Phonics training for English-speaking poor readers (Review)

Background The reading skills of 16% of children fall below the mean range for their age, and 5% of children have significant and severe reading problems. Phonics training is one of the most common reading treatments used with poor readers, particularly children. Objectives To measure the effect of phonics training and explore the impact of various factors, such as training duration and training group size, that might moderate the effect of phonics training on literacy‐related skills in English‐speaking poor readers. Search methods We searched CENTRAL, MEDLINE, Embase, 12 other databases, and three trials registers up to May 2018. We also searched reference lists of included studies and contacted experts in the field to identify additional studies. Selection criteria We included studies that used randomisation, quasi‐randomisation, or minimisation to allocate participants to a phonics intervention group (phonics training only or phonics training plus one other literacy‐related skill) or a control group (no training or non‐literacy training). Participants were English‐speaking poor readers with word reading one standard deviation below the appropriate level for their age (children, adolescents, and adults) or one grade or year below the appropriate level (children only), for no known reason. Participants had no known comorbid developmental disorder, or physical, neurological, or emotional problem. Data collection and analysis We used standard methodological procedures expected by Cochrane. Main results We included 14 studies with 923 participants in this review. Studies took place in Australia, Canada, the UK, and the USA. Six of the 14 included studies were funded by government agencies and one was funded by a university grant. The rest were funded by charitable foundations or trusts. Each study compared phonics training alone, or in conjunction with one other reading‐related skill, to either no training (i.e. treatment as usual) or alterative training (e.g. maths). Participants were English‐speaking children or adolescents, of low and middle socioeconomic status, whose reading was one year, one grade, or one standard deviation below the level expected for their age or grade for no known reason. Phonics training varied between studies in intensity (up to four hours per week), duration (up to seven months), training group size (individual and small groups), and delivery (human and computer). We measured the effect of phonics training on seven primary outcomes (mixed/regular word reading accuracy, non‐word reading accuracy, irregular word reading accuracy, mixed/regular word reading fluency, non‐word reading fluency, reading comprehension, and spelling). We judged all studies to be at low risk of bias for most risk criteria, and used the GRADE approach to assess the quality of the evidence. There was low‐quality evidence that phonics training may have improved poor readers' accuracy for reading real and novel words that follow the letter‐sound rules (standardised mean difference (SMD) 0.51, 95% confidence interval (CI) 0.13 to 0.90; 11 studies, 701 participants), and their accuracy for reading words that did not follow these rules (SMD 0.67, 95% CI 0.26 to 1.07; 10 studies, 682 participants). There was moderate‐quality evidence that phonics training probably improved English‐speaking poor readers' fluency for reading words that followed the letter‐sounds rules (SMD 0.45, 95% CI 0.19 to 0.72; 4 studies, 224 participants), and non‐word reading fluency (SMD 0.39, 95% CI 0.10 to 0.68; 3 studies, 188 participants), as well as their accuracy for reading words that did not follow these rules (SMD 0.84, 95% CI 0.30 to 1.39; 4 studies, 294 participants). In addition, there was low‐quality evidence that phonics training may have improved poor readers' spelling (SMD 0.47, 95% CI –0.07 to 1.01; 3 studies, 158 participants), but only slightly improve their reading comprehension (SMD 0.28, 95% CI –0.07 to 0.62; 5 studies, 343 participants). Authors' conclusions Phonics training appears to be effective for improving literacy‐related skills, particularly reading fluency of words and non‐words, and accuracy of reading irregular words. More studies are needed to improve the precision of outcomes, including word and non‐word reading accuracy, reading comprehension, spelling, letter‐sound knowledge, and phonological output. More data are also needed to determine if phonics training in English‐speaking poor readers is moderated by factors such as training type, intensity, duration, group size, or administrator

Algorithms for the diagnosis and treatment of restless legs syndrome in primary care

<p>Abstract</p> <p>Background</p> <p>Restless legs syndrome (RLS) is a neurological disorder with a lifetime prevalence of 3-10%. in European studies. However, the diagnosis of RLS in primary care remains low and mistreatment is common.</p> <p>Methods</p> <p>The current article reports on the considerations of RLS diagnosis and management that were made during a European Restless Legs Syndrome Study Group (EURLSSG)-sponsored task force consisting of experts and primary care practioners. The task force sought to develop a better understanding of barriers to diagnosis in primary care practice and overcome these barriers with diagnostic and treatment algorithms.</p> <p>Results</p> <p>The barriers to diagnosis identified by the task force include the presentation of symptoms, the language used to describe them, the actual term "restless legs syndrome" and difficulties in the differential diagnosis of RLS.</p> <p>Conclusion</p> <p>The EURLSSG task force reached a consensus and agreed on the diagnostic and treatment algorithms published here.</p

