Topic 5.5: Treatment of Psychological Disorders

The Big Picture: Healing the Mind

Congratulations! You have reached the final topic in the AP Psychology curriculum. After spending the previous section exploring the diagnostic criteria for various psychological disorders, it is time to look at how we treat them. Treatment plans today often rely on an integrated approach, combining psychological talk therapies, behavioral conditioning, and biomedical interventions to give individuals the best possible outcomes.

1. Modern Trends and Ethical Foundations

Before diving into specific techniques, it is essential to understand the modern landscape of psychological treatment. Meta-analytic studies—research that combines data from many different studies—show consistently that psychotherapies are generally effective. Modern psychologists rely heavily on Evidence-Based Interventions, which are treatments rigorously tested and supported by scientific research.

• The Therapeutic Alliance: For therapy to be successful, there must be a collaborative, trusting relationship between the therapist and the client. Building this alliance requires the therapist to practice Cultural Humility: a continuous process of self-reflection, openness, and respect for the client's unique cultural background and lived experiences.
• Deinstitutionalization: In the late 20th century, the discovery and widespread use of effective psychotropic medications led to a massive shift in mental health care. Hospitals and asylums discharged large numbers of patients, moving toward decentralized, community-based care—a process known as deinstitutionalization. Today, therapists often prefer to treat individuals using a combination of medication and psychological therapies.
• Ethical Principles: The American Psychological Association (APA) establishes strict ethical guidelines for clinicians, including:
  • Nonmaleficence: The obligation to avoid causing harm and to protect the well-being and safety of clients.
  • Fidelity: Keeping promises, building trust, and upholding professional responsibilities.
  • Integrity: Promoting honesty, accuracy, and truthfulness in therapeutic practices.
  • Respect for People’s Rights and Dignity: Honoring privacy, confidentiality, autonomy, and cultural differences.

2. Psychological Therapies

Psychological therapies (often called psychotherapy or "talk therapy") involve interactions between a trained therapist and an individual seeking to overcome difficulties or achieve personal growth. Different psychological perspectives offer unique treatment techniques.

Psychodynamic Therapies

Rooted in Freud’s psychoanalytic tradition, these therapies focus on exploring unconscious thoughts, unresolved conflicts, and early childhood experiences. Therapists often use Free Association (encouraging clients to express thoughts without censorship) and Dream Interpretation to bypass the conscious mind and uncover hidden psychological tensions.

Humanistic Therapies

Humanistic therapies emphasize human potential, self-awareness, and personal growth. The most prominent is Carl Rogers' Person-Centered Therapy, which relies on a few core techniques:

• Active Listening: The therapist carefully listens, echoes, reflects, and clarifies what the client is saying to ensure they feel entirely heard and understood.
• Unconditional Positive Regard: Providing complete, nonjudgmental acceptance and support, regardless of what the client says or does, fostering a safe space for true self-exploration.

Behavioral Therapies (Applied Behavior Analysis)

Unlike psychodynamic or humanistic approaches, behavioral therapies do not focus on deep, underlying causes or the unconscious mind. Instead, they view disorders as learned behaviors that can be "unlearned" through the principles of classical and operant conditioning—a process known as Applied Behavior Analysis.

• Exposure Therapies: Used heavily for anxiety and phobias, this involves gradually and safely exposing a person to their feared stimulus.
  • Systematic Desensitization: A specific type of exposure therapy where a client creates a Fear Hierarchy (a ranked list from least to most scary scenarios). The client is then taught relaxation techniques and gradually exposed to the items on the hierarchy, pairing the feared object with a relaxed state rather than an anxious one.
• Aversion Therapies: This technique creates a *negative* association. It pairs an unwanted, harmful behavior (like drinking alcohol or biting nails) with an unpleasant stimulus (like a nausea-inducing drug or a foul taste) to reduce the behavior.
• Token Economies: An operant conditioning technique often used in schools or inpatient facilities where individuals earn tokens for exhibiting desired, healthy behaviors. These tokens can later be exchanged for privileges or treats.
• Biofeedback: Using electronic monitoring devices, clients learn to gain voluntary control over physiological processes (like heart rate or muscle tension) to help regulate the autonomic nervous systems and reduce feelings of anxiety.

Cognitive & Cognitive-Behavioral Therapies

Cognitive Therapies assume that our thoughts directly influence our emotions and behaviors. The goal is to identify and change Maladaptive Thinking (inaccurate, overly negative thoughts). Therapists use Cognitive Restructuring to help clients challenge irrational beliefs and replace them with realistic ones.

