What is different about psyd vs phd training for psych?

Clinical focus. Although both psyd and phd psychologists are trained in the care of those with mental disorders, psyd programs focus primarily of preparing the person to be a therapist and tester, whereas phd programs also teach research techniques and require a formal, completed research project for completion of training.
Research vs Clinical. A PhD is typically a research degree that emphasizes experimentation, time in the library, and publications with lesser of an emphasis on clinical work. A PsyD on the other hand, is a clinical degree that emphasizes work with patients instead of research quite so much.
