Parents and teachers have knowledge of children’s daily motor performance yet may make different judgments about the levels of competence observed at home and school. The current study aimed to examine the discrepancies between parent and teacher reports using the Movement ABC-2 Checklist and the Developmental Coordination Disorder Questionnaire (DCDQ) on children with and without suspected Developmental Coordination Disorder (DCD). The Movement ABC-2 Test was administered to 1276 children aged 5–10 years in China. The Movement ABC-2 Checklist and DCDQ were completed by both parents and teachers of all children. A total of 172 children achieving a score below the 15th percentile on the Movement ABC-2 Test were identified as children with suspected DCD. Both parents and teachers showed suitable agreement in judging children’s motor competence but low sensitivity in identifying children with DCD. Parent scores of children’s motor competence were more closely associated with test performance scores compared to teacher scores. Teachers tended to over-rate children’s motor competence. The motor difficulties identified by parents were associated with low Movement ABC-2 Test scores on Manual Dexterity and Balance components, while motor difficulties identified by teachers were associated with the Balance component only. The results demonstrated discrepancies between parent and teacher reports, suggesting the importance of using a range of measures to identify and describe motor difficulties in children

The ability to finely control our movement is key to the achieving many of the educational milestones and life-skills we develop throughout our lives. Despite the centrality of coordination to our early development, there is a vast gap in our understanding of the underlying biology. Like most complex traits, both genetics and environment influence motor coordination, however, the specific genes, early environmental risk factors and molecular pathways are unknown. Previous studies have shown that about 5% of school-age children experience unexplained difficulties with motor coordination. These children are said to have Developmental Coordination Disorder (DCD). For children with DCD, these motor coordination difficulties significantly impact their everyday life and learning. DCD is associated with poorer academic achievement, reduced quality of life, it can constrain career opportunities and increase the risk of mental health issues in adulthood. Despite the high prevalence of coordination difficulties, many children remain undiagnosed by healthcare professionals. Compounding under-diagnosis in the clinic, research into the etiology of DCD is severely underrepresented in the literature. Here we present the first genome-wide association study (GWAS) to examine the genetic basis of early motor coordination in the context of motor difficulties. Using data from the Avon Longitudinal Study of Parents and Children (ALSPAC) we generate a derived measure of motor coordination from four components of the Movement Assessment Battery for Children (MABC), providing an overall measure of coordination across the full range of ability. We perform the first genome-wide association analysis focused on motor coordination (N=4542). No single nucleotide polymorphisms (SNPs) met the threshold for genome-wide significance however 59 SNPs showed suggestive associations. Three regions contained multiple suggestively associated SNP, within five preliminary candidate genes: IQSEC1, LRCC1, SYN

Purpose of review. Handwriting is a particular difficulty in DCD. Children who struggle to produce legible and sufficiently fast handwriting may under-achieve at school. Using van Galen’s model, this review examines recent research to describe the nature of handwriting difficulties in DCD. The range of assessment tools is highlighted and recommendations for intervention provided. Recent findings. Embedded in the broader skill of writing, handwriting involves more than motor skill. Children with DCD tend to produce less writing than their peers. Their slow rate of production is characterised by frequent pauses. Errors in letter formation negatively impact on legibility and the quality of written composition is also poor. Different types of assessment help to capture the range of difficulties. Summary. Comprehensive assessment helps gain a full understanding of the nature of handwriting difficulties in DCD. International recommendations and guidelines provide a valuable framework for assessment and principles for intervention.

Lifecourse epidemiology suggests that preconception is a valuable opportunity for health promotion with young women. Yet young women are less likely than older women to be research participants, limiting evidence about their needs and risks. Marketing data indicate that young adults are not engaged with one advertising strategy because they transition through three life stages: (1) limited independence and focus on own interests, (2) increased independence and time with peers, (3) establishing a home and family. The aim of this study was to explore whether these marketing lifestage categories could inform the tailoring of strategies to recruit young women.Three focus groups per lifestage category were conducted (49 women aged 16 to 34 years). Lifestage category (1) was represented by further education students, category (2) by women in workplaces, and (3) by mothers. Questions explored participants’ lifestyles, identity, reasons for participation in the current study and beliefs about researchers. Three major themes were identified through framework analysis: Profiling how young women spend their time; Facilitators of participating in research; and Barriers to participating. Students and women in work valued monetary remuneration whereas mothers preferred social opportunities. Participants’ perceived identity influenced whether they felt useful to research. All groups expressed anxiety about participation. Altruism was limited to helping people known to participants. Therefore, the marketing categories did not map exactly to differences in young women’s motivations to participate but have highlighted how one recruitment strategy may not engage all. Mass media communication could, instead, increase familiarity and reduce anxiety about participation.

