History of Behavior Therapy

History of Behavior Therapy

• The term "modifying behavior" was used by Joseph Wolpe's research group in the 1940s and 1950s.
• Three main origins of behavior therapy: South Africa (Wolpe's group), the United States (B.F. Skinner), and the United Kingdom (Rachman and Eysenck).
• B.F. Skinner developed operant conditioning in 1937 through experiments with rats and reinforcement/punishment.
• Ivan Pavlov's experiments with dogs are a known example of classical conditioning.
• Mary Cover Jones, considered the "mother of behavior therapy," used exposure therapy with a boy named Peter to overcome his fear of rabbits in 1924.
• Joseph Wolpe refined Jones's techniques in 1958, resulting in modern exposure therapy.
• In the latter half of the 20th century, behavior therapy combined with cognitive therapy formed cognitive behavioral therapy (CBT).

Defining the Behavioral Approach

• Behavior therapy is based on the idea that abnormal behavior is learned and can be unlearned.
• Uses principles of operant conditioning, classical conditioning, and observational learning.
• Aims to eliminate maladaptive behaviors and replace them with adaptive responses.
• Techniques include:
  • Punishment (e.g., timeout, verbal reprimand)
  • Token economies (reinforcement system using tokens exchangeable for privileges or items)
  • Contingency contracts (formal agreements outlining behavior goals, reinforcement, and penalties).
  • Modeling (learning through observation and imitation of adaptive behaviors)

Classical Conditioning Approaches

• Aversive conditioning: Uses an unpleasant stimulus to stop undesirable behavior (e.g., electric shock, bad taste).
• Exposure therapy: Repeated exposure to anxiety-provoking situations to reduce fear responses.
  • In vivo exposure: Exposure to real-life situations.
  • Imaginal exposure: Visualization and mental rehearsal of anxiety-inducing events.

Exposure Therapy Steps

• Therapist and client create a list of anxiety-provoking situations.
• Rank situations from least to most feared using the Subjective Units of Discomfort (SUDS) scale.
• Treatment progresses from least to most feared situations.

Example: Social Anxiety

• Hierarchies are frequently used for social anxiety.
• Starting with imagining social interaction, progressing to real-life situations like conversations and parties.
• Aims to gradually reduce fear and increase comfort in social settings.

Avoiding Safety Behaviors

• Safety behaviors are unnecessary actions that provide perceived comfort or prevent imagined negative outcomes.
• Avoiding safety behaviors is important to allow the client to realize they can manage anxiety without them.

Behavioral Rehearsal

• Role-playing technique where clients practice desired behaviors with therapist.
• Aims to reduce anxiety associated with communicating feelings or engaging in specific behaviors.
• Therapist provides feedback and guidance during rehearsal.
• Suggested steps for implementing behavioral rehearsal:
  • Practice the behavior to be modeled
  • Build client motivation through reinforcement
  • Provide focused feedback
  • Shape and hone behavior using reinforcement

Key Points of Behavioral Rehearsal

• Clients practice six key rules:
  • Express emotions verbally
  • Communicate feelings nonverbally
  • Contradict others when disagreeing
  • Speak from the first person ("I")
  • Agree with therapist praise
  • Be spontaneous and adaptable

Effectiveness of Behavior Therapy

• Proven effective in addressing issues such as:
  • Intimacy in couples
  • Relationships
  • Forgiveness
  • Chronic pain
  • Anorexia
  • Chronic distress
  • Substance abuse
  • Depression
  • Anxiety
  • Insomnia
  • Obesity
• Often considered as effective as drug treatments for depression, ADHD, and OCD.
• Systematic desensitization successful in treating phobias of heights, driving, insects, and anxiety.
• Virtual reality therapy used for fear of heights and other anxiety disorders.
• Applied behavioral analysis (ABA) is a common treatment approach for children with autism.

Key Points

• Focuses on teaching new behaviors to minimize or eliminate problems, unlike insight-based therapies (e.g., psychoanalytic, humanistic).
• Based on behaviorism, which emphasizes observable behavior rather than internal mental processes.
• Uses various techniques based on classical and operant conditioning.
