To perform a psychometric analysis of the Brazilian version of the Brief Social Phobia Scale (BSPS).
Hundred and seventy-eight university students of both genders aged on average 21.2 years and identified as Social Anxiety Disorder (SAD) cases and non-cases was studied, with the structured clinical interview for DSM-IV being used as a parameter. The different instruments were applied in an individual manner in the presence of a rater and of an observer.
The BSPS showed adequate internal consistency (0.48-0.88) and concurrent and divergent validity with the Beck Anxiety Inventory (BAI) (0.21-0.62), Social Phobia Inventory (0.24-0.82) and Self Statements During Public Speaking Scale (SSPS) (0.23-0.31). Discriminative validity revealed a sensitivity of 0.88-0.90 and a specificity of 0.81(0.83 for cut-off notes of 18/19. Factorial analysis demonstrated the presence of six factors that jointly explained 71.79% of data variance. Construct validity indicated some limits of the scale regarding the diagnosis of SAD. Inter-rater reliability was strong (0.86-1.00, p<0.001).
The BSPS is adequate for use with university students, although further studies in different cultures, samples and contexts are still necessary.
对巴西版Brief Social Phobia Scale（BSPS）进行心理测量学分析。
研究了 178 名平均年龄为 21.2 岁的男女大学生，他们被确定为社交焦虑障碍（SAD）病例和非病例，并使用 DSM-IV 结构化临床访谈作为参数。不同的工具在评估者和观察者在场的情况下以个体方式进行应用。
BSPS 显示出适当的内部一致性（0.48-0.88）和与 Beck 焦虑量表（BAI）（0.21-0.62）、社交恐惧症量表（0.24-0.82）和公开演讲时自我陈述量表（SSPS）（0.23-0.31）的同时和发散效度。判别效度显示敏感性为 0.88-0.90，特异性为 0.81（0.83 为 18/19 的截断值）。因子分析显示存在六个因子，共同解释了 71.79%的数据方差。结构效度表明该量表在社交焦虑障碍的诊断方面存在一些限制。评估者间信度较强（0.86-1.00，p<0.001）。
BSPS 适用于大学生使用，但仍需要在不同文化、样本和背景下进行进一步研究。