Knowledge of obstetric and environmental influences on Developmental Coordination Disorder (DCD) helps provide increased understanding of the mechanisms underlying the disorder. However, the literature to date has not adequately examined the obstetric and environmental risk factors for DCD in a population-based sample. The current study was therefore conducted to explore the prenatal, perinatal, neonatal, and family environmental risk factors for DCD. A total of 2185 children aged 3-10 years from a national representative sample in China were included; the Movement Assessment Battery for Children-2 was used to assess motor function, and a questionnaire was completed by parents. DCD was identified in 156 children according to the DSM-5 criteria. Multilevel logistic regression was used, and comparisons were made between the DCD and non-DCD group. The results confirmed that male sex, BMI score, preterm birth, and some prenatal conditions are significant risk factors for DCD. Parents’ education level and one-child status as two significant environmental risk factors for DCD appear largely independent of other risk factors in the Chinese population. This study provides an opportunity to explore the etiology of DCD and suggest potential assessment, monitoring and intervention programs for DCD that could be examined in the future.

It is widely assumed that by identifying spelling errors and suggesting replacement words, spellcheck allows writers to revise spelling errors even if they do not have the necessary spelling knowledge. However, there have been no studies evaluating the efficacy of modern spellcheck tools for students with spelling difficulties, such as dyslexia. In fact, the very limited and dated research into use of spellcheck by writers with dyslexia indicated that, even when using spellcheck to revise spelling errors, this group left many misspellings in their texts. The current study is the first to investigate whether a modern spellcheck program allows college students with dyslexia to produce texts that are as free from misspellings as texts by their peers, and whether this affects the quality of the text in other ways. College students with dyslexia (n=18) and a control group of peers (n=18) wrote two short essays using Microsoft Word, one with spellcheck active and one without spellcheck active. Spelling accuracy and overall quality of the texts were measured. Without spellcheck, students with dyslexia made more misspellings than the control group, however, with spellcheck active students from both groups left almost zero misspelled words in their texts. Text quality was not affected. Results demonstrate that spellcheck helps college students with dyslexia to overcome the limitations that poor spelling knowledge imposes. Importantly, results indicate that spellcheck does not lead to improvements in text beyond spelling accuracy, or lead to poorer quality texts, indicating that it is suitable for use in exam conditions.

Background: Children with Developmental Coordination Disorder (DCD) have motor difficulties which impact their everyday activities. Difficulties with Executive Function (EF) are commonly reported with relationships between EF and motor skills poorly understood. A key component of EF is Inhibition, important for classroom learning and less explored in children with DCD. Study One aimed to investigate the EF skills of children with and without DCD focusing on Inhibition, and Study Two aimed to examine relationships between Inhibition and motor skills. Method: Participants were 25 children with DCD aged six-ten years, and 25 age and gender matched typically developing (TD) children. They completed experimental measures of Inhibition, standardised tests of motor and EF skills, and parents and teachers completed standardised EF questionnaires. Results: Study One. Children with DCD had significantly poorer performance on some experimental and standardised measures of Inhibition and on parent and teacher reports of overall EF skills. Inhibition difficulties were reported by parents but not teachers. Results emphasize the potential for task and environmental demands to influence EF and Inhibition performance. Study Two. Significant relationships between at least one Inhibition measure and all areas of motor skills were found across groups. However, relationships differed across motor domains and Inhibition measures. Many within group correlations were also significant, although there was variation across the DCD and TD groups. This suggests that relationships between EF and motor skills are different for those with and without DCD. Conclusion: Children with DCD have difficulties with Inhibition across a range of measures and some aspects of performance are associated with their level of motor skills. The motor and Inhibition difficulties observed in children with DCD appear to be interdependent. Assessment of children with DCD should include an examination of Inhibition ski

The Test component of the Movement Assessment Battery for Children 2nd Edition (Movement ABC-2) is used worldwide to identify children with Developmental Coordination Disorder (DCD). In China, practitioners have been using this test with the assumption that the published UK norms are valid for Chinese children. However no systematic investigation has previously been undertaken to check this assumption. 2185 children aged 3–10 years old from a national representative sample in China were therefore recruited to the current study. Performance on the Movement ABC-2 was assessed and compared with the UK standardization norms. Gender differences were also examined. The comparisons revealed that Chinese children were generally better in Manual Dexterity and Balance tasks compared to their UK peers; while UK children were better in Aiming & Catching tasks. Further analysis showed an interaction of country and age with mixed results. For both countries, girls were generally better in Manual Dexterity and Balance tasks, and boys were generally better in Aiming & Catching. Possible explanations for the country differences are discussed. The results suggest that local norms for the Movement ABC-2 Test are needed in China.

