Transcript of PSYA4 - Biological & PHI - Addiction

Biological Interventions
Substitution approaches
Antagonist approaches

Reduce withdrawal symptoms
Works against the addiction
Key Points
1. You will NOT be asked on a specific addiction (smoking or gambling)
2. Question WILL NOT identify one specific intervention (e.g Methadone) or approach
3. Evaluation of psychological or biological interventions should focus on effectiveness - so always ensure your statements focus on whether the interventions are effective or not
4. PHI - Do the above BUT also include methodological issues, problems involving cause and effect as well as referring to effectiveness.
Exam questions used
1. (Jan 2010) Outline two examples of public health interventions aimed at reducing addictive behaviour. (4 marks)
2. (Jun 2011)Discuss one type of intervention aimed at reducing addictive behaviour.
(4 marks + 6 marks)
3. (Jan2012) Outline and evaluate one psychological intervention aimed at reducing addictive
behaviour. (4 marks + 6 marks)
& Public Health Intervention
Biological Interventions
Nicotine replacement Therapy
E.gs of......
What do they do?
Gives out a low dose of nicotine to help to relieve the withdrawal symptoms.
Provide positive reinforcement (arousal & stress-relieving effect)
May also desensitise nicotine receptors in the brain, so a cigarette while on 'patches' is less satsifying.
Ao2 It!
Low nicotine doses are not satisfying
Nicotine itself may be harmful
Cost benefit
Watts el al (2002) - Has reasonable success rates
Issues if pregnant
Evaluation of Biological Interventions
Can be very helpful in reducing addictive behaviour
Especially in people who are very dependant
Critics argue that it takes away responsibility of the individual
Takes away the idea that they have free will and could actually change their behaviour without the help of drugs
Determinsitic approach
Also categories addictive behaviour as a disease
Addictive behaviours involve a complex combination of factors and no single treatment intervention can work alone.
Public Health Interventions
Whats the difference?
Biological (& Psychological) = Targeted at individuals
PHI = Targeted at groups of people
- Education/Guidance
(get the horse to come to you)
- Policy
(make the horse do something)
Public Health Interventions - Overview

Read the NIDA study
a balanced argument
for one intervention
the key points

Real world application - P251 - summarize point

Can you add any detail?
