The randomized controlled trial (RCT), which is an experimental design, is considered the strongest design to provide healthcare professionals with information regarding the benefits of a specific healthcare. Like the RCT, the pretest-posttest design also is experimental in nature; however, a fundamental weakness of the pretest-posttest design centers on challenges with attributing causation when there is neither randomization nor a control group. The Solomon four-group design is a variation of the pretest-posttest design. Case control studies, which represent a nonexperimental study design, are challenged by difficulty in establishing that exposure to the causative factors actually occurred
before the outcome.
