Listening comprehension is important for daily communication and at school, yet relatively little is known about the variables contributing to listening comprehension, especially in the upper elementary years. The aim of this study was to explore whether vocabulary, verbal memory, but also self-efficacy and self-reported concentration contribute to listening comprehension. The authors assessed oral text comprehension, as well as the concurrent contributors vocabulary, verbal short- and long-term memory, self-efficacy and concentration in a sample of 442 upper elementary school children (9- to 12-year-olds). Structural equation models were used to test for direct and indirect associations. The best-fitting model was an indirect model in which verbal short-term memory and self-efficacy were positively associated with children's vocabulary. Vocabulary, in turn, was positively associated with children's listening comprehension. Using bias-corrected bootstrap procedures, however, vocabulary appeared to mediate the association between academic self-efficacy and listening comprehension. The indirect association between verbal short-term memory and listening comprehension through vocabulary just missed significance. The findings relate to models of listening comprehension that state a dominant role for vocabulary, also in the upper elementary years. They imply that the models could extend to evaluating broader student-related resources, such as academic self-efficacy. Furthermore, the findings on general cognitive resources fit the pattern of mixed findings in previous research. Together, the results motivate further research into contributors to listening comprehension throughout the elementary years.
