Sex differences in domain-specific depressogenic cognitive responses to negative and positive life events

Maladaptive cognitive responses to stressful life events represent well-replicated risk factors for depression. Research indicates that stressful life events that are dependent on the individual to occur or are interpersonal may generate more maladaptive cognitive responses than those that are independent and/or non-interpersonal. The current study examined the roles of sex and life event domains in eliciting depressogenic cognitive responses. Participants were 212 (71% female) undergraduate students who completed seven weekly questionnaires on participant-identified most negative and most positive life events over the previous 7 days. Additionally, participants reported levels of brooding and cognitive style in response to the most negative event and levels of positive rumination and dampening in response to the most positive event. Data were analyzed using mixed ANOVAs. Results indicated that females engaged in greater brooding regardless of event dependency. In addition, dependent and interpersonal life events generated greater brooding while dependent and non-interpersonal negative events generated greater negative cognitive style. An interaction between sex and domain was observed for dampening positive life events, such that males did not differ between interpersonal and non-interpersonal life events while females were more likely to dampen following interpersonal life events than non-interpersonal events.     

The differential impact of brooding and reflection on the relationship between perceived stress and suicide ideation

This study investigated whether brooding and reflection moderated the relationship between perceived stress and suicide ideation. It was hypothesized that brooding, but not reflection, would strengthen the effect of perceived stress on suicide ideation above and beyond depression symptoms. Hypotheses were supported. Results suggest the assessment of a brooding response style may help identify clients who are more likely to contemplate suicide when confronted with life stress.
