Biases
37
Reliability vs Validity
Reliability: consistency of a measure
Validity: accuracy of a measure
38
Face Validity
Face: whether the test, on the surface, appears to measure what it is supposed to measure
39
Predictive Validity
Predictive: whether the test predicts some criteria external to the test.
40
Convergent Validity
Convergent: whether a test correlates with other measures that it should correlate with.

From group differences in quasi-experimental designs
45
P-value definition
probability that a difference of that size (or larger) would be found, if the actual size of the difference were zero
46
What is the five step framework for interpreting tables and graphs?
ORIENT yourself

HOW do they differ?
WHERE are the differences?
WHY do they change?
47

the central nervous system
49
What are the structures of the Nervous System?
brain, spinal cord, and nerves throughout the body
50
What is the function of the nervous system?
The cells of the nervous system are the body’s primary communication system
51
How is the nervous system relevant to health psychology?
The nervous system underlies the physiology of stress and pain responses.
52
How many neurons are in the brain?
40 billion
53
What does the peripheral nervous system contain and what two parts is it broken up into?
It contains all nerves in the body
Somatic and Autonomic
54
What does the Somatic nervous system do?
nerves that 1) carry messages from sensory organs (e.g., eyes, ears) to the CNS and 2) from the CNS to muscles and glands
The somatic nervous system is sometimes referred to as the voluntary nervous system, because the skeletal muscles of this system are under voluntary control, such as when we choose to get up and move across the room.
55
What does the autonomic nervous system do?
nerves that link the CNS with the heart, intestines, and other internal organs
The autonomic nervous system is often called the involuntary or automatic nervous system, because it controls the organs over which we do not typically have voluntary control.
56
What two systems is the autonomic nervous system broken up into?
The sympathetic (fight or flight)
The parasympathetic (rest and digest)
57
What are the structures of the endocrine system?
A complex network of glands and organs, especially the pituitary, adrenal, and thyroid glands, and the pancreas
58
What is the function of the endocrine system?
Endocrine glands release hormones (i.e., chemical messengers) into the bloodstream to regulate bodily functions
59
Which system controls slow acting bodily systems?
The endocrine system
60
What is the difference between hormones and neurotransmitters?
Hormones are produced in endocrine glands and are secreted into the bloodstream.
Neurotransmitters: Neurotransmitters are released by presynaptic nerve terminal into the synapse.
Hormones: Hormones are transmitted through blood.
Neurotransmitters: Neurotransmitters are transmitted across the synaptic cleft
61
What is the pituitary gland?
Alongside the hypothalamus, the pituitary gland acts as a master control system of the endocrine system
62
How does the pituitary gland relate to health psychology?
Regulates the amount of the “stress hormone” cortisol that is released by the adrenal gland
63
64
What does the thyroid gland regulate?
growth and the metabolism
65
what does the pancreas regulate?
Blood glucose
66
What are the three types of blood cells and their functions?
Red -- carry oxygen from lungs into the body
White -- immune sysyem
Platelets -- keep us from losing blood when injured
67
Where do arteries carry blood?
From heart to the organs and tissues
68
What is blood pressure?
Blood pressure refers to the force that blood exerts against blood vessel walls (systolic = pressure exerted when the heart contracts to pump blood out; diastolic: pressure exerted when the heart relaxes as blood flows back into the heart).
69
What are the structures of the respiratory system?
The lungs and airways
70
What is the function of the respiratory system?
Enables us to inhale air and exhale carbon dioxide to supply the cardiovascular system with oxygen
71
Digestive System Structures
Digestive/gastrointestinal tract as well as salivary glands, pancreas, liver, gallbladder
72
Digestive System Function
Breaks down food into molecules that can be used for energy, growth, and tissue repair
73
Digestion relation to Health Psychology
A healthy digestive system is important for providing your body with nutrients that support health. When you are in danger or under stress, digestion slows.
74
The Immune System Structures
a network of capillaries, lymph nodes, and ducts, as well as bone marrow, tonsils, spleen, and thymus gland
75
The Immune System Function
Defends the body against antigens that can harm health, such as bacteria, viruses, fungi, parasites, and foreign microorganisms
76
What does the lymphatic system do?
The lymphatic system circulates white blood cells throughout the body to patrol for antigens
77
What expands to cause swelling and inflammation when you are sick?
Lymphocytes
78
What do the lymphatic capillaries carry?
Lymph, a colorless bodily fluid formed by water, proteins, microbes, and other foreign substances that are drained from the spaces between body cells
79
What do lymph nodes contain?
Lymph nodes contain filters that capture infectious substances and debris, and then lymphocytes destroy those foreign particles.
80
What does inflammation do?
Inflammation isolates injured tissues, mobilizes the immune response, and promotes healing
81
Genotype
all the genes that a person inherits
82
Phenotype
observable characteristics of a person
83
What is DNA Methylation?
DNA methylation is a chemical process that adds methyl groups to DNA, which can alter gene expression and regulate protein production:
