<p>This paper investigates levels of depressive symptoms among older children and young adolescents, 11–14 years of age. The population-based sample was assessed twice during a 12-month period.

Introduction:
This paper investigates levels of depressive symptoms among older children and young adolescents, 11–14 years of age. The population-based sample was assessed twice during a 12-month period. Point-prevalence, 12-month prevalence, and 12-month incidence were measured by a validated self-reported scale (SFMQ) and are presented in this paper.

The population was assessed twice within one 12-month period resulting in 1439 participants at both data collection points. Depressive symptoms were measured by a validated self-reported scale, The Short Mood and Feelings Questionnaire (SMFQ).
