Sex differences and response styles: subtypes of rumination and associations with depressive symptoms.

In view of recent findings regarding the multifaceted nature of rumination in adults and older adolescents, the purpose of this study was to evaluate the construct of rumination as a 2-factor model (brooding and reflection) in a child and early adolescent sample as well as examine sex differences and associations between depressive symptoms and these ruminative subtypes. Participants were children in 2nd through 7th grades (N = 303). Results of a confirmatory factor analysis supported the hypothesis that subtypes of rumination (2-factor model) are present in children and provided a better fit than a unitary construct of rumination (1-factor model). As predicted, girls endorsed higher levels of brooding than boys, and brooding (not reflection) was uniquely related to depressive symptoms. Results revealed that a distinction between brooding and reflection subtypes is warranted as it can help lead to better assessment and identification of risk factors of depression.
