Health psychology involves what
> Promotion and maintenance of health
Prevention and treatment of illness
Identification of etiologic and diagnostic correlates of health, illness, and related dysfunction
What is the field of Behavioural medicine?
> Interdisciplinary field
Concerned with health, illness, and related dysfunction
What are three subspecialties of health psychology?

2) Occupational health psychology
3) Community health psychology
What is clinical psychology?
> Addresses management of symptoms and psychological consequences of symptoms
What is occupational health psychology
> Addresses prevention and management of occupational stress
What is community healthy psychology?
> Addresses community-wide health needs and health-care systems
What is a Brief History of Health Psychology in Ancient Greece?
> Indoctrained by Hippocrates and Galen
They had a Holistic view of health
Believed that the mind and the body were part of the same system
they thought that a balance between physical and emotional states was necessary to sustain overall health
What is cartesian dualism? Who invented it?
> René Descartes
Mind and body are separate entities; explanations for illness can be found in the body alone
The basis for much of physical medicine in Western societies
What did Psychosomatic medicine initially focus on and what does it emphasize?
> Initially focused on illness behaviour that could be attributed to psychological causes
> Emphasized etiology and pathogenesis of physical disease
Who are some Key figures in psychosomatic medicine
> Johann Christian August Heinroth: coined the term psychosomatic medicence
> Benjamin Rush: father of modern psychiatry
> Sigmund Freud: believed that certain symptoms represented manifestations of unconscious conflicts
> Franz Alexander: physical disease can be the result of “fundamental, nuclear, or psychological conflict”
> Helen Flanders Dunbar: founding editor of Journal of Psychosomatic Medicine
> Guze, Matarazzo, and Saslow: invented the biopsychosocial model

> The biopsychosocial model
Health belief model
Social cognitive theory
Theory of planned behaviour
The common-sense model of self-regulation/illness representation
Cognitive behavioural perspective
The transtheoretical model of behaviour change
What is The Biopsychosocial Model?
> Forms the conceptual basis of health psychology
> Considers the interplay and integration of biological, psychological, and social factors on health
> Contrasts with the medical model of disease, which separates the physical and psychosocial
Readiness to take action in relation to health problems is a function of what two factors under the health belief model?
- Beliefs about health condition (e.g., perceived severity, perceived risk, perceived barriers to action)
- Perception of the benefits of taking action to prevent health problems
> Factors that may affect these types of beliefs (e.g., demographic variables) are considered
What are individual perceptions under the health belief model
> perceived susceptibility
perceived severity
perceived benefits of preventative action
perceived barriers to prevent action
What are modifying factors under the health belief model?
> demographic variables
socio-psychological variables
What increases the likelihood of taking recommended preventive health action?
> percieved threat
What are cues to action under the health belief model?
> information
reminders
persuasive communication
experience
What is social cognitive theory?
> Based on the work of Albert Bandura
> Human behaviour is reflected in three-way model:
1) Interaction of personal factors
2) Environmental influences
3) Behaviour
What are 4 central constructs to social cognitive theory?
Reinforcement, observational learning, self-control, self-efficacy
What is the theory of planned behaviour
Believes that Behaviour is determined by three beliefs:
- Behavioural beliefs—Lead to favourable/ unfavourable attitudes
- Normative beliefs—Lead to perceived social pressure related to subjective norm
- Control beliefs—Lead to a perception of behavioural control
What is The Common-Sense Model of Self-Regulation
> Describes the way people process and cope with health threats
> Individuals form a lay view of their health based on various sources of information; this guides their coping responses
> There is continuous feedback between the efficacy of how people cope with health threats and their perceptions of the health threat
What is the Cognitive Behavioural Perspective?
> Thoughts, behaviour, and emotions are interconnected and thus our behaviours and emotions also influence our thoughts
> Different people with the same health condition may show different emotional responses to their health
> Cognitive behavioural therapy
What are the stages of The Transtheoretical Model of Behaviour Change?
- Precontemplation
- Contemplation
- Preparation
- Action
- Maintenance
- Termination
What are the body systems?
- Cardiovascular system
- Gastrointestinal system
- Respiratory system
- Renal system/urinary system
- Immune system
What is the cardiovascular system?
> The heart maintains blood flow through a system of outgoing/incoming “pipes” (i.e., arteries, capillaries, and veins)
> Death of heart muscle cells due to myocardial infarction can produce various forms of fibrillation
> Myocardial infarctions are generally the result of atherosclerosis
How does the cardiovascular system work?
> Blood from venous circulation collects in right atrium → ejected into right ventricle
> Blood passed through lungs collects in left atrium → ejected into left ventricle
> Simultaneous contraction of right and left ventricles sends blood out to the lungs and the rest of the body via the aorta
What does the digestive system do, how is the process monitored, and what does the involvement of muscle activity suggest?
