Stress And Adaptation

Stress and Adaptation A. Consequences of stress I. stress has numerous consequences a. physiologically i. can threaten a person's physiologic homeostasis b. emotionally i. can produce negative or unconstructive feelings about the self c. intellectually i. can influence a person's perceptual and problem-solving abilities d. socially i. can alter a person's relationships with others e. spiritually i. can challenge one's beliefs and values II. many illnesses have been linked to stress, e.g.: a. skin disorders, e.g.: i. excema ii. urticaria iii. psoriasis b. metabolic disorders, e.g.: i. hyperthyroidism ii. hypothyroidism iii. diabetes c. respiratory disorders, e.g.: i. asthma ii. hay fever iii. tuberculosis d. cardiovascular disorders, e.g.: i. coronary artery disease ii. essential hypertension iii. congestive heart failure e. gastrointestinal disorders, e.g.: i. constipation ii. diarrhea iii. duodenal ulcer iv. anorexia nervosa v. obesity vi. ulcerative colitis f. menstrual irregularities g. musculoskeletal disorders, e.g.: i. rheumatoid arthritis ii. low back pain iii. migraine headache iv. muscle tension h. cancer i. accident proneness B. Stress as a stimulus I. definition of stress as a stimulus a. a life event, life change, and/or set of circumstances causing a disrupted response that increases the individual's vulnerability to illness b. focuses on events rather than reactions or individual differences II. stress as a stimulus was developed by Holmes and Rahe (1967) a. concepts important to Holmes and Rahe's view of stress as a stimulus i. life-change a. a form of stress related to the development of illness ii. life-change is measured on the Social Readjustment Rating Scale (SRRS) iii. the SRRS is a tool that rank-orders life-changes and pre-determined life-change units for each of these life-changes, allowing for no individual perceptions

iv. an individual indicates on the SRRS which life-changes, and the corresponding life-change units, he/she has experienced within the last year v. after an individual indicates on the SRRS which life-changes, and corresponding life-change units, he/she has experienced within the last year, a cumulative score is determined for him/her

vi. interpretation of the individual's cumulative score on the SRRS is as follows: a. 150-199; mild stress b. 200-299; moderate stress c. 300 or over; severe stress C. Stress as a response I. definition of stress as a response a. stress is the non-specific response of the body to any kind of demand made upon it b. focuses on reactions rather than events or individual differences II. stress as a response was developed by Hans Selye (1956, 1976) a. Seyle's view of the non-specific response i. a response to any demand made on the body, also known as a stressor ii. occurs regardless of the cause, situation, or psychological interpretation of the stressor iii. characterized by the same predictable chain or pattern of physiologic events iv. called the General Adaptation Syndrome (GAS), or stress response

v. the GAS results in the release of certain adaptive hormones and subsequent changes in the structure and chemical composition of the body D. Stress as a transaction I. definition of stress as a transaction a. stress is a transaction between the person and an event within a certain environment b. focuses on individual differences, rather than events or reactions II. stress as a transaction view developed by Lazarus (1966) a. concepts important to Lazarus' view of stress as a transaction i. demands a. an event within the internal and external environment confronting an individual ii. primary (cognitive) appraisal of demands a. is the interpretation of a demand by an individual b. individual factors which can influence an individual's primary (cognitive) appraisal of a demand i. his/her depth of feeling about the event ii. his/her beliefs about the event iii. his/her control over the event c. event factors which can influence an individual's primary (cognitive) appraisal of a demand i. unpredictability of the event ii. uncertainty of the event iii. timing of the event iv. duration of the event v. ambiguity of the event iii. secondary appraisal of demands a. assessment by an individual of coping mechanisms available for utilization in adapting to a demand iv. reappraisal of demands a. reevaluation by an individual of the efficacy of coping mechanisms utilized to adapt to a demand b. stress as a transaction view attempts to answer the following: i. which factors lead some persons, and not others, to respond effectively to events within a certain environment ii. why some persons differ in their sensitivity and vulnerability to certain types of events in a certain environment iii. why some persons are able to adapt over longer periods than others to events within a certain environment E. Physiologic manifestations of stress I. GAS a. Stage one (alarm reaction [AR]) i. initial response of the body to a stressor ii. divided into parts (two parts) a. shock phase i. stressor is perceived by the person either consciously or unconsciously ii. autonomic nervous system (ANS) reacts a. readies the person for "fight or flight" iii. lasts from one minute to 24 hours b. countershock phase c. reversal of bodily changes produced in the shock phase b. Stage two (stage of resistance [SR]) i. body attempts to adapt to the stressor a. there is complete reversal of bodily changes produced in Stage one b. there is institution of coping and adaptive mechanisms c. there is confinement of stress to the smallest area possible i. local adaptation syndrome (LAS) a. e.g., inflammation c. Stage three (stage of exhaustion [SE]) i. coping and adaptive mechanisms are exhausted a. two possibilities i. body may rest and mobilize its defenses to return to normal ii. body may reach total exhaustion and die F. Psychologic manifestations of stress I. anxiety a. vague sense of impending doom or apprehension that appears to have no reason b. experienced to some degree by all people c. not always bad i. needed to accomplish developmental tasks ii. needed to motivate goal-directed behavior d. levels of anxiety i. mild a. present in day-to-day living; increases alertness and perceptual fields and motivates learning and growth b. although mild anxiety may interfere with sleep, it also facilitates problem-solving ii. moderate a. narrows the person's perceptual fields so that the focus is on immediate concerns, with inattention to other communications and details iii. severe a. creates a very narrow focus on specific detail; causes all behavior to be geared toward getting relief b. the person has impaired learning ability and is easily distractible iv. panic a. causes the person to lose control and experience dread and terror b. the resulting disorganized state in characterized by increased physical activity, distorted perceptions and relations, and loss of rational thought c. the person is unable to learn, concentrates only on the present situation, and often experiences feelings of impending doom d. can lead to exhaustion and death II. fear a. a mild to severe feeling of apprehension about some perceived threat b. difference between anxiety and fear

i. source of stress a. anxiety = unknown b. fear = known ii. timing a. anxiety = related to the future b. fear = related to the present iii. explicitness a. anxiety = vague b. fear = definite iv. cause a. anxiety = result of psychologic or emotional conflict b. fear = result of a discrete physical or psychologic entity III. coping mechanisms a. in mild level of anxiety i. crying, laughing, sleeping, and cursing ii. physical activity and exercise iii. smoking and drinking iv. lack of eye contact and withdrawal v. limiting relationships to those with similar values and interests b. in moderate, severe, and panic levels of anxiety i. task-oriented reactions a. attack behavior i. occurs when a person attempts to overcome obstacles to attack a problem; may be constructive, with assertive problem-solving, or destructive, with feelings and actions of aggressive anger or hostility

b. withdrawal behavior i. involves physical withdrawal from the threat, or emotional reactions such as admitting defeat, becoming apathetic, or feeling guilty and isolated

c. compromise behavior i. usually constructive; involves the substitution of goals or negotiation to fulfill one's needs partially IV. unconscious ego defense mechanisms a. mental mechanisms which develop as the personality attempts to defend itself, establish compromises among conflicting impulses, and allay inner tensions b. descriptions of unconscious ego defense mechanisms i. compensation a. occurs when a person attempts to overcome a perceived weakness by strengthening other areas b. example i. a short man shows aggressive, dominating traits to suggest strength and authority that his short stature does not convey (the Napoleon complex)
