In addition, each Chief was asked to have four of his supervisors rate each subject on a job performance evaluation form. The form contained items related to job pedormance, ability as a controller, judgment, and personality characteristics. From these two sources of information, six criterion measures were develop~d. These were: ( 1) Average . Supervisor Rating; (2) Active vs. Inactive Controller; ( 3) With the F:AA vs. Not With the FAA; ( 4) Mean Hours of Sick Leave; ( 5) No ·Symptoms vs. Symptoms; and (6) No Disciplinary Action vs. Disciplinary Action. More complete descriptions of the criterion variables are given in Table 2, together with their means and standard deviations for the maximum number of subjects on whom the criterion variable had been obtained. Table 2 also contains similar information for the criterion variables collected in 1956 and 1957, and used in the original study.
