Table_1_A double-blind randomized clinical trial on the suggestive effect of anxiety management questionnaires in dental emergencies.DOC

ObjectiveDental anxiety is widespread among both children and adults. To diagnose dental anxiety, standardized anxiety questionnaires are recommended. Based on the suggestive nature of the questionnaires, the study aimed to find out whether asking respondents about personal coping strategies before dental treatment influences their anxiety.
MethodsThis prospective, double-blind, randomized controlled clinical trial included a total of 158 patients of a university dental clinic on emergency service. The intervention group (n = 82) received the Coping with Anxiety Questionnaire (CAQ) and the control group (n = 76) the Hierarchical Anxiety Questionnaire (HAF). State anxiety scores were assessed by using the State–Trait Anxiety Inventory (STAI) before and after the completion of each questionnaire.
ResultsAnxiety decreased in the intervention group (CAQ) (p < 0.001) and increased in the control group (HAF) (p < 0.001).
ConclusionWithin the limitations of the current study, a diagnostic tool of a standardized questionnaire for the assessment to assess personal coping strategies decreased state anxiety in comparison to a questionnaire assessing anxiety.

牙科焦虑在儿童与成人中均广泛流行。目前临床推荐采用标准化焦虑问卷进行牙科焦虑的诊断。鉴于现有问卷具有暗示性特征，本研究旨在探究在牙科治疗前询问受访者个人应对策略，是否会对其焦虑水平产生影响。
方法 本研究为一项前瞻性、双盲、随机对照临床试验，共纳入某大学牙科诊所急诊服务接诊的158名患者。干预组（n=82）填写《应对焦虑问卷（Coping with Anxiety Questionnaire, CAQ）》，对照组（n=76）填写《层级焦虑问卷（Hierarchical Anxiety Questionnaire, HAF）》。在每份问卷填写前后，均采用状态-特质焦虑量表（State–Trait Anxiety Inventory, STAI）评估状态焦虑得分。
结果 干预组（CAQ）的焦虑水平显著降低（p<0.001），对照组（HAF）的焦虑水平则显著升高（p<0.001）。
结论 在本研究的局限性范围内，相较于仅评估焦虑水平的问卷，用于评估个人应对策略的标准化诊断问卷可降低受试者的状态焦虑水平。
