1 CHAPTER 13 STRESS, COPING AND HEALTH

2 THE RELATIONSHIP BETWEEN STRESS AND DISEASE Contagious diseases vs. chronic diseases Biopsychosocial model Why? The Biomedical Model is unable to fully account for health Mind-body question Biomedical treatments only Failures to account for many psychological factors and health Placebo effects how to explain Health psychology Health promotion and maintenance Discovery of causation, prevention, and treatment Primary prevention, secondary prevention, tertiary prevention Changing pattern of what is the primary cause of death in last 100+ years. F 13.1

3 Levels of Prevention Primary Prevention Prevent disease Identify causes Promote health behaviors Secondary Prevention Catch disease in early stages Prevent further deterioration Tertiary Prevention Manage illnesses with no cure

6 Psychological Stress Richard Lazarus (1966) defined psychological stress as a generic term for the whole area of problems that includes the stimuli producing stress reactions, the reactions themselves, and the various intervening processes. Lazarus and Folkman (1984) define psychological stress as a particular relationship between the person and the environment that is appraised by the person as taxing or exceeding his or her resources and endangering his or her well being.

7 APPRAISAL PROCESS The primary appraisal process determines whether the environment is perceived as psychologically threatening, harmful, or challenging to the person. The secondary appraisal process is a complex evaluative process in which a person considers resources available to cope with the primarily appraised stressor.

18 RESPONDING TO STRESS PHYSIOLOGICALLY Physiological Responses Fight-or-flight response Selye s General Adaptation Syndrome Alarm Resistance Exhaustion Brain-body pathways in stress Figure 13.6 sympathetic adrenal medullary (SAM) (fast) hypothalamic pituitary adrencortical (HPA) (slow, energy)

19 PHYSIOLOGICAL STRESS Hans Selye first introduced the term stress to medicine in He noted that animals were induced by a variety of stimuli to show the syndrome of just being sick which resulted in adrenal enlargement, gastrointestinal ulcers, shrinkage of the thymus and lymph nodes. This reaction was termed the general adaptation syndrome and stress is the nonspecific response of the body to any demand made upon it.

20 Figure 13.6 Brain-body pathways in stress: SAM and HPA systems Lundberg (2002), [Two] neuroendocrine systems have been of particular interest in the study of stress; the sympathetic adrenal medullary (SAM) system with secretion of the two catecholamines, epinephrine and norepinephrine, and the the hypothalamic pituitary adrencortical (HPA) system with the secretion of cortisol.

21 ALLOSTATIS AND ALLOSTATIC LOADS Allostatis - ability to achieve stability through change... (McEwen, 1998, p.171). Allostatic loads (McEwen, 1998) The first and most obvious is frequent stress (p. 172) Lack of adaptation to a repeated stressor can prolong exposure to stress hormones (p. 172) Inability to shut off allostatic responses after a stress is terminated (p.172) [I]nadequate responses by some allostatic systems trigger compensatory increases in others (p. 173)

22 RESPONDING TO STRESS BEHAVIORALLY Behavioral Responses: Coping emotion focused Frustration-aggression hypothesis catharsis Defensive Coping ego defense mechanisms Freud Table 13.3 Constructive Coping problem focused

23 EMOTION-FOCUSED COPING AND PROBLEM-FOCUSED COPING Emotion-focused (or palliative) coping refers to thoughts or actions whose goal is to relieve the emotional impact of stress. These are apt to be mainly palliative in the sense that such strategies of coping do not actually alter the threatening or damaging conditions but make the person feel better. Monat and Lazarus (1991, p. 6) Problem-focused coping refers to efforts to improve the troubled person-environment relationship by changing things, for example, by seeking information about what to do, by holding back from impulsive and premature actions, and by confronting the person or persons responsible for one s difficulty. Monat and Lazarus (1991, p. 6)

31 FACTORS MODERATING THE IMPACT OF STRESS Social support The perceived comfort, caring, esteem or help received from others. The existence or quantity of social relationships the amount of assistance individuals believe is available to them the amount of assistance individuals receive Alameda County Study in 1965 related to health outcomes, tend to live longer Increased immune functioning Optimism expectation of good things will happen and bad things will not happen, contrasted to pessimism Related to psychological well-being, physical well-being More adaptive coping Pessimistic explanatory style Conscientiousness Fostering better health habits Autonomic reactivity Cardiovascular reactivity to stress

42 STRESS MANAGEMENT TECHNIQUES -ADAPTED FROM MONAT & LAZARUS (1991) Environment/Lifestyle: time management, proper nutrition, exercise, finding alternatives to frustrated goals, stopping bad habits Personality/Perception: assertiveness training, thought stopping, refuting irrational ideas, stress inoculation, modifying type A behavior Biological responses: progressive relaxation, relaxation response, meditation, breathing exercises, biofeedback, autogenics

43 RELAXATION RESPONSE - BENSON The relaxation response is perhaps best understood as a psycho-physiological state of hypoarousal engendered by a multitude of diverse technologies [techniques] (Everly, 1989, p.149) Meditation - a self-generating practice of a variety of techniques designed to induce the relaxation response by use of a repetitive focal device Progressive relaxation - relax selected muscles by first tensing then relaxing the muscles

44 STRESS INOCULATION TRAINING DEVELOPED BY DONALD MEICHENBAUM Stage 1 - education - the person is given a framework for understanding his/her stress response Stage 2 - rehearsal - the person learns to make cognitive selfstatements as a form of coping and problem solving Stage 3 - application - the person uses the information and skills learned in the first two stages in actual stress situations, moving from lower to higher stress situations
