Rehabilitation Psychologist

Psychologists hold a doctoral degree (PhD, PsyD or EdD) and are licensed by a state board. They provide talk therapy and are the only non-physician group generally licensed to administer and interpret psychological testing, such as assessments for ADHD, learning disorders or personality. In most states they cannot prescribe medication.
