Repeated measures, or collecting multiple data points over time, helps to establish a pattern of behavior and rule out potential confounding variables. This improves the internal validity of the single-case experimental design. Process measures can also be helpful in ensuring that the intervention is being implemented as intended and in monitoring any potential changes in the participant's behavior over time. Random assignment and placebo controls are not typically used in single-case experimental designs because they are focused on the individual's response to the intervention rather than group differences.
