To reduce the number of analyses, we created composite scores (within-reporter) equal to the average of the T1 and T3 measure of temperament. The average within-reporter correlation for the regulation/impulsivity measures was .53 (ranged from .35 to .72). Parents’ and teachers’ reports of anger were significantly related within reporter between T1 and T3, rs(212) = .57 and .20, ps < .01, for parents and teachers, respectively. However, reports from T1 to T3 of sadness were only significantly correlated across time for parents, rs(212) = .53 and .01, p < .01 and ns, for parents and teachers, respectively. In addition, for each measure of temperament except sadness, the pattern of findings for the combined measures was very similar to the pattern found when T1 and T3 measures were used separately. These composites (except for sadness) were used for findings presented in Tables 4 and 5 but not in other analyses.
