The Dental Fear Survey (DFS), a paper and pencil instrument for assessing dental fear and avoidance, has been widely used and validated in fear studies in the US. However, before such instruments are used in countries and cultures dissimilar to the one in which it was developed, they should be cross-validated in that culture. The present study is an examination of the DFS response characteristics in a group of 374 Brazilian university students. Factor analysis of the DFS revealed three factors essentially identical to those found among university students in the US and in Singapore, as well as among US adult dental patients. Higher DFS scores were significantly associated longer intervals since last dental visit. These results are taken as evidence that the DFS performs in this Brazilian sample very much as it does in other samples; and is thus, a valid indicator of dental fear at least among Brazilian university students.
牙科恐惧调查问卷（DFS）是一种用于评估牙科恐惧和回避情况的纸笔式工具，在美国的恐惧研究中已被广泛使用并得到验证。然而，在将此类工具应用于与其开发地不同的国家和文化之前，应在该文化中进行交叉验证。本研究对374名巴西大学生群体中DFS的反应特征进行了考察。对DFS的因子分析显示，有三个因子与在美国、新加坡的大学生以及美国成年牙科患者中发现的因子基本相同。DFS得分较高与距上次看牙的间隔时间较长显著相关。这些结果被视为DFS在这个巴西样本中的表现与在其他样本中非常相似的证据；因此，至少在巴西大学生中，它是牙科恐惧的有效指标。
