2. The decision is also influenced by the depth of clinical knowledge of the team.
Which type of study is it?
Experimental - Must have 2 groups -1 group that has the intervention and 1 group that has NO intervention and the participants must be randomly chosen. Experimental studies must have all three -
Meta-analysis - quantitatively synthesizes & analyzes findings of multiple primary studies addressing a similar question (Newhouse, et al., 2007, p. 79)
Quasi-experimental - "performed when it is not practical, ethical, or possible to randomly assign subjects to experimental or control groups." (Newhouse, et al., 2007, p. 79)
Non-experimental - studies what has already happened. "lt involves the study of naturally occurring phenomena (groups, treatments, and individuals) without the introduction of an intervention. (Newhouse, et al., 2007, p. 79)
Qualitative - "represent a category of descriptive research (historical, grounded theory, ethnographic) that challenges the traditional scientific worldview." (Newhouse, et al., 2007, p. 85)
Meta-Synthesis - synthesizes & analyzes qualitative scientific evidence
