The Doctor of Psychology (Psy.D., D.Psych, or Dr.Psych.; New Latin Psychologiae Doctor or Doctor Psychologiae) is a professional doctoral degree intended to prepare graduates for practice in psychology. Earning the degree was originally completed through one of two established training models for clinical psychology. However, Psy.D. programs are no longer limited to Clinical Psychology as several universities and professional schools have begun to award professional doctorates in Business Psychology, Organizational Development, Forensic Psychology, Counseling Psychology, and School Psychology.
The degree is usually abbreviated as Psy.D. in the United States and Canada and also D.Psy. or D.Ps. in Canada. In the United Kingdom and Ireland, it is often abbreviated as D.Clin.Psych, Clin.Psy.D., or Psych.D. In Australia, it is often abbreviated as D.Psych.
The initial guidelines for the education and training of clinical psychologists were established in 1949 at an American Psychological Association (APA)-sponsored Conference on Training in Clinical Psychology in Boulder, Colorado. Students would be prepared both to conduct experimental research and apply knowledge for clinical practice. This approach became known as the scientist-practitioner model, although it is often referred to as the Boulder model since the conference was held in Boulder, Colorado.
The difficulty integrating the education and training for both research and practice within the same degree has been long recognized. While the scientist-practitioner model ostensibly included clinical training, many argued that preparation for practice was often neglected. Some also argued that in trying to train students in both research and practice, not enough emphasis was placed on either. In regard to research, the modal number of publications by graduates of Ph.D. programs was zero. In regard to practice, students were not being trained effectively for the needs of people seeking services.