Aim. These international clinical practice recommendations (CPR) for developmental coordination disorder (DCD), initiated by the European Academy of Childhood Disability (EACD), aim to address key questions on the definition, diagnosis, assessment, intervention, and psychosocial aspects of DCD relevant for clinical practice. Method. Key questions in five areas were considered through literature reviews and formal expert consensus. For recommendations based on evidence, literature searches on ‘mechanisms’, ‘assessment’, and ‘intervention’ were updated since the last recommendations in 2012. New searches were conducted for ‘psychosocial issues’ and ‘adolescents/adults’. Evidence was rated according to the Oxford Centre for Evidence-Based Medicine (level of evidence [LOE] 1–4) and transferred into recommendations. For recommendations based on formal consensus, two meetings of an international, multidisciplinary expert panel were conducted with a further five Delphi rounds to develop good clinical practice (GCP) recommendations. Results. Thirty-five recommendations were made. Eight were based on the evidence from literature reviews (three on ‘assessment’, five on ‘intervention’). Twenty-two were updated from the 2012 recommendations. New recommendations relate to diagnosis and assessment (two GCPs) and psychosocial issues (three GCPs). Additionally, one new recommendation (LOE) reflects active video games as adjuncts to more traditional activity-oriented and participation-oriented interventions, and two new recommendations (one GCP, one LOE) were made for adolescents and adults with DCD. Interpretation. The CPR–DCD is a comprehensive overview of DCD and current understanding based on research evidence and expert consensus. It reflects the state of the art for clinicians and scientists of varied disciplines. The international CPR–DCD may serve as a basis for national guidelines.

Background. The standardized test within the Movement Assessment Battery for Children-2nd edition (MABC-2) is used worldwide to assess motor problems in children. Ideally, any country using a test developed in another country should produce national norms to ensure that it functions effectively in the new context. Aim. The first objective of this study was to explore the differences in motor performance between Italian and British children. The second was to examine the structural validity of the test for the Italian sample. Method. A total of 718 Italian (IT) and 765 British (UK) children, aged 3–10 years, were individually tested on the age-appropriate items of the MABC-2 Test. Results. Developmental trends emerged on every task and differences between IT and UK children were obtained on 11 of 27 task comparisons. Interactions between age and country indicated that differences were not consistently in favor of one culture. Confirmatory factor analysis generally supported the proposed structure of the MABC-2 Test. Conclusion. Although the differences between the IT and the UK children were relatively few, those that did emerge emphasize the need for population specific norms and suggest that cultural diversity in motor experiences should be considered when evaluating motor abilities in children.

Movement, which draws on motor skills and executive functions for managing them, plays an important role in literacy learning (e.g., movement of mouth during oral reading and movement of hand and fingers during writing); but relatively little research has focused on movement skills in students with specific learning disabilities (SLDs) as the current study did. Parents completed normed Movement Assessment Battery for Children Checklist - 2nd edition (ABC-2), ratings and their children in grades 4 to 9 (M=11 years, 11 months; 94 boys, 61 girls) completed diagnostic assessment used to assign them to diagnostic groups: control typical language learning (N=42), dysgraphia (impaired handwriting) (N=29), dyslexia (impaired word decoding/reading and spelling) (N=65), or oral and written language learning disability (OWL LD) (impaired syntax in oral and written language) (N=19). The research aims were to (a) correlate the Movement ABC-2 parent ratings for Scale A Static/ Predictable Environment (15 items) and Scale B Dynamic/ Unpredictable Environment (15 items) with reading and writing achievement in total sample varying within and across different skills; and (b) compare each SLD group with the control group on Movement ABC-2 parent ratings for Scale A, Scale B, and Scale C Movement-Related (Non-Motor Executive Functions, or Self-Efficacy, or Affect) (13 items). At least one Movement ABC-2 parent rating was correlated with each assessed literacy achievement skill. Each of three SLD groups differed from the control group on two Scale A (static/ predictable environment) (fastens buttons and forms letters with pencil or pen) and on three Scale C (non-motor, movement-related) (distractibility, overactive, and underestimates own ability) items; but only OWL LD differed from control on Scale B (dynamic/unpredictable) items. Applications of findings to assessment and instruction for students ascertained for and diagnosed with persisting SLDs in literacy learning, and future rese
