Factors affecting addictive behaviour
  1. Risk factors
    1. Stress - self medication model, used because of perceived stress relief response - coping with daily hassles
      1. NIDA - stressors lead initiation, maintenance & relapse even after long periods of abstinence
        1. Suffers of PTSD more vulnerable due to extreme stress i.e parental loss/child abuse
        2. Driessen et al - 30% drug addicts & 15% alcoholics suffer PTSD
          1. Kook et al - stress reponse is an anti-reward system. Substance abuse leads to dopamine release. Cortico-trophic releasing factor (CRF) secreted by pituitary gland - maintains homeostasis, decreasing dopamine
            1. Constant CRF release turns homeostasis to allostasis, increasing hedonic set point, dopamine doesn't give pleasure
              1. Leads to anhedonia - no pleasure from normal activities
              2. Periods between smoking stressful. Desire for another can cause mental strain
              3. Cloniger - two types of alcoholics type 1 - to reduce anxiety, type 2 - to reduce boredom (more risk takers). Stress a vulnerability to type 1, not all
              4. Peers - peer pressure may explain initiation of addictive behaviour
                1. SLT - observing & imitating others initiates behaviour. Own experiences will determine if behaviour continues
                  1. Duncan et al - exposure to peer models increases likelihood of smoking
                    1. Eiser et al - social status & popularity important rewards
                    2. SIT - group members adopt behaviours of the group. If smoking a key behaviour - its more likely to be picked up
                      1. Sussman & Ames - peer drug use best predictor of future use
                      2. Age
                        1. Brown et al - peer pressure on drug use & smoking decreases in later adolescence, close friends & romantic partners more important
                          1. Prefrontal cortex not developed till 20's - involved in weighing up risks
                            1. Diamond - if you're not a smoker by 21 you're unlikely to ever be
                              1. Shram - adolescence more sensitive to nicotine & less likely to suffer consequences
                              2. Majority of research only into young people, not representative sample
                                1. Swiss health survey - 46% men > 75 drank daily, only 6% 25-34 drank daily
                                2. Research in socially sensitive topic creates ethical issues. Threat of sanction from incriminating evidence may prevent some people coming forward. Pros & cons - further discrimination
                                3. Personality - addictive personality explains why not everyone becomes addicted
                                  1. Eysenck - 3 personality types that may make you more vulnerable
                                    1. Psychoticism - aggressive, cold, impulsive, egocentric
                                      1. Neuroticism - moody, irritable, anxious

                                                1. Buckholtz et al - more hypersensitive dopamine response - heightened response to anticipated reward
