Does this evidence address my EBP question?
?Yes
?No Do not proceed with appraisal of this evidence
Level of Evidence (Study Design) A. Is this a report of a single research study? If No, go to B.
1. Was there manipulation of an independent variable? 2. Was there a control group? 3. Were study participants randomly assigned to the intervention and control
groups? If Yes to all three, this is a Randomized Controlled Trial (RCT) or Experimental Study If Yes to #1 and #2 and No to #3, OR Yes to #1 and No to #2 and #3, this is Quasi
Experimental (some degree of investigator control, some manipulation of an independent variable, lacks random assignment to groups, may have a control group)
If No to #1, #2, and #3, this is Non-Experimental (no manipulation of independent
variable, can be descriptive, comparative, or correlational, often uses secondary data) or Qualitative (exploratory in nature such as interviews or focus groups, a starting point for studies for which little research currently exists, has small sample sizes, may use results to design empirical studies)
