Chap 10-11 Flashcards
(30 cards)
Which method of data collection is most appropriate for a nurse researcher to use In a survey study?
questionnaires
Why would a nurse researcher choose to use research studies that examine the associations or relationships between variables
There is application in clinical settings and a foundation for future Experimental studies
Why would a nurse researcher choose not to use a survey study design
Information collected is relatively superficial
A nurse researcher would choose to use a correlational study of multiple variables for which purpose?
To examine relationships between or among variables
Why would a nurse researcher choose to use correlational design for a non-experimental study
It represents an efficient and effective method of collecting large amount of data about a problem
A nurse researcher will choose to use a developmental study design to do what
Allow exploration of the changing nature of relationships between variables overtime
Which statement about cross-sectional studies is most accurate?
More than one group can be compared
A nurse researcher would decide to use longitudinal or prospective design for which reason
It is associated with data that are focused and deep
A nurse researcher would decide to use retrospective or Ex post facto study for which reason
The dependent variable has already been affected by the independent variable
A nurse researcher will choose an ex post facto design over more a correlational designed for which reason
There is a greater degree of control in the design
Which type of study should be used when data are collected at only one point in time
Cross sectional
Data collection instruments were sent to the same sample of women at six different times during the first year of living with breast cancer. What type of study design does this exemplified?
Longitudinal
What threat to internal validity is most closely associated with a longitudinal design
Mortality effects
What design allows study participants to serve their own controls, allowing early Trends in the data to emerge?
Longitudinal
The longitudinal study and the prospective study are similar for which reason?
Each moves forward in time
Which type of research will assist a nurse researcher in focusing on theory and development of measurement instruments
Psychometrics
How does an experimental research design differ from nonexperimental research design?
Non-experimental designs attempt to test differences among variables, and experimental designs attempt to establish cause-and-effect relationships
Advantages to use of correlational design for a study include what? Select all that apply
Efficiency and effectiveness in Data collection

A reporting on the tools tested reliability and validity
What can a nurse researcher address in a study using a survey design? Select all that apply