> Digestion transforms food to a form where nutrients can be easily absorbed
> The process is monitored locally and by the brain
> The involvement of muscle activity throughout the process suggests a possible means of disruption and a mechanism for functional gastrointestinal disorders that some experience during stress
Where does the digestive system begin?
> Breakdown begins in mouth
> Muscle contractions move mixture through esophagus to stomach
> Smooth muscle in the stomach contracts, mixing food with corrosive substances
> Materials from liver and pancreas added in small intestine
> Waste materials proceed through large intestine
What are the primary organs of the respiratory system, what element is required, what is a waste product of this system, and what monitors this system?
> Primary organs are the lungs
- Others include nose, mouth, trachea, diaphragm
> Oxygen is required to convert glucose into adenosine triphosphate, which powers the body’s chemical reactions
- Waste product is carbon dioxide
> Brain monitors chemical composition of the blood and can speed or slow respiration
How does the respiratory system work?
> Air passes into lungs
> At end of the trachea, pathway divides into two bronchi, one for each lung
> Carbon dioxide–rich blood pumped through lungs by heart’s right ventricle
> Carbon dioxide diffuses out into alveoli; oxygen from inspired air is absorbed and proceeds to left atrium for circulation to rest of body
How are the kidneys the main component for The Renal System/Urinary System?
> Kidneys are the main component
- Remove waste products from the blood
- Concentrate urine
- Regulate blood pressure
- Control retention/excretion of electrolytes
What does the immune system entail?
> Protects the body from infection
Process of detection is not perfect
More diverse and much less compartmentalized than other systems
> Primary components are individual cells that circulate in the bloodstream
> Fixed components also exist (i.e., lymph vessels and nodes, thymus and spleen)
What are some components from the Immune System, cont’d
> Circulating leukocytes (i.e., white blood cells) develop from stem cells located in bone marrow
-Contains Myeloid and lymphoid types
> Cells from myeloid line as well as some from lymphoid line provide “non-specific” immunity
- Pre-programmed to attack common invaders
> “Specific” immune cells derived from lymphoid line are more flexible
- Respond to protein patterns on new threats
Psychological Influences on Body Systems - how is physiology and behaviour adjusted?
> Nervous systems process information about the environment and internal condition of the body
- Adjust physiology and behaviour accordingly
> Physiological activity is also adjusted according to internal/external sensory information
The Peripheral Nervous System - where are neurons located for it, what does it allow the body to do, and what are the two subsystems of the body?
> Neurons are located outside the central nervous system (CNS)
> Allows the brain to make quick adjustments of body function
> Two subsystems:
Somatic nervous system
Autonomic nervous system (ANS)
What is The Autonomic Nervous System and what does it overall influence? How do the SNS and the PNS affect this system?
> Influences “involuntary” muscle activity
- Sympathetic nervous system (SNS)
Stimulates smooth muscle activity - Parasympathetic nervous system (PNS)
Usually inhibits smooth muscle activity
How does the endocrine system work?
> The brain can influence body function by stimulating the release of hormones
> Effects of hormones complement and extend peripheral nervous system activity
> Especially hormones released from the central portion of the adrenal glands
> Most hormones are controlled by the hypothalamus and pituitary gland
What was Walter Cannon’s take on stress?
> Walter Cannon
- “Fight-or-flight response pattern”
- SNS allows the brain to prepare the body for a potentially life-threatening situation
What did Hans Seyle believe about stress?
> A wide range of stimuli can elicit a pattern of physiological activity (“stress response”)
> Effects of stress on hormonal activity (specifically, adrenal hormone cortisol)
How are emotions and stress linked?
> link between emotion and stress
> Emotions often elicit stress reactions
> Stress response is tailored to the situation
- Anger vs. fear
> Stress response does not require actual exposure to a challenging situation
- Anticipation or memory of an event is enough
Psychological Factors in the Development of Illnesses- what is a common example?
> Gastrointestinal ulcers
- “Executive monkey” experiment
- More likely to occur in situations involving long-term uncontrollable stress, hopelessness, and depression
What are vasovagal reactions? What is it an example of?
> Dizziness, weakness, fainting
More likely to occur in situations of short-term uncontrollable stress
Possibly developed as a response to the anticipation of pain and/or blood loss
> Psychological Factors in the Development of Illnesses
What is high blood pressure formally known as and what emotions are linked to it?
> High blood pressure
Hypertension
> Theories focus on situations and emotions related to struggle, aggression, and anger
What diseases are linked to cortisol?
> Coronary heart disease, obesity, impaired central nervous system function
- Cortisol
What is the Most important development in health psychology in the last 20 years?
> Psychoneuroimmunology
Who coined the term “psychoneuroimmunology”?
> Ader
Demonstrated that aspects of immune system function can be influenced by classical conditioning
How did Hans Selye contribute to the Psychoneuroimmunology field?
> found Connections among stress, cortisol, immune function, and ulcers
Stress and susceptibility to illness has been found with what?
