Abnormal Psychology: History, Theories & Definitions

TAKEAWAYS:

• Abnormal psychology evolved from demonic possession theories to modern biopsychosocial models, shaped by cultural and scientific shifts.
• Theoretical frameworks (biological, behavioral, cognitive, psychodynamic, humanistic, sociocultural) explain abnormal behavior differently, often intersecting in real cases.
• Definitions of abnormality (clinical significance, statistical rarity, subjective distress, maladaptive behavior) are debated but used together in diagnosis.
• Cultural and ethical considerations (e.g., DSM-5’s cultural formulation interview) are critical to avoid bias in assessment and treatment.
• Mental status examination (MSE) and cultural interviews are core tools for identifying abnormal behavior, each with strengths and limitations.
• Psychopathology arises from multifactorial interactions—no single theory suffices; integration is key for effective intervention.

1. Defining Abnormal Psychology

Abnormal psychology studies behaviors, thoughts, and emotions that deviate from societal norms, cause distress, or impair functioning. Unlike "normal" psychology, it focuses on psychopathology—the study of mental disorders.

How is "Abnormality" Defined?

Three primary criteria define abnormal behavior, often used together in clinical practice:

1. Clinical Significance (Maladaptive Behavior)

   • Behavior causes distress or impairment in daily life (e.g., social, occupational, or self-care functioning).
   • Example: A person with severe social anxiety avoids work meetings, leading to job loss.
   • IMAGE: social anxiety disorder symptoms | A person with visible signs of distress in a crowded space, avoiding eye contact.

2. Statistical Rarity

   • Behavior is uncommon in a population (e.g., hearing voices when no one is present).
   • Caution: Not all rare behaviors are abnormal (e.g., genius-level intelligence).

3. Subjective Distress

   • The person experiences suffering (e.g., depression, panic attacks).
   • Example: A person with OCD spends hours washing hands, feeling overwhelmed by germs.

4. Violation of Social Norms

   • Behavior is culturally unacceptable (e.g., extreme aggression, bizarre delusions).
   • Note: Norms vary across cultures (e.g., possession trances in some indigenous groups are not seen as pathological).

Worked Example: Cultural Context of Abnormality

Scenario: A Nepali woman experiences trance states during religious rituals, speaking in tongues and exhibiting uncontrollable movements.

• Western perspective: Might diagnose as dissociative disorder or psychosis.
• Hindu/Buddhist perspective: Seen as divine possession (e.g., by deities like Kali or Durga), not abnormal.
• Key takeaway: Abnormality is context-dependent; cultural relativism is essential in diagnosis.

2. Historical Perspectives on Abnormal Behavior

Abnormal psychology’s understanding has shifted from supernatural explanations to scientific models. Below is a timeline of key historical views:

Key Historical Figures & Their Contributions

---

Real-World Example: eSewa’s "Fear of Online Transactions"

• Behavior: Some Nepali users avoid eSewa due to irrational fear of fraud (e.g., panic attacks before paying bills).
• Historical Parallel: In the 19th century, hysteria (a psychodynamic term) was used for unexplained physical symptoms—similar to how modern anxiety disorders are treated.
• Modern Approach: Cognitive-behavioral therapy (CBT) helps reframe catastrophic thoughts about online scams.

3. Theoretical Frameworks Explaining Abnormal Behavior

No single theory explains all psychopathology; integration is key. Below are five major perspectives, each with strengths and limitations:

A. Biological Perspective

Core Idea: Abnormal behavior arises from neurological, genetic, or biochemical dysfunctions.

• Key Factors:
  • Genetics: Twin studies show heritability (e.g., schizophrenia has ~80% genetic link).
  • Neurochemistry: Imbalance in serotonin, dopamine, GABA (e.g., depression linked to low serotonin).
  • Brain Structure: Enlarged ventricles in schizophrenia, hippocampal atrophy in PTSD.
• Example: Bipolar disorder is linked to dysregulation in dopamine and glutamate.
• Treatment: Medications (e.g., SSRIs for depression, lithium for bipolar disorder).
• Limitations: Ignores environmental/social factors; "biological determinism" risks oversimplification.

