Addiction Flashcards
(Smoking) Biological Initiation: Vink et al.
Studied 1572 Dutch twins
For both sexes, smoking initiation was explained by genetics (44%) and environmental influences (56%)
(Smoking) Biological Initiation: Family and Twin studies
Estimate the heritability of tobacco smoking to be between 39% and 80%
(Smoking) Biological Initiation: Boardman et al.
Conducted a US study of 348 MZ and 321 same-sex DZ twins
Estimated heritability for regular smoking to be 42%
(Smoking) Biological Maintenance: Buka
Mothers smoking during pregnancy doesn’t effect whether the child will later start smoking or not but does double the chances of addiction if they do
(Smoking) Biological Maintenance: Vink et al.
Affects brain chemistry by activating receptors on the brain leading to the release of dopamine
Creates short-term feelings of pleasure
Then this drops to impairment of mood and concentration due to nicotine level reductions
This is alleviated by smoking another cigarette
(Smoking) Biological Relpase: Khaled
Long term smoking has an adverse effect on mood because it permanently alters brain chemistry and smoking again alleviates this in the short term
(Smoking) Biological relapse: Uhl et al.
Research has tried to identify genes associated with quit success (not yet found)
(Smoking) Cognitive Initiation: Mermelstein et al.
Mermelstein et al also suggests that the expectation of states such as relaxation and increased self-confidence are reasons for adolescents beginning smoking.
(Smoking) Cognitive Initiation: Brandon et al.
Expectancy theory is used to explain how a behaviour escalates into an addiction. Brandon et al suggest this is because of the individual’s expectations of the costs and benefits of an activity. For example adolescents may smoke when they are experiencing a negative mood as their expectation is that the cigarette will improve their mood.
(Smoking) Cognitive Maintenance: Automatic Processing
Automatic processing suggests that as an addiction develops, it is less about conscious expectancies and more about unconscious expectancies. This tries to explain the loss of control that many addicts experience.
(Smoking) Cognitive maintenance/relapse: tate et al.
Supportive research. Tate et al. told smokers to expect no negative experiences during a period of abstinence. This led to fewer reported somatic effects e.g. The ‘shakes’ and psychological effects e.g. Mood disturbance than the control group who were not told. Those told to expect somatic and not psychological problems experiences more severe somatic complaints than the control group who was not told to expect this.
(Smoking) Cognitive Relapse: DeVries and Backbier
Also DeVries and Backbier also suggest that expectations of the pros and cons of smoking and quitting affect their quitting behaviour. Smokers who expect that smoking has more benefits than quitting are more likely to relapse.
(Smoking) Cognitive Relapse: Moolchan et al.
Moolchan et al. demonstrated that nicotine patches only increased cessation rates and reduce relapse rates when accompanied by CBT to change the positive expectancies of smoking
(Smoking) Learning Theory Initiation: Karcher and Fisher
Youth with smoker parents were 1.88 times more likely to take up smoking
With smoker siblings, 2.64 times more likely to take up smoking
With close friends who smoke, 8 times more likely to take up smoking
(Smoking) Learning Theory Initiation: DiBlasio and Benda
Found that peer group influences were the primary influence for adolescents who smoke or take drugs
