more likely to exercise if

-if the form of exercise is convenient and enjoyable -attitudes favor exercise -they come from families in which exercise is practiced

Biopsychosocial Model

-illness caused by a combination of biological, psychological, and social factors -should be treated with changes in behaviors, thoughts, and beliefs of overall treatment -patient partly responsible for treatment -health and illness lie on a continuum that varies by degree -the mind and body interact, each influencing each other -direct psychological factors, such as behaviors, can contribute to illness

best predictor of success is _________________.

the patient

Chronic illness

(especially heart disease, cancer, and respiratory disease) are main contributor to disability and death, particularly in industrialized countries

Relative risk

- RR = [a/(a + b)] / [c/(c + d)] -The relative risk or risk ratio is the ratio of the probability of an outcome in an exposed group to the probability of an outcome in an unexposed group. It is computed as, where is the incidence in the exposed group, and is the incidence in the unexposed group

Which of the following statements about coping are true?

-Providing social support has health benefits. -There is likely a genetic component related to the ability to establish supportive networks.

Which of the following issues would health psychologists be *most* likely to address? (Check all that apply.)

-The influence of peers on a healthy diet. -Improvement of the health care system. -Helping adults to maintain an exercise program.

Which of the following statements would Sapolsky endorse?

-The same stress-response is turned on during every stressor experienced. -If you repeatedly turn on the stress-response, it can become damaging.

Which one of the following statements is/are NOT accurate regarding current screening recommendations? (mark all that apply)

-Yearly mammograms are recommended for women from age 30-60. -Men without symptoms or a family history of prostate cancer should have a routine PSA every other year.

Nocebo effect

-adverse effects caused by a placebo (when people led to believe that tx could worsen symptoms, nocebo effect can be as strong as placebo effect) -occurs on both physical and psychological basis

Which of the following characteristics places an individual at risk for poorer coping and/or greater likelihood of negative health outcomes due to stress?

-being elderly -unemployed -low self-esteem -limited social relationships -working long hours

alcohol and smoking similarities

-both contribute to negative health outcomes (e.g., memory loss, liver disease) -both affect others, not just user (second-hand smoke, drunk driving accidents, inflict pain on innocent people)

Holmes & Rahe: Stressful Life Events

-created inventory of stressful life events based on the amount of change those events cause -people who experience a lot of stressful events are most vulnerable to illness -scores on life event inventories predict illness, but relation is quite modest

Double-blind design (both research and participants unaware of placebo's presence)

-creates ethical dilemmas -usually single-blind designs used, but control for expectancy not as complete -remedy: informed consent

affects of minor hassles on health

-cumulative impact of small stressors may wear a person down, leading to illness -such events may aggravate reactions to major life events or chronic stress to produce distress or illness

Which of the following are positive effects of both regular exercise AND a healthy diet? (Check all that apply but only check if the answer choice is a benefit of BOTH exercise and a healthy diet)

-decreased risk of cardiovascular disease -decreased risk of Type II diabetes -decreased risk of some cancers

Health Psychologist Tasks

-develop theories -research on interaction of biological, psychosocial, and social factors in producing health and illness -help treat patients -conduct counseling for psychosocial problems that illness may create -develop work site interventions to improve employees' health habits -medical settings to improve health and healthcare delivery

Biomedical Model

-disease comes from outside the body and causes physical changes -individual not responsible for illness and has no control over external causes of disease -illness should be treated with medicine, vaccines, surgery, radiation therapy, chemotherapy -medical professional responsible for treatment -health and illness are qualitatively different states -mind and body are separate entities, unable to influence each other as in traditional dualistic model -illness may result in psychological problems, but cannot be a result of psychological factors

Determining causation without experimental studies

-ex: can't make some people smoke and some not for experiment to prove that smoking causes diseases and poor health outcomes -make inferences based on dose-response (curve) relationship (not just for pharm., but applies to behaviors that affect disease processes) - there is a threshold below which no effect observed and an incremental increase in effect as dose increases

health-enhancing behaviors

-exercise (lowers heart rate), diet (modifies cholesterol), sleep (enhances efficacy of flu shot) - enhance daily functioning and lead to lasting good health -all 3 play a role in cardiovascular disease, type 2 diabetes, and hypertension

Experimental design

-gold standard of research because it allows researcher to interpret the cause -if it's unethical for a researcher to manipulate an independent variable, then an ex post facto design can be used (eliminates researcher manipulation -more so observation - and causal relationship cannot be identified as it could be in an experiment; can only observe associations (correlations) between variables

Why Dieting Doesn't Work (TED Talk)

