title: How is anxiety involved in the longitudinal relationship between brooding rumination and depressive symptoms in adolescents?
abstract: A growing body of research supports the application of Response Styles Theory to adolescent populations. Although the essential dynamic, namely that rumination increases the incidence of depressive symptoms, has been demonstrated among adolescents, a number of important empirical questions remain, such as: what are the gender differences and developmental trends for brooding and reflective rumination?; does a reciprocal relationship exist between brooding or reflective rumination, on the one hand, and depressive symptoms and anxiety, on the other hand, over time? and how do additional variables (i.e., anxiety) impact upon the rumination-depressive symptoms relationship? In this study, self-reported levels of rumination (both brooding and reflective), and anxious and depressive symptoms were measured longitudinally across 4 months in a sample of 976 community adolescents (46% females), aged 11-16 years old. Mean group differences showed that female adolescents reported engaging in more brooding rumination than male adolescents beginning at 13 years of age. A reciprocal brooding rumination to depressive symptoms relationship and a reciprocal brooding rumination to anxiety relationship were found over time, and they did not differ for boys and girls. We tested the possibility that anxious symptoms would function as a third variable, but the obtained model showed that brooding rumination and anxiety both contributed unique variance in predicting changes in depressive symptoms over time.
