A meta-analysis of 69 data sets ( N = 125,308) was carried out on studies that simultaneously evaluate the effects of math and verbal achievements on math and verbal self-concepts. As predicted by the internal/external frame of reference (I/E) model, math and verbal achievements were highly correlated overall (.67), but the correlation between math and verbal self-concepts (.10) was close to zero. Correlations between math and verbal achievement and correlations between achievements and self-concepts within the domains were more positive when grades instead of standardized test results were used as achievement indicators. A path analysis revealed support for the I/E model, with positive paths from achievement to the corresponding self-concepts (.61 for math, .49 for verbal) and negative paths from achievement in one subject to self-concept in the other subject (−.21 from math achievement on verbal self-concept, −.27 from verbal achievement to math self-concept). Furthermore, results showed that the I/E model is valid for different age groups, gender groups, and countries. The I/E model did not fit the data when self-efficacy measures were used instead of self-concept measures. These results demonstrate the broad scope of the I/E model as an adequate description of students’ self-evaluation processes as they are influenced by internal and external frames of reference.

Beside interindividual social comparisons, intraindividual dimensional comparisons in which students compare their achievements in one subject with their achievements in other subjects have an impact on their academic self-concepts. The internal/external frame of reference (I/E) model by Marsh (1986) assumes that dimensional comparisons lead to negative paths from achievement in one subject (e.g., math) to self-concept in another subject (e.g., English). In the present study, the I/E model was extended to two verbal domains (German as the native language and English as a foreign language) and two numerical domains (mathematics and physics). Grades and domain-specific academic self-concepts of N=1440 students from 63 classes were assessed. In support of the extended I/E model, (a) math, physics, German, and English achievement were positively correlated, as were; (b) self-concepts within the verbal and numerical domains, while; (c) self-concepts between the verbal and the numerical domains were almost uncorrelated; (d) positive paths were received from math, physics, German, and English achievement on the corresponding selfconcepts; (e) negative paths were found from achievement in one

Dimensional comparisons seem to be of particular importance for students with negative interdependence beliefs.

People not only use social comparisons to evaluate their abilities, they also engage in dimensional comparisons, comparing their own achievement in different domains. Processes of dimensional comparison have contrasting effects on subject-specific self-concepts: downward dimensional comparisons result in higher self-concept in the intraindividually better domain, whereas upward dimensional comparisons result in lower self-concept in the intraindividually weaker domain. Two field studies and 1 experimental study were conducted to investigate whether the effects of downward or upward dimensional comparisons are stronger. In Study 1 (N ϭ 319), downward dimensional comparisons proved to be stronger than upward dimensional comparisons. In Study 2 (N ϭ 1349), the same pattern was found with reading test scores as well as grades as achievement indicators. In Study 3 (N ϭ 81), the authors found larger effects for downward than for upward comparisons in both self-perceived competence and satisfaction with test outcomes in an experimental setting.