-hypothalamus controls set point for weight (+/- 10-15 lbs.) -hunger and energy use controlled by brain without awareness -works like thermostat to keep weight stable as environment changes - resistance makes evolutionary sense -successful dieting doesn't lower set point -changing food environment = most effective solution for obesity -typical dieting outcome is weight gain -SOLUTION: mindful eating - eat when hungry and stop when full --> preventing weight gain instead of promoting weight loss

Epidemiology Research

-if trials fail to show effectiveness, researchers three times less likely to publish

Placebo

-inactive substance or condition that has the appearance of an active tx, and that may cause people to improve or change because of their belief in placebo's efficacy -patient's beliefs about tx rather than tx itself that provides benefits -complicates job of researchers because hard to tell what is result of tx and placebo -can lead to noticeable improvements in health outcomes, especially in cases of pain and nausea -likelihood of improvement largely attributable to the type of pain experienced -the more a placebo resembles the real tx, the stronger the placebo effect -physician and patient expectations strengthen the placebo effect -placebo effects not merely improvement but includes any change resulting from an inert tx (e.g., nocebo effect) -occurs on both physical and psychological basis -tribute to ability of humans to heal themselves

Mark all of the indicators of allostatic load.

-lowered heart rate variability -problems with memory

Neural communication

-nerves communicate using neurotransmitters (chemicals located in synaptic vesicles until released), travel through synaptic cleft, and attach to receptors in postsynaptic neuron -->when enough neurotransmitter received, it fires (electrical charge passed down length of neuron until it reaches presynaptic terminal) -ex: norepinephrine (sympathetic nervous system)

Brain Structures associated with stress

-nervous system: central and peripheral (CNS and PNS)

Oxytocin

-part of the stress response - motivates you to seek support -role: protect cardiovascular system from stress; helps cardiovascular cells regenerate from any damage and strengthens the heart -enhanced by social support or by supporting someone else -recovery from stress is faster by mechanisms of human connection because caring for others creates resilience

Issues With Research (TED Talk)

-publication bias - unflattering data is lost, not published -provides biased sample of the truth of all research because publication is selective ("freaks get published, not failures") -> need to make it easier to publish negative results -misleading because doesn't give full picture -based on marketing approval -about half of all trials are buried -publication bias affects all fields of medicine -positive findings are twice as likely to be published -research misconduct, research fraud --->suffered fake fixes of this phenomenon -can't know the true effects of meds we prescribe if we don't have access to all information -need to force people to publish ALL trials (not just after 2008 as ordered by FDA) SOLUTION: 1. Publish all trials in humans, including older trials, for all drugs in current use 2. Tell everyone about this problem

Social support has an effect on health, both through its impact on health behaviors and its direct impact on physiological functioning. According to Taylor, which of the following effects are associated with social support?

-reduced physiological and neuroendocrine responses to stress -reduced activation in neural systems related to threat responses -better adherence to medical regimens

Epidemiological research

-same as research methods used in psych., and same caveats apply -results reported in terms of relative risk is most common

Longitudinal research

-same people are observed at multiple points in time -best way to find out how people change over time -disadvantages: takes a lot of time and funding, many participants drop out or can't be contacted, which leads to data loss

Theory

-set of analytical statements that explain a set of phenomena -a set of related assumptions that allow scientists to use logical deductive reasoning to formulate testable hypotheses; should generate research (descriptive and experimental), organize and explain observations derived from research and make them intelligible, serve as a guide to action (permitting practitioner to predict behavior to implement strategies to change behavior)

Dunbar & Alexander

-shaped emerging field by offering profiles of particular disorders believe to be psychosomatic in origin (i.e., caused by emotional conflict) - Ex: ulcers, hyperthyroidism, rheumatoid arthritis, hypertension, neurodermatitis, colitis, bronchial asthma

Obesity, Anorexia, and Bulimia

-these patterns of disordered eating have similar determinants such as genetics and stress, low SES (obesity in American women), perfectionism (anorexia),. hormonal dysfunction (bulimia) -treatment: ---behavioral approaches (e.g., food monitoring, positive reinforcement) effective for all 3 ---food diaries for obesity and bulimia ---interventions for anorexia and bulimia similar in that they both may involve psychotherapy ---meeting with a psychologist to discuss maintaining lifestyle changes for obesity

Tarahumara Tribe

-unchanged tribe in Copper Canyons -evolved as hunting pack animals -can run far without overheating (no other animals can do) = our only advantage -get rid of all packaging, sales, marketing and restore sense of playfulness, joyfulness, and nakedness to restore natural ability of running again

It was found that ice cream sales decrease significantly as the temperature outside decreases; a very strong relationship was found. What is the most likely correlation coefficient from this hypothetical study?

