Depression and depressive symptoms in preschool children from the general population.

This multiphasic study used four independent sources of information to investigate depression and depressive symptoms in a sample of preschool-age children from a general population. The study provides evidence that major depressive disorder exists in preschoolers and that stressful life events are associated with depressive symptoms; it underscores the importance of the teacher's report for identifying the presence of depression in this age group. Details of the findings, including a new scale for rating depression in young children, are discussed.
