Problem: Little research has been done with children to determine effects of using various patterns of anger expression on trait anger. The purpose was to examine differences in trait anger of children who indicated high, moderate, or low use of three patterns of anger expression. Methods: A convenience sample of 1,060 third through sixth graders completed trait anger and patterns of expressing anger instruments. Findings: High users of anger-out (anger expressed outwardly) had the highest trait anger for every grade while high users of angerreflection/ control had the lowest. Conclusions: Anger-reflection/control may be more effective than anger-out in reducing trait anger in school-age children.
