Psychological impact of amniocentesis on low-risk women

The study comprised 85 young (25–34 years old) women who underwent genetic amniocentesis, 80 comparable young women who had an ultrasoundscan at the same gestational age and 74 women (35–40 years old) who had amniocentesis. The State-Trait Anxiety Inventory and Visual Analogue Scales concerning anxiety and worry were used on four occasions to evaluate psychological changes during pregnancy. The anxiety level in the younger women decreased after amniocentesis and a further decrease was observed after the results were communicated to them. However, similar changes were seen in the group of younger women after ultrasonography, and there was no difference in anxiety level between the two groups of younger women in the 16th or in the 35th week of pregnancy. Thus, in younger women at low genetic risk amniocentesis was neither anxiety-relieving, nor anxiety-creating. The level of anxiety before amniocentesis was not higher in the older than in the younger women having amniocentesis. However, in the younger women a significant decrease in anxiety was seen as soon as amniocentesis had been performed, while in the older women this decrease was delayed until after the results were known.
