Applicability of the developmental coordination disorder questionnaire for children in Serbia
Specijalna edukacija i rehabilitacija, 2018
The aim was to evaluate the applicability of the Developmental Coordination Disorder Questionnaire (DCDQ) adapted for use on the population of children in Serbia. The sample consisted of 901 children (age range 60-168 months) who did not have problems with coordination and the clinical sample of 58 children (age range 60-108 months). The parents assessed their child's coordination rating it on a 5-point Likert scale. Internal consistency of the instrument was 0.94, item-correlations were as high as over 0.70, test-retest reliability was good (r=0.97, p=0.00). The results revealed a significant positive correlation between the total questionnaire score and age (r=0.28, p=0.00). Factor analysis confirmed three-factor structure. The questionnaire had good sensitivity (98%) and specificity (78%). The DCDQ applied on Serbian children has a potential to be a reliable and valid instrument for screening children with coordination problems.

Purpose: The revised version of Developmental Coordination Disorder Questionnaire (DCDQ'07) is a widely used parent-reported screening tool for DCD. The tool is not available in any Indian language. This article reports on the results of the cross-cultural validation of DCDQ'07 into Kannada, a South Indian language. Methods: The questionnaire was first translated into Indian English to overcome differences in phraseology between Canadian and Indian English (DCDQ'07-IE). Following this, forward translation, synthesis, back translation, expert committee review, and pre-testing of the translated version were conducted to obtain the Kannada version of the questionnaire (DCDQ'07-K). Minor examples, in keeping with local usage, were added. 160 parents were recruited, among whom 80 were parents of children with motor difficulties and 80 were parents of children without motor difficulties. They rated their children on DCDQ'07-IE. After a washout period of 2 weeks, the same parents once again rated their children on DCDQ'07-K.Statistical analysis for reliability, construct validity, and Rasch diagnostics (person and item reliability, fit statistics, category functioning of scores and person-item map) were conducted. Results: Internal consistency (Cronbach's Alpha>0.8), parallel form test-retest reliability (ICC=0.95 at 95% CI) and floor and ceiling were acceptable. Principal component analysis (PCA) showed three factors accounting for total variance of 59.29% and 58.80% in DCDQ'07-IE and DCDQ'07-K respectively. Item reliability (<0.8) and separation index (<2) were poor in both versions. Category

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.
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.

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.

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.

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). ...
