Question

Explain the effectiveness of various forms of behaviour therapy.

Answer 1

1. Systematic Desensitization:
   • Technique: Gradual exposure to a feared stimulus while practicing relaxation.
   • Effectiveness: Highly effective for phobias and anxiety disorders. It helps reduce avoidance behavior and promotes relaxation responses in place of fear.
2. Flooding (Implosive Therapy):
   • Technique: Prolonged exposure to the most feared stimulus until the anxiety subsides.
   • Effectiveness: Rapid results for specific phobias and PTSD but can be distressing and is less preferred due to ethical concerns.
3. Aversion Therapy:
   • Technique: Unpleasant stimuli (e.g., electric shocks, bad tastes) are paired with undesirable behaviors like smoking or alcohol consumption.
   • Effectiveness: Mixed results. Temporarily suppresses behaviors, but relapse is common unless combined with other therapies.
4. Token Economy: 
   • Technique: Positive behaviors are reinforced with tokens that can be exchanged for rewards.
   • Effectiveness: Particularly useful in institutional settings (e.g., for children with developmental disorders or patients in psychiatric hospitals).
5. Contingency Management:
   • Technique: Systematic application of reinforcements and punishments based on behavior.
   • Effectiveness: Strong evidence for effectiveness in treating substance abuse and promoting adherence to treatment regimens.
6. Modeling (Observational Learning):
   • Technique: Clients learn behaviors by observing others, especially role models.
   • Effectiveness: Effective for social skills training and phobias; works well with children and adolescents.
7. Cognitive-Behavioral Therapy (CBT):
   • Technique: Combines cognitive restructuring with behavioral techniques like exposure, reinforcement, and activity scheduling.
   • Effectiveness: Strong empirical support for depression, anxiety disorders, OCD, PTSD, and eating disorders.
