Introduction: The present study examined the influence of personal standards and self-critical perfectionism on depressive and anxiety symptoms over the academic year. Methods: High-school students (N = 174) were surveyed in the late Fall and early Spring, assessing perfectionism in the Fall and mental health across the year in both the Fall and Spring. Path modelling was used to examine whether self-critical and personal standards perfectionism were related to changes in mental health across the school year. Results: Controlling for mental health at the start of the year, self-critical perfectionism predicted an increase in depressive symptoms over time, whereas personal standards perfectionism was unrelated to changes in mental health. Discussion: Results support that self-critical perfectionism is detrimental to mental health in adolescents, suggesting that future interventions should focus on reducing self-critical cognitive biases in youth.