B. Psychodynamic Perspective (Freud & Neo-Freudians)

Core Idea: Abnormal behavior stems from unconscious conflicts, childhood trauma, or defense mechanisms.

• Key Concepts:
  • Id, Ego, Superego: Conflict between instincts (id), reality (ego), and morality (superego).
  • Defense Mechanisms: Repression, denial, projection (e.g., a person with low self-esteem projects their flaws onto others).
  • Fixation: Stuck at an early psychosexual stage (e.g., anal-retentive personality).
• Example: A patient with phobias may have unresolved childhood fear (e.g., fear of dogs from a childhood attack).
• Treatment: Psychoanalysis, insight therapy.
• Limitations: Hard to test scientifically; overemphasis on childhood.

C. Behavioral Perspective (Skinner, Watson)

Core Idea: Abnormal behavior is learned through conditioning (classical or operant).

• Key Processes:
  • Classical Conditioning: Pairing a neutral stimulus with an aversive one (e.g., fear of dogs after being bitten).
  • Operant Conditioning: Reinforcement/punishment shapes behavior (e.g., avoiding social situations to escape criticism).
• Example: Obsessive-Compulsive Disorder (OCD): Compulsive handwashing is reinforced by temporary relief from anxiety.
• Treatment: Exposure therapy (gradual facing of fears), behavior modification.
• Limitations: Ignores cognitive and biological factors; overemphasis on environment.

D. Cognitive Perspective (Beck, Ellis)

Core Idea: Abnormal behavior results from dysfunctional thought patterns (cognitive distortions).

• Key Concepts:
  • Automatic Thoughts: Negative self-talk (e.g., "I’m worthless").
  • Cognitive Triad (Beck): Negative views of self, world, and future (linked to depression).
  • Schema: Deep-seated beliefs (e.g., "I’m unlovable").
• Example: A person with depression interprets neutral events as failures (e.g., "I forgot my keys → I’m incompetent").
• Treatment: Cognitive Behavioral Therapy (CBT).
• Limitations: May underestimate biological/emotional roots.

E. Humanistic Perspective (Rogers, Maslow)

Core Idea: Abnormality arises from lack of self-actualization or conditional positive regard.

• Key Concepts:
  • Incongruence: Mismatch between real self and ideal self.
  • Unconditional Positive Regard: Essential for healthy development (e.g., warm parenting).
• Example: A person with low self-esteem may develop anxiety due to childhood criticism.
• Treatment: Client-centered therapy (empathy, unconditional acceptance).
• Limitations: Less effective for severe disorders; subjective approach.

F. Sociocultural Perspective

Core Idea: Abnormal behavior is shaped by social norms, culture, and environment.

• Key Factors:
  • Social Learning: Modeling abnormal behavior (e.g., aggression in media).
  • Cultural Syndromes: Unique to specific cultures (e.g., ataque de nervios in Latinx communities).
  • Stigma & Labeling: Society’s reactions can reinforce disorders (e.g., schizophrenia stigma leading to isolation).
• Example: Anorexia nervosa is more common in Western cultures with thinness ideals.
• Treatment: Cultural adaptation of therapy, community support.
• Limitations: Hard to isolate from other factors.

4. Assessment of Abnormal Behavior

Accurate assessment is critical for diagnosis and treatment. Methods include:

A. Clinical Interviews

• Structured vs. Unstructured:
  • Structured: Follows a checklist (e.g., SCID for DSM diagnoses).
  • Unstructured: Open-ended (e.g., therapist asks, "How have you been feeling?").
• Example: A therapist asks a patient with depression about sleep patterns, appetite, and suicidal thoughts.

B. Mental Status Examination (MSE)

A systematic evaluation of a patient’s current psychological state. Key components:

C. Psychological Testing

• Intelligence Tests: WAIS (Wechsler Adult Intelligence Scale).
• Personality Tests: MMPI-2 (Minnesota Multiphasic Personality Inventory).
• Neuropsychological Tests: Assess memory, attention (e.g., Trail Making Test for ADHD).

