The Clinical Psychological Sciences major within the Department of Psychological Sciences dates to the very beginning of the subdiscipline of clinical psychology. In 1935, the American Psychological Association (APA) recommended that clinical psychologists receive specialty training. In 1948, the Clinical Psychology Program at Purdue University was accredited by the APA and has been continuously accredited since that time. The purpose of the Doctoral Program in Clinical Psychological Sciences is to train students who are involved in the generation of new knowledge in psychology, and competent in the professional application of clinical science to the prevention and remediation of clinical problems. A general background in general and clinical psychology is provided by didactic courses and seminars. Research expertise is honed through apprenticeship to an active clinical science researcher and the completion of a first-year project, M.S. thesis, Preliminary Exam, and Ph.D. dissertation. Clinical experience is provided by participation in both in-house and external practica (see Purdue Psychology Treatment and Research Clinics (PPTRC) pages). The breadth and integration of academic work, research, and clinical training are consistent with standards set forth by the American Psychological Association (APA).
