A Retrospective Longitudinal Study of Cognitive and Language Skills in Poor Reading Comprehension
- 2014
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Fifty-six specific poor reading comprehenders (SPRC) were selected in grade 4 and retrospectively compared to good comprehenders at preschool age 5 and at the end of kindergarten, grade 1 and 2. The results showed a widespread language-deficit profile in children with SPRC, including deficits in vocabulary, grammar, verbal memory and early phonological awareness in a large part of the sample beginning in preschool. The reading comprehension deficits in children with SPRC were not as apparent in earlier assessments at grade 1 and 2, likely because of the greater dependence on word decoding in reading comprehension in the early grades.

Early Predictors of Reading Comprehension Difficulties
- 2014

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of the present thesis was to examine the cognitive and language profile in children with poor reading comprehension using a longitudinal perspective. Even though comprehension skills are closely connected to educational success, comprehension deficits in children have been neglected in reading research. Understanding factors underlying reading is important as it improves possibilities of early identification of children at risk of developing reading problems. In addition, targeted interventions may prevent or reduce future problems. Descriptions of the cognitive and language profile in children with different types of reading problems from an early age and over time is an important first step.The three studies included in this thesis have been conducted using data from the International Longitudinal Twin Study (ILTS). In the ILTS, parallel data have been collected in the US, Australia, Sweden and Norway. Altogether, more than 1000 twin pairs have been examined between the ages 5 and 15 years using well known predictors of reading, along with decoding, spelling, reading comprehension and oral language measures.In the three studies, the Simple View of Reading has been used as a theoretical framework and children who exhibited different kinds of comprehension related difficulties have been identified at different ages. The studies include both retrospective and prospective analyses. The results across studies indicated a robust oral language deficit in all subtypes displaying comprehension problems. The oral language deficit was widespread and included vocabulary, grammar and verbal memory. In addition, the oral language deficit was manifested as compromised phonological awareness and print knowledge prior to reading instruction. Reading comprehension deficits were late emerging across studies in children with comprehension difficulties.

Tidskriftsartikel (refereegranskat)abstract
- Two groups of fourth-grade children were selected from a population sample (N = 926) to be either poor oral comprehenders (poor oral comprehension but normal word decoding) or poor decoders (poor decoding but normal oral comprehension). By examining both groups in the same study with varied cognitive and literacy predictors, and examining them both retrospectively and prospectively, we could assess how distinctive and stable the predictors of each deficit are. Predictors were assessed retrospectively at preschool and at the end of kindergarten, Grade 1, and Grade 2. Group effects were significant at all test occasions, including those for preschool vocabulary (worse in poor oral comprehenders) and rapid automatized naming (RAN) (worse in poor decoders). Preschool RAN and vocabulary prospectively predicted Grade 4 group membership (77–79% correct classification) within the selected samples. Reselection in preschool of “at-risk” poor decoder and poor oral comprehender subgroups based on these variables led to significant but relatively weak prediction of subtype membership at Grade 4. Implications of the predictive stability of our results for identification and intervention of these important subgroups are discussed.

Pattern of Preschool Prediction of Reading Comprehension Impairment : A 10 Year Longitudinal Study
- 2014
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Compromised reading comprehension will invariably influence future academic achievements. In reading research there has been an emphasis on early identification of poor decoders to reduce future difficulties. Only a few studies have examined preschool prediction of reading comprehension impairments beyond the first grades of school, and these studies have presented different patterns of results. As studies have mostly been conducted in English; it is unclear how the results generalize to languages with transparent orthographies. In this study, a Swedish and a Norwegian twin sample were used to predict reading comprehension and decoding impairments in grade 2, 4 and 8/9 from preschool. The results suggested an important role for RAN and verbal memory. Compromised RAN was consistently associated with the poor decoders, as well as in identifying poor reading comprehenders in grade 8/9. Verbal memory tasks at preschool contributed to the identification of children with reading comprehension impairment across grades.
