An Evaluation of Gender Differences in Self-Reported Internalizing Symptoms of Elementary-Age Children

Abstract

Gender differences in self-reported internalizing symptoms of children in grades 3-6 were investigated. Using the Internalizing Symptoms Scale for Children (ISSC), and normative data from a large, nationwide sample, self-reported internalizing symptom scores of boys (n = 876) were compared to those of girls (n = 840). Total internalizing scores of girls were significantly (p < .001) larger than those of boys, indicating a higher degree of self-reported internalizing symptoms. The average scores of the girls were approximately one third of a standard deviation higher than the average scores of the boys. Using a discriminant function analysis, the ISSC item scores were found to be reasonably effective in classifying subjects by gender. Seven critical self-report items that contributed the most to the separation of subjects by gender were identified. Implications of this study for psychoeducational assessment practice, early identification of internalizing problems, and subsequent intervention efforts are discussed.
