项目摘要

DESCRIPTION (provided by applicant): Avoidance of regular dental care due to anxiety causes many in the United States to seek dental treatment only when in pain. This symptom-driven treatment reinforces the fear and avoidance of dentistry and leads to a worsening of overall oral and general health. An exciting new psychological approach has been developed to reduce fear, based on the well-established observation that anxious individuals process information about feared stimuli differently from non-anxious individuals. A type of Cognitive Bias Modification (CBM) has been developed to modify the attentional bias of anxious individuals so that they learn to direct their attention away from emotionally negative/threatening stimuli, resulting in a meaningful reduction in anxiety. Building on pilot work by our group, this application has 2 specific aims that are the critical next steps in the development of a CBM therapeutic intervention to reduce dental anxiety. The primary goal of Specific Aim 1 is to determine whether individuals who have a strong attentional bias toward threatening dental words are more fearful than those without an attentional bias. In addition, a battery of anxiety and dental fear survey items will be used to create a brief screening tool to predict which individuals have the greatest attentional bias. The goal of Specific Aim 2 is to use a separate sample to validate the ability of the screening tool to predict attentional bias using a refined attentional task based on the results of Specific Aim 1. In both studies, attentional bias will be assessed using a dot-probe attentional bias task, hosted by Project Implicit(R). In this task, the "threatening dental" / "non- dental, non-threatening" word pairs are presented briefly on a computer screen, vertically with one word above the other. When the words disappear, a probe immediately replaces either the dental or non-dental word and subjects are asked to rapidly identify the probe using a specific keystroke. Prior research has shown that compared to non-anxious individuals, those with anxiety respond more quickly when identifying a probe that appears in the location of the fear-related threatening word and more slowly when the probe replaces the neutral word. The threat bias index (TBI) provides a measure of an individual's attentional bias and will be calculated by subtracting the median response times for probes presented in place of the dental threat-related words from the median response times for probes presented in place of the neutral control words. The results obtained from these 2 specific aims will provide pilot data for an NIH application for a clinical investigation to test a CBM treatment battery for dental anxiety.
描述(由申请人提供):由于焦虑而避免定期牙科护理,导致美国许多人只有在疼痛时才寻求牙科治疗。这种由牙科医生驱动的治疗加强了对牙科的恐惧和回避,并导致整体口腔和一般健康状况的恶化。一个令人兴奋的新的心理学方法已经开发出来,以减少恐惧,基于既定的观察,焦虑的个人处理信息的恐惧刺激不同于非焦虑的个人。一种认知偏差修正(CBM)已经被开发出来,以修正焦虑个体的注意偏差,使他们学会将注意力从情绪上的负面/威胁转移开。 刺激,从而显着减少焦虑。基于我们小组的试点工作,该应用程序有2个具体目标,这是CBM治疗干预发展的关键下一步,以减少牙科焦虑症。具体目标1的主要目标是确定对威胁性牙科词汇具有强烈注意力偏见的个体是否比没有注意力偏见的个体更害怕。此外,一组焦虑和牙科恐惧调查项目将被用来创建一个简短的筛选工具,以预测哪些人有最大的注意力偏差。具体目标2的目标是使用一个单独的样本来验证筛选工具的能力,以预测注意力偏差使用一个细化的注意力任务的基础上的具体目标1的结果。在这两项研究中,注意力偏差将使用点探测注意力偏差任务进行评估,该任务由Project Implicit(R)主持。在这项任务中,“威胁性牙齿”/“非牙齿,非威胁性”的单词对被简要地呈现在计算机屏幕上,垂直地一个单词在另一个上面。当单词消失时,探针立即替换牙齿或非牙齿单词,并要求受试者使用特定的标记快速识别探针。先前的研究表明,与非焦虑个体相比,焦虑个体在识别出现在与恐惧相关的威胁词位置的探针时反应更快,而当探针取代中性词时反应更慢。威胁偏差指数(TBI)提供了一个测量个体的注意力偏差,并将通过从替代中性对照词的探针的中位响应时间中减去替代牙齿威胁相关词的探针的中位响应时间来计算。从这两个具体目标中获得的结果将为NIH申请临床研究提供试点数据,以测试CBM治疗 牙科焦虑症的治疗方法
