1. Which of the following BEST defines epidemiology?
A) The study of disease treatment in individual patients
B) The study of disease distribution and determinants in
populations
C) The laboratory analysis of pathogens
D) The clinical diagnosis of infectious diseases
Answer: B
Rationale: Epidemiology is concerned with disease prevention
and the succession of events resulting in exposure of specific
types of individuals to specific types of environments.
Epidemiologists identify exposures and evaluate associations with
health, welfare, productivity, and other outcomes of interest .
2. What is the primary difference between epidemiologists and
laboratory scientists?
A) Epidemiologists only study infectious diseases
B) Epidemiologists study health outcomes in the real world under
field conditions
1
,C) Laboratory scientists do not study disease causation
D) There is no significant difference
Answer: B
Rationale: Epidemiologists study health and disease outcomes in
the real world (under field conditions), whereas laboratory
scientists typically study disease mechanisms under controlled
experimental conditions .
3. What is the primary study design of epidemiology?
A) Experimental
B) Observational
C) Retrospective only
D) Prospective only
Answer: B
Rationale: The primary study design of epidemiology is
observational. Epidemiologists observe natural occurrences of
disease and exposure in populations rather than manipulating
variables experimentally .
4. Inductive reasoning in epidemiology refers to:
A) Drawing specific conclusions from general principles
B) Making generalized inferences about causation based on
repeated observations
2
,C) Testing hypotheses through controlled experiments
D) Applying statistical tests to data
Answer: B
Rationale: Inductive reasoning is the process of making
generalized inferences about causation based on repeated
observations. This is fundamental to developing epidemiological
hypotheses from observed patterns .
5. Deductive reasoning in epidemiology refers to:
A) Inferring that a general law of nature exists and has
application in a specific instance
B) Making observations and drawing general conclusions
C) Collecting data without a hypothesis
D) Applying statistical models
Answer: A
Rationale: Deductive reasoning is the process of inferring that a
general law of nature exists and has application in a specific or
local instance, where a hypothesis about a law of nature starts
and observations are made to challenge the law .
6. According to the component-cause model developed by
Rothman, a necessary cause is:
A) A factor that always produces disease when present
3
, B) A factor without which the disease CANNOT occur
C) One of several factors that combine to cause disease
D) A factor that increases disease risk
Answer: B
Rationale: In the component-cause model, a necessary cause is
one without which the disease CANNOT occur—the factor will
ALWAYS be present if the disease occurs. An example is
exposure to the rabies virus for rabies to develop .
7. A sufficient cause, according to the component-cause model, is:
A) A factor that must be present for disease to occur
B) A factor that ALWAYS produces the disease when present
C) One of several contributing factors
D) A factor that is neither necessary nor sufficient
Answer: B
Rationale: A sufficient cause always produces the disease—if
the factor is present, disease will follow. Most diseases do not
have a single sufficient cause; rather, they result from
combinations of component causes .
8. A component-cause in the Rothman model is:
A) The only cause of disease
B) One of a number of factors that in COMBINATION constitute a
