Diagnosis of Depression and Depressive States

Not only is there much disagreement regarding the sources of depression, but it seems quite clear that the term "depression" can refer to many different states, conditions, and specific diagnoses. Depression varies from the mild to severe, from the psychotic to the nonpsychotic, and various depressive conditions differ both qualitatively and quantitatively. Further, research has suggested different treatment approaches for differing depressive diagnoses, with certain diagnoses calling for one therapeutic response and others failing to respond to such interventions. Managed care requires treatment planning that depends upon diagnosis and outcome assessment, which is the measurement of changes in a diagnosed condition. Accurate diagnosis of depression is therefore of vital importance.
