The Solomon four-group design is a research method that allows for the examination of both the effects of an intervention and the potential impact of pre-testing on those effects. It does this by using four groups: two that receive a pre-test (one of which gets the intervention and one that does not) and two that do not receive a pre-test (again, one receives the intervention and one does not). This design explicitly controls for interactive testing effects (such as how taking a pre-test might influence the results), and because it involves multiple groups and testing phases, it is indeed more expensive and time-consuming to implement than simpler experimental designs. Additionally, it can be used to examine changes in attitudes among individual respondents, making all the provided statements true.
