Following a review of the predictors of learning to read across languages, and the role of language skills as critical foundations for literacy, profiles of reading disorders are discussed and putative causal risk factors at the cognitive, biological, and environmental levels of explanation considered. Reading disorders are highly heritable and highly comorbid with disorders of language, attention, and other learning disorders, notably mathematics disorders. The home literacy environment, reflecting gene-environment correlation, is one of several factors that promote reading development and highlight an important target for intervention. The multiple deficit view of dyslexia (Cognition, 101, 2006, 385) suggests that risks accumulate to a diagnostic threshold although categorical diagnoses tend to be unstable. Implications for assessment and intervention are discussed.

Annual Research Review: The nature and classification of reading disorders – a commentary on proposals for DSM-5 / Margaret J. SNOWLING in Journal of Child Psychology and Psychiatry, 53-5 (May 2012)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 53-5 (May 2012) . - p.593-607 Titre : Annual Research Review: The nature and classification of reading disorders – a commentary on proposals for DSM-5 Type de document : Texte imprimé et/ou numérique Auteurs : Margaret J. SNOWLING, Auteur ; Charles HULME, Auteur Année de publication : 2012 Article en page(s) : p.593-607 Langues : Anglais (eng) Mots-clés : Reading disorders  language disorders  dyslexia  reading comprehension impairment  intervention Index. décimale : PER Périodiques Résumé : This article reviews our understanding of reading disorders in children and relates it to current proposals for their classification in DSM-5. There are two different, commonly occurring, forms of reading disorder in children which arise from different underlying language difficulties. Dyslexia (as defined in DSM-5), or decoding difficulty, refers to children who have difficulty in mastering the relationships between the spelling patterns of words and their pronunciations. These children typically read aloud inaccurately and slowly, and experience additional problems with spelling. Dyslexia appears to arise principally from a weakness in phonological (speech sound) skills, and there is good evidence that it can be ameliorated by systematic phonic teaching combined with phonological awareness training. The other major form of reading difficulty is reading comprehension impairment. These children read aloud accurately and fluently, but have difficulty understanding what they have read. Reading comprehension impairment appears to arise from weaknesses in a range of oral language skills including poor vocabulary knowledge, weak grammatical skills and difficulties in oral language comprehension. We suggest that the omission of reading comprehension impairment from DSM-5 is a serious one that should be remedied. Both dyslexia and reading comprehension impairment are dimensional in nature, and show strong continuities with other disorders of language. We argue that recognizing the continuities between reading and language disorders has important implications for assessment and treatment, and we note that the high rates of comorbidity between reading disorders and other seemingly disparate disorders (including ADHD and motor disorders) raises important challenges for understanding these disorders.

Comorbidities in preschool children at family risk of dyslexia / Debbie GOOCH in Journal of Child Psychology and Psychiatry, 55-3 (March 2014)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 55-3 (March 2014) . - p.237-246 Titre : Comorbidities in preschool children at family risk of dyslexia Type de document : Texte imprimé et/ou numérique Auteurs : Debbie GOOCH, Auteur ; Charles HULME, Auteur ; Hannah M.

SNOWLING, Auteur Article en page(s) : p.237-246 Langues : Anglais (eng) Mots-clés : Comorbidity  language disorder  dyslexia  motor skills  executive function Index. décimale : PER Périodiques Résumé : Background Comorbidity among developmental disorders such as dyslexia, language impairment, attention deficit/hyperactivity disorder and developmental coordination disorder is common. This study explores comorbid weaknesses in preschool children at family risk of dyslexia with and without language impairment and considers the role that comorbidity plays in determining children's outcomes. Method The preschool attention, executive function and motor skills of 112 children at family risk for dyslexia, 29 of whom also met criteria for language impairment, were assessed at ages 3½ and 4½ years. The performance of these children was compared to the performance of children with language impairment and typically developing controls. Results Weaknesses in attention, executive function and motor skills were associated with language impairment rather than family risk status. Individual differences in language and executive function are strongly related during the preschool period, and preschool motor skills predicted unique variance (4%) in early reading skills over and above children's language ability. Conclusion Comorbidity between developmental disorders can be observed in the preschool years: children with language impairment have significant and persistent weaknesses in motor skills and executive function compared to those without language impairment. Children's early language and motor skills are predictors of children's later reading skills.

