The following output was used to evaluate the effectiveness of an intervention designed to decrease generalised anxiety disorder (GAD) symptoms.  Ratings of GAD symptoms were made on a 0-10 scale, with higher scores indicating more symptoms.  Ratings were made at the start of the study (Intake), end of the study (Discharge), and at a 1-year follow-up (Follow-up); thus the independent variable in this case is Time.
