A guide to psychological assessment methods
Jonathan Rich, Ph.D.
CA Psychologist PSY10259

Psychological testing techniques are a crowning achievement of scientific psychology. Best known clinical instruments include the Wechsler IQ tests, the MMPI-2, and the Rorschach test. Testing can be used to quantify almost any psychological construct, including personality, psychopathology, skills and attitudes. This website has been online for over 20 years and reflects my passion for psychology, testing, and psychological assessment.
