Abstract
Background and purpose: The prevalence of Developmental Coordination Disorder (DCD) is estimated as 4% to 10%. In Taiwan, the prevalence of DCD between age of 7 to 8 is about 3.5%, and that between age of 9 to 10 is about 17.9%. According to the census of Ministry of Education in Taiwan between 2004 and 2005, there are about 1.88 million school-aged children. It is estimated that about 7 to 34 thousand students need professional support and intervention. How to detect children suffering from coordination disorders for timely intervention is thus an important issue for professionals working with children. However, there is still no gold standard for identifying these children. Furthermore, there has been a concern about a lack of standardized instruments for screening children with motor coordination problems. The purpose of Study 1 was to illustrate the translation procedure and to assess the reliability and the factor structure of the Chinese version of Developmental Coordination Disorder Questionnaire(DCDQ). The purpose of Study 2 was to examine the discriminant validity, concurrent validity, sensitivity and specificity of the Chinese version DCDQ.
Method: Study 1: With Wilson’s permission, a committee consisting of five faculty members who were specialized in sensory integration theory and treatment translated the DCDQ into Chinese. After the committee confirmed the original version, translated version, and back-translated version, the Chinese DCDQ was administered to 1562 students from Grade 1 to 3 in five primary schools in Taipei. One week later, 1388 questionnaires were returned. In order to examine test-retest reliability, 42 parents were asked to fill out the questionnaires again with a 2-week interval. Thirty-seven parents returned the questionnaires. Study 2: The participants were from a larger study which was to investigate sensory integrative function in children with Developmental Coordination Disorder. One hundred and seventeen children who were from eight schools and had parental consent participated in this study. They were tested individually in two sessions with a two-to five-day interval by testers who had received a rigorous training of the test administration of the BOTMP and the MABC and were blind to the DCDQ-C scores of children.
Results: Study 1: The results showed significant difference on the total scores of the Chinese DCDQ between girls and boys(F = 12.32, p < 0.001, df = 1), but no significant differences main effect of grade (F = 0.509, p = 0.601, df = 2) and interaction effect between sex and grade(F = 0.028, p = 0.972, df = 2). The Cronbach’s α coefficient for the Chinese DCDQ was 0.84 indicating high internal consistency. The test-retest reliability was 0.93. The result of exploratory factor analysis showed that the Chinese DCDQ contained three factors. The first factor, “Control during movement”, accounted for 38.62% of the total variance. The second factor, “Fine motor/Handwriting”, accounted for 6.27% of the total variance. The third factor, “Coordination dysfunction”, accounted for 5.51% of the total variance. Study 2: An ANOVA revealed significant group differences on the total score of the Chinese DCDQ(F = 6.65, p = 0.002, df = 2). Post-hoc group comparisons showed that the non-DCD group scored significant higher than the DCD(p = 0.004) and the suspect DCD group(p = 0.049). As to the concurrent validity, the total score of the Chinese DCDQ showed low to moderate correlated with the three scores of the BOTMP(r = 0.272 to 0.423, p < 0.01), and moderate correlated with the total impairment score of the M-ABC(r = -0.450, p < 0.01). The sensitivity of the Chinese DCDQ ranged from 22%-47%, and the specificity of the Chinese DCDQ ranged from 77%-90%.
Conclusion: The reliability and validity of the Chinese DCDQ appeared to be acceptable for use on children aged from 6 to 9 years in Taiwan. This study showed that the Chinese DCDQ could be a useful motor coordination screening tool in an epidemiological survey.
