This study examined the influence of different levels of feedback and of other situational and buffering variables on the psychological effects of ultrasound examinations of 211 pregnant women. The patients were randomly assigned to two different experimental conditions: high feedback and low feedback. The subjects' levels of anxiety (both trait- and state-anxiety) were measured immediately before and after the ultrasound examination. Overall, there was a significant decrease in the level of state-anxiety, which could not be explained by the different levels of feedback provided. Situational and buffering variables were not found to be related to the degree of psychological benefit produced by the scan.
本研究考察了不同反馈水平以及其他情境和缓冲变量对211名孕妇超声检查心理效应的影响。患者被随机分配到两种不同的实验条件下：高反馈和低反馈。在超声检查前后立即测量受试者的焦虑水平（特质焦虑和状态焦虑）。总体而言，状态焦虑水平有显著下降，这无法用所提供的不同反馈水平来解释。未发现情境和缓冲变量与扫描产生的心理益处程度相关。
