RESUMEN
Higher education providers are seeing a shift from externally funded support for students with specific learning difficulties (SpLD), to a need to develop more inclusive practices generally. However, the precise needs of students with different SpLD diagnoses is unknown. A total of 367 students in England and Wales (163 students with dyslexia, 50 students with developmental coordination disorder [DCD/"dyspraxia"], 62 students with dyslexia and DCD, and 92 non-SpLD students) completed an online questionnaire to determine: (a) how confident they are with their study-related capabilities, (b) the types of support they access, and (c) their views on current inclusive practices. Students with dyslexia and students with dyslexia/DCD reported lower confidence in their grades and studying than non-SpLD students, and accessed more technology-related support than students with DCD only. Examination accommodations supporting writing were common for all SpLD students. Inclusive practices were perceived positively, although different priorities were seen across groups. The findings demonstrate the complexities inherent in providing effective support for all students at university, with the varied profiles across and within SpLD groups suggesting that an individualized approach is necessary. Practical implications are discussed.

OBJECTIVES: Clear and efficient communication between nursing staff and medical providers is an essential component of healthcare delivery. At McLean Hospital, there is an inconsistency in utilization of alphanumeric paging, with many individuals communicating primarily via numeric-only pages that can cause difficulty in triaging importance of pages and lead to disruptions in care. This quality improvement project sought to improve communication between nursing staff and residents by decreasing the number of difficult to triage pages sent to the psychiatrist-on-call at a stand-alone academic psychiatric hospital. METHODS: Pages were analyzed during two discrete month-long periods before and after the implementation of a standardized paging protocol, which included an updated online template asking the individual sending the page to include specific information (urgency of page, identifying information of patient, contact information, and name of sender) and dissemination of information on its use. RESULTS: The implementation of this protocol resulted in a statistically significant decrease in the percentage of pages that were difficult to triage (22.1 to 15.0%; p < 0.05). Examining specific units in the hospital revealed significant variation of change, with as much as 40% reduction to as large as an 11% increase in difficult to triage pages. CONCLUSIONS: The decrease in the percentage of difficult to triage pages suggests that a standard paging protocol can improve delivery of patient care by minimizing interruptions with low-priority pages and may improve quality of communication between nursing staff and physicians on-call, ultimately improving quality of care provided and bettering the resident learning environment.

Children with Developmental Coordination Disorder (DCD) fail to acquire adequate motor skill, yet surprisingly little is known about the oculomotor system in DCD. Successful completion of motor tasks is supported by accurate visual feedback. The purpose of this study was to determine whether any oculomotor differences can distinguish between children with and without a motor impairment. Using eye tracking technology, visual fixation, smooth pursuit, and pro- and anti-saccade performance were assessed in 77 children that formed three groups: children with DCD (aged 7-10), chronologically age (CA) matched peers, and a motor-match (MM) group (aged 4-7). Pursuit gain and response preparation in the pro- and anti-saccade tasks were comparable across groups. Compared to age controls, children with DCD had deficits in maintaining engagement in the fixation and pursuit tasks, and made more anti-saccade errors. The two typically developing groups performed similarly, except on the fast speed smooth pursuit and antisaccade tasks, where the CA group outperformed the younger MM group. The findings suggest that children with DCD have problems with saccadic inhibition and maintaining attention on a visual target. Developmental patterns were evident in the typically developing groups, suggesting that the pursuit system and cognitive control develop with age. This study adds to the literature by being the first to systematically identify specific oculomotor differences between children with and without a motor impairment. Further examination of oculomotor control may help to identify underlying processes contributing to DCD. A video abstract of this article can be viewed at: https://youtu.be/NinXa2KlB4M.

AIM: Executive function impairments have been identified in children with poor motor skills, with and without a diagnosis of developmental coordination disorder (DCD). However, most studies are cross-sectional. This study investigates the development of executive function in children with poor motor skills over 2 years. METHOD: Children aged 7 to 11 years (n=51) were assessed twice, 2 years apart, on verbal and nonverbal measures of executive functions: executive-loaded working memory (ELWM); fluency; response inhibition; planning; and cognitive flexibility. Typically developing children (n=17) were compared with those with a clinical diagnosis of DCD (n=17) and those with identified motor difficulties (n=17) but no formal diagnosis of DCD. RESULTS: Developmental gains in executive function were similar between groups, although a gap between children with poor motor skills and typically developing children on nonverbal executive functions persisted. Specifically, children with DCD performed significantly more poorly than typically developing children on all nonverbal executive function tasks and verbal fluency tasks at both time points; and children with motor difficulties but no diagnosis of DCD showed persistent executive function problems in nonverbal tasks of ELWM and fluency. INTERPRETATION: Children with DCD and motor difficulties demonstrated executive function difficulties over 2 years, which may affect activities of daily living and academic achievement, in addition to their motor deficit. WHAT THIS PAPER ADDS: Executive function difficulties in children with poor motor skills persist throughout middle childhood. Children with motor difficulties, without a developmental coordination disorder (DCD) diagnosis, demonstrate less pervasive executive function difficulties than those with DCD. Executive function problems in the groups with motor difficulties and DCD affect mostly nonverbal domains. All groups showed similar developmental gains in executive function.

