The Reliability of the Mecholyl Test

ERWIN J. LOTSOF Ph.D.1 and JAMES YOBST M.D.1

1 Psychology Department, University of California, Los Angeles, Calif., and Columbus Receiving Hospital, Columbus, Ohio

Thirty patients in a psychiatric hospital and 15 medical students were administered mecholyl and epinephrine on each of 2 occasions. Systolic blood pressure readings were obtained and an attempt made to establish the reliability of the aforementioned drugs. Reaction to epinephrine as reflected in systolic pressure was "somewhat" reliable. Reactions to mecholyl, on the other hand, indicated a rather low order of test-retest reliability. It is suggested that if response to mecholyl is used as an indicator of either EST or autonomic responsivity an attempt should be made to increase the reliability. The validity of the test cannot be assessed until the reliability of the test itself is assured.
