Case Studies of Erratic Behaviors

• Person on Flight

  • Behavior: Screamed "God you’re my savior!" and exhibited erratic behavior during an entire flight.

  • Context: Her mother had recently died.

  • Inquiry: What caused her behavior? Is this a sign of a psychological disorder?

• Phillip Engle Incident

  • Behavior: Showed up at a pizzeria dressed only in a towel, holding a gun.

  • Context: Accompanied by his 3 young children and had 4 hits of LSD.

  • Inquiry: What caused his behavior? Is this a sign of a psychological disorder?

• Jerry Pagan Case

  • Incident: Bludgeoned, stabbed, and castrated his lover, then spent the next day with the corpse.

  • Inquiry: What caused his behavior? Is this a sign of a psychological disorder?

Classification Guide: DSM-5-TR

• Overview:

  • Published by the American Psychiatric Association.

  • Lists categories of psychological disorders and diagnostic criteria.

  • Utilized by:

  • Researchers, mental health professionals

  • Insurance companies

  • Pharmaceutical companies

  • Policymakers

  • Legal system

  • Significance: Functions as a statistical guide rather than a nosology (the classification of diseases).

  • Convention: Serves as the official diagnostic system in the United States.

Keys to Diagnosis

• Clinical Utility:

  • The DSM should facilitate prognosis determination, treatment planning, and assessment of potential treatment outcomes.

• Complexity in Diagnosis:

  • The determination of psychological disorders incorporates various factors including:

  • Symptom severity

  • Distress level

  • Disability levels

  • Risks and benefits of treatment options

  • Notably, the definition of what constitutes a psychological disorder is often complex and is based on negotiation and consensus.

  • Patients with diagnoses may not require treatment, while those with subclinical symptoms might.

Psychopathology

• Definition:

  • The study of the nature, development, and treatment of psychological disorders.

• Relationship to Nosology:

  • The field aligns more with nosological principles, emphasizing validity (defining disorder boundaries) versus the DSM's focus on reliability (consistency).

Definition of Psychological Disorder (DSM-5-TR)

• Key Aspects:

  • Syndrome characterized by clinically significant disturbances in cognition, emotion regulation, and behavior.

  • Reflects dysfunction in psychological, developmental, or biological functioning.

  • Linked to distress or disability in key social, occupational, or crucial activities.

  • Unrelated to culturally sanctioned responses to common stressors.

Clinically Significant Disturbance

• Challenges in Definition:

  • What defines "clinically significant"? No clear lines exist.

  • Interpretations of what constitutes significant disturbance vary widely across individuals.

  • Distinction: Eccentric behavior versus clinically significant disturbance often arbitrary.

Personal Distress

• Consideration:

  • A person may not display distress yet still have a disorder.

  • Example: Personality disorders may exist without Personal Distress.

• Implication:

  • Distress alone is not a reliable indicator of disorder; scenarios such as childbirth, poverty, or unhealthy relationships may complicate this assessment.

Disability

• Definition:

  • Impairment in social, occupational, or vital activities.

• Examples:

  • Inability to work, interpersonal conflict.

• Caveats:

  • Merely being unable to function does not equate to a mental disorder.

  • Consider physical causes (e.g., injury) or lack of motivation unrelated to mental health.

Predictable and Culturally Sanctioned Responses

• Criteria:

  • Not categorized as an expected or culturally endorsed response to stressors.

• Social Norms:

  • Define beliefs and judgments shaped by geography, culture, and time, often fluid and changeable.

• Not All Norm Violations are Disorders:

  • Examples: Criminal acts or rudeness may not denote disorder.

Dysfunction in Processes

• Key Concept:

  • Dysfunction implies an internal mechanism failing to operate correctly.

• Issue:

  • Many internal mechanisms related to psychological disorders remain unidentified or poorly understood.

Summary

• This course centers on psychological disorders and psychopathology.

• Recognizes the utility of classification systems for structured and reliable diagnosis, albeit noting their challenges in practical application and validity.