D. Cultural Formulation Interview (CFI)

• Why it’s important: Ensures cultural sensitivity in diagnosis (e.g., avoiding bias in interpreting symptoms).
• Key Questions:
  • How does the patient’s culture explain their symptoms?
  • Are there cultural beliefs about treatment?
• Example: A Nepali patient with trance states may not be diagnosed with psychosis if the therapist understands their cultural context.

---

E. Biological Assessments

• Neuroimaging: fMRI for brain activity (e.g., amygdala hyperactivity in anxiety).
• Genetic Testing: BRCA mutations linked to anxiety disorders.
• Blood Tests: Hormone levels (e.g., cortisol in Cushing’s syndrome).

---

Which Method is Best?

Exam Tip: No single method is "better"—combination is key. For example, a depression diagnosis might use:

1. Clinical interview (MSE) to assess mood.
2. Psychological test (PHQ-9) for severity.
3. Biological test (blood cortisol) to rule out medical causes.

---

5. Multifactorial Models of Psychopathology

No single theory explains all cases. Modern models integrate multiple factors:

A. Diathesis-Stress Model

• Diathesis: Biological/psychological vulnerability (e.g., genetic predisposition to anxiety).
• Stress: Environmental triggers (e.g., trauma, poverty).
• Example: A person with a family history of depression (diathesis) may develop depression after a job loss (stress).

B. Biopsychosocial Model (Engel)

• Biological: Genetics, brain chemistry.
• Psychological: Thoughts, emotions, coping styles.
• Social: Culture, family, socioeconomic status.
• Example: Schizophrenia may involve:
  • Biological: Dopamine dysregulation.
  • Psychological: Paranoid thoughts.
  • Social: Stigma leading to isolation.

In the Real World

1. Pathao’s Driver Anxiety (Behavioral Perspective)

   • Issue: Some Pathao drivers experience panic attacks before picking up passengers due to fear of accidents.
   • Explanation: Learned through classical conditioning (e.g., past near-miss incidents paired with stress).
   • Solution: Exposure therapy (gradual practice in low-risk areas) and cognitive reframing ("I’m prepared").

2. Ncell’s "Digital Addiction" (Sociocultural Perspective)

   • Issue: Nepali youth spend 10+ hours/day on phones, leading to social withdrawal.
   • Explanation: Social norms (peer pressure to be "always online") + dopamine reinforcement (likes, notifications).
   • Solution: Cultural campaigns (e.g., "Digital Detox Week") + parental monitoring apps.

3. NEPSE’s Market Volatility (Cognitive Perspective)

   • Issue: Traders panic-sell during crashes, worsening volatility.
   • Explanation: Cognitive distortions ("The market will collapse forever") trigger irrational decisions.
   • Solution: CBT-based financial coaching to reframe thoughts.

Exam Tip: How to Score Full Marks

1. Define abnormality clearly (use clinical significance + statistical rarity + cultural context).
2. Compare theories (pick 2-3 perspectives and explain how they differ in a case example).
3. Link history to modern practice (e.g., "Freud’s psychodynamic theory influenced CBT").
4. Critique assessment methods (e.g., "MSE is structured but lacks cultural sensitivity").
5. Use real-world examples (e.g., Pathao drivers, Ncell addiction, NEPSE traders).
6. For "which method is better?":
   • Argue no single method is best—combine MSE + CFI + biological tests.
   • Example: "A therapist assessing a Nepali patient with depression should use MSE for symptoms + CFI for cultural context + cortisol test to rule out Cushing’s syndrome."

Final Note: Abnormal psychology is not just about disorders—it’s about understanding human suffering in context. Whether it’s a Pathao driver’s anxiety or a NEPSE trader’s panic, the same principles apply: biology + psychology + society shape behavior. Always integrate theories and respect cultural differences in your answers.
