Results:
1. The mean OQ-45 improvement per week is statistically significant and equal to 3.28/week. (n=126, p <.001).
2. There is no statistically significant difference in treatment efficacy based on demographic differences. Demographics include sex, age, marital status.
3. There are no statistically significant differences between the average efficacy of any individual therapist or any individual psychiatrist (appendix ).
4. A patient’s previous level of care does have a major impact on their rate of improvement, BUT the incoming risk assessment does not. Patients who were previously in inpatient care show a much faster rate of improvement than any other category. The second fastest was no previous care, and the other categories were slower at a rate that was similar to one.
5. The intake assessments of risk had no bearing on the treatment efficacy. All three categories were statistically identical.
6. The intake diagnosis does have a notable impact in one regard: bulimia. Patients diagnosed with bulimia have a notably slower (and statistically significant) difference in their rate of improvement. This effect holds up when controlling for other Other diagnoses do not result in a statistically significant difference.
7. There is no relationship between patient satisfaction and OQ45 score improvement.
