Dr. Chelminski's main research focus is on psychiatric comorbidity, diagnostic precision and assessment completeness. The ultimate research question that she and her colleagues are trying to tackle is whether improved diagnostic practice will result in improved treatment outcome and outcome prediction. Currently, she is involved in the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project, which is an ongoing study of involving the integration of research assessment methods into routine clinical practice. A primary focus of this project is the development and investigation of newly constructed measures of symptom severity/impairment and self-report questionnaires for patients. Projects have included validation of a questionnaire designed to assess DSM-IV major depressive disorder (Diagnostic Inventory for Depression, DID), a questionnaire that screens for major DSM-IV diagnoses (the Psychiatric Diagnostic Screening Questionnaire, PDSQ), and a multidimensional scale that assesses both general psychopathology and psychosocial functioning that can be used as an outcome measure (the Multidimensional Assessment of Symptoms and Psychosocial Functioning, MASP). At present Dr. Chelminski is also involved in the development of a scale to be administered by bariatric surgeons to determine which patients should be referred for a more complete psychiatric evaluation prior to bariatric bypass surgery.
