Validity in Quantitative Research Designs
Validity in research refers to the extent researchers can be confident that the cause and effect they identify
in their research are in fact causal relationships. If there is low validity in
a study, it usually means that the research design is flawed and the results
will be of little or no value. Four different aspects of validity should be
considered when reviewing a research design: statistical conclusion validity,
internal validity, construct validity, and external validity. In this
Discussion, you consider the importance of each of these aspects in judging the
validity of quantitative research.
To prepare:
Review the information in Chapter 10 of the course text on rigor and validity.
Read the method section of one of
the following quasi-experimental studies (also located in this week’s Learning
Resources). Identify at least one potential concern that could be raised about
the study’s internal validity.
Metheny, N. A., Davis-Jackson,
J., & Stewart, B. J. (2010). Effectiveness of an aspiration risk-reduction
protocol. Nursing Research, 59(1), 18–25.
Padula, C. A., Hughes, C., &
Baumhover, L. (2009). Impact of a nurse-driven mobility protocol on functional
decline in hospitalized older adults. Journal of Nursing Care Quality, 24(4),
325–331.
Yuan, S., Chou, M., Hwu, L.,
Chang, Y., Hsu, W., & Kuo, H. (2009). An intervention program to promote
health-related physical fitness in nurses. Journal of Clinical Nursing, 18(10),
1,404–1,411.
Consider strategies that could be
used to strengthen the study’s internal validity and how this would impact the
three other types of validity.
Think about the consequences of
an advanced practice nurse neglecting to consider the validity of a research
study when reviewing the research for potential use in developing an
evidence-based practice.
By Day 3
Post the title of the study that
you selected and your analysis of the potential concerns that could be raised
about the study’s internal validity. Propose recommendations to strengthen the
internal validity and assess the effect your changes could have with regard to
the other three types of validity. Discuss the dangers of failing to consider
the validity of a research study.
Read a selection of your
colleagues’ responses.
By Day 6
Respond to at least two of your
colleagues 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 Library.
Validate an idea with your own
experience and additional sources.
Make a suggestion based on
additional evidence drawn from readings or after synthesizing multiple
postings.
Expand on your colleagues postings by providing additional insights or contrasting perspectives based on
readings and evidence.
