Evidence for the factorial, convergent and discriminant, and criterion
-related validity of the Metacomprehension Scale (MCS) was examined in
a sample of 237 young adults. The instrument was factorially heteroge
neous but exhibited homogeneity within each of the seven subscales. Ev
idence for the convergent and discriminant validity of the MCS was exa
mined by correlating the subscales from the MCS with subscales from me
tacognitive questionnaires measuring similar constructs from related d
omains. In general, correlations within constructs were larger than co
rrelations between constructs, providing preliminary evidence of the c
onvergent and discriminant validity of the MCS. The criterion-related
validity of the MCS relative to other metacognitive measures was exami
ned by using the metacognitive measures and the MCS to predict compreh
ension performance. The MCS predicted performance better than the othe
r measures of metacognition and accounted for variance in performance
not accounted for by the other measures. These results show promise fo
r the value of self-assessments of metacomprehension. (C) 1997 Academi
