Prenatal diagnosis of fetal disorders. Part II: Issues and implications

Patterns of mood states in pregnant women undergoing chorionic villus sampling or amniocentesis

The purpose of this study was to compare patterns of self-reported mood states of women having chorionic villus sampling (CVS) (n = 151) to those of women electing amniocentesis (n = 30) with the indication of advanced maternal age. Mood states were defined as scores on the 6 subscales of the Profile of Mood States (POMS). Women at 4 U.S. prenatal diagnostic facilities completed the POMS at 4 assessment periods. These were a) at their initial genetic counseling session, b) 2 weeks post CVS results (or an equivalent time), c) 2 weeks post amniocentesis results (or an equivalent time), and d) at 30 weeks gestation. Repeated measures analysis of variance revealed that anxiety, fatigue, and confusion decreased, and vigor increased in both groups as the pregnancy progressed. Depression decreased in both groups and then increased at assessment 4 in women in the amniocentesis group but not in those electing CVS. Results should be interpreted in conjunction with obstetrically and genetically-oriented findings regarding safety and accuracy to help women decide between the 2 procedures.
