With few exceptions, existing research on attitudes toward genetic testing
and prenatal diagnosis is based on small studies using nonprobability sampl
es of specialized populations. In this paper we use a nationally representa
tive sample from the General Social Survey to report on attitudinal change
between 1990 and 1996, and to explore socio-demographic predictors of publi
c views on genetic technology and reproduction in the context of changing m
ass media coverage between 1988 and 1995. During that period, media coverag
e of prenatal testing became both less frequent and less favorable, despite
increasing use of this technology, whereas media reports about other types
of genetic testing increased in frequency and became more favorable. Betwe
en 1990 and 1996, attitudes toward genetic testing remained stable, althoug
h the attitudes of specific demographic subgroups may be changing in differ
ent directions. Attitudes toward abortion in case of genetic defect became
more negative over the period studied. We explore some of the implications
of these findings.
