The present study assesses the relationship between self-reported dental anxiety (Dental Anxiety Inventory, Dental Anxiety Scale, and Duration of Psychophysiological Fear Reactions), electrodermal activity (skin-conductance level and frequency of spontaneous responses), and Marlowe-Crowne defensiveness. All measurements were made twice. The first session was scheduled immediately before a semi-annual dental check-up (stress condition), and baseline measurements were made two months later without the prospect of a dental appointment. Subjects were male dental patients who regularly attended a university dental clinic and a clinic for Special Dental Care. The main findings were that the low anxious-high defensive-scoring (Marlowe-Crowne Denial subscale) university patients showed significantly higher skin-conductance levels and frequency of nonspecific fluctuations than the low anxious-low defensive-scoring subjects. Besides, the conductance values of the low anxious-high defensive-scoring subjects resembled those of the high anxious-low defensive-scoring patients of the clinic for Special Dental Care, the baseline frequency of nonspecific fluctuations excepted.
本研究评估了自我报告的牙科焦虑（牙科焦虑量表、牙科焦虑问卷以及心理生理恐惧反应的持续时间）、皮肤电活动（皮肤电导水平和自发反应频率）与马氏社会赞许性防御之间的关系。所有测量均进行了两次。第一次测量安排在半年一次的牙科检查前（应激状态），两个月后在没有牙科预约预期的情况下进行基线测量。受试者为定期前往大学牙科诊所和特殊牙科护理诊所就诊的男性牙科患者。主要研究结果表明，低焦虑-高防御得分（马氏社会赞许性否认分量表）的大学患者相比低焦虑-低防御得分的受试者，皮肤电导水平和非特异性波动频率显著更高。此外，低焦虑-高防御得分受试者的电导值与特殊牙科护理诊所高焦虑-低防御得分患者的电导值相似，但非特异性波动的基线频率除外。
