Adolescent depression is serious and common. As adolescents spend approximately 15,000 h in school, this setting is a logical place to seek etiological factors. Research suggests there are negative associations between school climate and adolescent depressive symptoms. However, such studies typically use student reports of both climate and depressive symptoms; this is problematic because common method variance results when the same individual provides information on all variables, contributing to overestimations of associations between depressive symptoms and school climate. Therefore, the purpose of this study is to examine the association between teacher-reported school climate and adolescent-reported depressive symptoms. Thus, 2545 Australian …

Background: The objective of this study is to test Davidson’s, and Heller and Nitschke’s models stating cortical activity in adolescents to be a marker for increased risk for depression.

Methods: Alpha activity was measured in 80 adolescents from medial-frontal (F3/4), lateral-frontal (F7/8), and medial-parietal (P3/4) electrodes, as well as self-reported depression and anxiety twice within 12 months. Stepwise hierarchical regression analyses with anxiety as covariate were calculated with alpha asymmetry as predicting variable and depression as target variable and vice versa.

Results: Independent of whether anxiety was used as covariate or not, frontal and parietal alpha asymmetry predict depression, but …
