What is the OQ-45 assessment?

The OQ-45 (Outcome Questionnaire-45) is a 45-item self-report measure assessing patient progress across three domains: Symptom Distress, Interpersonal Relations, and Social Role. It's the most validated outcome measure in psychotherapy with 200+ peer-reviewed studies.

How does OQ clinical feedback improve outcomes?

Research shows that providing therapists with real-time OQ feedback improves outcomes by 50% and reduces treatment failure by 50%. The Expected Treatment Response algorithm identifies at-risk patients early.

What is the difference between OQ-45 and OQ-30?

The OQ-45 is the full 45-item assessment taking 5-10 minutes. The OQ-30 is a shorter 30-item version for situations where briefer administration is needed, while maintaining strong psychometric properties.

Is there a version of OQ for children and adolescents?

Yes, the Y-OQ 2.01 (Youth Outcome Questionnaire) is designed for ages 4-17, with parent-report and self-report (ages 12+) versions available.
