中文版儿童作业疗法认知功能动态评定量表信度和效度的初步研究

The reliability and validity of the Chinese version of dynamic occupational therapy cognitive assessment for children

目的确定中文版儿童作业疗法认知功能动态评定量表（DOTCA—Ch）的信度和效度，为其临床应用提供理论依据。方法将英文版DOTCA—Ch翻译成中文。选取佳木斯市某小学109名学生，分别用中文版DOTCA-Ch和中国一比内智力测验法进行评定。以中国一比内智力测验法作为校标分析校标效度，采用因子分析方法进行结构效度分析，采用组内相关系数（ICC）分析方法进行测量者内信度和测量者间信度分析，应用Cronbacha系数进行内部一致性检验。结果内部一致性检验：DOTCA—Ch总Cronbach α系数为0．8920，测量者内总ICC为0．991，测量者间总ICC为0．989。在旋转后的因子负荷阵中，各领域在一个公因子中有较高负荷。将采用中国一比内智力测验法所得智商与DOTCA—Ch评分进行相关性分析，6岁组智商与总分的相关系数为0．872，11～12岁组智商与总分相关系数为0．870。结论中文版DOTCA—Ch具有良好的信度和效度，可以作为一种有效测量工具来评定儿童认知功能。

Objective To study the reliability and validity of the Chinese version of the dynamic occu- pational therapy cognitive assessment for children （DOTCA-Ch）. Methods The English version of the DOTCA-Ch was translated into Chinese. One hundred and nine students from the city of Jiamusi were assessed with the Chinese Binet intelligence test and the DOTCA-Ch. Intra-class correlation coefficients （ICCs） were used in inter-rater and intra-rater reliability assessments. Cronbach＇s alpha coefficient was used to assess internal consistency. Factor analysis was used to assess construct validity. Pearson correlation coefficients were used in assessing criterion-related validity. Results The total ICC of the DOTCA-Ch was 0. 892. Cronbach＇s alpha coefficients for the subtests were orientation 0. 713; spatial perception 0. 793; praxis 0. 850; visuomotor con- struction O. 844 and thinking operations O. 630. The /CC for intra-rater reliability was O. 991 and for inter-rater reliability it was 0. 989. Using the Binet intelligence test as a benchmark, the Pearson correlation coefficient be- tween the IQ values and the total DOTCA-Ch scores was 0. 872 for 6 ycar-olds, but 0. 870 for 11 and 12 yearolds. Factor analysis revealed an acceptable set of 5 common factors. Their cumulative contribution was 67%. Conclusions The Chinese version of the DOTCA-Ch is reliable and valid. It can be used as an effective measuring tool to evaluate children＇s cognitive functioning.