Pirates at parties : letter position processing in developing readers

There has been much recent interest in letter position coding in adults, but little is known about the development of this process in children learning to read. Here, the letter position coding abilities of 127 children in Grades 2, 3, and 4 (aged 7-10. years) were examined by comparing their performance in reading aloud "migratable" words (e.g., bread, three, diary) with that in reading aloud words without potential for migration (e.g., heard, boot, bitter). Across all three grade levels, children made many more errors on migratable words than on non-migratable words, and the proportion of migration errors did not decrease with increasing grade level. Within each grade, a tendency to make a high proportion of migration errors was not associated with deficits in other reading subprocesses or with general lexical guessing; indeed, it was associated with strong lexical reading skills. We conclude that letter position coding is generally fragile in developing readers and that this interacts with lexical knowledge to produce migration errors in reading.17 page(s

Subtypes of developmental reading disorders : recent developments and directions for treatment

This paper presents an overview of several subtypes of developmental reading disorders including phonological dyslexia, surface dyslexia, hyperlexia, poor comprehenders, and the less-recognised subtypes of letter position dyslexia and attentional dyslexia. Although clinicians may be familiar with the symptoms of phonological and surface dyslexia, the symptoms of the other reading disorders noted may be less familiar and therefore methods of assessment and directions for treatment may be unclear. Each subtype is described and accounted for in the context of the dual route theory of reading. Current research on remediation strategies is also surveyed, providing a basis for developing treatment programs for both pure and complex developmental reading disorders.5 page(s

Assessing spelling skills and strategies : a critique of available resources

In this paper, we discuss a variety of spelling tests that are used to assess developmental spelling difficulties. We differentiate between tests that are valuable tools to monitor spelling development and spelling tests that should be used to further assess children who are not making sufficient progress in the mainstream classroom. We recommend the use of several tests in order to achieve these assessment goals. This paper is a practical guide for clinicians and teachers concerned with the assessment (and treatment) of poor spellers.38 page(s

Developmental disorders : what can be learned from cognitive neuropsychology?

The discipline of cognitive neuropsychology has been important for informing theories of cognition and describing the nature of acquired cognitive disorders, but its applicability in a developmental context has been questioned. Here, we revisit this issue, asking whether the cognitive neuropsychological approach can be helpful for exploring the nature and causes of developmental disorders and, if so, how. We outline the key features of the cognitive neuropsychological approach, and then consider how some of the major challenges to this approach from a developmental perspective might be met. In doing so, we distinguish between challenges to the methods of cognitive neuropsychology and those facing its deeper conceptual underpinnings. We conclude that the detailed investigation of patterns of both associations and dissociations, and across both developmental and acquired cases, can assist in describing the cognitive deficits within developmental disorders and in delineating possible causal pathways to their acquisition.9 page(s

The Locus of impairment in English developmental letter position dyslexia

Many children with reading difficulties display phonological deficits and struggle to acquire non-lexical reading skills. However, not all children with reading difficulties have these problems, such as children with selective letter position dyslexia (LPD), who make excessive migration errors (such as reading slime as "smile"). Previous research has explored three possible loci for the deficit - the phonological output buffer, the orthographic input lexicon, and the orthographic-visual analysis stage of reading. While there is compelling evidence against a phonological output buffer and orthographic input lexicon deficit account of English LPD, the evidence in support of an orthographic-visual analysis deficit is currently limited. In this multiple single-case study with three English-speaking children with developmental LPD, we aimed to both replicate and extend previous findings regarding the locus of impairment in English LPD. First, we ruled out a phonological output buffer and an orthographic input lexicon deficit by administering tasks that directly assess phonological processing and lexical guessing. We then went on to directly assess whether or not children with LPD have an orthographic-visual analysis deficit by modifying two tasks that have previously been used to localize processing at this level: a same-different decision task and a non-word reading task. The results from these tasks indicate that LPD is most likely caused by a deficit specific to the coding of letter positions at the orthographic-visual analysis stage of reading. These findings provide further evidence for the heterogeneity of dyslexia and its underlying causes.14 page(s

Low self-concept in poor readers: prevalence, heterogeneity, and risk

There is evidence that poor readers are at increased risk for various types of low self-concept—particularly academic self-concept. However, this evidence ignores the heterogeneous nature of poor readers, and hence the likelihood that not all poor readers have low self-concept. The aim of this study was to better understand which types of poor readers have low self-concept. We tested 77 children with poor reading for their age for four types of self-concept, four types of reading, three types of spoken language, and two types of attention. We found that poor readers with poor attention had low academic self-concept, while poor readers with poor spoken language had low general self-concept in addition to low academic self-concept. In contrast, poor readers with typical spoken language and attention did not have low self-concept of any type. We also discovered that academic self-concept was reliably associated with reading and receptive spoken vocabulary, and that general self-concept was reliably associated with spoken vocabulary. These outcomes suggest that poor readers with multiple impairments in reading, language, and attention are at higher risk for low academic and general self-concept, and hence need to be assessed for self-concept in clinical practice. Our results also highlight the need for further investigation into the heterogeneous nature of self-concept in poor readers
