Psychological Disorders Flashcards
Abnormal Behavior

- Involuntary Commitment: Legal process for people with mental illness who pose a danger to themselves or others.
Disorders Interfere with Our Lives
- Psychopathology: Sickness or disorder of the mind.
- Drawing the Line: Distinguishing between normal emotions, thoughts, and behaviors versus a psychological disorder can be challenging.
- Disruption and Distress: A psychological problem is considered a disorder when it significantly disrupts a person’s life and causes distress over a long period.
Limitations of the Criteria for Disordered Emotions, Thoughts, and/or Behaviors
- Cultural Norms: Deviation from cultural norms varies based on individual beliefs.
- Example: Eccentric behavior may be more tolerated in wealthy communities.
- Maladaptive Behavior: Not every maladaptive behavior is a disorder.
- Example: Talking on a cell phone while driving.
- Personal Distress: Distress does not always indicate a psychological disorder.
- Example: Distress about reactions to sexual orientation.
- Discomfort to Others: Causing discomfort to others does not necessarily equate to a disorder.
The Biopsychosocial Model
- Diathesis-Stress Model:
- Diathesis: An inherited predisposition or vulnerability.
- Stress: Environmental stressors.
- Development of Disorder: The stronger the diathesis, the less stress is needed to trigger the disorder.
- Factors Contributing to Psychological Disorders:
- Prenatal trauma.
- Childhood sexual or physical abuse.
- Family conflict.
- Significant life changes.
The Diathesis-Stress Model
- Definition: A disorder develops when an underlying vulnerability is coupled with a precipitating event.
- Onset of Mental Disorders: Occurs due to both vulnerability and stressful events.
Assessment and Categorization of Disordered Thoughts, Emotions, and/or Behaviors
- Assessment:
- Categorize thoughts, emotions, and behaviors to make a diagnosis.
- Provide appropriate treatment.
- Understand the condition's course and probable outcome (prognosis).
- Methods of Assessment:
- Interviews.
- Self-reports.
- Observations.
- Psychological testing.
- Process: Assessment → Diagnosis → Treatment → Ongoing assessment.
