The effects of rumination on the timing of maternal and child negative affect.

The current study examined whether rumination serves as a moderator of the temporal association between maternal and child negative affect. Participants included 88 mothers with a history of major depressive episodes and their 123 children. During an initial assessment, mothers and their children completed measures assessing negative affect and children completed a measure assessing the tendency to ruminate in response to such symptoms. Every 6 weeks for the subsequent year, mothers and their children completed measures assessing negative affect. Consistent with hypotheses, children with a ruminative response style were more likely than other children to report elevations in negative affect when their mothers' level of negative affect increased over time. Neither child gender nor mothers' current clinical depression status moderated the association between child rumination and maternal negative affect.

A test of the integration of the hopelessness and response styles theories of depression in middle adolescence.

The current study examined several theories of depression in a sample of middle adolescents. At Time 1, 367 ninth graders completed measures assessing depressogenic inferential styles, the tendency to ruminate in response to depressed mood, and depressive symptoms. Six weeks later, participants completed measures assessing negative events and depressive symptoms. In line with the hopelessness theory, a depressogenic weakest link interacted with negative events to predict increases in hopelessness depression symptoms but not in more general depressive symptoms. Further, providing partial support for the response styles theory, the tendency to ruminate in response to depressed mood predicted increases in hopelessness depression symptoms but not in more general depressive symptoms. Contrary to the integrative theory, the relationship between a depressogenic weakest link and increases in hopelessness depression symptoms following negative events was not moderated by a ruminative response style.

Multi-wave prospective examination of the stress-reactivity extension of response styles theory of depression in high-risk children and early adolescents.

The current study tested the stress-reactivity extension of response styles theory of depression (Nolen-Hoeksema Journal of Abnormal Psychology 100:569-582, 1991) in a sample of high-risk children and early adolescents from a vulnerability-stress perspective using a multi-wave longitudinal design. In addition, we examined whether obtained results varied as a function of either age or sex. During an initial assessment, 56 high-risk children (offspring of depressed parents; ages 7-14) completed measures assessing rumination and depressive symptoms. Children were subsequently given a handheld personal computer which signalled them to complete measures assessing depressive symptoms and negative events at six randomly selected times over an 8-week follow-up interval. In line with hypotheses, higher levels of rumination were associated with prospective elevations in depressive symptoms following the occurrence of negative events. Sex, but not age, moderated this association. Rumination was more strongly associated with elevations in depressive symptoms following the occurrence of negative events in girls than in boys.

Cognitive vulnerability to depressive symptoms in adolescents in urban and rural Hunan, China: a multiwave longitudinal study.

The current multiwave longitudinal study examined the applicability of two cognitive vulnerability-stress models of depression-Beck's (1967, 1983) cognitive theory and the hopelessness theory (Abramson, Metalsky, & Alloy, 1989)-in two independent samples of adolescents from Hunan Province, China (one rural and one urban). During an initial assessment, participants completed measures assessing dysfunctional attitudes (Beck, 1967, 1983), negative cognitive style (Abramson et al., 1989), neuroticism (Costa & McCrae, 1992), depressive symptoms, and anxiety symptoms. Once a month for the subsequent 6 months, participants completed measures assessing the occurrence of different types of negative events, depressive symptoms, and anxiety symptoms. Results provided support for cognitive vulnerability factors as predictors of increases in depressive symptoms following the occurrence of higher than average levels of negative events in Chinese adolescents. The results also supported the specificity of these two cognitive vulnerability factors as predictors of depressive versus anxiety symptoms following the occurrence of higher than average levels of negative events (i.e., symptom specificity), and the ability of cognitive vulnerability factors to predict prospective change in depressive symptoms above and beyond the effects of trait neuroticism (i.e., etiological specificity).