Previous research has suggested that infant motor skills may be affected by older siblings but has not considered whether this is due to specific characteristics of the older sibling or of the quality of the sibling relationship. The current study used a longitudinal diary method to record infant motor milestones from 23 infants with older siblings along with parent reports and standardized assessments of motor skills. Parent reports of the older siblings' motor skills and the sibling relationship were also collected until the infants were 18months old. The motor skills, age, and sex of the older siblings were not significantly related to any measure of infant motor development. A significant correlation was revealed between perceived agonism between siblings and infant fine motor skills at 18months, suggesting the importance of considering reciprocal effects of motor development on sibling relationships. Overall, the suggestion that older siblings may provide a good model of motor skills for infants is not supported by the current data. In the future, it will be important to assess the dynamic interactions between different factors in predicting infant motor development, allowing early identification of motor difficulties, which could affect other areas of cognitive development and health.

BACKGROUND: Developmental Coordination Disorder (DCD) affects the learning and performance of everyday motor skills. It commonly co-occurs with other developmental disorders and a range of associated psycho-social impairments. Recent evidence-based guidelines on diagnosis, assessment, and intervention provide valuable information for practitioners. However these are directed primarily at German-speaking countries and focus on work with children. AIM: The aim of this project was to consider the application of these guidelines in the UK and to extend them for use with adults with DCD. METHODS: Individuals with DCD, parents, and professionals from a wide range of disciplines were invited to two workshops to discuss and debate the guidelines, to adapt them for the UK and produce dissemination materials. RESULTS: A working definition of DCD was agreed, minor revisions were made to the guidelines to reflect the UK context, an extension for adults was compiled and a series of leaflets was produced to disseminate this information to health and education professionals, parents, and employers. CONCLUSIONS: This work will raise awareness of the condition across different professional groups. It provides information to help those working with children and adults with DCD in the UK to assist in the process of diagnosis, assessment, and intervention.

BACKGROUND: Motor development allows infants to gain knowledge of the world but its vital role in social development is often ignored. METHOD: A systematic search for papers investigating the relationship between motor and social skills was conducted, including research in typical development and in Developmental Coordination Disorder, Autism Spectrum Disorders and Specific Language Impairment. RESULTS: The search identified 43 studies, many of which highlighted a significant relationship between motor skills and the development of social cognition, language and social interactions. CONCLUSIONS: This complex relationship requires more attention from researchers and practitioners, allowing the development of more tailored intervention techniques for those at risk of motor, social and language difficulties.
RESUMEN
Adults with Developmental Coordination Disorder (DCD), sometimes referred to as dyspraxia, experience difficulties in motor development and coordination, which impacts on all aspects of their daily lives. Surprisingly little is known about the mechanisms underlying the difficulties they experience in the motor domain. In childhood DCD, aspects of oculomotor control have been shown to be altered. The purpose of this study was to determine whether oculomotor differences are present in adults with and without probable DCD. Visual fixation stability, smooth pursuit, and pro-and anti-saccade performance were assessed in 21 adults (mean age 29 years) with probable DCD/dyspraxia (pDCD) and 21 typically-developing (TD) adults (mean age 21 years). Eye tracking technology revealed that oculomotor response preparation in the pro- and anti-saccade tasks was comparable across groups, as was pursuit gain in the slower of the two smooth pursuit tasks. However, adults with pDCD made significantly more saccades away from the fixation target than those without DCD and significantly more anti-saccade errors. Further, compared to TD adults, adults with pDCD demonstrated difficulties in maintaining engagement and had lower pursuit gain in the faster pursuit task. This suggests that adults with pDCD have problems with saccadic inhibition and maintaining attention on a visual target. Since this pattern of results has also been reported in children with DCD, oculomotor difficulties may be persistent for those with DCD across the lifespan. An awareness of the impact of atypical oculomotor control in activities of daily living across the lifespan would support clearer understanding of the causes and impacts of these difficulties for those with DCD.
RESUMEN
BACKGROUND: Developmental coordination disorder (DCD) affects up to 6% of the population and is diagnosed on the basis of poor motor coordination. While we know rather little about its lifetime consequences, clear and significant difficulties remain through the lifespan for the majority. Reduced physical activity and, outside of the motor domain, significant mental health issues exist for many with DCD. AIMS: This study provides the first investigation of the presence of mood disorders in adults with DCD. METHOD: Symptoms of anxiety and depression were assessed using the Beck Depression and Spielberger Anxiety Inventories in 36 adults previously diagnosed with DCD vs. 49 age- and gender-matched typical controls. Amount and type of physical activity undertaken each week were also reported. RESULTS: After controlling for their reduced level of weekly physical activity, the group with DCD reported significantly more symptoms of depression, state and trait anxiety than their peers. CONCLUSIONS: This finding has important implications for consideration of intervention in DCD, as well as for investigation of the risk and protective factors at play in long-term outcome. Finally, the findings highlight the need for awareness of motor difficulties in those presenting with high levels of anxiety and depression, and vice versa.

