Discussion: Quantitative Research Designs part 2
. 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
• 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.

• 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.

• Chapter 10, “Rigor and Validity in Quantitative Research”
This chapter introduces the concept of validity in research and describes the different types of validity that must be addressed. Key threats to validity are also explored.
• Chapter 11, “Specific Types of Quantitative Research”
This chapter focuses on the specific types of quantitative research that can be selected. The focus is on the purpose of the research rather than the research design. These include such approaches as clinical trials, evaluation research, health services and outcomes research, needs assessments, or replication studies.
