1. Read textbook chapters 1, 3, 4 and 6 . After reading the assigned chapters and reviewing the posted content for this week, think about the importance of research and evidence based practice to the profession of nursing. Think of your own clinical prac

There are two main types of research – quantitative and qualitative ◦ Quantitative – uses numbers, data to answer a
question
◦ Qualitative- uses thoughts and experiences to explore a topic
We’ll discuss each in more detail in a few weeks but for now we’ll review the overall steps involved in each
Number of steps can differ but: ◦ Research always proceeds in an orderly fashion
◦ Research always starts with the identification of the problem and ends with the utilization of the findings
Identify the problem/determine purpose of study
Review of the literature/develop framework Formulate hypothesis/research question Define study variables/terms Select research design Identify the population Select the sample Collect data Analyze the results Interpret and communicate the findings
???????
Start with broad topic area Narrow to specific problem statement Get study problem from ◦ Personal experiences ◦ Literature sources ◦ Prior research ◦ Theory testing
State problem as a question Include population and variables Determine the Purpose ◦ Difference between purpose and problem ◦ Problem tells what is studied ◦ Purpose tells why study is done
Studies may have one or both
Finds out what exists on the topic Helps look at theory/framework Helps address the study methods Search a variety of sources ◦ Indexes ◦ Abstracts ◦ Dissertations ◦ Computer searches
Continue until time to collect data Develop a Theoretical/Conceptual Framework ◦ Research helps test, develop, refine theories ◦ Process assists in selection of study variables ◦ Directs the hypothesis and interprets findings ◦ Answers the “so what” question(s) ◦ Adds to our nursing body of knowledge
Hypothesis predicts relationships between
variables Hypothesis provides predicted answer to
question Hypothesis contains two types of variables ◦ Independent variable ◦ Dependent variable
Hypothesis is testable empirically Types of hypothesis vary Hypothesis mostly in quantitative studies ◦ Directional ◦ Non-directional ◦ The Null hypothesis
They must be clear to the researcher and reader
The definitions may be ◦ Dictionary
◦ Theoretical
◦ Operational
The operational definition helps with study replication
Helps determine how study is planned
Varies with the type of study conducted ◦ Quantitative vs. Qualitative
◦ Experimental vs. Non-experimental
◦ Experimental may be divided
True experimental
Quasi-experimental
Pre-experimental
Population ◦ Target ◦ Accessible
Generalization Select the Sample A subgroup of the population It represents the population It helps with generalization Types of samples ◦ Probability Samples ◦ Non-probability Samples

Data
Pieces of information or facts
Data collection procedures are followed
Questions asked are ◦ What data? ◦ How is it collected? ◦ Who collects the data? ◦ Where is it collected? ◦ When will it be collected?
Organize the Data for Analysis
This step is planned from the beginning
It uses the help of a statistician
Decisions are made about missing data
The process is easier now
Data is placed into computerized statistical packages
Results are analyzed instantaneously
Interpret the Findings Do the data support the research hypothesis? Do the data not support the research hypothesis? Problems encountered are discussed Limitations of the study are presented Results are compared with other studies Implications are identified Recommendations are proposed Communicate the Findings A very critical component of the process A variety of ways are used
◦ Journals ◦ Presentations ◦ Posters
Utilize the Findings Recommendations need considerations Integration into practice are critical components Researcher may act as a consultant for using findings Researcher must disseminate findings in many ways
Inductive or open to new ideas and theories
Concerned with in-depth descriptions of people or events
4 common approaches ◦ Phenomenology
◦ Grounded theory
◦ Ethnography
◦ Historical
Identify the phenomenon to study
Select the research design
Review the literature
Select the sample
Collect the data
Analyze the data
Communicate the study results
General to more focused
Broad statements
Purpose statement
Depends on the phenomenon being studied
Debate on when to do this
May bias the study results
Preferred at the end of the study
Tells how results fit with the body of knowledge
Smaller in size
No set rules
Saturation is more important
Also need to gain entry to the research site ◦ IRB approval
◦ Key informants
Begins when the data is collected
Content analysis procedures (software programs)
