The purpose of this study was to determine if anxiety can be measured objectively by skin conductance of a weak electric current. Three measurements were taken. First, a standardized dental-anxiety questionnaire was given to determine anxiety. Second, galvanic skin conductance was measured. Third, polygraph responses were recorded to three key questions from the questionnaire. Questionnaire scores of these key questions were used to create two groups: anxious and not-anxious. The three key questions were subjected to polygraph verification. In the first analysis patients were excluded if the polygraph test disclosed lying on any of the three key questions. The second analysis excluded liars on a question-by-question basis. The third analysis disregarded the polygraph. A statistically significant correlation was found between skin conductance and dental anxiety in all cases. Data seem to indicate that fear of injection is the most anxiety-producing aspect of modern dentistry.
本研究的目的是确定焦虑是否可以通过弱电流的皮肤电导率进行客观测量。进行了三项测量。首先，发放一份标准化的牙科焦虑问卷以确定焦虑程度。其次，测量皮肤电导率。第三，记录对问卷中三个关键问题的测谎仪反应。这些关键问题的问卷得分被用于创建两组：焦虑组和非焦虑组。对这三个关键问题进行了测谎仪验证。在第一次分析中，如果测谎仪测试显示在任何一个关键问题上说谎，则将患者排除。第二次分析逐题排除说谎者。第三次分析则忽略测谎仪结果。在所有情况下，均发现皮肤电导率与牙科焦虑之间存在统计学上的显著相关性。数据似乎表明，对注射的恐惧是现代牙科中最易引发焦虑的方面。
