Personality and psychopathology have long been associated; however, the mechanisms that account for this link are not well
understood. Stress generation and cognitive vulnerability are examined as potential mechanisms to explain the association
between negative emotionality and dysphoria. To evaluate these mechanisms, college students completed measures of personality,
dysfunctional attitudes,

reported on the occurrence of negative events and levels of dysphoric symptoms that they had experienced over the 2-year follow-up
period. Consistent with hypotheses, negative emotionality predicted prospective increases in dysphoric symptoms and the generation
of more stressors over time. Both dysfunctional attitudes and negative cognitive style interacted with these additional stressors
to predict prospective elevations in dysphoria, and these cognitive vulnerability–stress components partially mediated the
association between negative emotionality and future elevations of dysphoric symptoms.
