The participants’ level of rational thinking and (stated) action, as well as attribution levels, were evaluated through written responses to anger-inducing scenarios. Rationality of stated actions increased for the overall group and 7th and 8th grade subgroups. Rationality of thinking remained stable for the overall group, increased for the 7th graders, and decreased for the 8th graders. Analysis of attribution data revealed mostly positive trends (toward more internal attributions for anger) for ability, luck, and task difficulty. Effort was the only attribution with a trend toward more external attributions, i.e., the participants did not respond that they would try harder to control their anger over the course of the training.
