The Soloman Four Group Design is a research method that 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.[1] The four groups have four different experiences:
- Pre-test, treatment, post-test
- Pre-test, no treatment, post-test
- Treatment, post-test
- No treatment, post-test
The effectiveness of the treatment can be evaluated by comparisons between groups 1 and 2 and between groups 3 and 4.
