Re: Topic 7 DQ 1

Evidence-based research is considered an integration of clinical expertise, patient value, and research
that is conducted to establish the best practice to use for better patient care (EBP Overview, 2018).
According to the evidence-based practice overview, there are several steps that can be taken when
conducting evidence-based research.
The first step is to determine an area that needs improvement. Then the researcher will develop a well-
built clinical question called the PICOT question. The PICOT question involves the population,
intervention, comparison, outcome, and timeframe of achieving the proposed outcome (EBP Overview,
2018). The goal of the PICOT question is to determine what the researcher is trying to accomplish with
the patient.
The second step is selecting the appropriate resources to conduct the research. According to DeNisco
and Barker (2016) there are several resources that a researcher can use that are reliable such as the
Cochrane Library, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline,
PubMed, and the Joanna Briggs Institute Library.
The next steps of evidence-based research are checking the validity to the research, evaluate the
finding, and then implementing the research into current practice (EBP Overview, 2018).

Re: Topic 7 DQ 1
Janisse,
Thank you for the great post. I agree with you that checking the validity of the research is very
important. “Determining how rigorously the issues of reliability and validity have been addressed in a
study is an essential component in the critique of research” (Heale & Twycross, 2015, p. 66). There are
three key measures used to determine validity of research content, construct and criterion (Heale &
Twycross, 2015). Content measures if the research instrument used covers all the content of the
variable (Heale & Twycross, 2015). Construct refers to the ability for one to “draw inferences about test
scores related to the concept being studied” (Heale & Twycross, 2015, p. 66). Criterion is based on
correlations of using different methods to measure the same variable. One must decide if the
measurements used in the study make it valid in order to support implementing the study findings into
a practice change.
