The internal/external frame of reference (I/E) model by Marsh (e.g., 1990a)
assumes two central information sources for the constitution of domain-spe
cific academic self-concepts: (1) social comparisons (external frame of ref
erence). in which students compare their own achievements with those of the
ir classmates; and (2) intraindividual comparisons (internal frame of refer
ence), in which students compare their own achievements in one subject with
their achievements in other subjects. In path analyses, it has been found
that the latter type of comparison leads to negative paths From achievement
indicators in subject A to self-concept measures in subject B. To investig
ate the actual impact of achievement feedback and of the frames of referenc
e on changes in self-concept variables, we analyzed math and German self-co
ncepts immediately following the announcement of exam results in each subje
ct. Participants were 258 7th- to 9th-graders. Path analyses using structur
al equation modeling supported the validity of the I/E model with respect t
o the impact of simultaneously given current exam results. In particular, G
erman achievement had a negative impact on subsequent math self-concept. (C