• The Cognitive Triad: Proposed by Aaron Beck, this concept states that depression is fueled by a pattern of negative thoughts about oneself, the world, and the future. Cognitive therapy explicitly works to dismantle this triad.

Cognitive-Behavioral Therapies (CBT) are highly popular, evidence-based approaches that combine cognitive restructuring with behavioral modification. Notable examples include:

• Rational Emotive Behavior Therapy (REBT): Developed by Albert Ellis, this aggressive therapy vigorously challenges a person's illogical, self-defeating attitudes and assumptions.
• Dialectical Behavior Therapy (DBT): Designed originally for Borderline Personality Disorder, it combines CBT techniques with mindfulness and acceptance strategies to help individuals regulate intense emotions and reduce self-destructive behaviors.

3. Group Therapy & Hypnosis

While most therapies can be conducted one-on-one, Group Therapy offers unique advantages. By treating several clients at once, therapists allow individuals to share experiences, realize they are not alone, provide mutual support, and actively practice social skills in a safe environment.

Another specialized technique is Hypnosis, which involves a focused state of attention and heightened suggestibility. It is important to know the boundaries of hypnosis for the AP Exam: research shows it is effective for treating pain and managing anxiety, but it is not supported for retrieving accurate repressed memories or regressing individuals to an earlier age.

4. Biomedical Interventions

Deriving from the biological perspective, these treatments address the physical, biochemical, or neurological roots of psychological disorders.

Psychotropic Medications

These drugs alter brain chemistry by interacting with specific neurotransmitters in the central nervous system:

• Antianxiety Drugs: (e.g., Xanax, Ativan) Depress central nervous system activity to calm individuals and reduce acute anxiety symptoms.
• Antidepressants: (e.g., Prozac, Zoloft) Often classified as SSRIs (Selective Serotonin Reuptake Inhibitors), they increase the availability of neurotransmitters like serotonin and norepinephrine to elevate mood.
• Lithium: A simple salt that acts as a highly effective mood-stabilizing medication, specifically used to treat the extreme manic highs and depressive lows of bipolar disorder.
• Antipsychotic Medications: (e.g., Thorazine, Haldol) Used to treat schizophrenia and other severe thought disorders. They primarily work by blocking dopamine receptors.
  • Warning: Long-term use of older antipsychotics can lead to Tardive Dyskinesia, a severe side effect characterized by involuntary, repetitive muscle movements, especially in the face, tongue, and limbs.

Brain Stimulation & Psychosurgery

When psychological therapies and medications fail to work, clinicians may turn to more invasive biomedical procedures:

• Electroconvulsive Therapy (ECT): A biomedical treatment for severe, treatment-resistant depression. It involves applying controlled electrical currents to the brain to trigger a brief, therapeutic seizure, which can rapidly relieve symptoms.
• Transcranial Magnetic Stimulation (TMS): A newer, non-invasive alternative to ECT that uses magnetic pulses to stimulate specific, targeted areas of the brain to treat depression without inducing a seizure.
• Psychosurgery: The most drastic and irreversible intervention, involving surgically altering or destroying brain tissue (Lesioning). In the mid-20th century, the Lobotomy (cutting the nerves connecting the frontal lobes to the inner brain) was used to calm violent patients, but thanks to modern medications, it is rarely, if ever, performed today.

Don't Trip Up! (Common Misconceptions)

⚠️ Systematic Desensitization vs. Aversion Therapy: Both are behavioral therapies based on classical conditioning, but their goals are opposites. Systematic desensitization aims to remove a fear response (relaxing in the presence of a spider). Aversion therapy aims to create a negative response (feeling nauseous when tasting alcohol).

⚠️ The Truth About Hypnosis: The AP Exam loves to test the limitations of hypnosis. If a question asks whether a therapist can use hypnosis to uncover a "lost" childhood memory to solve a trauma, the answer is no! Hypnosis often creates false memories due to high suggestibility. It is only proven effective for pain management and relaxation.

⚠️ Schizophrenia & Tardive Dyskinesia: Tardive Dyskinesia is not a symptom of schizophrenia; it is a physical side effect of the medication used to treat schizophrenia (antipsychotics blocking dopamine). Read case studies carefully to see if the involuntary movements started before or after medication was prescribed!
