We are presenting a unique approach to understanding couples and relat
ionships based on social constructionist principles. It is our belief
that individuals possess constructions of reality with regard to relat
ionships and must co-create a reality in which both partners participa
te. The implication of this theoretical principle is that differences
between partners are not as important as the negotiation of such diffe
rences. One thousand premarital couples were examined to determine the
effect of levels of flexibility and perceived differences on the qual
ity of their relationships. Data analysis revealed that levels of flex
ibility were a significant factor in couples' abilities to co-create a
successful shared reality.
