Abstract

Purpose

Researchers benefit from controlling for individual differences that systematically account for variance in acute cortisol responses (e.g., sex). Similarly, some suggest that education could be used as a cortisol covariate because prior work found a negative relationship between education and the magnitude of acute cortisol responses in middle-aged adults. Nevertheless, education is seldom controlled for in tests of cortisol responses to acute stress, in part because the effect of education on acute cortisol responses has yet to be tested in a college sample. The present study therefore tested the relationship between education and cortisol responses to acute stress in college students.

Method

Participants (124 healthy undergraduate students) self-reported education level and were subjected to a stressful speech task. Salivary cortisol was collected 0, + 15, + 25, + 40, and + 55 min post-stressor onset. Participant also completed a battery of questionnaires assessing individual differences, day-to-day demands, and stress-related appraisals.

Results

Students in their fourth year of college education or above had significantly less curvilinear responses to the stress task relative to first-, second-, and third-year students.

Conclusion

The effect of education on cortisol responses previously found in middle-aged adults was replicated in college students. Future research may therefore benefit from controlling for education when analyzing acute cortisol responses in college samples.
