Quick Study: Research Flashcards
Randomly assign groups to either an intervention group or control group. Considered unethical to withhold treatment to people who need it.
Randomized Controlled Trial
AKA
Experimental Study
Participants are not assigned randomly to two groups
Quasi-experimental Design
Start with a baseline measure of client’s status/condition, provide intervention, and then measure the status/condition
Single Subject Design
Participants are asked to look back and try to remember what they were like at an earlier time.
Retrospective Design
Researches collect data at a single point in time from participants of different ages. e.g. get data from people in 20s, 30s, 40s about a same thing
Cross-sectional Design
Same people are measured at different ages.
Longitudinal Design
Combination of cross-sectional and longitudinal design. Same people in different age groups are followed over time.
Cross-sequential design
Confidence that can be placed in the cause-and-effect relationship in a study “the treatment really made that result happened.”
Internal Validity
The extent to which an effect in research can be generalized to other populations/settings/treatment
External Validity
The extent to which the results of a test corresponds to other good test
“nursing students who score well on the practical test also score well on the paper test” - these tests have ? validity.
Concurrent Validity
This tells you how well a certain measure/result can predict future behavior.
“Based on Tom’s test scores, you predict his future performance as a supervisor at a later date. “
Predictive Validity
The overall consistency of a research study or measuring test.
Reliability
The degree to which a test measures what it claims to be measuring
Construct Validity
The phenomenon or reaction to be tested or measured when a new stimulus, condition, or treatment is introduced
Dependent Variable
