A survey of clinical psychologists determined that both objective and projective tests were used with high frequency. The two tests clinicians most frequently recommended clinical students learn to administer were projective (the Rorschach and the TAT) and, among the 10 most frequently recommended tests, projective tests were recommended approximately 30% more often than objective tests. Clinicians who were frequent test users recommended both objective and projective tests more often than those not using tests. Clinicians doing substantial teaching and research tended to recommend projective tests less often than clinicians not engaged in those activities. Behavior therapists recommended projective tests less often than eclectic, Freudian, and neo-Freudian therapists.
