This study examines women's psychological responses to prenatal group genetic counseling, and to subsequent individualized risk counseling. All women (N=123) aged 35 and older underwent nuchal translucency screening (NTS), a prenatal ultrasound screening test. After group counseling, decisional conflict decreased significantly among those reporting at baseline having made a decision about invasive testing (t(222)=2.0, P=0.014) and for those who were uncertain (t(222)=5.74, P <0.0005). After receiving NT-adjusted risks, decisional conflict decreased further for those uncertain about testing at baseline (t(222)=4.64, P <0.0005). There was no change in risk perception and anxiety after group counseling. After NT-adjusted risks were communicated, risk perception decreased significantly (t(230)=5.02, P <0.0005), as did anxiety (t(115)=7.91, P <0.005). Despite reassuring NTS results, the uptake rate for prenatal invasive testing was 78.4%. Risk perception, anxiety, and decisional conflict decreased after individual counseling for reassuring NTS results, but the uptake of invasive testing remained high.
