Patients' and clinicians' perspectives on relevant treatment outcomes in depression: qualitative study.

Classically defined study outcomes based on symptom resolution only partly reflect issues considered important by patients and clinicians in specialist depression treatment. Incorporating patients' and clinicians' perspectives in the development of measurable end-points makes them more suitable for use in trials and subsequent translation to clinical practice. Furthermore, evaluating patients' perspectives on treatment outcomes helps in the development of tailored interventions according to patients' needs.
