Week 6 discussion
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.

Our goal is to help as many students as possible with their assignments, i.e. our prices are affordable and services premium.

  • Discussion Questions (DQ)

Initial responses to the DQ should address all components of the questions asked, including a minimum of one scholarly source, and be at least 250 words. Successful responses are substantive (i.e., add something new to the discussion, engage others in the discussion, well-developed idea) and include at least one scholarly source. One or two-sentence responses, simple statements of agreement or “good post,” and responses that are off-topic will not count as substantive. Substantive responses should be at least 150 words. I encourage you to incorporate the readings from the week (as applicable) into your responses.

  • Weekly Participation

Your initial responses to the mandatory DQ do not count toward participation and are graded separately. In addition to the DQ responses, you must post at least one reply to peers (or me) on three separate days, for a total of three replies. Participation posts do not require a scholarly source/citation (unless you cite someone else’s work). Part of your weekly participation includes viewing the weekly announcement and attesting to watching it in the comments. These announcements are made to ensure you understand everything that is due during the week.

  • APA Format and Writing Quality

Familiarize yourself with the APA format and practice using it correctly. It is used for most writing assignments for your degree. Visit the Writing Center in the Student Success Center, under the Resources tab in Loud-cloud for APA paper templates, citation examples, tips, etc. Points will be deducted for poor use of APA format or absence of APA format (if required). Cite all sources of information! When in doubt, cite the source. Paraphrasing also requires a citation. I highly recommend using the APA Publication Manual, 6th edition.

  • Use of Direct Quotes

I discourage over-utilization of direct quotes in DQs and assignments at the Master’s level and deduct points accordingly. As Masters’ level students, it is important that you be able to critically analyze and interpret information from journal articles and other resources. Simply restating someone else’s words does not demonstrate an understanding of the content or critical analysis of the content. It is best to paraphrase content and cite your source.

  • LopesWrite Policy

For assignments that need to be submitted to Lopes Write, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me. Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes. Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own? Visit the Writing Center in the Student Success Center, under the Resources tab in Loud-cloud for tips on improving your paper and SI score.

  • Late Policy

The university’s policy on late assignments is a 10% penalty PER DAY LATE. This also applies to late DQ replies. Please communicate with me if you anticipate having to submit an assignment late. I am happy to be flexible, with advance notice. We may be able to work out an extension based on extenuating circumstances. If you do not communicate with me before submitting an assignment late, the GCU late policy will be in effect. I do not accept assignments that are two or more weeks late unless we have worked out an extension. As per policy, no assignments are accepted after the last day of class. Any assignment submitted after midnight on the last day of class will not be accepted for grading.

  • Communication

Communication is so very important. There are multiple ways to communicate with me: Questions to Instructor Forum: This is a great place to ask course content or assignment questions. If you have a question, there is a good chance one of your peers does as well. This is a public forum for the class. Individual Forum: This is a private forum to ask me questions or send me messages. This will be checked at least once every 24 hours.
