reality. This state of being disconnected from the world is known as psychosis. People with these disorders often lose contact with reality and may experience extreme symptoms like hallucinations and delusions. Schizophrenia is a primary example of a psychotic disorder.

Psychotic Disorders

An adjustment disorder (AD) is a reaction to a stressful/significant life change. This reaction is marked by preoccupation with the responsible stressor shown by severe distress (more than what is typically expected) or constant thinking about the consequences of said stressor. This may alter one's mental health as a result. 

Adjustment Disorder

Anxiety disorders are characterized by features of excessive fear and anxiety, as well as related behavioral disturbances. These symptoms are often not temporary and linger beyond typical expectations. Excessiveness of these symptoms is clinician diagnosed with cultural contexts taken into consideration.

Anxiety Disorders

- Falls under the umbrella of substance use disorder. The word "addiction" is not formally recognized in the DSM-5.
- Strong, uncontrollable compulsion to administer a drug of abuse to yourself due to dependence.
- Acts on reward circuitry in the brain (dopamine) and changes the chemical composition of your brain over time.
- According to the DSM 5, only gambling addiction has been listed as a diagnosable disorder, the rest of the behavioral addictions are yet to find themselves a place on the DSM manual.

Addiction

Neurodevelopmental disorders (NDDs) are a grouping of disorders that are characterized by onset during the developmental period and present as deficits in functioning. NDDs were first introduced as a category in the DSM-5 in 2013 

NDDs include 
-Intellectual disability (ID) 
-Communication disorders
-Autism Spectrum Disorder (ASD) 
-Attention-Deficit/Hyperactivity Disorder (ADHD)
-Neurodevelopmental Motor Disorders (including tic disorders) 
-Specific Learning Disorders

Neurodevelopmental Disorders (NDDs)

Addictive disorders characterized by a compulsive pattern of drug use and marked by both physical and psychological dependence on the substance. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) is used by clinicians to diagnose drug use disorders. Individuals with these disorders often consume more of the substance than intended and persist in its use despite significant adverse consequences.

Substance Use Disorders

A personality disorder is a long-term deviation in behavior, thoughts, and feelings from the cultural norm and expectancies. Without treatment, a personality disorder causes distress to the individual and creates problems in functioning. 

Personality disorders

Abnormalities in the development of the nervous system that are influenced by both our genes and the environment. Developmental disorders commonly manifest as behavioral abnormalities.

Developmental Disorders

Disruptive, Impulse-Control, and Conduct Disorders are a group of conditions characterized by problems related to the self-control of emotions and behaviors. These disorders are distinct from other disorders with emotional or behavioral regulation due to the nature that these problems result in violations of the rights of others and/or significant conflict with societal norms or authority figures. These disorders and their presentation can greatly vary within the category, as well as between individuals. 


Disruptive, Impulse-Control, and Conduct Disorders

Neurodevelopmental disorders are a class of conditions typically identified in childhood, characterized by developmental impairments across personal, social, academic, and intellectual domains. Key examples within this category include attention deficit/hyperactivity disorder (ADHD) and autism spectrum disorder.

Neurodevelopmental Disorders

Neurocognitive Disorders are a group of disorders characterized by the primary clinical deficit of the individual being in cognitive functioning that is acquired, not developmental. These disorders have a strongly recognized and researched disease etiology to them making them a unique intersection between psychiatry and pathology. 

Neurocognitive Disorders

Substance-Related and Addictive Disorders are characterized by abusing the activation of the brain reward system through certain behaviors or the use of pharmacological substances. This often results in a sense of increased pleasure, or a “high”, encouraging reinforcement of behaviors and actions that are detrimental to or neglectful of daily activities. Due to insufficient research, repetitive behaviors that have been coined as behavioral addictions (e.g., sex addiction, exercise addiction, or shopping addiction) are excluded from this chapter.

Substance-Related and Addictive Disorders

According to the DSM-5, Depressive Disorders constitute a primary category of mood disorders characterized by depression as their central feature. This group of disorders is recognized by the presence of sad, empty, or irritable moods, along with associated somatic and cognitive changes that significantly impair an individual's ability to function. The specific disorders within this category can vary in their duration, timing, and presumed causes.
