This article proposes an extension of Janet Helms's Black and White in
teraction model to be used as a starting point for organizing and unde
rstanding cultural-identity data in making an initial family assessmen
t. A number of efforts to describe how culture affects family counseli
ng have focused on between-group differences. The interaction model pr
esented here endeavors to expand that discussion by systematically inc
luding (a) within-group cultural differences in families, (b) changes
in cultural-identity attitudes over time, (c) attention to the counsel
or's stage of cultural identity (in addition to those of the family's
various subsystems), and (d) consideration of cultural differences in
the work of counselors and families from the same culture or in the wo
rk of nondominant culture counselors working with dominant-culture fam
ilies. The article reviews the Helms model and other pertinent constru
cts from the literature, extends the theory to multicultural family co
unseling, and concludes with some illustrative cases suggesting how th
e interaction paradigm might be applied.
