ABSTRACT
Objective To study the reliability and validity of the Chinese version of the dynamic occupational 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 construction 0. 844 and thinking operations 0. 630. The ICC for intra-rater reliability was 0. 991 and for inter-rater reliability it was 0. 989. Using the Binet intelligence test as a benchmark, the Pearson correlation coefficient between the IQ values and the total DOTCA-Ch scores was 0. 872 for 6 year-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.
