Week 4 Epidemiologic Study Design Quiz

To show
causality, researchers must use a/an ______________ study design.

Experimental

Observational

Cohort

Case-control

Cross-sectional

2The Texas
Men’s Health Study enrolled 38,649 men in 1999 and collected exposure and
lifestyle information to assess the relationship between these factors and
subsequent occurrence of heart disease, is an example of which type of study?

Experimental study

Observational study

Cohort study

Case study

Cross-sectional study

3Clinical
trials occur under very specialized, controlled conditions that do not
represent everyday life. Generalizing the results obtained in this environment
to populations not engaged in the research is a concern for this type of study.

True
False

4Suppose
you want to know the effects of cocaine use by pregnant women on their babies.
What would be the most appropriate method for studying this?

Experimental

Observational

Cohort

Case-control

Cross-sectional

5What study
design is very useful for rare diseases that require many years to develop and
many people to observe?

Experimental

Observational

Cohort

Case-control

Cross-sectional

6Surveys
are not very good at capturing practices and health conditions of populations.

True
False

7A study
design that involves measuring the same participants over some period of time
is a_________ study.

Cross-sectional

Quasi-developmental

Experimental

Cohort

Case-control

8Compared
to cohort studies, case-control studies are __________ and _________ to do.

Hard/fast

Well-organized/difficult

Conceptual/hard

Fast/cheap

9A study in
which adults are randomly assigned to receive either a newly formulated heart
medication or the currently available heart medication and are followed to
monitor for the effectiveness of each medication is a/an:

Experimental study

Case study

Cohort study

Case-control study

Cross-sectional study

10One
advantage to using a cohort study is that results of the study can be retrieved
quickly.

True
False

11Which of
the following comparisons between the case-control study design and the cohort
study design is correct?

The case-control design is better for studying
rare exposures than the cohort design.

The case-control design is more expensive than
the cohort design.

The case-control design is better for studying
rare diseases than the cohort design.

The case-control design is better for
determining disease incidence than the cohort design

The case-control design is less prone to
recall bias than the cohort design.

12Cohort
Studies generally look at which of the following?

Determining the sensitivity and specificity of
diagnostic methods

Identifying patient characteristics or risk
factors associated with a disease or outcome

Variations among the clinical manifestations
of patients with a disease

The impact of blinding or masking a study
population

13One of
the key features of analytic epidemiology is:

Use of an appropriate comparison group

Laboratory confirmation of the diagnosis

Publication in a peer-reviewed journal

Statistical analysis using logistic regression

14Jacob is
interested in whether the mere presence of others affected individual behavior.
For his study, individuals were brought in and asked to make a speech to either
an empty room or a room with five people in it. This type of study is best
described as a/an:

Experimental study

Naturalistic observation

Case study

Cohort study

Cross-sectional

15A
researcher examines the injuries received in auto accidents in a group of males
who are intoxicated while driving compared to another group that is not. The
incidence of automobile wrecks is found for both groups at 1 and 5 years
respectively. This is an example of a/an ________ study.

Experimental

Observational

Cohort

Case-control

Cross-sectional

16Which of
the following refers to an in-depth study of one individual?

Experimental study

Naturalistic observation

Case study

Cohort study

17A teacher
would like to identify students’ attitudes about using calculators to complete
math assignments. Which of the following research methods would be most
appropriate?

Case study

Laboratory observation

Standardized test

Questionnaire

18Several
disadvantages to using cohort studies may exist. Which of the following
statements is incorrect?

It may take many years to detect changes in
the groups

Researchers may be tempted to decrease the
length of the study due to the time involved

Participants may drop out of the study as time
passes

Cohort studies may be very costly

19Which
study design involves the simultaneous comparison of individuals of different
ages?

Cross-sectional study

Longitudinal study

Sequential study

Experimental study

20Dr. Zell
is interested in studying how reflexes change throughout the lifespan. He
decides to study seven different age groups at the same point in time. Dr. Zell
is using a:

Cohort design

Cross-sectional design

Longitudinal design

Sequential design

21In
descriptive epidemiology our objective is to:

Describe the population

Describe the data we collected

Infer something about the population

Compute an average

22A(n)
_____ study is loosely structured and designed to investigate and provide
further understanding of a subject matter.

Formal

Causal

Exploratory

Experimental

Descriptive

23Which of
the following is most likely to be an experimental study?

A study of the maternal characteristics of
successful elementary school teachers

A study that compares the blood pressure readings
of drivers and passengers

A study to determine if employers give more sociable
employees higher ratings

A study to find out if implementing group projects
will increase GPAs

24One of
the strengths of a longitudinal design is that:

It eliminates generation effects completely

Data can be collected quickly and
inexpensively

You can see developmental changes in behavior
more clearly

Both b and c

All of the above

25Which of
the following is true of cross-sectional studies:

The cross sectional study is the best study
design for assessing the causes of diseases.

The cross sectional study must be done in
person.

The cross sectional study can assess for an
association between exposure and disease.

The cross sectional study is the best study
design for determining disease incidence.

The cross sectional study is the most
expensive study design.
