Based on 1,364 children across Grades 1, 3, and 5, the present study explored the mutualism of (externalizing and internalizing) behavioral problems and language, and whether social skills explained such mutualism. The random intercept cross-lagged panel models were conducted to control for between-person level variance and to explore mutualism of variables on the within-person level. Results indicated the mutualistic coupling of language and externalizing behavioral problems from Grades 3 to 5. When including social skills in the model, only social skills and externalizing behavioral problems formed the mutualism from Grades 3 to 5; language only predicted behavioral problems and social skills in the early elementary stage (Grades 1-3). These results suggest that language and behavioral management early on are important investing skills for the development of language, behavior skills, and social skills. With development, social skills may become more important than general language skills to manage problem behaviors. These findings indicated that interventions targeting behavioral problems may need to adapt their focus as children develop: fostering general language abilities early on but shifting to building social skills in later grades.
Educational Impact and Implications StatementThis work shows that language is important for social skills and behavioral management early on. With development, social skills become more important than language skills for managing behavioral problems. To target behavioral problems, it may be important to foster language abilities early on but shift to building social skills in later grades.
