It is believed that social phobia has its onset during adolescence and precedes other mental disorders; it is thus important to investigate the condition among young people. To date there is no self-reported scale validated for the Brazilian population. The present study investigated the reliability of the Portuguese-language version of the Social Phobia Inventory (SPIN) among adolescent students from public schools in the city of Rio de Janeiro. After SPIN was translated into Portuguese, a test-retest reliability study was carried out with 190 students. Intra-class correlation coefficient (ICC) and weighted kappa (kappaw2) were estimated, log-linear models were fitted, and Bland & Altman graphs were built. The Portuguese version showed good internal consistency (Cronbach's alpha=0.88) and good reliability for total score (ICC=0.78). Reliability for single items was not very good (kappaw2 between 0.32 and 0.65). The "semi-association" model fit most of the items best. Based on these findings we concluded that the Portuguese-language version of SPIN showed good reliability results, similar to those obtained with the original English-language version.
人们认为社交恐惧症在青春期发病，且早于其他精神障碍；因此，在年轻人中研究这种疾病很重要。迄今为止，尚无针对巴西人群验证的自我报告量表。本研究调查了社交恐惧症量表（SPIN）葡萄牙语版本在里约热内卢市公立学校青少年学生中的信度。SPIN被翻译成葡萄牙语后，对190名学生进行了重测信度研究。估计了组内相关系数（ICC）和加权kappa（kappaw2），拟合了对数线性模型，并绘制了布兰德-奥特曼图。葡萄牙语版本显示出良好的内部一致性（克朗巴赫α系数=0.88）和总分的良好信度（ICC=0.78）。单个项目的信度不是很好（kappaw2在0.32至0.65之间）。“半关联”模型对大多数项目拟合最佳。基于这些发现，我们得出结论，SPIN葡萄牙语版本显示出良好的信度结果，与原始英语版本获得的结果相似。
