Although a child's early academic abilities have been shown to predict later adult outcomes, the importance of non-academic skills and behaviors cannot be ignored. This study aimed to focused on three such constructs, internalizing behaviors, externalizing behaviors, and working memory abilities, in a large, nationally representative dataset, the Early Childhood Longitudinal Study-Kindergarten Class of 2011, which followed children (N = 18,170) longitudinally from kindergarten through fifth grade. Further, this study aimed to determine if disability status (N = 3,160) or English language learner status (n = 470) were predictive of a child's trajectory, and if trajectory membership predicted both academic and non-academic outcomes in fifth grade.
Both growth mixture modeling (GMM) and hierarchal linear modeling (HLM) approaches were used to compared modeling approaches and determine if they provide converging evidence. Using GMM, this study replicated the results seen by Nivard and colleagues (2017) regarding externalizing trajectories but found different trajectories of internalizing behaviors. Additionally, exploratory analyses using GMM found six groups of working memory trajectories. Consistent with the hypotheses of this study, disability status was found to significantly predict group trajectories for all three constructs (internalizing behaviors, externalizing behaviors, and working memory abilities). However, ELL status only significantly predicted working memory group membership, and this did not appear to be driven by socioeconomic status. Overall, GMM and HLM displayed converging evidence regarding which demographic characteristics are predictive of a child's trajectory throughout elementary school.
Also, in line with hypotheses, when compared to internalizing/externalizing behaviors, differences in working memory group membership were associated with larger differences in academic scores, but smaller differences in school belongingness and grit. Ov (open full item for complete abstract)
