He is author of the revised Interview Guide to Diagnose DSM-V Psychiatric Disorders and the Mental Status Examination.

In the 1980s, Dr. Zimmerman developed a self-report questionnaire to diagnose DSM-III major depressive disorder, and was one of the authors of the first semi-structured interview to assess the Diagnostic and Statistical Manual of Mental Disorders, 3rd edition (DSM-III) personality disorders. More recently he has developed the Psychiatric Diagnostic Screening Questionnaire, Diagnostic Inventory for Depression, Remission from Depression Questionnaire, and the Clinically Useful Depression Outcome Scale (CUDOS) and Clinically Useful Anxiety Outcome Scale (CUXOS). The CUDOS and CUXOS are included in the first web-based outcome evaluation system (www.outcometracker.org).