84
When does methylation begin?
Methylation begins before birth and continues across the lifespan, altering how genes are expressed in response to environmental events even after we are born.
85
How does DNA methylation relate to asthma?
DNA methylation seems to be one of the biological mechanisms responsible for the development of asthma in children who are exposed to air pollution at a young age. DNA methylation may also explain the effects of early life stress on increased vulnerability for later depression.
86
What is the difference between a health disparities and health differences?
Health disparities are not just health differences between groups
Health disparities are preventable
Health disparities are due to social injustices
87
Disparity or Difference: Incidence of skin cancer is higher among White U.S. Americans
Difference
88
Intersectionality Theory
Intersectionality is a sociological analytical framework for understanding how groups' and individuals' social and political identities result in unique combinations of discrimination and privilege.
89
What are the three goals of health disparities research?
1. To document patterns of health disparities
2. To understand how and why they exist
3. To identify ways to reduce disparities and promote health equity through science, policy, and practice.
90
Equality Definition
Everyone gets the same resources regardless of social position --> equal resources but not necessarily equal outcomes
91
Equity Definition
People get different levels of resources depending on need --> NOT equal resources, but achieving equal OUTCOMES
92
Justice Definition
Removing the fundamental barriers that are leading to the disparities in the first place --> allocation of resources becomes irrelevant / unnecessary
93
What does the national institute of aging do?
Federal agency that awards researchers grant money to advance the scientific study of health and aging, including health disparities across the lifespan
94
What is minority stress theory?
An additional layer of stress that uniquely impacts LGBTQ individuals’ health
Suggests that engagement in risky health behaviors is not necessarily due to individual-level factors
Rather: discrimination, victimization, and harassment that result from heterosexism, cisgenderism, homophobia, and transphoboia directly impact LGBTQ people’s engagement in risky health behaviors, as well as mental and physical health
95
Are minority stressors chronic?
Yes
96
Are minority stressors socially-based?
Yes
97
How does maslow's hierarchy of nees relate to health equity?
It can help explain how sociocultural disadvantage prevents individuals from engaging in certain behaviors and from achieving their full potential
With threats of safety and physiological needs, it is easier to ignore one’s higher-levels needs because the basic ones are jeopardized
98
What is the gender paradox?
Women have greater morbidity (disease-burden) than men, but lower risk of mortality (death) than men
Ie: Men experience more life-threatening chronic diseases and die younger, whereas women live longer but have more nonfatal chronic conditions and disability
99
The Immigrant Paradox
Observation that immigrants are “healthier” compared to US-born peers of similar demographic and socioeconomic profiles
100
What are 4 possible explanations for the Immigrant Paradox?
1. Cultural and Behavioral Factors
2. Migrant Selectivity
3. Return Migration Selectivity
4. Data Artifacts
101
What does data artifacts mean?
Immigrants are less likely to participate in major surveys of health for fear of outing themselves; only the healthiest immigrants participate in large-scale surveys documenting health differences between immigrants and non-immigrants
102
Confirmation Bias
a tendency to pay attention only to evidence that confirms what we already believe.
103
Epidemiology
A field that seeks to determine the frequency, distribution, and cause of a particular disease or other health outcome in a population.
104
Disease Vector
Any agent which carries and transmits an infectious pathogen into another living organism.
105
Morbidity
The number of cases of a specific illness, injury, or disability in a given group of people at a given time
106
Mortality
The number of deaths due to a specific cause, such as heart disease, in a given group at a given time
107
3 Fundamental Objectives of an Epidemiologist
1. Identify the origin of a particular disease to generate hypotheses
2. Evaluate the hypotheses
3. Test the hypotheses
108
Prospective Studies
Take a group of disease-free participants and follows them over a period of time to determine whether a certain condition or behavior is related to a later health condition.
109
What does a relative risk of 1 mean?
There is no difference in risk between the two groups
110
What does a relative risk score above/below 1 mean?
A relative risk above 1.0 indicates there is a positive association (the exposed group has a greater risk).
A relative risk below 1.0 means the incidence or prevalence rate of the exposed group is less than that of the not exposed group
111
What are the two types of tissues?
Epithelial and Connective Tissues
112
What are epithelial tissues?
Epithelial tissues are sheets of closely packed cells covering body organs and other surfaces.
They also form glands that secrete hormones, breast milk, etc.
113
What are connective tissues?
Connective tissues are made up of more widely separated cells that bind together and support organs and other body tissues
Bone, cartilage, and tendons are types of connective tissues
114
Which two body parts work together to act as the master control system?
The hypothalamus and pituitary gland
115
Self Other Agreement
the degree to which self and informant reports agree
116
