Effects of Angry Rumination and Distraction in Intimate Partner Violent Men

Although the tendency to ruminate is related to the frequency of intimate partner violent (IPV) perpetration, it is unclear how IPV men react emotionally and physiologically during angry rumination. This study is the first to experimentally manipulate rumination and distraction with violent men. Using the rumination and distraction paradigm developed by Nolen-Hoeksema and Morrow, IPV (N = 87) and nonviolent (NV; N = 30) men underwent an anger induction and then were randomly assigned to either ruminate or distract. IPV men were hypothesized to experience increased effects of rumination compared to NV men. As predicted, the results demonstrate an increase in heart rate from baseline to postrumination. No change in physiological arousal was observed in the distraction condition over time. Surprisingly, no difference state anger was found between IPV and NV men, and both conditions resulted in an increase in state anger. Implications for battering interventions suggest that distraction strategies, such as taking a time-out, are not sufficient to decrease physiological arousal. Intervention strategies that address mindfulness, physiological soothing, distorted cognitions, and rumination may be more powerful in decreasing negative physiological arousal among IPV men.

The role of rumination in illness trajectories in youth: linking trans-diagnostic processes with clinical staging models

Research in developmental psychopathology and clinical staging models has increasingly sought to identify trans-diagnostic biomarkers or neurocognitive deficits that may play a role in the onset and trajectory of mental disorders and could represent modifiable treatment targets. Less attention has been directed at the potential role of cognitive-emotional regulation processes such as ruminative response style. Maladaptive rumination (toxic brooding) is a known mediator of the association between gender and internalizing disorders in adolescents and is increased in individuals with a history of early adversity. Furthermore, rumination shows moderate levels of genetic heritability and is linked to abnormalities in neural networks associated with emotional regulation and executive functioning. This review explores the potential role of rumination in exacerbating the symptoms of alcohol and substance misuse, and bipolar and psychotic disorders during the peak age range for illness onset. Evidence shows that rumination not only amplifies levels of distress and suicidal ideation, but also extends physiological responses to stress, which may partly explain the high prevalence of physical and mental co-morbidity in youth presenting to mental health services. In summary, the normative developmental trajectory of rumination and its role in the evolution of mental disorders and physical illness demonstrates that rumination presents a detectable, modifiable trans-diagnostic risk factor in youth.

Interpersonal Orientation in Context: Correlates and Effects of Interpersonal Complementarity on Subjective and Cardiovascular Experiences

Interpersonal orientation (IO) generally refers to individual differences in preference for social interaction. The influence of IO, however, likely depends on the nature of complementarity within the interpersonal context. Using the interpersonal circumplex and Five-Factor Model, we first selected a measure of IO characterized by affiliation and neuroticism. Second, we examined the influence of IO on subjective, physiological, and nonverbal experiences as a function of experimentally manipulated complementarity or noncomplementarity. We hypothesized that women in noncomplementarity conditions (i.e., women low in IO working with a friendly confederate, women high in IO working with an unfriendly confederate) would experience the interpersonal situation more negatively compared to women in complementarity conditions. Study results confirmed this prediction, with noncomplementarity in IO resulting in greater physiological reactivity, greater likelihood to attempt nonverbally to restore complementarity, more partner-related thoughts, and a reduced desire to seek out attention compared to women working in complementarity conditions. Implications for research on IO as a person variable are discussed.
