Chapter 14

2. Stress & Illness
Stress: the process by which we appraise and cope with environmental threats and challenges; it is not just a stimulus or a response (the negative type we typically think of is called DISTRESS)
Stress arises less from events than how we appraise or assess them
When perceived as challenges, stressors can have positive effects & motivate us (EUSTRESS)
Stressors can also threaten our resources, however.
Job security
Loved ones
Health & security
Self-image
Beliefs

3. Health Psychology Health Psychology
Concerned with how psychosocial factors relate to the promotion and maintenance of health and with the causation, prevention, and treatment of illness
But it doesn’t eliminate the biological aspects
Overall, biopsychosocial model that holds the physical illness is caused by a complex interaction of biological, psychological, and socioculutural

4. Stress is in the Eye of the Holder
Primary appraisal- an initial evaluation of whether an event is 1. irrelevant to you 2. relevant but not threatening to you 3. stressful
If stressful then you make a….
Secondary appraisal- an evaluation of your coping resources and options for dealing with stress

5. Stress Response System
The stress response system is a part of a unified mind-body system
When alerted, the sympathetic nervous system kicks in and release epinephrine and norepinephrine
This is known as the fight or flight system (Cannon)…
Heart racing
Increased respiration
Blood goes to skeletal muscles instead of or digestion
Body releases stored sugar and fat for energy
Hormone cortisol is released in addition to, catecholamines & coticosteroids

6. Other Responses- GAS Withdrawal Support-seeking behavior
General Adaptation Syndrome (GAS)- the body’s response to prolonged stress (Seyle)
-Phase 1: alarm reaction
-Phase 2: resistance
-Phase 3: exhaustion

7. Stressful Life Events
Catastrophes: unpredictable, large-scale events that generally are considered to be threatening
Acute stress: threatening events that have a relatively short duration and clear endpoint
Life Changes: significant alterations in one’s living circumstances that require readjustment
Social Readjustment Scale p. 566

8. Different Types of Stress
Daily Hassles: everyday stressors
Frustration: occurs in any situation in which the pursuit of some goal is thwarted, such as traffic jams…can lead to anger, physical symptoms, & significant stress
Chronic stress: threatening events that have relatively long duration and no readily apparent time limit
Conflict: when two or more incompatible motivations or behavioral impulses compete for expression
Such conditions are extra stressful when we perceive them as negative and uncontrollable
- poverty & inequality
- optimism and pessimism

9. Kurt Lewin’s Motivational Theory of Conflict
Approach-avoidance conflict :
There is a conflict between something you want to approach and something you want to avoid. Ex. You want a car but you want to avoid the cost/time/work involved with owning one. OR You want closeness/romance but you want to avoid the cost/time/work/sacrifice/heart break involved in maintaining a relationship.
approach-approach conflict: there are two positive options
Ex. Acceptance to both Harvard and Yale
avoidance-avoidance conflict: there are two negative options
Ex. Would You Rather questions
Multiple approach-avoidance conflict:
Several courses of action that have both positive and negative aspects
Ex. You can ride to the movies on the bus, getting a good seat in time to see the previews, but then have no money to buy popcorn OR have your parents drive you but then have to make dinner and wash dishes OR walk which will probably lead to a bad seat and missing the beginning of the movie, but you can buy popcorn and avoid chores

10. Stress & Heart Disease
Coronary heart disease: the closing of the vessels that nourish the heart muscle
Does stress led to heart disease?
Friedman & Rosenman discovered that those who are Type A are more prone to heart attacks
-Type A: emotionally reactive, competitive, hard-driving, impatient, time-conscious, super-motivated, verbally aggressive, & easily angered
-Type B: easy-going, relaxed

11. Stress & Other Diseases
Psychophysiological illness: stress-related physical illness such as hypertension and some headaches
Stress & the immune system:
Immune system either over-attacks or under-attacks
Stress & AIDS
- the depression of the immune system (decreased production of lymphocytes) in response to stress causes HIV to more quickly progress into AIDS and a more speedy rate of decline
Stress & Cancer
-not a direct link but slightly higher risk within a year of people experiencing depression, helplessness, or grief

12. Stress & Coping Mechanism
