Addiction- risk factors Flashcards
What are the 5 risk factors we look at
1) personality
2) stress
3) peer groups
4) genetic influences
5) family influences
What is inherited which may cause addiction
Genetic vulnerabilities
What gene did Comings et al find to be implicated in addiction
A1DRD2
What does the A1DRD2 gene do
Reduces the number of dopamine receptors are reduced in someone’s brain, meaning they have to go out and try achieve extra stimulation (hence, drugs and alcohol).
What is reward deficiency syndrome
When individuals are less sensitive to rewards and may seek out extra stimulating activities like gambling to compensate
How many of the alcohol dependent user participants had the faulty gene
- Comings et al
69%
How many of the cocaine dependent user participants had the faulty gene
- Comings et al
51%
Evaluation, genes
- Evidence (Shields)
P- There is research to support
E- Using an adoption study, Shields et al (1962) examined the concordance between 42 twin pairs that were reared apart. Only 9 pairs were actually discordant, showing how genetic similarity is a major factor in starting to smoke.
L- support the genetic influence explanation
Evaluation, genes
- Evidence (Shah et al)
P- There is more research to support
E- Shah et al (2005) used adults to find strong evidence of genetic transmission in men. Black et al (2006) also found that 1st degree relatives of gambling addicts were much more likely to suffer the same fate as more distant relatives.
L- shows that genes play a role in addiction
Evaluation, genes
- Practical applications
P- The explanation has practical application
E- By understanding genes are a vulnerability, we can identify what triggers these genes and get individuals to avoid these triggers.
L- Means that the genetic explanation can be used to help addicts
Evaluation, genes
- Issues with concordance rates
P- No genetic explanation can find a 100% concordance rate
E- Therefore, it is likely that the environment plays a role, meaning the genetic explanation has lowered explanatory power. It is also incredibly unlikely that an individual will get addicted to a substance that they have never been exposed to, so the environment clearly does play a part in this.
L- An interactionist explanation may better at explaining
What is acute stress
Everyday stress
What is chronic stress
Traumatic stress
What does the tension-reduction hypothesis state
People may engage in addictive behaviours in an attempt to reduce tension and anxiety
Who developed the tension-reduction hypothesis
Cappell and Greeley
What has research shown about people exploited to chronic stress
They are more vulnerable to addiction
Especially children who have experienced a parental/child abuse
What did Driessen et al find
30% of addicts and 15% of alcoholics also suffered from PTSD
According to Driessen et al
__% of addicts and __% of alcoholics also suffered from PTSD
30
15
What have researcher said about mere trauma
- Not sufficient enough to lead to addiction
- It’s how you internalise them
- Such major life events may not only increase risk of addiction but also make you readjust your life
