P2.PS.7Interventions for addiction: aversion therapy and self-management programmes (e.g. AA), and their evaluation

Two AQA-named interventions: aversion therapy (a behavioural treatment using classical conditioning) and self-management programmes (e.g. AA-style mutual support).

Aversion therapy

Uses classical conditioning to pair the addictive substance/behaviour with an unpleasant response, breaking the rewarding association.

How it works

1. The substance (or behaviour) is the conditioned stimulus that has been associated with reward (dopamine, relief, social approval).
2. An unconditioned stimulus that produces an aversive unconditioned response is introduced — e.g. a drug that causes nausea.
3. After repeated pairings, the substance itself triggers the aversive response (now conditioned).
4. The person feels nauseous (or otherwise repelled) at the sight, smell or thought of the substance.

Examples

• Disulfiram (Antabuse) for alcohol addiction. The drug blocks an enzyme that metabolises alcohol; drinking even a small amount produces severe nausea, headache, palpitations. Knowing this, the person avoids alcohol; if they do drink, the experience reinforces avoidance.
• Rapid smoking for nicotine addiction — taking puffs every few seconds until the smoker feels ill.
• Imaginal aversion — pairing the substance image with imagined unpleasant scenes (used for behavioural addictions and sex offences).

Strengths

• Direct application of well-established conditioning principles.
• Can produce rapid, measurable reduction in use.
• Useful as adjunct to other treatments — Antabuse helps maintain abstinence in motivated alcoholics.

Weaknesses

• Compliance problem — people stop taking Antabuse so they can drink again.
• Ethical issues — deliberately causing illness; consent must be genuinely informed; older history of aversion therapy (especially for homosexuality in the 1960s–70s) widely condemned.
• Symptom not cause — doesn't address underlying psychological factors (anxiety, trauma, social context).
• Generalisation problem — aversion learned in clinic may not transfer to home environment.
• High relapse rates without follow-up.

Self-management programmes

The model is Alcoholics Anonymous AA and similar 12-step programmes (Narcotics Anonymous, Gamblers Anonymous). Modern variants include SMART Recovery (cognitive-behavioural, secular).

Core elements

• Mutual support — group meetings of people in recovery sharing experiences without professional facilitation.
• 12 steps (in AA) — accepting powerlessness, acknowledging harm, making amends, ongoing self-monitoring. Includes a spiritual element ("higher power") that some find off-putting.
• Sponsor — a more experienced recovering member providing one-to-one support.
• Free, available, lifelong — meetings continue indefinitely; no time-limited "treatment course."
• Lifestyle change — practical strategies (avoiding triggers, building drug-free routines, repairing relationships).

Evidence

• Project MATCH (1997) — large US RCT comparing 12-step facilitation, CBT and motivational therapy for alcoholism. All three roughly equivalent on outcome — 12-step was at least as effective as professional therapies.
• Long-term abstinence rates higher among AA attenders than non-attenders, although selection effects (motivation, social support) confound this.
• Vaillant (1995) found a strong link between AA participation and sustained recovery in long-term follow-up.

Strengths

• Free and widely available — major advantage for low-resource contexts.
• Lifelong support reduces relapse risk that time-limited therapies face.
• Builds drug-free social identity and routines.
• Peer-based — less stigmatising than clinical settings for some.

Weaknesses

• Spiritual elements in 12-step model alienate some users; SMART Recovery offers a secular alternative.
• Self-selection bias in evidence — those who attend may already be more motivated.
• Not a substitute for medical detox in serious physical dependence.
• Variable quality across local groups.

Combining approaches

Most effective treatment is usually multi-component: medical detox + CBT (relapse prevention) + 12-step or SMART Recovery for ongoing support, sometimes with disulfiram or naltrexone as an adjunct.
