Effects of abstract versus concrete rumination about anger on affect

Background:The processing-mode theory of rumination proposes that an abstract mode of rumination results in more maladaptive consequences than a concrete ruminative mode. It is supported by evidence mostly from the area of depression and little is known of the relative consequences of abstract versus concrete rumination for anger. Aims:We investigated the differential effects of abstract versus concrete rumination about anger on individuals' current affect. We hypothesized that abstract rumination would increase current anger and negative affect, and decrease positive affect, to a greater extent than concrete rumination. Method:In a within-subject design, 120 participants were instructed to focus on a past social event that resulted in intense anger and then to ruminate about the event in both an abstract and a concrete mode, in a randomly assigned order. Current anger, negative and positive affect were assessed before and after each rumination phase. Results:Anger and negative affect increased and positive affect decreased from pre- to post-rumination. Contrary to expectations, these patterns were observed irrespective of the ruminative mode induced. Conclusions:This initial study does not support the hypothesis that abstract and concrete rumination about anger have different consequences for current affect. Replications and more extensive designs are needed.