Sixteen adults (diagnosed or self-identified as autistic) participated in one of two iterations of a ten-week autistic-led programme, aimed at helping autistic adults learn more about autism within a peer group context. Motivations for taking part in the programme included a desire for: (1) exploration of autism; (2) empowerment; and (3) the development of practical strategies and coping mechanisms. Interviews were conducted upon completion of the programme and again 6 months later. Using thematic analysis, three themes were identified: (1) appreciation of the autistic-led nature of the programme; (2) unity in diversity; and (3) developing a positive, practical outlook on autism. These promising initial results highlight the value of autistic-led peer support for those recently diagnosed/identified as autistic.

BACKGROUND: Developmental Coordination Disorder (DCD), also called Dyspraxia, is a common Neurodevelopmental Disorder (NDD) that affects motor coordination with a marked impact on both academic and day-to-day living activities. It is increasingly clear that NDDs such as Attention-Deficit/Hyperactivity Disorder and Autism Spectrum Disorder may present differently in males and females, resulting in underdiagnoses of women and girls. AIMS: To consider age and gender differences in the presentation of at-risk and probable DCD. METHODS AND PROCEDURES: A sample of 1,476 adults aged 16-60 years were surveyed online using the Adult DCD Checklist. OUTCOMES AND RESULTS: Women with at-risk (n = 1 8 6, 1 6. 6 %) or probable DCD (n = 6 4 3, 5 6. 6 %) reported significantly greater gross motor and non-motor difficulties and significantly greater impact on activities and participation, whereas men with at-risk (n = 58,16.3 %) or probable (n = 177,49.9 %), DCD reported significantly greater fine motor difficulties. Emerging adults (aged 16-25 years) with at-risk (n = 65,14.3 %) or probable (293,64.3 %) DCD reported significantly greater non-motor difficulty than adults (aged 26-60+ years) with at-risk (n = 179,17.5 %) or probable (n = 518, 50.8 %) DCD. CONCLUSIONS AND IMPLICATIONS: Both age and gender differences were found in the presentation of at-risk and probable DCD in adults. This may have implications for the development of future DCD assessment tools and for the training of front-line staff who may encounter individuals with DCD throughout their lives, including teachers, doctors and employers' Human Resources and Occupational Health staff.

BACKGROUND: The prevalence of motor impairment is high in ADHD, but we do not know if this stems from infancy. AIMS: 1) to compare the acquisition of motor milestones across three groups: Typically Developing (TD), Attention Deficit Hyperactivity Disorder (ADHD) and Developmental Coordination Disorder (DCD); 2) to determine the relationship between current motor ability and ADHD characteristics in children with ADHD. METHODS AND PROCEDURES: The parents of children aged 8-16 years (ADHD, N = 100; DCD, N = 66; TD, N = 40) completed three online questionnaires: Motor milestone questionnaire; Developmental Coordination Disorder Questionnaire (DCDQ'07) (concurrent motor ability); Conners 3 Parent Rating Scale Long Form (ADHD characteristics). OUTCOME AND RESULTS: When considered as a group, the ADHD group achieved motor milestones within a typical timeframe, despite concurrent motor impairments. Motor ability was not associated with ADHD characteristics. Latent Profile Analysis demonstrated that 56 % of the ADHD group and 48 % of the DCD group shared the same profile of motor milestone achievement, concurrent motor ability and ADHD characteristics. OUTCOMES AND CONCLUSIONS: Unlike children with DCD, the motor impairment often observed in ADHD is not evident from infancy. It is also not part of the ADHD phenotype. Individual differences analysis demonstrated the broad heterogeneity of the ADHD phenotype.

