Q

The Biomedical Model

A

Plato—Mind and body are separate entities
View adopted in 19th century & dominant in medicine today
All diseases can be explained by disturbances in physiological processes (injury, biochemical imbalances, infection)
Disease affects the body
NOT psychological and social processes
Does not account for individual differences in each person

Q

Engel’s Arguments

A

The biomedical approach is reductionist , reducing patients to a sum of physical and medically validated symptoms
“Reductionism is particularly harmful when it neglects the impact of nonbiological circumstances on biological processes” (Holman, 1976)

Variability in clinical expression of a disease, as well as personal experience with a disease, is not fully accounted for by medical markers of the disease
E.g., We can’t tell how diabetes is affecting day to day life just by looking at blood glucose level
Patients can communicate important information about their illness and treatment experience that cannot be gained from medical tests alone.
E.g., Knowing that a patient has a high blood glucose level won’t tell us anything about their ability to reliability take their insulin!
Medical treatment does not always alleviate symptoms, even in the face of biological improvement
Example: The patient who no longer shows objective signs of injury to the knee, but still reports high levels of pain at the injury site.
Physicians who can instill peace of mind into their patients will have patients who:
Are more likely to follow treatment recommendations
Show greater signs of improvement

Q

During stress

A

CRF/CRH (corticotropin releasing hormone): Produced in the hypothalamus and secreted by the paraventricular nucleus (PVN)
Sent to pituitary gland to stimulate release of adrenocorticotropic hormone (ACTH)
Suppresses appetite, increases anxiety, improves selective attention

17
Q

ACTH

A

Follows diurnal rhythm—higher levels in the a.m., declining through the day
Released during times of stress to stimulate cortisol release by the adrenal glands

18
Q

Adrenal Glands

A

Located on top of kidneys

19
Q

Cortisol (corticosteroid)

A

Helps reduce swelling that results from injury (physiological stress)

20
Q

Epinephrine & norepinephrine (catecholamines)

A

Responsible for bodily reactions that prepare the body to confront stress
Increased heart/respiration rate, increased sugar production for quick energy

21
Q

General Adaptation Syndrome (Selye)

A

Body’s response to prolonged stress
Fight or flight
Immediately helpful, but damaging if prolonged
Fight or flight is only the initial response

22
Q

Allostatic Load

A

Accumulated effects of physiological strain due to stress on the body over
Includes hormone, immune system, cardiovascular changes
Negative correlation with health status in children and elderly (Johnston-Brooks et al., 1999)

23
Q

Allostatic Load Influencing Factors

A

Amount of exposure—frequency, intensity, and duration matters
Magnitude of reactivity—individual differences in physiological responses to stress
Rate of recovery—ruminating or worrying prolongs reactivity
Resource restoration—sleep is a major part of restorative process

24
Q

Accumulated Effects Over Time

A

Severe and ongoing childhood stress can change the body’s reactivity over time
Greater stress response (Gilbert et al., 2015)
Slower recovery (McCrory et al., 2015)
Greater risk of illness in adulthood (Miller, Chen, & Parker, 2011)
Higher levels of allostatic load in adulthood (Gruenwald & colleagues, 2012)
Evidence of faster aging processes (Kiecolt-Glaser et al., 2011)

