  "field": "Environment",
  "definition": "The interrupted time series design involves repeated measurement of an indicator (e.g., reported crime) over time, encompassing periods both prior to and after implementation of a program. The goal of such an analysis is to assess whether the treatment (or program) has \"interrupted\" or changed a pattern established prior to the program's implementation. However, the impact of alternate historical events may threaten the interpretation of the findings.",
