Age and sex differences in beliefs about strategies for reducing parental anger were assessed. The central question was whether direct intervention strategies are the most effective for, and reflect more advanced understanding of, anger reduction. In Study 1, 120 children ages 4-9 years generated strategies they believed would lessen a parent's anger elicited by 3 situations of increasing complexity. Across ages children proposed direct intervention strategies for the simplest situation, and there was an age increase in suggesting direct intervention strategies for the more complex situations. In Study 2, 180 children, ages 4-12 years, and their parents rated the effectiveness of the strategies generated for the most complex situation (interparental argument). There was no longer a unilinear age increase in believing direct intervention strategies effective. Unlike with older and younger children, there was no agreement between 7-9-year-olds and their parents on the efficacy of direct intervention strategies.
