In this video, Dr. Kristen Mauk explains specific quantitative research designs, methods, and considerations related to her Doctorate of Nursing Practice (DNP) project. She discusses how she developed her research design and how she used sound quantitative research methods throughout her project.

2.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. Identify at least one potential concern that could be raised about the study’s internal validity.

· 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.