0.80

Risk Factor Approach

1. Absolute Risk - persons chances of developing a disease or disorder independent of any risk other people may have for this disorder (small chances usually) 2. Relative Risk - ratio of incidence (or prevalence) of a disease in an exposed group to the incidence of that disease in an unexposed group

Order of ideas that led to biopsychosocial model of health and illness

1. Illness was thought to be the result of evil spirits 2. Greeks identified role of bodily functioning in health and illness such as the four humours 3. Church asserts that disease is God's punishment 4. The biomedical model emerged, asserting that illness was caused soley by bodily processes. 5. Freud's work with conversion hysteria provides a mind/body link. 6. Dunbar and Alexandar's work influenced the field of psychosomatic medicine which asserts that some disorders are the result of emotional difficulties. 7. biopsycosocial model emerged which assumes that a balance of health and illness relies on an interaction between

How does social support moderate effects of stress? 2 possibilities:

1. direct effects hypothesis - social support is generally. beneficial during nonstressful as well as stressful times 2. buffering hypothesis - physical and mental health benefits of social support are chiefly evident during periods of high stress; when there is little stress, social support offers few such benefits

Epidemiology Causal Relationship Criteria

1. dose-response relationship must exist (direct, consistent association between an independent variable, such as behavior, and a dependent variable, such as disease) 2. prevalence or incidence of disease should decline with removal of possible cause 3. cause must precede the disease 4. cause and effect relationship between the condition and the disease must be plausible (consistent with other data) 5. relevant research data consistently reveal a relationship between the condition and the disease (research findings must be consistent) 6. strength of association between condition and disease must be relatively high 7. existence of appropriately designed studies

SAM Stress Response

1. higher brain centers STIMULATE HYPOTHALAMUS (sometimes consciously aware of stimulus, sometimes not) 2. nerves of sympathetic nervous system are stimulated by the hypothalamus. NOREPINEPHRINE RELEASED AND AFFECT TARGET ORGANS (heart, blood vessels, stomach, including adrenal medulla) 3. EPINEPHRINE AND NOREPINEPHRINE (hormones) circulate through bloodstream and affect target organs in same way as the direct influence of sympathetic nerves

HPA-axis Stress Response

1. higher brain centers stimulate hypothalamus 2. hypothalamus releases CRH 3. CRH flows into anterior pituitary gland and stimulates release of ACTH 4. ACTH flows into bloodstream and reaches adrenal cortex (outer edge of adrenal glands), which releases hormones called glucocorticoids (mostly cortisol) into bloodstream, which increases circulating glucose, amino acids, and fatty acids, increases BP and heart rate, and mobilizes energy from muscle and bone 5. cortisol "feeds back" to stimulate hypothalamus to release less CRH and ACTH ---> in this way, body regulates cortisol levels to keep them from getting too high = negative feedback loop

Epidemiology research methods

1. observational studies (similar to correlational) -reveals association between variables but not cause -a) retrospective studies - done with a group that already has disease vs. healthy control (disadvantage: relying on people's recollection of past behaviors) -b) prospective studies - follows group of people over time (same as longitudinal) 2. Randomized controlled trials

Connections between CNS and PNS

1. sensory info. comes in from environment through thalamus 2. signals travel to other parts of the brain, including hypothalamus, which detects and controls the internal state of the body, including release of hormones 3. hypothalamus sends signals to autonomic nervous system, which controls automatic functions like blood pressure, heart rate, digestion, etc. 4. other structures involved in the stress response include the amygdala, which is associated with anger and fear, and the hippocampus, which is associated with memory processing

2 branches of stress response

1. sympathetic - adrenal-medullary response (SAM) 2. hypothalamic-pituitary-adrenal-cortical response (HPAC) or HPA-axis

Secondary appraisal

determining if we have the necessary means to deal with the event (e.g., social support system, self confidence)

Cross-sectional studies

developed to approximate longitudinal study because people only measured once, and all during the same time period so it solves longitudinal drawbacks -disadvantages: interpretation of results is compromised by the fact that a comparison is made across different individuals when research question is asking how individuals compare to themselves over time

evidence-based medicine

medical and psychological interventions go through rigorous testing and evaluation of their benefits, usually through randomized clinical trials, before they become the standard of care

Transtheoretical model of behavior change

model that analyzes the stages and processes people go through in bringing about change in behavior and suggested treatment goals and interventions for each stage: precontemplation stage (no intention of changing), contemplation (aware that theres a problem), preparation (intentions to change behavior but haven't yet successfully), action (modify behavior to overcome the problem), maintenance (work to prevent relapse and to consolidate gains) -->Spiral model of changes
