    Prevention of reading difficulties in children with and without familial risk:Short- and long-term effects of an early intervention

    In a randomized-controlled trial we tested a computer-assisted intervention for the prevention of reading difficulties, delivered by nonprofessional tutors, running from kindergarten to halfway Grade 2. The full sample included 123 prereaders (M = 5; 6 years; 56 intervention; 67 controls) with low preliteracy skills. Parents were sent a questionnaire to assess family risk (FR) for reading difficulties. There was no intervention effect in the full sample, but, unexpectedly, the effect differed between subsamples that did and did not return the questionnaire. The intervention did not affect reading acquisition in the subsample (N = 49) without FR-data, mostly children from immigrant, non-Dutch speaking, low-socioeconomic status (SES) families, but had large effects in the subsample of Dutch-speaking, middle and high SES-parents with FR-data (N = 74). The latter subsample was followed until Grade 6, 4 years after the intervention, and included 36 intervention children and 38 controls. Long-lasting improvements were found in word-reading fluency, which transferred to reading fluency for pseudowords, English words: and texts, and to spelling. The intervention substantially reduced the need for remedial teaching and grade retention. On all measures, children with FR performed worse than children without FR. The intervention had similar effects on the progress of both groups, but the FR children needed more sessions. This study shows that a 2-year cost-effective early intervention can reduce the incidence of reading difficulties. However, it remains a challenge to make the intervention suited for children in which a lack of preliteracy skills merely seems to reflect a lack of learning opportunities

    Pathways Into Literacy:The Role of Early Oral Language Abilities and Family Risk for Dyslexia

    The present study investigated the role of early oral language and family risk for dyslexia in the two developmental pathways toward reading comprehension, through word reading and through oral language abilities. The sample contained 237 children (164 at family risk for dyslexia) from the Dutch Dyslexia Program. Longitudinal data were obtained on seven occasions when children were between 4 and 12 years old. The relationship between early oral language ability and reading comprehension at the age of 12 years was mediated by preliteracy skills and word-decoding ability for the first pathway and by later language abilities for the second pathway. Family risk influenced literacy development through its subsequent relations with preliteracy skills, word decoding, and reading comprehension. Although performance on language measures was often lower for the family-risk group than for the no-family-risk group, family risk did not have a specific relation with either early or later oral language abilities

    Predictors for grade 6 reading in children at familial risk of dyslexia

    Get PDF
    The present study investigates whether grade 6 reading outcomes, reading fluency, and reading comprehension can be predicted by grade 3 reading fluency, familial risk of dyslexia (FR), and grade 3 reading related skills: rapid automatized naming (RAN), phonological awareness (PA), and vocabulary. In a sample of 150 children, of whom 83 had a parent with dyslexia, correlation and regression analyses were performed. FR, measured on a continuous scale, was by itself related to all outcomes. However, FR did not explain any variance on top of grade 3 reading fluency. Grade 3 reading fluency strongly predicted grade 6 reading fluency and was also related to reading comprehension. RAN improved the prediction of grade 6 reading fluency, though the additional explained variance was small. Vocabulary and PA fully explained the variance that grade 3 reading fluency explained in grade 6 reading comprehension. Vocabulary explained a substantial amount of variance in grade 6 reading comprehension making it an interesting clinical target. As we used continuous measures of reading fluency and FR, our findings are not biased by distinct diagnostic criteria

    Acquiring reading and vocabulary in Dutch and English: the effect of concurrent instruction

    Get PDF
    To investigate the effect of concurrent instruction in Dutch and English on reading acquisition in both languages, 23 pupils were selected from a school with bilingual education, and 23 from a school with education in Dutch only. The pupils had a Dutch majority language background and were comparable with regard to social-economic status (SES). Reading and vocabulary were measured twice within an interval of 1 year in Grade 2 and 3. The bilingual group performed better on most English and some of the Dutch tests. Controlling for general variables and related skills, instruction in English contributed significantly to the prediction of L2 vocabulary and orthographic awareness at the second measurement. As expected, word reading fluency was easier to acquire in Dutch with its relatively transparent orthography in comparison to English with its deep orthography, but the skills intercorrelated highly. With regard to cross-linguistic transfer, orthographic knowledge and reading comprehension in Dutch were positively influenced by bilingual instruction, but there was no indication of generalization to orthographic awareness or knowledge of a language in which no instruction had been given (German). The results of the present study support the assumption that concurrent instruction in Dutch and English has positive effects on the acquisition of L2 English and L1 Dutch

    Dutch home-based pre-reading intervention with children at familial risk of dyslexia

    Get PDF
    Children (5 and 6 years old, n = 30) at familial risk of dyslexia received a home-based intervention that focused on phoneme awareness and letter knowledge in the year prior to formal reading instruction. The children were compared to a no-training at-risk control group (n = 27), which was selected a year earlier. After training, we found a small effect on a composite score of phoneme awareness (d = 0.29) and a large effect on receptive letter knowledge (d = 0.88). In first grade, however, this did not result in beneficial effects for the experimental group in word reading and spelling. Results are compared to three former intervention studies in The Netherlands and comparable studies from Denmark and Australia
