Empathy, social relationship and co-occurrence in young adults with DCD

Differences in Praxis Errors in Autism Spectrum Disorder Compared to Developmental Coordination Disorder

This study aimed to better understand how autism spectrum disorder (ASD) and developmental coordination disorder (DCD) differ in types of praxis errors made on the Florida Apraxia Battery Modified (FAB-M) and the potential relationships between praxis errors and social deficits in ASD. The ASD group made significantly more timing sequencing errors in imitation of meaningful gestures, as well as more body-part-for-tool errors during gesture-to-command compared to the other two groups. In the ASD group, increased temporal errors in meaningful imitation were significantly correlated with poorer affect recognition and less repetitive behaviors. Thus, in ASD, aspects of imitation ability are related to socioemotional skills and repetitive behaviors.

Journeying with developmental coordination disorder: The family experience

Background

Developmental coordination disorder (DCD) is a neurodevelopmental disorder impacting 5% - 6% of children and continues into adulthood for 50% - 70% of cases. Despite the multidomain and lifelong influence of this disorder, little consideration has been given to the experiences of the family. Post-diagnostic support has been recommended however, the specific areas requiring support remain vague.

Objectives

This study described the familial experiences of living with a member diagnosed with DCD.

Method

A qualitative descriptive study using a phenomenological approach allowed insight into the lived experiences of families journeying with DCD. Forty-four participants representing 8 countries participated in an online questionnaire with 12 participating in an online semi-structured interview.

Results

Themes generated reveal that obtaining a diagnosis and navigating the healthcare and education systems can be troublesome. Upon diagnosis, families tend to experience positive emotions such as relief. However, the daily challenges soon result in dominant negative emotional responses. DCD places significant financial burdens on families and impacts marital, parental and sibling relationships. Families often feel isolated from their communities as DCD is poorly understood.

Conclusion

DCD places families at risk as daily struggles require support which targets identified motor, cognitive, academic and emotional challenges. Creating awareness in society, education and healthcare would alleviate continual frustrations.

Contribution

This study provides insight into the wide-ranging impact that DCD has on families so that individualised support can be tailored, and general awareness raised.

Visual and kinesthetic motor imagery in adults with different degrees of self-reported motor coordination difficulties

Developmental Coordination Disorder (DCD) involves difficulties in performing coordinated movements with fine and/or gross motor skills deficits. Several studies showed that DCD is characterized by motor imagery deficits as well. Here we investigated in neurotypical adults (N = 334) the relationships between the ease of imaging two main motor imagery components, that is the visual and the kinesthetic one, self-reported motor coordination difficulties and handwriting speed. Self-reported motor difficulties were measured by the Adult Developmental Co-ordination Disorders/Dyspraxia Checklist (ADC) and scores were used to distinguish three groups: participants at risk of DCD (with both relevant childhood and current motor coordination difficulties); with motor coordination difficulties (relevant current but not childhood difficulties); without motor coordination difficulties (neither current nor childhood difficulties). The main results showed more kinesthetic and visual imagery difficulties in participants at risk of DCD than in those both with and without motor coordination difficulties. Interestingly, the relationships between the two imagery components and motor difficulties were different in the three groups, depending on: 1) the developmental phase (childhood or adulthood) to which motor coordination difficulties referred, and 2) the point of view (self or other), from which images were judged. Instead, no relationship was found between imagery abilities and handwriting speed. Thus, a nuanced pattern of the ease of imaging motor imagery emerged in adults with different degrees of self-reported motor coordination difficulties. These findings could be relevant for the assessment of people candidate to undergo a motor imagery training.

The Relationships between Self-Reported Motor Functioning and Autistic Traits: The Italian Version of the Adult Developmental Coordination Disorders/Dyspraxia Checklist (ADC)

BACKGROUND

We developed the Italian version of the adult developmental co-ordination disorders/dyspraxia checklist (ADC), providing reliability and concurrent validity data for the scale (Aim 1). In addition, we investigated the relationships between motor coordination difficulties and different autistic traits (Aim 2).

METHODS

498 participants (341 females; age range = 18-34) underwent the Italian version of the ADC, as well as a handwriting speed test, the autism spectrum quotient, the empathy quotient, and the systemizing quotient.

RESULTS

The distinction between three main factors (A, B, and C) identified in the original version of the ADC was confirmed here. Internal consistency of the ADC subscales was adequate, as well as the correlation with the handwriting speed test used to assess concurrent validity. No substantial sex differences on the ADC scores were found. Furthermore, data revealed that poor autistic-related communication skills and lower levels of systemizing tendencies were, among all the investigated autistic traits, those more strongly associated with higher motor coordination difficulties.

CONCLUSIONS

The Italian ADC seems a valuable tool for assessing motor coordination difficulties in adults and can reveal the nuanced impact exerted by different autistic traits on self-reported motor functioning.

