Evaluation of the Developmental Coordination Disorder Questionnaire as a screening instrument
Developmental Medicine & Child Neurology, 2006
Disorder Questionnaire (DCD-Q) in a random sample of 608 children aged 4-12 years (mean age 7.8 (SD 2.4); 311 boys/297 girls), a sample of 55 children with DCD aged 4-12 years, referred to a rehabilitation clinic (mean age 8.3 (SD 2.0); 48 boys/7girls) and a control sample matched for age and gender. The DCD-Q proves to be reliable and valid both in the age range for which the questionnaire was developed and in a younger age range (4-8 years). Sensitivity and specificity of the DCD-Q was assessed using the Movement ABC as gold standard. The DCD-Q meets standards for sensitivity in the clinic-referred sample, but not in the random sample. Specificity almost reaches the desired standard of 90% in both samples.

Background: Children with Developmental Coordination Disorder (DCD) have deficits in fundamental motor skills (e.g. catching, flinging, jumping and running) and complex motor skills (related to the contexts of sports, games and leisure) when compared to their typically developing peers. These deficits may compromise motor performance, impacting the daily life functionality of these children. In addition, different levels of motor performance can be observed within this motor disorder because DCD is a complex and multifactorial condition. As example, moderate and severe DCD are common terminologies used in the field, to classify children <16°percentile and <5°percentile in motor performance assessment related to DCD, respectively. Thus, evaluating the motor performance of these children with specific instruments is essential for the identification of impairment and provision of effective intervention. Yet, given the specificities across instruments available to assess motor performance along with the complex features surrounding children with DCD, differences among those instruments should compose the purpose of investigations in the motor skills field during childhood. Purpose: To compare the motor performance of Brazilian children with severe DCD (s-DCD) and moderate DCD (m-DCD) using two motor assessment instruments: the Movement Assessment Battery for Children-Second Edition (MABC-2) and the Körperkoordinationstest Für Kinder (KTK). A total of 123 children, 66 with s-DCD and 57 with m-DCD, with a mean age of 8.7 (± 0.85) years were evaluated in this cross-sectional study. Results: No significant difference was found between the mean percentiles of the general motor performance of the children in the MABC-2 and KTK tests (p = 0.06). We observed significant correlations between the MABC-2 and KTK tests, ranging from 0.17 (very weak) to 0.47 (moderate). The strongest correlation was observed between the MABC-2 Balance component score and the KTK MQ Walking backwards (r = 0.47). The majority of children with s-DCD were classified as impaired, and the minority were classified as normal in the KTK test. Yet, the majority of those with m-DCD were classified as normal in the KTK test. An independent t-test showed a significant difference for most of the comparisons performed between the s-DCD and m-DCD groups. Conclusion: As expected, children with s-DCD scored lower in all MABC-2 components as well as in the quotients of KTK. Thus, the analysis of motor performance by the MABC-2 and KTK indicated that Brazilian children with ARTICLE HISTORY
Psychometric Properties of the Revised Developmental Coordination Disorder Questionnaire
Physical & Occupational Therapy in Pediatrics, 2009
The Developmental Coordination Disorder Questionnaire (DCDQ) is a parent completed measure designed to identify subtle motor problems in children 8 to 14.6 years of age. The purpose of this study was to extend the lower age range to children aged 5 to 7 years, revise items to ensure clarity, develop new scoring, and evaluate validity of the revised questionnaire. Additional items with improved wording were generated by an expert panel. Analyses of internal consistency, factor loading, and qualitative/quantitative feedback from researchers, clinicians and parents were used to select 15 items with the strongest psychometric properties. Internal consistency was high (alpha = .94). The expanded questionnaire was completed by the parents of 287 children, aged 5-15 years, who were typically developing. Logistic Regression Modelling was used to generate separate cut-off scores for three age groups (overall sensitivity = 85%, specificity = 71%). The Revised DCDQ was then compared to other standardized measures in a sample of 232 clinically-referred children. Differences in scores between children with and without DCD provide evidence of construct validity (F (1,230) = 81.7, p < .001). Concurrent validity is evident with the Movement Assessment Battery for Children (r = .55) and the Test of Visual Motor Integration (r = .42). The Revised DCDQ can be considered a valid clinical screening tool for children.
Evaluation of a screening instrument for developmental coordination disorder
Journal of Adolescent Health, 2004
Methods: A sample of 209 children (M ؍ 121; F ؍ 87) consented to the BOTMP test, CSAPPA scale, Participation Questionnaire, Léger 20-meter Shuttle Run, and body fat using bioelectric impedance. Receiver Operating Characteristic (ROC) curve analysis and Kappa statistic were used to validate the CSAPPA scale as a predictor for significant clumsiness on the BOTMP test. Results: Prevalence of DCD was .09 ؎ .03 of both males and females, all previously undiagnosed. A positive cutoff of < 47 and < 53 for DCD on the CSAPPA scale was identified in male and females, respectively. Both gender cut-offs demonstrated significant agreement (p < .01) with a positive BOTMP test. Males' results indicated a sensitivity and specificity values of .90 (CI ؍ .18) and .89 (CI ؍ .22). Likewise, the female subject cutoff demonstrated high sensitivity [.88 (CI ؍ .05)] and specificity [75 (CI ؍ .09)]

Developmental Coordination Disorder (DCD) is an important risk factor in the development of children that can have a significant academic and social impact. This reinforces the need for its timely identification using appropriate assessment methods and accurate screening tests. The commonly used standardized motor test for the DCD identification is the Movement Assessment Battery for Children-Test (M-ABC Test) (Henderson & Sugden, 1992). The aim of the present study was to examine if the M-ABC Test can be considered to be the “gold standard” for the motor assessment of children with the aforementioned disorder. For that purpose, a critical review of the extant literature regarding M-ABC Test's psychometric properties was conducted. Neither the test manual nor the studies reviewed provide support for the reliability and validity of the M-ABC Test results in children with DCD. Until sufficient evidence for its technical adequacy is accumulated, the M-ABC Test should not be used in isolation for children with DCD.

