The effects of ultrasound examination on maternal anxiety levels. The effect of the amount of feedback on anxiety levels during ultrasound scanning. Impact of fetal testing on maternal anxiety.
A study has been conducted to assess the psychological effects of real-time ultrasound on the pregnant woman's attitudes and anxiety levels. A consecutive series of primiparae, fulfilling the selection criteria of obstetrically "low risk," was assigned at random to two conditions of ultrasound, namely, (a) high feedback (N = 67), where the woman saw the moving fetus in utero; and (b) low feedback (N = 62), where the monitor screen was not visible and no specific feedback was provided. A third group of women was assessed following a wait period in order to compare state anxiety levels among the three groups. Attitude assessments showed consistent preultrasound-post-ultrasound change, with more uniformly positive attitudes displayed by the high-feedback group. No between-group differences in state anxiety emerged as a result of ultrasound compared with a wait control period. No differences emerged with respect to anticipatory anxiety measures. The results are considered in the context of evidence on the importance of psychological state on the course and outcome of pregnancy. It is suggested that the low-risk characteristics of this sample may have precluded effects on anxiety and it is concluded that the therapeutic potential of ultrasound warrants further study. 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. We evaluated the impact of fetal testing on maternal anxiety. A consecutive series of high-risk women attending during the third trimester for fetal assessment were each randomly assigned to one of four conditions: (1) high-feedback ultrasonography (n = 11), in which the monitor screen was visible; (2) low-feedback ultrasonography (n = 8), in which specific visual and verbal feedback was denied; (3) fetal heart rate monitoring (n = 11); or (4) a video control (n = 7), in which the women viewed a videotape of an ultrasonographic recording. Assessments were conducted before and after each procedure. No change was found in attitude ratings towards the fetus, although there was a significant reduction in state anxiety from before to after, with the reduction most pronounced in women undergoing high-feedback ultrasonography.
There is insufficient evidence to support either high or low feedback during a prenatal ultrasound to reduce maternal anxiety and promote health behaviour.
