Clinical psychologists receive extensive training in psychological test administration, scoring, interpretation, and reporting, while psychiatrists are not trained in psychological testing. In addition, psychologists (particularly those from Ph.D. programs) spend several years in graduate school being trained to conduct behavioral research; their training includes research design and advanced statistical analysis. While this training is available for physicians via dual MD/Ph.D. programs, it is not typically included in standard medical education, although psychiatrists may develop research skills during their residency or a psychiatry fellowship (post-residency). Psychologists from Psy.D. programs tend to have more training and experience in clinical practice (e.g. psychotherapy, testing) than those from Ph.D. programs.