Lateralisation of hand preference and manual dexterity are known to develop over childhood, while in adulthood strength of hand preference has been shown to interact with extrinsic task demands. Some evidence exists to suggest that strength of hand preference and motor skill may be related. In the current study a handedness inventory, midline crossing (QHP) and peg-moving tasks were used to investigate: (1) the development of hand preference between 4 and 11 years; (2) whether extrinsic task demands affect strength of hand preference, and (3) whether strength of hand preference was associated with manual dexterity. Younger children (4-5 years) showed weak hand preference in comparison to older children (8-11 years), and extrinsic task demands influenced willingness to cross the body's midline with the preferred hand. Age and peg-moving speed were associated with midline crossing in certain task conditions. Overall, results suggest a coupling between manual dexterity and brain maturation in typical development.

In typical infants, the achievement of independent locomotion has a positive impact on the development of both small-scale and large-scale spatial cognition. Here we investigated whether this association between the motor and spatial domain: (1) persists into childhood and (2) is detrimental to the development of spatial cognition in individuals with motor deficits, namely, individuals with attention deficit hyperactivity disorder (ADHD) and individuals with Williams syndrome (WS). Despite evidence of a co-occurring motor impairment in many individuals with ADHD, little is known about the developmental consequences of this impairment. Individuals with WS demonstrate impaired motor and spatial competence, yet the relationship between these two impairments is unknown. Typically developing (TD) children (N = 71), individuals with ADHD (N = 51), and individuals with WS (N = 20) completed a battery of motor tasks, a measure of independent exploration, and a virtual reality spatial navigation task. Retrospective motor milestone data were collected for the ADHD and WS groups. Results demonstrated a relationship between fine motor ability and spatial navigation in the TD group, which could reflect the developmental impact of the ability to manually manipulate objects, on spatial knowledge. In contrast, no relationships between the motor and spatial domains were observed for the ADHD or WS groups. Indeed, while there was evidence of motor impairment in both groups, only the WS group demonstrated an impairment in large-scale spatial navigation. The motor-spatial relationship in the TD, but not the ADHD and WS groups, suggests that aspects of spatial cognition can develop via a developmental pathway which bypasses input from the motor domain.
RESUMEN
Developmental coordination disorder (DCD) is a neurodevelopmental condition affecting motor coordination in children and adults. Here, EEG signals elicited by visual and tactile stimuli were recorded while adult participants with and without probable DCD (pDCD) performed a motor task. The task cued reaching movements towards a location in visible peripersonal space as well as an area of unseen personal space. Event-related potentials elicited by visual and tactile stimuli revealed that visual processing was strongly affected by movement preparation in the pDCD group, even more than in controls. However, in contrast to the controls, tactile processing in unseen space was unaffected by movement preparation in the pDCD group. The selective use of sensory information from vision and proprioception is fundamental for the adaptive control of movements, and these findings suggest that this is impaired in DCD. Additionally, the pDCD group showed attenuated motor rhythms (beta: 13-30â¯Hz) over sensorimotor regions following cues to prepare movements towards unseen personal space. The results reveal that individuals with pDCD exhibit differences in the neural mechanisms of spatial selection and action preparation compared to controls, which may underpin the sustained difficulties they experience. These findings provide new insights into the neural mechanisms potentially disrupted in this highly prevalent disorder.
RESUMEN
Difficulties with social interaction have been reported in both children with an autism spectrum disorder (ASD) and children with developmental coordination disorder (DCD), although these disorders have very different diagnostic characteristics. To date, assessment of social skills in a DCD population has been limited to paper-based assessment or parent report. The present study employed eye tracking methodology to examine how children attend to socially-relevant stimuli, comparing 28 children with DCD, 28 children with ASD and 26 typically-developing (TD) age-matched controls (aged 7-10). Eye movements were recorded while children viewed 30 images, half of which were classed as 'Individual' (one person in the scene, direct gaze) and the other half were 'Social' (more naturalistic scenes showing an interaction). Children with ASD spent significantly less time looking at the face/eye regions in the images than TD children, but children with DCD performed between the ASD and TD groups in this respect. Children with DCD demonstrated a reduced tendency to follow gaze, in comparison to the ASD group. Our findings confirm that social atypicalities are present in both ASD and to a lesser extent DCD, but follow a different pattern. Future research would benefit from considering the developmental nature of the observed findings and their implications for support.

