Clinical assessment of psychopathology and personality with emphasis on the MMPI-2-RF (Restructured Form), MMPI-2 and MMPI-A. My program of research focuses on developing the conceptual and empirical foundations for use of the MMPI instruments in a variety of applied assessment settings (e.g., outpatient, inpatient, personnel screening, forensic, correctional, adolescent residential, and substance abuse treatment).
