3 Discussion 1
Given that there is a
documented advantage to the use of an experimental and control group design,
discuss why other designs are frequently used, and the situations that may
prompt the use of one.

3 Discussion 2
Discuss your understanding
of the concept of internal validity in a research study, and the impacts of
several errors or biases that can reduce the study’s validity.

3 Assignment 1
Coyne and Messina
Articles, Part 1 Analysis
Details:
1) In a paper (1,000-1,250
words), compare and contrast the major elements of the reports by Coyne et al.
and Messina et al., listed in the Module 2 Readings.
2) Complete the “Coyne and
Messina Articles Analysis.” Study the information in the right-side column
related to the Coyne, et al. study, which identifies the required elements as
found in the reading. Complete the information for the Messina et al. article
by identifying the required elements from the article.
3) Prepare this assignment
according to the APA guidelines found in the APA Style Guide, located in the
Student Success Center. An abstract is not required.
4) This assignment uses a
grading rubric. Instructors will be using the rubric to grade the assignment;
therefore, students should review the rubric prior to beginning the assignment
to become familiar with the assignment criteria and expectations for successful
completion of the assignment.
Coyne and Messina Articles
Analysis
As an example guideline,
review the study components in the left-side column of the table below. Read
the study by Messina et al., and build the data in the right-side column with
the key components in that study.
Research Question:
Coyne: Do size and
ownership type make a difference in the efficiency and cost results of
hospitals in Washington state? (Highlight p.164, second column, starting 15
lines from bottom to seven lines from bottom.)
Messina:
How did the research
question emerge from the review of literature in the article?
Coyne:
Built on an earlier study
by Coyne on performance differences between multi-facility systems and
independent hospitals using two cost measures. Cited studies that used a range
of variables to measure differences in hospital performance, and noted that
prior findings have been inconclusive in regard to hospital size, although
economies of scale were found.
Messina:
Independent Variables
Type:
Coyne:
Hospital size and hospital
ownership structure.
Categorical
Messina:
Dependent Variables
Type:
Coyne:
Efficiency measures –
continuous variables.
Cost measures – continuous
variables.
Messina:
Design Elements
- Quantitative
vs. Qualitative
- Sample Size
- Method of
sample selection
- Experimental
vs. control group?
- Reliable and
valid data instruments?
Coyne:
Quantitative 96
Picked all hospitals in
state, except investor owned hospitals.
No
Used data that are
commonly used to measure hospital efficiency and performance with high degrees
of accuracy (reliable), and data that are historically used and make sense to
other hospital users (valid).
Messina:
Describe analysis.
What statistics were used?
Coyne:
Two-way Analysis of
Variance (ANOVA)
Messina:
Did the researchers’
conclusions make sense, did they answer the research question, and did they
appear to flow from the review of the literature?
Did they explore control
of extraneous variables?
Coyne:
They concluded that size
and ownership type make a difference in reported levels of efficiency. Not for
profits seem to achieve higher performance levels, and medium and large not for
profits operate more efficiently than industry average. The same results were
found for cost levels, in that size and ownership type do make a difference,
with medium sized hospitals reporting lower costs than large or small
hospitals.
Yes, when they called for
national studies that controlled for case mix, scope of services, and payer
mix, all of which could have affected the results in this study in an
unmeasured way.

3 Assignment 2
Assessing a Research Study
Details:
1) Choose a research study
article of interest to you.
2) Refer to the study you
choose and complete “Assessing a Research Study.”
3) Identify an article
that directly references your chosen study and compare it to your findings.
Does this article refute or confirm the study’s findings?
4) Write a paper
(750-1,000 words) that analyzes and summarizes your findings.
5) Prepare this assignment
according to the APA guidelines found in the APA Style Guide, located in the
Student Success Center. An abstract is not required.
6) This assignment uses a
grading rubric. Instructors will be using the rubric to grade the assignment;
therefore, students should review the rubric prior to beginning the assignment
to become familiar with the assignment criteria and expectations for successful
completion of the assignment.
