Question

Quizplus · Accepted Answer

An interrupted time series design involves measuring the outcome variable multiple times over a period of time, and then introducing an intervention (in this case, increasing the drinking age) at a specific point in time to see if there is a change in the outcome variable. This design is appropriate for this study because it allows for comparison of alcohol-related traffic accidents before and after the intervention. A longitudinal design would follow a group of individuals over a long period of time, which is not necessary for this particular study. A control series design would involve comparing the outcome variable in a control group that did not receive the intervention, which is not applicable in this case. An ABAB design would involve introducing and withdrawing the intervention multiple times, which is not necessary for this study.