Developmental dyslexia: predicting individual risk / Paul A. THOMPSON in Journal of Child Psychology and Psychiatry, 56-9 (September 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-9 (September 2015) . - p.976-987 Titre : Developmental dyslexia: predicting individual risk Type de document : Texte imprimé et/ou numérique Auteurs : Paul A. THOMPSON, Auteur ; Charles HULME, Auteur ; Hannah M. NASH, Auteur ; Debbie GOOCH, Auteur ; Emma HAYIOU-THOMAS, Auteur ; Margaret J. SNOWLING, Auteur Article en page(s) : p.976-987 Langues : Anglais (eng) Mots-clés : Familial (family) risk  dyslexia  reading disability  language skills  executive motor  early identification Index. décimale : PER Périodiques Résumé : Background Causal theories of dyslexia suggest that it is a heritable disorder, which is the outcome of multiple risk factors. However, whether early screening for dyslexia is viable is not yet known. Methods The study followed children at high risk of dyslexia from preschool through the early primary years assessing them from age 3 years and 6 months (T1) at approximately annual intervals on tasks tapping cognitive, language, and executive-motor skills. The children were recruited to three groups: children at family risk of dyslexia, children with concerns regarding speech, and language development at 3;06 years and controls considered to be typically developing. At 8 years, children were classified as ‘dyslexic’ or not. Logistic regression models were used to predict the individual risk of dyslexia and to investigate how risk factors accumulate to predict poor literacy outcomes. Results Family-risk status was a stronger predictor of dyslexia at 8 years than low language in preschool. Additional predictors in the preschool years include letter knowledge, phonological awareness, rapid automatized naming, and executive skills. At the time of school entry, language skills become significant predictors, and motor skills add a small but significant increase to the prediction probability. We present classification accuracy using different probability cutoffs for logistic regression models and ROC curves to highlight the accumulation of risk factors at the individual level. Conclusions Dyslexia is the outcome of multiple risk factors and children with language difficulties at school entry are at high risk. Family history of dyslexia is a predictor of literacy outcome from the preschool years. However, screening does not reach an acceptable clinical level until close to school entry when letter knowledge, phonological awareness, and RAN, rather than family risk, together provide good sensitivity and specificity as a screening battery.

Dyslexia and Developmental Language Disorder: comorbid disorders with distinct effects on reading comprehension / Margaret J. SNOWLING in Journal of Child Psychology and Psychiatry, 61-6 (June 2020)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 61-6 (June 2020) . - p.672-680 Titre : Dyslexia and Developmental Language Disorder: comorbid disorders with distinct effects on reading comprehension Type de document : Texte imprimé et/ou numérique Auteurs : Margaret J. SNOWLING, Auteur ; Marianna E. HAYIOU-THOMAS, Auteur ; Hannah M. NASH, Auteur ; Charles HULME, Auteur Article en page(s) : p.672-680 Langues : Anglais (eng) Mots-clés : Developmental Language Disorder  Reading comprehension  decoding  dyslexia  language Index. décimale : PER Périodiques Résumé : BACKGROUND: Reading comprehension draws on both decoding and linguistic comprehension, and poor reading comprehension can be the consequence of a deficit in either of these skills. METHODS: Using outcome data from the longitudinal Wellcome Language and Reading Project, we identified three groups of children at age 8 years: children with dyslexia (N = 21) who had deficits in decoding but not oral language, children with Developmental Language Disorder (DLD; N = 38) whose decoding skills were in the normal range, and children who met criteria for both dyslexia and DLD (N = 29). RESULTS: All three groups had reading comprehension difficulties at the ages of 8 and 9 years relative to TD controls though those of the children with dyslexia were mild (relative to TD controls, d = 0.51 at age 8, d = 0.60 at age 8); while the most severe problems were found in the comorbid dyslexia + DLD group (d = 1.79 at age 8, d = 2.06 at age 9) those with DLD also had significant difficulties (d = 1.56 at age 8, d = 1.56 at age 9). CONCLUSIONS: These findings confirm that children with dyslexia or DLD are at-risk for reading comprehension difficulties but for different reasons, because of weak decoding in the case of dyslexia or weak oral language skills in the case of DLD. Different forms of intervention are required for these groups of children, targeted to their particular area(s) of weakness.
