In a nonequivalent control group interrupted time series design, the independent variable is both a repeated measures variable (as it is measured repeatedly over time) and an independent-groups variable (as it is manipulated between groups). It is not a dependent variable, and while this design attempts to increase internal validity, it does not guarantee it. The frequency of studying the independent variable is determined by the timing and frequency of data collection in the study.
