Specific effects of word decoding, vocabulary and listening comprehension abilities on the development of reading comprehension were longitudinally examined for a representative sample of 2143 Dutch children throughout the elementary school period. An attempt was made to test two theoretical frameworks for the prediction of the development of reading comprehension: the lexical quality hypothesis in which word decoding and vocabulary are assumed to be critical determinants of reading comprehension and the simple reading view in which reading comprehension is assumed to be the product of word decoding and listening comprehension. The results showed significant progress across grades on all of the predictor and criterion measures. The stability of the measures was also high across time, which shows the individual differences between students to remain across grades. Word decoding exerted a substantial effect on early reading comprehension and a small effect on later sixth grade reading comprehension. The data provide empirical support for the lexical quality hypothesis as they show knowledge of word forms and word meanings (i.e. vocabulary) to predict the development of reading comprehension. Support for the simple reading view was also found in that word decoding and listening comprehension significantly predicted reading comprehension as well. A combined structural model with word decoding, vocabulary and listening comprehension as predictors of reading comprehension showed a substantial impact of the three predictors on reading comprehension at first grade. In subsequent grades, vocabulary is still predicting reading comprehension directly whereas listening comprehension shows a reciprocal relationship with vocabulary.

This study is one of the first to examine associations between alcohol-specific socialization and adolescents' drinking using a between- and a within-family design. Results showed strong associations between alcohol-specific socialization (particularly of enforcing rules) and adolescent alcohol use. Although parents strongly differentiated their socialization practices between children, no differences in associations between alcohol-specific socialization and drinking were found between older and younger adolescents.

In the Simple View of Reading proposed by Hoover and Gough (1990), reading comprehension is conceived as the product of word decoding and listening comprehension. It is claimed that listening comprehension or the linguistic processes involved in the comprehension of oral language strongly constrain the process of reading comprehension. In several studies, evidence for this theoretical framework has been provided for first language learners. In the present study, an attempt was made to find empirical evidence for the same view underlying second language reading. Therefore, the word decoding and listening comprehension skills of samples of 1,293 first language (L1) learners and 394 second language (L2) learners of Dutch were related to their reading comprehension abilities throughout the primary grades. It was found that the levels of word decoding were more or less equal in the two groups of learners, whereas the L2 learners stayed behind their first L1 peers in both listening, and reading comprehension. The relationships between word decoding, listening comprehension and reading comprehension turned out to be highly comparable. A longitudinal analysis of data showed the Simple View of Reading to be equally valid for L1 and L2 learners. With progression of grade, the impact of word decoding on reading comprehension decreased, whereas the impact of listening comprehension showed an increase to the same extent in the two groups of learners. However, the reciprocity of the relationship between listening comprehension and reading comprehension tended to be less prominent in the group of L2 learners.
