The Solomon four-group design is a type of experiment where participants get randomly assigned to either 1 of 4 groups that differ in whether the participants receive the treatment or not, and whether the outcome of interest is measured once or twice in each group.
The Solomon four group design is a way of avoiding some of the difficulties associated with the pretest-posttest design. This design contains two extra control groups, which serve to reduce the influence of confounding variables and allow the researcher to test whether the pretest itself has an effect on the subjects.
The Solomon four-group design is a research method developed by Richard Solomon in 1949. [1] It is sometimes used in social science, psychology and medicine. It can be used if there are concerns that the treatment might be sensitized by the pre-test. [2]
Feb 26, 2018 · For demonstrating causality, scholars may utilize a Solomon-four-group design (groups with and without pre-test measure and with and without intervention) to capture the impact of work...
In the Solomon four-group design, the researcher uses four groups. Two groups are treated as they would be in a classic experiment—pretest, experimental group intervention, and post-test. The other two groups do not receive the pretest, though one receives the intervention.
The Solomon four-group design is a research design that attempts to take into account the influence of pretesting on subsequent posttest results. Some research designs include a pretest, which is taken before exposure to a treatment, and a posttest, which is administered after exposure to a treatment.
The Solomon four group test is a standard pretest-posttest two-group design and the posttest only control design. The various combinations of tested and untested groups with treatment and control groups allows the researcher to ensure that confounding variables and extraneous factors have not influenced the results.

Solomon four group research design involves both of the above types of designs, using 2 pairs of control and experimental groups. One group receives both a pretest and a post-test, while the other receives only a post-test.
Oct 19, 2011 · In a Solomon 4-group design, participants are randomly allocated to one of four arms: (1) assessed experimental group; (2) unassessed experimental group (3) assessed control group; or (4) unassessed control group.
