These nine dimensions were derived by Gilbert, who used the Followership Effectiveness Assessment questionnaire consisting of 77 descriptors of a subordinate's behavior. The instrument was used with 828 executives, managers, and supervisors, each of whom applied it to one subordinate. Factor analysis identified the following crucial dimensions: overall followership, partnership with the boss, commitment to the job, technical competency, sense of humor, dependability, positive working relations, tendency to speak up, and proper comportment. The sworn officers of the Colorado State Patrol rated higher than average in six of the nine dimensions. High followership was correlated with performance excellence and promotability, but it did not necessarily correlate with the ratings received from the formal appraisal system. Findings indicate that officers aspiring to improved ratings and future promotion should assess their own followership status, because it is a learned ability and is critical to individual and organizational performance in police work.