[Formula: see text]Is active video gaming associated with improvements in social behaviors in children with neurodevelopmental disorders: a systematic review

Active video gaming (AVG) is a way that children with neurodevelopmental disorders can participate in social play and could be associated with improvements in social behaviors. However, limited research has investigated if AVG is associated with improvements in social behaviors in children and adolescents with neurodevelopmental disorders. A systematic literature search was conducted in Medline, Embase, Psycinfo, Cinahl, and Eric, Web of Science, and Scopus. Three main concepts were searched: exergaming, neurodevelopmental disorders, and social behaviors. Keywords and subject headings were used for each concept. 3080 articles were identified in the initial search in 2019; in January 2021, 167 additional articles were identified. Of these, 8 studies with 242 children with autism spectrum disorder, cerebral palsy, or developmental coordination disorder were included in this review. Six studies reported that participation in AVG was associated with improved social functioning, social interaction, emotional well-being, and social/emotional skills in children with ASD, CP, and DCD. In contrast, two studies that included children diagnosed with ASD did not find any association between AVG participation and social behaviors. The findings of this systematic review suggest that participation in an AVG intervention may be associated with improved social behaviors in children and adolescents with ASD, CP, and DCD. However, due to the limited number of studies included, this finding must be interpreted with caution. Future research is needed that examines the treatment fidelity of AVG in improving social behavior skills in children with neurodevelopmental disorders and the generalizability of these skills to real-life social situations.

The relationship between executive function, neurodevelopmental disorder traits, and academic achievement in university students

Difficulties with executive function have often been identified in individuals with various neurodevelopmental disorders such as Autism Spectrum Disorder (ASD), Attention-Deficit Hyperactivity Disorder (ADHD), and Developmental Co-ordination Disorder (DCD). Additionally, in childhood and adolescence, executive functioning is an important predictor of academic achievement. However, less research has explored these relationships in adult students, and those with a high level of neurodevelopmental disorder traits but no clinical diagnosis. Therefore, the current study aimed to assess whether ASD, ADHD, and DCD traits can predict academic achievement in university students, and whether traits of these neurodevelopmental conditions moderate the relationship between executive function and academic achievement. Both neurotypical students and those with a clinical diagnosis of a neurodevelopmental disorder were able to participate, with the majority being neurotypical. Participants completed four self-report questionnaires and provided a measure of academic achievement based on their university assignment results. Traits of ASD, ADHD, and DCD alone did not predict achievement, however, traits of ADHD and DCD significantly moderated the relationship between executive function and academic achievement. ASD traits did not significantly moderate this relationship. Implications and suggestions for future research are also discussed.

How are you getting by? Coping in developmental coordination disorder versus attention-deficit/hyperactivity disorder

Objective

Developmental Coordination Disorder (DCD) and Attention-Deficit/Hyperactivity Disorder (ADHD) persist into adulthood; however, little research exists to describe how adults with DCD and/or ADHD cope with their symptoms. Therefore, the purpose of this study was to investigate coping mechanisms reported by adults with DCD, ADHD, or both conditions. We expected there would be strategies specific to each condition and a broader scope of mechanisms reported by those with co-occurring DCD+ADHD.

Method

N = 161 participants completed the online survey, including n = 31 with DCD only, n = 116 with ADHD only, and n = 14 with DCD+ADHD.

Results

Most participants reported adaptive strategies. Of these, behavioral adaptations were most relevant to ADHD, while environmental modifications were common in DCD. Cognitive reframing and social support were similarly relevant to those with DCD and DCD+ADHD. Coping strategy categories were most uniform for the DCD+ADHD group.

Conclusions

Coping profiles highlight several noteworthy differences between DCD and ADHD which may be relevant for treatment.

Motor performance, praxis, and social skills in autism spectrum disorder and developmental coordination disorder

Previous research has shown that individuals with autism spectrum disorder (ASD) and developmental coordination disorder (DCD) may have overlapping social and motor skill impairments. This study compares ASD, DCD, and typically developing (TD) youth on a range of social, praxis and motor skills, and investigates the relationship between these skills in each group. Data were collected on participants aged 8–17 (n = 33 ASD, n = 28 DCD, n = 35 TD). Overall, the clinical groups showed some similar patterns of social and motor impairments but diverged in praxis impairments, cognitive empathy, and Theory of Mind ability. When controlling for both social and motor performance impairments, the ASD group showed significantly lower accuracy on imitation of meaningful gestures and gesture to command, indicating a prominent deficit in these praxis skills in ASD.

