Does the self-esteem or relationship quality of those dating outside their
ethnic group differ from those in a same-ethnic relationship? This study ad
dresses this question, assessing personal (e.g., self-esteem and clarity) a
nd relationship characteristics (commitment, satisfaction, realistic expect
ations, the level to which expectations were met, and partner preferences)
with an emphasis on ethnic identity. We studied 131 undergraduates, 58 in s
ame-ethnic heterosexual relationships (SERs) and 73 from mixed-ethnic heter
osexual relationships (MERs), Counter to the assumptions of many lay people
and scientists, we found no differences between the two groups. Ethnic ide
ntity was more predictive of relationship quality and commitment than was r
elationship composition (same versus mixed-ethnic). Furthermore, commitment
was significantly associated with the extent to which expectations were me
t for members of MERs, but not for those in SERs. Results are discussed in
the context of social psychological theories of group biases, impression fo
rmation, and prejudice, and consequences for the welfare of mixed-ethnic co
uples.