Background The Developmental Coordination Disorder Questionnaire (DCDQ'07) discriminates children with Developmental Coordination Disorder (DCD) from their peers. Studies employing the DCDQ have typically used clinical samples. To further validate the DCDQ'07, this study: (1) described its distributions in a population-based sample, and a sample of children with DCD; (2) explored sex and age differences at important cut-points; and (3) examined its factor structure. Methods This secondary analysis of data collected from 23 schools (n = 3151) included a sample of 3070 children (1526 boys, 1544 girls) and a sample of 122 children (73 boys, 49 girls) who met DCD diagnostic criteria. DCDQ'07 distributions were described by age and sex. Chi-square analyses were conducted using three clinically important percentile ranges; a factor analysis explored the construct validity of DCDQ scores. Results Parents of 3070 children (97.4%) completed the questionnaire independently. Significant sex differences were noted in both samples. Significant differences in proportions by sex, and DCDQ means by age were found in the population sample. A three-factor solution was found, accounting for 70.3% of the variance. Conclusions This is one of the largest studies using the DCDQ'07 with a non-clinical sample. The three-factor solution, including item loading, was consistent with previous research. When using DCDQ cut-offs it is important to consider sex and age.

Aim: Parental screening of children's motor skills can be helpful for early identification of Developmental Coordination Disorder (DCD). The present study examined the associations between the Developmental Coordination Disorder Questionnaire-Brazilian version (DCDQ-BR) and motor competence in school-age children. Methods: 707 children (332 boys, 375 girls) aged between 6-to 10-years and one of their parents participated in the study. Parents completed the DCDQ-BR and children's motor competence was determined using the Bruininks-Oseretsky Test of Motor Proficiency-2nd edition (BOT-2). Results: The agreement between the BOT-2 and DCDQ-BR results was comparable across age, ranging from 74-84 percent. In general, there were low-to moderate correlations between all aspects of the parent report and children's motor competence. Sensitivity and specificity of the DCDQ-BR were 70% and 81%, respectively. Overall, boys had higher motor competence than girls, but parent reports were similar for gender. Conclusions: Parental assessment of their child's motor ability is moderately associated with motor competence, and this association is similar for boys and girls, even though boys scored higher in motor competence. Our findings suggest that it may be possible to reduce the length of clinical assessment by only testing children that flag as suspect for DCD in the DCDQ-BR.

Background Previous studies have emphasized the importance of early identification of children with Developmental Coordination Disorder (DCD) to prevent the development of secondary academic, emotional and social manifestations of the disorder. The aim of this study was to develop a valid parent and teacher questionnaire -the Children Activity Scales for parents (ChAS-P) and for teachers (ChAS-T) -to identify children aged 4-8 years at risk for DCD and to examine the reliability and validity of these questionnaires. Methods The questionnaires' content and face validity were established, and then cut-off scores were determined based on responses of 355 teachers and 216 parents. Internal consistencies were also calculated. Factor analyses were performed, and construct validity was determined by examining the questionnaires' ability to discriminate between 30 children aged 5-6.5 years diagnosed with DCD and 30 typically developing children. Concurrent validity was examined by comparing questionnaire scores with those of the Movement Assessment Battery for Children (M-ABC).
The latest guidelines recommend early identification of children with motor impairments using a standardized norm-referenced test. Motor coordination difficulties in developmental age have been studied extensively over recent years, with experimental literature on developmental coordination disorder (DCD) suggesting that motor proficiency assessments depend on the nature of the task at hand. In this article we reviewed 14 assessment tools to measure movement performance in childhood and adolescence, which are often referred to in an international context. This updated review aims to compare motor tests depending on a) the nature of the tasks included in the battery (i.e., questionnaire and clinical examination), b) psychometric properties, and c) cultural adaptation to relevant developmental norms. Finally, implications for diagnosis and clinical practice are discussed. Considering there are several tests used for DCD, it is important to better define their reliability and validity in different cultures in order to better compare the validation studies and select the most appropriate test to use in the assessment procedure.

This study systematically reviewed the clinical and psychometric properties of manual function outcome measures for children with developmental coordination disorder (DCD) aged 3-18 years. Three electronic databases were searched to identify manual function tools at the ICF-CY body function, activity and participation level used in children with DCD. Study selection and data extraction was conducted by two blind assessors according to the CanChild Outcome Measures Rating Form. Nineteen clinical tests (seven fine hand use tools and 12 handwriting measures), three naturalistic observations and six questionnaires were identified. The fine-motor subdomain of the Movement Assessment Battery for Children, the Bruininks-Oseretsky Test of Motor Proficiency-2 and the Functional Strength Measurement, with adequate reliability and validity properties, might be useful for manual function capacity assessment.
