Nursing Research 3
Qualitative Research - Ethnography
"a portrait of people" Roots: Anthropology (culture/groups of people), Assumes that people evolve a culture that gives direction to their lives / Very much associated with fieldwork Question: What is this? What is happening in this subculture?
Odds Ratio
"the probability" indicates how much more likely certain independent variables (factors) predict the probability of developing the dependent variable (outcome).
Null Value
"the value of no effect" which varies according to the outcome measure.
Measures of dispersion (variability)
(Measure of Spread) Measures the degree to which data points (Scores) are spread out to each other
outcome variable
(outcomes research-a type of research that evaluates the impact of health care on the health outcomes of patients and population, including evaluation of economic impacts linked to health outcomes, such as cost effectiveness and cost utility.
Pre-experimental study
- manipulation of independent variable - NO control group & NO randomization + limited control over extraneous variables
Significant results
- probability that an effect occurred by chance less than 5 times out of 100 (p<.05) is statistically significant and we reject the null hypothesis and thereby support the alternative hypothesi
What is the range that correlation coefficients can range from
-1.00 to +1.00
Internal validity
-Asks whether the IV really made the difference or the change in the dependent variable. -Established by ruling out other factors or threats as rival explanations. -Must be established before external validity can be established.
Constancy
-Data collection procedures are the same for each subject; data collected in the same manner and under the same conditions.
Randomization
-Each subject in a population as an equal chance of being selected. -Each subject in the study has an equal chance of being assigned to the control group or the experimental group.
Manipulation of the Independent variable
-Experimental and control groups -The independent variable is: the variable that the researcher hypothesizes will have an effect on the dependent variable. Usually manipulated (experimental study) but sometimes cannot be manipulated (nonexperimental)
When considering a practice change, why is identification of stakeholders important?
-Facilitates implementation of the proposed change -Decreases misunderstandings related to the change -Allows for clarification of the purpose of the proposed change
Means of control:
-Homogenous sample -Consistent data-collection procedures -Manipulation of IV -Randomization
Cronbach's alpha (Likert-type response)
-Most commonly used test of internal consistency; a Likert scale format asks the subject to respond to a question on a scale of varying degrees of intensity between two extremes.
The historical background that led to the development of ethical guidelines for the use of human subjects in research
-Nazi experiments 1930's-1940's -Tuskegee: Untreated syphilis in black males: 1932-1973 -Jewish chronic disease study 1965 -San Antonio Contraceptive study 1969-impoverished hispanic women -Willowbrook: Hepatitis/gamma globulin in children: 1972 -UCLA Schizophrenia medication study: 1983 -AIDS/AZT study 1980's
Qualitative data analysis involves what process?
-Organizing data -Managing data -Prioritizing data
Homogenous sample
-Participants in the study are homogenous or have similar extraneous variables that might affect the dependent variable. Homogeneity of the sample limits generalizability or the potential to apply the results of a study to other populations.
Define external validity
-Questions the conditions under which the findings be generalized. -Deals with the ability to generalize the findings outside the study to other populations and environments.
What are the major tests of reliability?
-The reliability coefficient expresses the relationship between the error variance, true variance, and the observed score. -Scored between 0-1. -0 means no relationship -1 means 100% reliability. -Closer to 1 more reliable. -An instrument should be 0.70 or higher to be considered reliable.
In contrast to quantitative studies, the literature reviews of qualitative studies are usually handled in a different manner. How is this so?
-There is often little known about the topic under study. The literature may be conducted at the beginning of the study or after that data analysis is completed with qualitative.
In deciding how to apply evidence to practice, nurses must incorporate additional sources of information in making patient care decisions. These are
-any policy or cost considerations. -the individual patient experience. -the clinical experience.
Sources of data in qualitative research include
-direct observations. -artifacts such as documents, photographs, and physical objects. -in-depth interviews
Accepted strategies for generating meaning from qualitative data include
-noting patterns or themes and building a logical chain of evidence. -making contrasts or comparisons and noting relationships between variables. -clustering, counting, and making metaphors.
Nurses can utilize resources designed to rank and evaluate evidence provided by
-the Cochrane Collaboration. -the U.S. Preventive Services Task Force. -the Joanna Briggs Institute.
While qualitative researchers must adhere to the same ethical standards as quantitative researchers, unique ethical considerations apply to
-the relationship between the researcher and participant -data-management procedures