There has been considerable debate and interest in the factor structure of executive functioning (EF). For children and young people, there is evidence of a progression from a single factor to a more differentiated structure, although the precise nature of these factors differs between investigations. The purpose of the current study was to look at this issue again with another sample, and try to understand possible reasons for previous differences between investigations. In addition, we examined the relationship between less central EF tasks, such as fluency and planning, to the more common tasks of updating/executive working memory (EWM), inhibition, and switching/shifting. A final aim was to carry out analyses which are relevant to the debate about whether EF is influenced by language ability, or language ability is influenced by EF. We reasoned that if language ability affects EF, a factor analysis of verbal and non-verbal EF tasks might result in the identification of a factor which predominantly contains verbal tasks and a factor that predominately contains non-verbal tasks. Our investigation involved 128 typically developing participants (mean age 10:4) who were given EF assessments that included verbal and non-verbal versions of each task: EWM; switching; inhibition; fluency; and planning. Exploratory factor analyses on EWM, switching, and inhibition produced a structure consisting of inhibition in one factor and the remaining tasks in another. It was decided to exclude verbal planning from the next analyses of all the ten tasks because of statistical considerations. Analysis of the remaining nine EF tasks produced two factors, one factor containing the two inhibition tasks, and another factor that contained all the other tasks (switching, EWM, fluency, and non-verbal planning). There was little evidence that the verbal or non-verbal elements in these tasks affected the factor structure. Both these issues are considered in the discussion, where there is a general evaluation of findings about the factor structure of EF.
RESUMEN
Accessing an autism diagnosis is a key milestone, both for an individual and their family. Using a qualitative methodology, the current study examined the views and experiences of ten autistic adults, ten parents of children on the autism spectrum, and ten professionals involved in autism diagnosis, all based in the United Kingdom (UK). Interviewing these 30 respondents about the diagnostic process and subsequent support options, the goal was to identify aspects of the diagnostic process that are working well, and areas in which improvements are needed. Using thematic analysis, three key themes were identified: the process of understanding and accepting autism; multiple barriers to satisfaction with the diagnostic process; and inadequate post-diagnostic support provision.

BACKGROUND: Although characterised by motor impairments, children with Developmental Coordination Disorder (DCD) also show high rates of psychopathology (anxiety, depression, low self-esteem). Such findings have led to calls for the screening of mental health problems in this group. AIMS: To investigate patterns and profiles of emotional and behavioural problems in children with and without DCD, using the Strengths and Difficulties Questionnaire (SDQ). METHODS AND PROCEDURES: Teachers and parents completed SDQs for 30 children with DCD (7-10 years). Teacher ratings on the SDQ were also obtained from two typically-developing (TD) groups: 35 children matched for chronological age, and 29 younger children (4-7 years) matched by motor ability. OUTCOMES AND RESULTS: Group and individual analyses compared parent and teacher SDQ scores for children with DCD. Teacher reports showed that children with DCD displayed higher rates of emotional and behavioural problems (overall, and on each subscale of the SDQ) relative to their TD peers. No differences were observed between the two TD groups. Inspection of individual data points highlighted variability in the SDQ scores of the DCD group (across both teacher and parent ratings), with suggestions of elevated hyperactivity but comparably lower levels of conduct problems across this sample. Modest agreement was found between teacher and parent ratings of children with DCD on the SDQ. CONCLUSIONS AND IMPLICATIONS: There is a need to monitor levels of emotional and behavioural problems in children with DCD, from multiple informants.

When localizing touches to the hands, typically developing children and adults show a "crossed hands effect" whereby identifying which hand received a tactile stimulus is less accurate when the hands are crossed than uncrossed. This demonstrates the use of an external frame of reference for locating touches to one's own body. Given that studies indicate that developmental vision plays a role in the emergence of external representations of touch, and reliance on vision for representing the body during action is atypical in developmental coordination disorder (DCD), we investigated external spatial representations of touch in children with DCD using the "crossed hands effect". Nineteen children with DCD aged 7-11years completed a tactile localization task in which posture (uncrossed, crossed) and view (hands seen, unseen) were varied systematically. Their performance was compared to that of 35 typically developing controls (19 of a similar age and cognitive ability, and 16 of a younger age but similar fine motor ability). Like controls, the DCD group exhibited a crossed hands effect, whilst their overall tactile localization performance was weaker than their peers of similar age and cognitive ability, but in line with younger controls of similar motor ability. For children with movement difficulties, these findings indicate tactile localization impairments in relation to age expectations, but apparently typical use of an external reference frame for localizing touch.
