D.Include evaluation points that include research (blue and yellow boxes).

Groups and Topics Group 1 – Cardiovascular disorders and anger (acute stressor). Group 2 - Cardiovascular disorders and work- related stress (chronic stressor). Group 3 – Stress and depression. Group 4 – stress and other disorders.

Group 2 - Cardiovascular disorders and work-related stress (chronic stressor). AO1 - Russek (1962) – looked at two types of doctors. GP’s and anesthetists vs pathologists and dermatologists Cardiovascular disease was highest for GP’s and lowest for dermatologists. A02 – Exposure to stress are based on self report questionnaires. People tend to remember more negative things and so might effect how much people report these and link them to stress.

Group 4 – stress and other disorders. Ao1 – Vietnam war veterans. MacNair 2002 – found soldiers who fought in the war had PTSD as well as those with chronic stressors like poverty and abuse. PTSD – creates a loss of faith of safety or predictability.

Group 1 – Cardiovascular disorders and anger (acute stressor). Williams et al (2000) investigate anger and heart disease. 13,000 people completed anger questionnaire. 6 years later those who had a high score on the anger questionnaire were x2.5 more likely to have a heart attack.

Group 3 – Stress and depression. Brown and Harris (1978) found women with chronic stress conditions were more likely to develop depression. Working-class women were more at risk than middle class women. Melchior et al (2007) survey of 1000 people in NZ. 15% in high stress jobs had suffered clinical depression compared with 8% in low stress jobs.

Main AO2 points Heart Disease Exposure to stress are based on self report questionnaires. People tend to remember more negative things and so might effect how much people report these and link them to stress. Sympathetic branch of the ANS in some is more reactive than others (Rozanski et al 1999) This means some people are more at risk from stress than others.

Main Ao2 points - depression Are stressful events the cause of depression or do they happen BECAUSE of the depression. What comes first? Retrospective – Recall of events in the past can be unreliable. The effect of stress on depression appears to be small.

Diathesis model – AO2 According to this model if a person develops a disease or illness it will be because they are genetically vulnerable to a disease or illness for it to develop. Any stress that happens in their life can trigger this genetic vulnerability. This explains why some people can adapt to stress better than others.
