On the basis of metamemory assessment research and theories of discour
se comprehension, the Metacomprehension Scale (MCS) was designed to as
sess multiple dimensions of metacomprehension. In a sample of younger
(n = 30) and older (n = 30) adults, we examined age differences in sel
f-assessed components of metacomprehension and the relation of the MCS
to comprehension performance and general verbal ability. Younger adul
ts reported greater use of strategies to resolve comprehension failure
s (i.e., regulation) and placed higher value on good comprehension ski
lls than older adults. The MCS revealed a substantial amount of varian
ce in comprehension performance and verbal ability, with the regulatio
n dimension of metacomprehension being a reliable and consistent predi
ctor of performance. The results provided support for domain-specific
assessment of metacognition and for the critical role of regulation in
comprehension performance.