The adult developmental coordination disorders/dyspraxia checklist - German: adapted factor structure for the differentiation of DCD and ADHD

BACKGROUND

The Adult Dyspraxia/DCD Checklist (ADC) is the only existing self-report questionnaire to screen adults for potential Developmental Coordination Disorder (DCD). It was developed in English and Hebrew, however, its factor structure has not yet been assessed.

AIMS

The goals of the current study were to (1) develop and refine a German translation, (2) explore the emerging factors in a new and restructured ADC in German and apply this structure to an English ADC, and (3) explore its potential for distinguishing DCD versus ADHD.

METHOD

In a series of three studies, we assessed comprehensibility of the translation and revisions to the questionnaire. We further examined subscale structure in a sample of N = 148 individuals with DCD or ADHD and retested it in an English-speaking sample (N = 134).

RESULTS

Overall, we found decent reliability and construct validity for the German ADC. Three components emerged with themes of fine motor coordination, gross motor coordination, and executive functions which had strong psychometric properties in German and English.

CONCLUSIONS

The studies collectively highlight the German translation is effective and has strong potential to differentiate DCD and ADHD. Most notably, there are unique symptom profiles in motor and executive functioning difficulties in adults with DCD or ADHD. WHAT THIS PAPER ADDS?: The translation and preliminary validation of the German ADC in this study has the potential to screen for probable DCD in German-speaking adults for the first time. In addition, the new subscale structure can be generalized to the English version as well and allows for the potential assessment of several key symptomatic patterns in the realms of gross motor, fine motor, and executive functioning skills that differ between adults with DCD and ADHD. These differences were fairly consistent between English- and German-speaking samples, indicating potential for more widespread assessment and differentiation of DCD and ADHD.

The Role of Motor Coordination, ADHD-Related Characteristics and Temperament among Mothers and Infants in Exclusive Breastfeeding: A Cohort Prospective Study

Although exclusive breastfeeding is recommended for the first 6 months of life, breastfeeding rates are low. Motor skills and ADHD-related characteristics have not yet been examined as breastfeeding barriers. The aim of this study was to explore whether mothers' and infants' motor skills, mothers' ADHD-related characteristics and infants' temperament are associated with exclusive breastfeeding at 6 months after birth. Participants were 164 mothers and their infants recruited 2 days after birth. Mothers completed a demographic and delivery information questionnaire, the Infant Feeding Intentions Scale and the Iowa Infant Feeding Attitude Scale. At 6 months, mothers completed the Adult DCD (developmental coordination disorder)/Dyspraxia Checklist, the Adult ADHD (attention deficit hyperactivity disorder) Self-Report Scale Symptom Checklist-v1.1, and the Infant Characteristics Questionnaire, and provided information about their breastfeeding status. They were then divided into two groups accordingly: EBF (exclusive breastfeeding) and NEBF (non-exclusive breastfeeding). Infants were observed using the Test of Sensory Functions in Infants and the Alberta Infant Motor Scale. At 6 months, NEBF mothers reported higher prevalence of DCD (10.2% vs. 1.9%, χ2 = 5.561, p = 0.018) and ADHD (20.3% vs. 8.6%, χ2 = 4.680, p = 0.030) compared to EBF mothers. EBF infants demonstrated better motor coordination (t = 2.47, p = 0.016, d = 0.511), but no temperament differences compared to NEBF infants. Maternal DCD, ADHD and poor infant motor coordination are associated with non-exclusive breastfeeding and may become exclusive breastfeeding barriers. These findings may assist in identifying women at risk of not exclusively breastfeeding and encourage tailoring interventions for achieving higher exclusive breastfeeding rates.

Rethinking Social Relationships in Adulthood: The Differential Investment of Resources Model

Empirical evidence about the development of social relationships across adulthood into late life continues to accumulate, but theoretical development has lagged behind. The Differential Investment of Resources (DIRe) model integrates these empirical advances. The model defines the investment of time and energy into social ties varying in terms of emotional closeness and kinship as the core mechanism explaining the formation and maintenance of social networks. Individual characteristics, acting as capacities, motivations, and skills, determine the amount, direction, and efficacy of the investment. The context (e.g., the living situation) affects the social opportunity structure, the amount of time and energy available, and individual characteristics. Finally, the model describes two feedback loops: (a) social capital affecting the individual’s living situation and (b) different types of ties impacting individual characteristics via social exchanges, social influences, and social evaluations. The proposed model will provide a theoretical basis for future research and hypothesis testing.

Gender and age differences in the presentation of at-risk or probable Developmental Coordination Disorder in adults

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.

