In order to find the best information on a topic, not only
should you develop a question and search for resources, but you should also
know how to analyze the value of the resources that you identify. There are
different ways to evaluate resources, such as using the hierarchy of evidence,
which you explored in Week 4 of this course. Another way to evaluate resources
is to consider the appropriateness of the research design. Understanding how
research designs contribute to the quality of a study is essential for being
able to analyze resources when conducting a literature review or locating
evidence for practice.

In this Discussion, you consider the different research
designs and evaluate how these designs have been used to research a specific
topic. You also consider strategies for selecting an appropriate research design.

To prepare:

Review the information in the course texton quantitative
research designs. Focus on the information in Box 9.1, “Guidelines for
Critiquing Research Designs in Quantitative Studies” located on page 230 of the
course text.

Select a topic from the list below and search the Walden
Library to find two different quantitative research studies addressing that

Caregiver stress

Anxiety in children

Sleep apnea

Depression in college freshmen

Rural health care issues

Post-traumatic stress syndrome

Traumatic brain injury in veterans

Health effects of environmental contaminants

Bipolar disorder

End-of-life ethical issues

Alternative medicine

For each of the sources that you select, identify the type
of quantitative research design used, and evaluate whether it is the most
appropriate approach to the research.

Consider the ramifications of choosing an inappropriate
design for a research study.

By Day 3

Post the topic you selected, references for the two sources
you identified, and the quantitative research design used in each. Critique the
appropriateness of the design used and justify your comments with information
from the Learning Resources. Discuss the ramifications of choosing an
inappropriate design for a research study.

Read a selection of your colleagues’ responses.

By Day 6

Respond to at least two of your colleagues on two different
days in one or more of the following ways:

Ask a probing question, substantiated with additional
background information, and evidence.

Share an insight from having read your colleagues’ postings,
synthesizing the information to provide new perspectives.

Offer and support an alternative perspective using readings
from the classroom or from your own review of the literature in the Walden

Make a suggestion based on additional evidence drawn from
readings or after synthesizing multiple postings.
