[Screening for Down's syndrome can cause both security and anxiety].

: Most women experience periods of increased anxiety and worry during pregnancy, and in many cases it is an appropriate response to a novel situation of change and transition. Women participate in screening for Down's syndrome in order to receive a general reassurance of the health of their baby. Generally, a screen-negative result does increase pregnant women's feelings of reassurance. A screen-positive result generates uncertainty and anxiety, however this anxiety declines to normal levels following a normal diagnostic result.