Cross-Cultural Adaptation and Preliminary Reliability of the Adolescents and Adults Coordination Questionnaire into European Spanish

Developmental Coordination Disorder (DCD) is a developmental disorder affecting motor coordination skills, that frequently persists into adolescence and adulthood. Despite this, very few instruments exist to identify DCD in this population, and none of them are available for Spanish young adults. The purpose of this study was to cross-culturally adapt and preliminarily validate the Adolescents and Adults Coordination Questionnaire (AAC-Q) into European Spanish. The AAC-Q was translated and adapted following international recommendations, including: (a) two independent forward translations; (b) synthesis and reconciliation; (c) expert committee review; and (d) a comprehensibility test. In addition, the internal consistency and homogeneity were examined using a sample of 100 Spanish higher education students. Cultural equivalence and idiomatic differences were addressed to produce the AAC-Q-ES. Findings show that the AAC-Q-ES is a cross-culturally adapted instrument with good preliminary reliability indicators in Spanish young adults (Cronbach’s α = 0.74; corrected item-total correlations = 0.217–0.504).

Motor and sensory features successfully decode autism spectrum disorder and combine with the original RDoC framework to boost diagnostic classification

Sensory processing and motor coordination atypicalities are not commonly identified as primary characteristics of autism spectrum disorder (ASD), nor are they well captured in the NIMH's original Research Domain Criteria (RDoC) framework. Here, motor and sensory features performed similarly to RDoC features in support vector classification of 30 ASD youth against 33 typically developing controls. Combining sensory with RDoC features boosted classification performance, achieving a Matthews Correlation Coefficient (MCC) of 0.949 and balanced accuracy (BAcc) of 0.971 (p = 0.00020, calculated against a permuted null distribution). Sensory features alone successfully classified ASD (MCC = 0.565, BAcc = 0.773, p = 0.0222) against a clinically relevant control group of 26 youth with Developmental Coordination Disorder (DCD) and were in fact required to decode against DCD above chance. These findings highlight the importance of sensory and motor features to the ASD phenotype and their relevance to the RDoC framework.

Perceptions of coordinated movement

BACKGROUND

Humans are highly social creatures who use others' movements to evaluate their social competencies. Smooth movement specifically signals an attractive, trustworthy or competent person. Those with Developmental Coordination Disorder (DCD), have peer relationship difficulties and lower sociometric preference scores. However, the relationship of perception of poor movement coordination to stereotyping has not been directly demonstrated.

AIM

We aimed to describe typically developing individuals' social stereotyping of individuals with and without DCD from minimal visual cues.

METHOD

3D motion capture tracked the movement of four 'targets' (two adult males with DCD and two male controls) in a variety of everyday scenarios. Kinematic footage of the target's movements was presented as a point-light-display to 319 typically developing adults who used The Rating Scale of Social Competence to report perceptions of the target's social competencies.

RESULTS

Targets with DCD were rated as having significantly lower social competence (M = 3.37, SD = 0.93) than controls (M = 3.46, SD = 0.89) t(269) = -5.656; p < 0.001, Cohen's d = 0.34.

DISCUSSION

Humans incorporate minimal information on movement fluency to evaluate others' social competencies, including individuals with DCD. Such stereotyping may be automatic and may be an ill-understood mechanism sustaining persistent rejection by peers for individuals with DCD and higher rates of loneliness, isolation and mental disorders. In addition, our study expands research on competence-based stereotyping to a new applied domain, confirming the minimal cues needed to initiate stereotyping of the competencies of others.

Poor Motor Performance - Do Peers Matter? Examining the Role of Peer Relations in the Context of the Environmental Stress Hypothesis

The aim of the current study was to investigate pathways of the Environmental Stress Hypothesis concerning the role of peer relations in the context of poor motor skills. First, we examined (1) the mediating role of peer problems in the association between motor performance in daily activities and internalizing problems as a main pathway of the Environmental Stress Hypothesis. Furthermore, we explored the role of (2) children's popularity as a mediator and (3) best friendship quality as a moderator path of the effect of motor performance on both peer problems and internalizing problems. The non-clinical sample of the present study consisted of 189 children (48.6% females) aged 9-11 years (M_age = 9.69, SD_age = 0.46). Parents reported on their child's motor performance in daily activities by completing the Developmental Coordination Disorder Questionnaire. The Strengths and Difficulties Questionnaire was used to assess peer problems as well as internalizing problems. The Self Description Questionnaire provided a measure of children's self-reported popularity. The Friendship Quality Questionnaire was used to investigate children's best friendship quality. Results of a structural equation model suggest that peer problems fully mediated the association between the motor performance in daily activities and both popularity and internalizing problems. However, no evidence for the mediating effect of popularity in the association between peer problems and internalizing problems was found. Further, best friendship quality had a non-significant moderating effect on the relation between peer problems and internalizing problems. The mediating role of peer problems highlights the importance of peer relations in the motor performance of daily activities. Schools and psychomotor interventions were suggested as practical implications to support children with poor motor performance in their relationship with their peers and to improve their motor performance in daily activities.
