Sources of Stress • Social Readjustment Rating Scale (SRRS) – – Outline of 43 life events from most to least stressful. Point value assigned to each event. Negative or positive events both cause stress. Point totals describe impact of stress and chance of illness over a two year period. – Score 150 -300 have 50% chance of stress related illness within 2 years. – Score 300 + have 80% chance of stress related illness within 2 years. • Shortcomings of SRRS include: – Individual’s coping styles not taken into account. – Good coping strategies reduce impact of each stressful event WWB Copyright © Allyn & Bacon 2006
Daily Hassles and Uplifts • Hassles • – little stressors including irritating demands that can cause more stress than major life changes. – Irritating, frustrating, distress demands of daily life – Relationship troubles – Health problems – Hectic daily schedules Amount of stress from hassles can vary from person to person. • Hassles are bettor predictors of psychological distress. • Uplifts - positive experiences which may neutralize hassles. • Uplifts for some are hassles for others WWB Ten Most Common Hassles for College Students 1. Troubling thoughts about future 2. Not getting enough sleep 3. Wasting time 4. Inconsiderate Smokers 5. Physical Appearance 6. Too many things to do 7. Misplacing or losing things 8.

Major Types of Stress • Frustration: blocked goal • Conflict: incompatible motivations – Approach-approach – Avoidance-avoidance – Approach-avoidance • Change: having to adapt – Social Readjustment Rating Scale – Life Change Units • Pressure – Perform/conform
Making Choices • Approach-Approach – A choice between two positive alternatives. – Choosing a movie to see – Continuing a career or raising a child • Avoidance-Avoidance: – A forced choice between two negative alternatives. – Avoid studying for a test or failing a test • Approach-Avoidance – A choice that has both a good and bad alternative. – Drawn by a choice and repelled by a choice – Wanting to take a vacation but having to empty your savings account to do it WWB Copyright © Allyn & Bacon 2006

Responding to Stress Emotionally • Emotional responses – Annoyance, anger, rage – Apprehension, anxiety, fear – Dejection, sadness, grief – Positive emotions • Effects of emotional arousal – The inverted-U-hypothesis
Figure 12. 4 Arousal and performance
Responding to Stress • The General Adaptation Syndrome – The predictable sequence of reactions (stages) that organisms show in response to stressors – Alarm Stage • a burst of energy that aids in dealing with the stressful situation – Adrenal cortex releases hormones called glucocorticoids – Increases heart rate, blood pressure, and blood sugar levels – Resistance Stage • Intense physiological efforts to either resist or adapt – Glucocorticoids continue to be released – Length of stage based on stressor intensity and ability to adapt – Exhaustion Stage • Occurs if an organism fails in its efforts to resist the stressor – Stores of energy are depleted – Disintegration and death may follow WWB Copyright © Allyn & Bacon 2006
Responding to Stress Physiologically • Selye’s General Adaptation Syndrome – Alarm – Resistance – Exhaustion • Brain-body pathways – Adrenal gland catecholamines – Pituitary gland corticosteroids
General Adaptation Syndrome Stress Resistance Phase 1: Alarm Reaction Phase 2: Resistance (cope) Phase 3: Exhaustion
Endocrine Responses to Stress • Fight or flight preparation of body • Stress hormones—produced by adrenal glands – Adrenal medulla—catecholamines • Epinephrine and norepinephrine • Increases respiration, BP, heart rate – Adrenal cortex—corticosteroids • Release stored energy • Reduces inflammation and immune system responses
Figure 12. 5 Brain-body pathways in stress
The Immune System and Stress • Negative Effects on the Immune System – Periods of high stress are correlated with • Symptoms of infectious disease • Oral and genital herpes and mononucleosis • Susceptibility to colds and flu – – – Stress may reduce the effectiveness of vaccines Decrease levels of B and T cells Can worsen autoimmune diseases Increase illness behaviors, reporting and seeking medical care Suppresses immune system long after a stressful event is over • Increased academic pressures, poor marital relationships, severe depression, and sleep deprivation due to suppressed immune system • Severe bereavement affects physical and mental ailments up to 2 years following a partner’s death WWB Copyright © Allyn & Bacon 2006
The Immune System and Stress • Psychoneuroimmunology – A field in which psychologists, biologists, and medical researchers combine their expertise to study the effects of psychological factors on the immune system • Psychological factors are related to immune system functioning – Immune system exchanges information with the brain that can enhance or suppress it • Good Effects on Immune System – Rich social life with frequent interaction others – Close social ties to family, friends, co-workers, religious and volunteer groups WWB Copyright © Allyn & Bacon 2006
Stress and Physical Health • Psychosomatic diseases • Heart disease – Type A behavior—three elements • strong competitiveness • impatience and time urgency • anger and hostility – Emotional reactions and depression • Stress and immune functioning – Reduced immune activity
Coronary Heart Disease • Personality Type • Type A Behavior Pattern – Marked by a sense of urgency, impatience, excessive competitiveness, hostility, and anger – Involved in a chronic, incessant struggle to achieve more and more in less and less time – Considered a risk factor in heart disease Hostility is a key component of the Type-A behavior pattern.

Responding to Stress Behaviorally • Coping • Styles of coping – Learned helplessness – Frustration-aggression hypothesis – Self-indulgence – Defensive coping – Constructive coping
Response to Stress • Psychological Factors – Perception of control – Explanatory style – Chronic negative emotions – Hostility • Social Factors – Outside resources – Friends and family – Positive relationships
Factors Moderating the Impact of Stress • Social support – Increased immune functioning • Optimism – More adaptive coping – Pessimistic explanatory style • Positive effects
Personal Support and Stress A strong social support network can help a person recover faster from an illness. WWB Copyright © Allyn & Bacon 2006
Personal Factors Reducing The Impact of Stress and Illness • Optimists – – – Cope more effectively with stress Reduces risk of illness Generally expect good outcomes Find positives even in the darkest circumstances Generally more stress resistant • Pessimists – Expect bad outcomes – Hopelessness • Moderate to high levels died from all causes at two to three times the rates WWB Copyright © Allyn & Bacon 2006
Health-Impairing Behaviors • • Smoking Poor nutrition Lack of exercise Transmission, misconceptions, and prevention of AIDS
Figure 12. 8 The prevalence of smoking in the United States
