Presentation
Systematic desensitization is a behavioral therapy technique developed in the 1950s by Joseph Wolpe, a South African psychiatrist. Based on the principle of reciprocal inhibition — the idea that it is physiologically impossible to simultaneously feel anxiety and deep relaxation — this technique pairs deep muscle relaxation with gradual imaginal exposure to anxiety-provoking stimuli.
It is one of the first behavioral techniques rigorously validated by scientific research and remains a reference for treating specific phobias. The method paved the way for all modern exposure therapies.
Founder: Joseph Wolpe (1915–1997), psychiatrist, South Africa / United States
Core Principles
The reciprocal inhibition (counter-conditioning) principle states that if an anxiety-incompatible response (relaxation) is repeatedly paired with anxiety-provoking stimuli, the anxiety response progressively weakens. The process involves three steps: learning Jacobson's progressive muscle relaxation, constructing a hierarchy of anxiety-provoking situations ranked by intensity (0-100 SUD), and gradual imaginal exposure to each hierarchy level while maintaining relaxation.
Main Indications
- Specific phobias (animals, heights, flying, blood, needles)
- Social phobia
- Performance anxiety (exams, public speaking)
- Dental or medical procedure fear
- Mild to moderate anxiety
Session Overview
The protocol unfolds in 3 phases over 8 to 15 sessions. Phase 1 (2-3 sessions): Jacobson's progressive muscle relaxation training. Phase 2: fear hierarchy construction (10-15 situations ranked least to most anxiety-provoking). Phase 3: gradual imaginal exposure — the relaxed patient visualizes each hierarchy situation starting with the least anxiety-provoking. If anxiety appears, they return to relaxation before resuming. Progression to the next level occurs only when the previous level no longer generates anxiety.
Variations and Sub-techniques
- Imaginal systematic desensitization (classical format)
- In vivo desensitization (real gradual exposure)
- Virtual reality desensitization
- Biofeedback-assisted desensitization
- Flooding (immersion — opposite approach, intensive exposure)
Contraindications
- Inability to achieve sufficient relaxation state
- Acute psychotic disorders
- Severe cardiac pathology (for in vivo version)
- Severe untreated panic disorder
