This article suggests that counselors measure vocational interests by
using three interest inventories: the Ramak Interest Inventory, the Co
urses Interest Inventory, and the Self-Directed Search (Holland, 1985)
. Some implications from studies on (a) vocational congruence, (b) env
ironmental congruence, (c) the structure of occupational fields and (d
) within-occupation congruence are discussed. Five defense mechanisms
for clients who happen to be in an incongruent occupation or environme
nt are presented.