25
Cognitive Appraisal (Lazarus, 1999; Lazarus & Folkman, 1984)
Accounts for individual differences in response to a stressor Primary appraisal Evaluation of the significance of the stressor Is it stressful, challenging, controllable, positive, etc.? What is the expectation for future harm? “How will this affect me?” Harm-loss How much damage has already occurred? Threat What additional damage is likely to occur? Challenge What is the opportunity for achievement or gain?
26
Transactional Relationships Between Stress & Psychosocial Factors
Stress & cognition Memory, attention, concentration Thoughts can produce stress, too Stress & emotion Emotions often are used to evaluate stress Reaction depends on appraisal Fear, anxiety, depression, anger Stress & social behavior Nature of stressor can determine changes in prosocial behavior Aggressive behavior often increases (Child abuse)
27
Some Sex Differences in Stress
Women: Report experiencing more stressors than men Greater strain working outside home & managing household responsibilities Men Higher levels of stress reactivity May be situation-specific (e.g., when competence is challenged) Slower rates of recovery
28
Measuring Stress
Physiological measurements Assessing the body’s level of physiological arousal during stress Blood pressure, heart rate, respiration, galvanic skin response (Polygraph measures all of these!) Assess changes in hormone levels through blood, urine, or saliva analysis Advantages: Objective, quantifiable, and reliable Disadvantages: Affected by gender, weight, caffeine intake; may create arousal; expensive
29
Measuring Stress (2)
Life Events Social Readjustment Rating Scale (Holmes & Rahe, 1967) Self-report of major happenings in life that require some degree of psychological adjustment Strengths & weaknesses?
30
Measuring Stress (3)
Daily Hassles Smaller, day-to-day unpleasant occurrences Hassles Scale (Kanner et al., 1981) Assess hassles experienced and their severity E.g., losing something, stuck in traffic More strongly correlated with health than life events
31
Social Support
Comfort, care, & assistance available from others Everyone’s need is different, and may change depending on circumstances Includes received support & perceived support Tends to decline in chronic stress situations
32
Types of Social Support
Emotional (esteem) support Common type of support—encouragement, empathy, concern Buffers the negative emotional impact of stress Instrumental support—giving direct assistance Meals, money, help with household chores Informational—advice, feedback Companionship—spending time together, providing a sense of belonging
33
Does Social Support Reduce Stress?
Greater levels of social support predict: Lower levels of job stress (Cottington & House, 1987) Lower blood pressure on the job (Karlin et al., 2003) Larger nighttime declines in blood pressure (suggesting better restorative sleep; Troxel et al., 2010) Less physiological reactivity while giving a speech (Uchino & Garvey, 1997)
34
Buffering hypothesis (Cohen & Wills, 1985)
Social support protects people from the negative effects of high stress We appraise and respond to stress in a healthier manner w/better support Statistically, stress and SS interact E.g., During periods of high work stress (but not low stress), support is negatively correlated with blood pressure (Karlin, Brondolo, & Schwartz, 2003
35
Direct effects hypothesis (Cohen & Wills, 1985)
Also called main effects hypothesis Social support has a positive impact on health regardless of severity of stress, likely because social support is related to other positive outcomes that affect stress May have good sense of self-esteem and belonging May lead people to adopt healthier lifestyles Also supported by research data
36
Stress Prevention Model
Uchino & Birmingham, 2011 Social support provides resources to individuals that help to avoid or minimize exposure to stressors E.g., Learning to make good choices, interacting with others in constructive ways to minimize conflict
37
Personal Control
Belief that one can make decisions and take actions to produce desirable outcomes & avoid undesirable ones Behavioral control—Ability to take action Cognitive control—Ability to think differently or in a more positive way Modifies relationship between stress & health Significant individual differences Related to lower perceived stress
38
Locus of Control
Attribution of control over one’s successes and failures Internal: We believe we have control over our success & failure External: We believe our success & failure is largely due to external factors or chance Includes self-efficacy (Bandura, 1986) Our beliefs about our ability to accomplish something Prior successes in an area reinforce future attempts
39
Learned Helplessness (Seligman, 1975)
Attributions about bad events can be Internal vs. external—Is the cause due personal inability or environmental factors? Stable vs. unstable—Is the cause long-lasting or temporary? Global vs. specific—Does it affect many areas or just this one?
40
Rodin & Langer, 1976
Experimental study on the effects of responsibility on personal control and health in a nursing home population Tx Group: Choices re: having/caring for a plant, selecting daily activities, moving furniture Control Group: No choices or responsibilities Results: Tx group participants were happier, more active at the end of study and 1.5 years later Tx group participants were healthier and 50% less likely to die before follow-up
41
Type A and Health
Greater stress reactivity & perception of threat (Glass, 1977) Type A is positively correlated with: Mortality Risk for coronary heart disease (CHD) Angina, atherosclerosis, myocardial infarct (MI; Rosenman et al., 1986) White collar jobs Magnitude of correlation often depends on how Type A is measured
