This research aimed at investigating the influence of middle school students’ internal and external locus of control,
adaptive and maladaptive emotional regulation strategy on test anxiety, and verifying whether the effect of internal
and external locus of control on test anxiety is regulated by cognitive emotional regulation strategy. For this, this
research analyzed the data by conducting a test targeting total 421 students of middle school students in Seoul and
Gyeonggi-do. The research results are as follows. First, internal and external locus of control did not show a
significant relation with test anxiety, and no correlation with other strategies besides rumination and catastrophizing
related to maladaptive cognitive emotional regulation strategies. On the other hand, internal and external locus of
control showed significant static relation with adaptive cognitive emotional regulation strategy. Test anxiety did not
show a significant correlation with adaptive cognitive emotional regulation strategy, however significant static
correlation with maladaptive emotional regulation strategy. Second, while internal and external locus of control did not
have a significant influence on anxiety factor, the subordinate factor of test anxiety, however displayed a significant
tendency on emotional factor among the subordinate factors of test anxiety. Therefore, internal and external locus of
control has a tendency to predict emotion among the test anxiety, which implies that emotional aspect among test
anxiety is inclined to decrease in the emotional aspect among test anxiety while internal sense of control appeared
more. Third, the influence of internal and external locus of control on test anxiety was significantly regulated. That is,
test anxiety decreased when there’s more internal sense of control by well using adaptive cognitive emotional regulation
strategy. On the other hand, maladaptive cognitive emotional control strategy in the relation between the internal and
external locus of control and test anxiety did not appear as the regulation factor between internal and external locus
of control and test anxiety. In conclusion, middle school students’ internal and external locus of control and cognitive
emotional regulation strategy influenced test anxiety, and the negative influence of internal and external locus of
control on test anxiety appeared relieved while adaptive cognitive emotional regulation strategy was utilized more.
