Psychometric Properties of the Little Developmental Coordination Disorder Questionnaire–Taiwan (original) (raw)

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.

Development of the Little Developmental Coordination Disorder Questionnaire for preschoolers and preliminary evidence of its psychometric properties in Israel

Research in Developmental Disabilities, 2011

The early identification of motor coordination challenges before school age may enable close monitoring of a child's development and perhaps ameliorate some of the social, psychological and behavioral sequela that often accompany unrecognized Developmental Coordination Disorder (DCD). The purpose of this study was to develop and assess the initial psychometric properties of a screening tool, the Little DCD Questionnaire (Little DCDQ), designed to identify DCD amongst preschoolers aged 3 and 4. Methods: The suitability of the items of the DCDQ'07 for 3-and 4-year-old children was assessed. Four items were found to be suitable and new items were generated. Content validity was ensured using a Table of Specification and the items were categorized into three sub-categories (Control During Movement, Fine Motor and General Coordination). The Little DCDQ was administered to 146 children (91 boys) aged 3 and 4 (mean age = 49.39 AE 7.16 months). Ninety-one typically developing children were included (mean age = 47.80 AE 7.05 months; 46 boys) while 55 children had been referred or were being treated for some form of developmental delay (mean age = 52.02 AE 6.60 months; 45 boys). Of this sample, 28 parents completed the questionnaire twice within a 2-week interval. Results: Test-retest reliability was evidenced by moderate to good intraclass correlation coefficient values between scores on the two administrations for the total and the three sub-category scores. Evidence of internal consistency was provided by adequate to high Cronbach's alpha coefficients calculated for each item, each sub-category score and the total score for the total group, and separately for the control group and the clinically referred group. Validity evidence based on relations to other variables was provided by the finding of significant group differences (clinically referred and control) for the total and sub-category scores for both the age groups and the total group. Conclusions: Based on the preliminary psychometric evidence, it appears that the Little DCDQ meets many of the necessary standards for validity and reliability as a screening instrument, and shows promise as a useful clinical and research tool.

Descriptive and factor analysis of the Developmental Coordination Disorder Questionnaire (DCDQ‘07) in a population-based sample of children with and without Developmental Coordination Disorder

Child: Care, Health and Development, 2014

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.

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.

Identifying Children with Developmental Coordination Disorder via Parental Questionnaires. Spanish Reference Norms for the DCDDaily-Q-ES and Correlation with the DCDQ-ES

International Journal of Environmental Research and Public Health, 2020

Developmental Coordination Disorder (DCD) is one of the most prevalent neurodevelopmental disorders in school-aged children, with major consequences in psychosocial and physical health. Adequate identification of this disorder is necessary to prompt effective interventions. The aims of this study were to develop the Spanish adjusted reference norms for the DCDDaily-Q and to test the correlation and agreement between the Spanish versions of the DCDDaily-Q (DCDDaily-Q-ES) and the Developmental Coordination Disorder Questionnaire (DCDQ-ES), two reliable instruments to assess motor performance and DCD. Clinically relevant percentiles were calculated for the DCDDaily-Q-ES using a representative sample of Spanish children aged 5 to 10 years (n = 356; M = 7.3 years, SD = 1.8; boys = 50%). Pearson’s correlation coefficient and intraclass correlation coefficient (ICC) were used to determine correlation and agreement between questionnaires, respectively. A moderate and significant correlation...

Cross-cultural adaptation, reliability and predictive validity of the Italian version of Developmental Coordination Disorder Questionnaire (DCDQ)

European Journal of Paediatric Neurology, 2013

Cross-cultural adaptation Parent's questionnaire Diagnosis Motor impairment a b s t r a c t Background: Developmental coordination disorder (DCD) is a motor disorder of unclear etiology that severely interferes with a child's ability to perform daily motor tasks. As a useful alternative to a time-consuming motor test and specialist evaluation, parents or teachers can complete motor questionnaires. A tool used worldwide to screen motor performance in 4-to 14-year-old children is the Developmental Coordination Disorder Questionnaire 2007 (DCDQ'07). Aims: To describe how we translated the Developmental Coordination Disorder Questionnaire 2007 (DCDQ'07) and adapted it to the Italian population and to test its preliminary psychometric properties in Italian children. Methods: Parents of a clinical group of 26 children (5e11 years old) with a diagnosis of DCD and 52 matched controls completed the DCDQ translated into Italian and adapted for cross-cultural purposes according to current guidelines. Twenty-four parents of typically developing children randomly selected completed the questionnaire twice to examine test eretest reliability.

Cross-cultural adaptation of the Developmental Coordination Disorder Questionnaire for brazilian children

Revista Brasileira De Fisioterapia, 2009

BACKGROUND: Developmental Coordination Disorder (DCD) is considered a major health problem among school-aged children worldwide. Although there are several instruments to identify children with DCD, none of them are translated into Portuguese and validated to be used in Brazil. OBJECTIVES: Considering that a parent questionnaire is a simple and effective method to screen children with DCD, this study describes the adaptation of the Developmental Coordination Disorder Questionnaire (DCDQ) and the pilot testing with Brazilian children. METHODS:Translation of the DCDQ into Portuguese was conducted according to current guidelines for cross-cultural adaptation of instruments. The questionnaire was completed by parents of 15 children with motor coordination problems and parents of 30 children who were typically developing, matched for age. Five parents randomly selected from each group completed the questionnaire twice, to examine test-retest reliability. The parent's opinion regarding the quality of the questionnaire was recorded. RESULTS: 91% of Brazilian parents reported no difficulty in completing the DCDQ. Examination of psychometric properties revealed that two items had limitations due to cultural differences. After item substitution, sensitivity increased from 0.66 to 0.73 and test-retest reliability from 0.95 to 0.97. Internal consistency also increased from 0.91 to 0.92. CONCLUSIONS:The translated instrument shows potential as a screening tool for children in Brazil and should be further examined. Research with a larger sample is needed in order to define cut-off scores and verify the instrument's validity and clinical utility. The use of the DCDQ will allow the comparison of epidemiological data from different countries.

The development and standardization of the Children Activity Scales (ChAS-P/T) for the early identification of children with Developmental Coordination Disorders

Child: Care, Health and Development, 2006

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).

Psychometric Validation and Reference Norms for the European Spanish Developmental Coordination Disorder Questionnaire: DCDQ-ES

International Journal of Environmental Research and Public Health

The Developmental Coordination Disorder Questionnaire (DCDQ) is a widely used and well-validated tool that contributes to the diagnosis of Developmental Coordination Disorder (DCD). The aim of this study was to further analyze the psychometric properties of the European Spanish cross-culturally adapted version of the Developmental Coordination Disorder Questionnaire (DCDQ-ES) in a sample of Spanish children aged 6–11 years and to establish reference norms with respect to age groups. Parents of 540 typically developing children completed the DCDQ-ES. A second sample of 30 children with probable DCD (pDCD) was used to test its discriminant validity. Confirmatory factor analysis supported the original three-factor structure and the internal consistency was excellent (Cronbach’s α = 0.907). Significant differences between age groups were found. The pDCD group scored significantly lower than the reference sample in the three subscales and DCDQ-ES total score (p < 0.001; AUC = 0.872). ...
