The transition to high school coincides with an increase in the prevalence of depressive symptoms.A longitudinal intervention experiment involved three independent samples of students entering high school (N = 599). A brief self-administered reading and writing activity taught an incremental theory of personality, the belief that peopleÕs socially relevant characteristics have the potential to change. The intervention reduced the incidence of clinically significant levels of self-reported depressive symptoms 9 months postintervention by nearly 40% among adolescents assigned to the intervention condition, compared with control participants.
