Data from 2,655 children in Grades 1 to 3 and their teachers were analyzed. Children completed SDQ-Kids, previously piloted (n = 896), while teachers completed SDQ-T. Reliability was measured using Cronbach{\textquoteright}s alpha, and logistic regression analyzed the association between rating source (teachers vs. children) and SDQ status (“abnormal” vs. “normal”). Validity was assessed using Pearson{\textquoteright}s correlation coefficient. SDQ-Kids showed acceptable internal consistency for total difficulties (α =.77) but lower for subscales (α =.40–.68). SDQ-T reliability was good for total difficulties (α =.90) and acceptable to good for subscales (α =.78–.89). Differences emerged, particularly in internalizing and externalizing problems. Correlations of SDQ-Kids with other instruments were acceptable to low. Differences between teacher and child reports highlight the need for a multi-informant approach. While SDQ-Kids{\textquoteright} total difficulties showed acceptable reliability, scale-level reliability and validity were unsatisfactory.",
