Abstract: Objective To examine the reliability and validity of Developmental Coordination Disorder Questionnaire-Chinese version(DCDQ-C),and to provide an effective population-based screening tool for developmental coordination disorder.Methods A total of 3 316 children from 10 nursery schools in Suzhou city of mainland China were involved in the study.Cronbach'α was used to determine internal consistency.Test-retest reliability of the MABC-2 was estimated using Pearson Correlation Coefficieynt.The content validity was evaluated by the item-level content validity index (I-CVI).Both exploratory and confirmatory factor analysis was used to examine the construct validity of the MABC-2 test.Receiver Operating Characteristic (ROC) analysis was used to measure the Area Under Curve (AUC) value of the DCDQ-C as a screening instrument.Results The Results showed that both internal consistency (Cronbach'α value of all items were above 0.85) and test-retest reliability (13 items were above 0.9) were excellent.I-CVIs of all items were above 0.78,and suggested a fair content reliability of DCDQ-C.Exploratory factor analysis showed that almost all factor loadings of each items were above 0.7,and indicated a satisfactory construct validity.ROC analysis shows a comparative small AUC (0.641).Conclusions The Chinese version of the DCDQ has satisfactory internal consistency and reliability.However,it should be cautioned when used in younger preschool children.

摘要： 目的 进行发育性协调障碍问卷中文版(DCDQ-C)的信效度评价,为进一步在中国大陆地区开展发育性协调障碍早期筛查提供有效的筛查工具。方法 苏州市区的10所幼儿园共3 316名儿童纳入研究。采用Cronbach' α系数来确定内部一致性信度,Person相关系数评价DCDQ-C的重测信度,项目水平内容效度指数(I-CVI)评价内容效度。探索性因素分析来检验DCDQ-C测试的结构效度。采用工作者曲线(ROC)下面积分析DCDQ-C的诊断价值。结果 DCDQ-C内部一致性(所有项目Cronbach' α值均>0.85)和重测信度(13项相关系数均在0.9以上)都非常高。所有项目的I-CVI均>0.78,表明DCDQ-C内容的可靠性价高。探索性因素分析的因子载荷基本均在0.7以上,提示DCDQ-C的结构效度较高。DCDQ-C的ROC曲线下面积与0.5具有统计学差异(P<0.05),但曲线下面积不高(0.641),去除低年龄组后ROC曲线下面积略有增加。结论 中文版本的DCDQ在中国儿童中应用性较好,但在小年龄段的学龄前儿童使用时仍需谨慎。
