The purpose of the present study was to examine the factor structure and psychometric properties of the Social Phobia and Anxiety Inventory for Children (SPAI-C), an instrument developed in the United States and applied to a sample of Brazilian schoolchildren. The process included the translation of the original material from English into Portuguese by two bilingual psychiatrists and a back translation by a bilingual physician. Both the front and back translations were revised by a bilingual child psychiatrist. The study was performed using a cross-sectional design and the Portuguese version of the SPAI-C was applied to a sample of 1954 children enrolled in 3rd to 8th grade attending 2 private and 11 public schools. Eighty-one subjects were excluded due to an incomplete questionnaire and 2 children refused to participate. The final sample consisted of 1871 children, 938 girls (50.1%) and 933 boys (49.8%), ranging in age from 9 to 14 years. The majority of the students were Caucasian (89.0%) and the remainder were African-Brazilian (11.0%). The Pearson product-moment correlation showed that the two-week test-retest reliability coefficient was r = 0.780 and Cronbach's alpha was 0.946. The factor structure was almost similar to that reported in previous studies. The results regarding the internal consistency, the test-retest reliability and the factor structure were similar to the findings obtained in studies performed on English speaking children. The present study showed that the Portuguese language version of SPAI-C is a reliable and valid measure of social anxiety for Brazilian children.
本研究的目的是检验儿童社交恐惧症与焦虑量表（SPAI-C）的因子结构和心理测量特性，该量表是在美国开发并应用于巴西学童样本的一种工具。过程包括由两位双语精神科医生将原始材料从英文翻译成葡萄牙文，以及由一位双语医生进行回译。前后翻译均由一位双语儿童精神科医生修订。本研究采用横断面设计，将葡萄牙语版的SPAI-C应用于就读于2所私立学校和11所公立学校的1954名三至八年级儿童样本。由于问卷不完整，81名受试者被排除，2名儿童拒绝参与。最终样本包括1871名儿童，其中938名女孩（50.1%）和933名男孩（49.8%），年龄在9至14岁之间。大多数学生是白种人（89.0%），其余为非裔巴西人（11.0%）。皮尔逊积差相关显示，两周重测信度系数r = 0.780，克朗巴哈系数α为0.946。因子结构与先前研究报告的结构几乎相似。关于内部一致性、重测信度和因子结构的结果与在以英语为母语的儿童中进行的研究结果相似。本研究表明，葡萄牙语版的SPAI-C是测量巴西儿童社交焦虑的一种可靠且有效的工具。