> common colds, AIDS, cancer
What has stress reduction interventions been used for?
Effects of stress reduction interventions on the progression of serious illness
What does stress involve?
> Stress involves some perturbation of the system in response to perceived threat or demand
The study of the body’s response to stress was largely launched by two theories:
Fight-or-flight response (Cannon, 1929)
General Adaptation Syndrome (Selye, 1976)
What is distress and what health outcomes are associated with it?
> Distress: Feeling of having insufficient resources to meet demands of a situation
- Negative health consequences
What is eustress and what health outcomes are associated with it? What notion is it connected to?
> Eustress: Confronting challenges one can adequately deal with
> Positive health consequences
Connected to notion of optimal arousal
Does stress still remain without the presence of a stressor?
> Impact of stress will persist even after stress has passed
Difference between stressors could be what?
> could be how many times they recur and how long they last
What process turns acute stressors into chronic stressors?
> can turn acute stressors into chronic ones

Job and Primary Role Stress what does that involve?
> Job demands and amount of autonomy
Effort–reward imbalance
job demands vs capabilities of employee
What is the Social Readjustment Rating Scale (SRRS)? What does it not distinguish and what has been found from it?
> quantifies the general level of stress in a person’s life
> Does not distinguish between positive and negative events
> quantifies the general level of stress in a person’s life
Does not distinguish between positive and negative events
The caretaker’s role is exemplified by what factors?
> by relentless responsibility, vigilance, and hassles
What specific negative health outcome is associated with caregiving?
> Can reduce telomere length (marker of cellular aging)
Sociological Stress: SES, Gender, Race- how are women affected?
> Dual roles for women in the workforce
- creates role conflict + stress
Low SES leads to what health outcomes?
> poor nutrition, smoking
Racial bias
Poor physical health
Personality dimensions of stress-prone people: what are some of them?
> Type A personality
- Anger, hostility, and aggression
> Negative affectivity (NA)
- Prone to negative emotions (e.g., anger, fear, disgust, contempt, etc.)
Effort–distress model - how are events seen in this model?
> are seen as excessive/out of control
Stressfulness of SES might be the combination of what?
> available resources and the ways individuals use them
> i.e., being poor AND living beyond one’s means
Stress also depends on the particulars of the person and the situation- what occupation was found to be affected by the particulars of the person?
> Traffic enforcement agents: hostile interactions + hostile personality = high levels of stress
What is a primary and secondary appraisal?
> Primary appraisal: Determination of the magnitude and nature of the threat
> Secondary appraisal: Determination of the resources available to deal with the threat
What is problem focused coping?
> Directly addressing the demands of a situation
What is emotion focused coping?
> Addressing the emotions that come with stressful situations
What is avoidant focused coping?
> Ignoring the problem and resulting emotions
In the Ways of Coping Scale (Folkman et al.), what are the different types of coping?
1) Confrontative coping
- “I tried to get the person to change his/her mind”
2) Distancing
- “I went on as if nothing had happened”
3) Self-controlling
- “I tried not to act too hastily”
4) Seeking social support
- “I talked to someone about how I was feeling”
5) Accepting responsibility
- “I realized I brought the problem on myself ”
6) Escape-avoidance
- “I slept more than usual”
7) Planful problem-solving
- “I made a plan of action and followed it”
8) Positive reappraisal
“I changed something about myself”
What is social support?
a social network in which others care about one’s well-being and provide help and assistance.
Help is generally divided into four categories for social support:
1) Emotional
2) Instrumental
3) Informational
4) Appraisal support
What is the main effects model?
> Social support is generally beneficial to health and well-being (whether we are carefree or stress-ridden)
What is the buffering model?
> Social support reduces stress and its negative effects on one’s health
Women are more likely do what with social support compared to men?
> are more likely to seek social support than men
What is the gender difference between the Tend-and-befriend vs. fight-or-flight?
> From an evolutionary perspective, women are physically smaller and weaker, and are often pregnant or caring for small children—a fight-or-flight response is not feasible
Women may have a modified stress response due to what hormone?
> the hormone oxytocin
- Encourages affiliation and caregiving
What is emotional disclosure?
> there may be benefits in “discussing” a problem with oneself (e.g., journaling)
How does exercise impact stress?
> Research shows that people who exercise frequently tend to report lower levels of stress, bore studies are needed to explain why
Stress is a major risk factor for what two psychological disorders?
> for depression and anxiety disorders
what is PTSD?
> Intrusive thoughts, often even when sleeping, of the traumatic event, and this rumination extends the duration of the stressor and multiplies its impact
What is rumination and what is it predictive of?
> fixating and dwelling on events that might be considered minor
- Predictive of future anxiety and depression
- Can make depression worse
Stress and Sleep- what factors impact sleep?
> stress and sleep have a Bidirectional relationship
Job-related stress - interferes with sleep
Digital media use = more stress
Shift-work - interferes with sleep
