To translate the Childhood Autism Rating Scale into Brazilian Portuguese and to determine the initial psychometric properties of the resulting version (CARS-BR).
The methodology used to produce an adequate version included translation, backtranslation and evaluation of semantic equivalence. In order to determine its psychometric properties (internal consistency, validity and reliability), the CARS-BR was administered to 60 consecutive patients with autism, aged between 3 and 17 years and seen at a university hospital.
Internal consistency was high, with a Cronbach's alpha of 0.82. Convergent validity, in comparison with the Autistic Traits Assessment Scale, exhibited a Pearson's correlation coefficient of r = 0.89. When correlated with the Global Assessment of Functioning Scale in order to evaluate discriminant validity, the CARS-BR exhibited a Pearson's coefficient of r = -0.75. Test-retest reliability exhibited a kappa coefficient of 0.90.
These results suggest that the CARS-BR is a valid and reliable instrument for evaluating autism severity in Brazil.
将《儿童孤独症评定量表》翻译成巴西葡萄牙语,并确定所得版本(CARS-BR)的初步心理测量学特性。
用于生成合适版本的方法包括翻译、回译和语义等效性评估。为了确定其心理测量学特性(内部一致性、效度和信度),对60名连续的自闭症患者进行了CARS-BR测试,这些患者年龄在3至17岁之间,在一家大学医院就诊。
内部一致性较高,克朗巴哈系数为0.82。与《孤独症特质评估量表》相比,收敛效度显示皮尔逊相关系数r = 0.89。为了评估区分效度,当与《总体功能评估量表》相关联时,CARS-BR显示皮尔逊系数r = -0.75。重测信度显示kappa系数为0.90。
这些结果表明,CARS-BR是巴西评估自闭症严重程度的有效且可靠的工具。
