The interrupted time series design involves:
A) making an observation immediately before and immediately after a treatment is instituted.
B) using time as the independent variable.
C) making observations over an extended period of time before and after a treatment is instituted.
D) comparing treatment and control groups over an extended period of time.
Interrupted Time Series Design
A quasi-experimental design where observations are made over time both before and after an intervention to detect whether the intervention has an effect distinct from underlying trends.
Observation
involves systematically capturing or recording behavior, phenomena, or events as they naturally occur, without manipulation by the observer.
Treatment
In research, an intervention or condition that is applied to a group of subjects to observe its effects, often compared to a control group without the intervention.
- Determine the appropriate circumstances and methods for utilizing interrupted time series design and its various forms in research studies.

Final Answer :
C
Explanation :
The interrupted time series design involves making observations over an extended period of time before and after a treatment is instituted. This allows researchers to examine any changes in the outcome variable that may be associated with the intervention. Time is used as a variable in this design, but it is not the independent variable. Treatment and control groups may or may not be used in this design, so option D is not accurate. Option A describes a pre-post test design and is not specific to interrupted time series.
