A 2-year supermarket intervention in 20 pair-matched stores tested whether a nutrition education program could produce changes in food purchasing behavior. Food sales data for 2
intervention years were compared with baseline year data. The evaluation presented challenges
related to the quasi-experimental study design and to the high variability and auto- and
cross-sectional correlations in the data. A complex time series model was used to take these
factors into account and to test for intervention effects.
