Validity in Quantitative Research Designs
Paper , Order, or Assignment Requirements
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:
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). The 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.
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.

We have spoken at great lengths about the importance of leadership to the success of any quality improvement efforts. Organizations such as ThedaCare, Mayo Clinic, or Virginia Mason are heralded as role models in their use of Process improvement methodologies and the support and organizational structure that has promoted the successful implementation of QI initiatives. Using market analysis reports, publish research and organizational analysis data:
– Identify what makes some healthcare organizations better in terms of quality of care than
others
Make sure to use a big enough sample for your analysis (at least 10 healthcare companies should be
mentioned by name include virginia mason, thedacare and Mayo clinic) and ; I encourage you to use secondary research as well, from outlets such at Harvard
Business Review, McKinsey, PwC and other applicable journals).
please briefly include 10 healthcare organizations and what makes them stand out in terms of quality and process improvement from other hospitals etc. Can be 1-1.5 pages long, size 10 font .
