Perfectionism in the transition to university: Comparing diathesis-stress and downward spiral models of depressive symptoms
Transitioning to university may be especially difficult for students who expect perfection from themselves. Self-critical perfectionism has consistently been linked to poor mental health. The current study compares a diathesis-stress and a downward spiral model, to determine why self-critical perfectionism is detrimental for mental health during this transition. First-year students (N=658) were recruited prior to beginning university in August and contacted again in October, January, and April. Participants completed measures on perfectionism, stress and depressive symptoms. Evidence was found for a downward spiral model with self-critical perfectionism, but not a diathesis-stress model. Students higher in self-critical perfectionism were more likely to experience increased stress and depressive symptoms in a circular and additive manner. Conversely, students higher in personal standards perfectionism experienced less stress and subsequent depressive symptoms. This research provides a theoretical model for why self-critical perfectionism is related to poor mental health outcomes which become sustained over time.
