Interrupted time series (ITS) is arguably the strongest quasi-experimental research design3–5—particularly when Webbsufficiently long time series, the median time point of the preintervention period is a good choice of a pseudo-start period to maximize power to detect a significant jump (because the subsample will be evenly split on both sides). For shorter time series, a simple iterative process of testing each preintervention time period as the pseudo-

The time series refers to the data over the period, while the interruption is the intervention, which is a controlled external influence or set of influences. Effects of the intervention are evaluated by changes in the level and slope of the tim…
