Exploring the double-edged sword of cultural variability in interactions with family versus friends

Cultural variability (CV) refers to the tendency to vary/adjust the influence of a single cultural identity on one’s social interactions and behaviors from day to day. CV has different influences on interpersonal interactions, positive for some interactions but with adverse effects for others; hence, we aimed to further explore these associations by considering immigrant status and ethnic orientation as potential moderators. Hierarchical regression using daily diary self-reports of U.S. emerging adults (N=242) revealed that cultural variability is a double-edged sword only for first- and second-generation immigrants rather than for nationals (3rd generation and later). That is, CV predicts positive family interactions for both groups, but negative interactions with close friends only for immigrants, especially those with strong ethnic orientation. Cultural variability adds a new dimension to our understanding of cultural identity as dynamic, domain-specific, and nuanced in its associations with adaptation.
