Bidirectional relations between text reading prosody and reading comprehension in the upper primary school grades: A longitudinal perspective

The purpose of this study was to examine the directionality of the relationship between text reading prosody and reading comprehension in the upper grades of primary school. We compared 3 theoretical possibilities: Two unidirectional relations from text reading prosody to reading comprehension and from reading comprehension to text reading prosody and a bidirectional relation between text reading prosody and reading comprehension. Further, we controlled for autoregressive effects and included decoding efficiency as a measure of general reading skill. Participants were 99 Dutch children, followed longitudinally, from 4th to 6th grade. Structural equation modeling showed that the bidirectional relation provided the best fitting model. In 5th grade, text reading prosody was related to prior decoding and reading comprehension, whereas in 6th grade, reading comprehension was related to prior text reading prosody. As such, the results suggest that the relation between text reading prosody and reading comprehension is reciprocal but dependent on grade level
