目的：我们研究了症状解释框架对内感准确性的影响，以及对医学上无法解释的症状的非临床高、低报告者的回溯性症状报告的作用。方法：所有参与者(N=74)随后都接受了两次重复呼吸测试，由于血液中PCO(2)水平的逐渐升高，导致呼吸和其他身体感觉改变。每个试验包括基线(60名S)、复呼吸期(150名S)和恢复期(150名S)。在一项试验中，这些感觉是以一种中性的方式构成的(“气体混合物可能会改变呼吸行为并引发呼吸感觉”)。在另一项试验中，诱导出一个症状框架(“气体混合物可能会改变呼吸行为并引发呼吸道症状”)。持续监测呼吸行为，每10次对S的主观感觉进行评分，每次试验后，参与者填写症状检查表。对于每个试验的再呼吸期和恢复期，分别计算主观评分与其生理参照物之间的受试者内相关性。结果：高症状记者的投诉(回溯性)多于低症状记者，尤其是在症状试验中。只有在症状框中，高症状记者的准确性低于低症状记者。在症状框架试验的恢复阶段，高症状报告者的感觉间准确性(IA)的下降最为显著。结论：背景线索，如参考症状，减少了高症状记者的IA，在从症状诱导中恢复的过程中更是如此。(C)2008 Elsevier Inc.保留所有权利。
Objective: We investigated the role of a symptom interpretation frame on the accuracy of interoception and on retrospective symptom reporting in nonclinical high and low reporters of medically unexplained symptoms. Methods: All participants (N=74) went through two subsequent trials of the Rebreathing Test, inducing altered respiration and other physical sensations as a result of a gradually increasing pCO(2) level in the blood. Each trial consisted of a baseline (60 s), a rebreathing phase (150 s), and a recovery phase (150 s). In one trial, the sensations were framed in a neutral way ("the gas mixture might alter breathing behavior and induce respiratory sensations"). In the other trial, a symptom frame was induced ("the gas mixture might alter breathing behavior and induce respiratory symptoms"). Breathing behavior was continuously monitored, subjective sensations were rated every 10 s, and after each trial, participants filled out a symptom checklist. Within-subject correlations between the subjective rating and its physiological referent were calculated for the rebreathing phase and recovery phase of each trial separately. Results: High symptom reporters had more (retrospective) complaints than low symptom reporters, especially in the symptom trial. Only in the symptom frame were high symptom reporters less accurate than low symptom reporters. The reduction in interoceptive accuracy (IA) in high symptom reporters was most striking in the recovery phase of the symptom frame trial. Conclusion: A contextual cue, such as a reference to symptoms, reduced IA in high symptom reporters and this was more so during recovery from the symptom induction. (C) 2008 Elsevier Inc.
