Perfectionism and longitudinal patterns of stress for STEM majors: Implications for academic performance.

Complementary hypotheses suggest that perfectionism may (a) cause later stress (stress generation) and (b) moderate the effects of stress on subsequent outcomes (stress enhancement). The present study tested these hypotheses with a sample of 432 first-time college freshmen pursuing science, technology, engineering, and math (STEM) majors. Students completed baseline perfectionism scales and repeated measures for perceived academic stress at...
