cross-cultural adaptation
Definition
Cross-cultural adaptation refers to the psychological and socio-cultural outcomes associated with migrants' and ethnic minority members' engagement with their heritage culture and the mainstream culture of their receiving society. Research in this area has long proceeded on the assumption that engaging with both cultures simultaneously, the integration strategy, produces better adaptation outcomes than engagement with only one culture or neither. Meta-analytical evidence challenges this assumption directly: when interaction effects are tested using a multivariate approach that controls for main effects, the variance explained tends toward zero, with the positive adaptation outcomes previously attributed to integration shown instead to be driven by the main effect of mainstream-culture orientation. Factors such as perceived discrimination and connectedness show stronger associations with adaptation than cultural orientation variables, pointing to the need to examine predictors beyond acculturation strategies.

Cross-cultural Adaptation and Integration Hypothesis
The integration hypothesis predicts that high engagement with both mainstream and heritage cultures produces better adaptation outcomes than engagement with either culture alone, making integration an interaction effect by definition. Meta-analytical tests using bivariate approximations, including summative, multiplicative, Euclidean distance, and midpoint split approaches, consistently produced inflated positive correlations ranging from approximately .06 to .23, but a multivariate test using meta-analytical structural equation modelling yielded a near-zero, non-significant interaction effect. In the ICSEY dataset the interaction term was statistically significant but negative, with mainstream orientation showing a stronger benefit when heritage orientation was low, directly contradicting the hypothesis.

Cross-cultural Adaptation and Mainstream Culture Orientation
Mainstream culture orientation is a more consistent correlate of positive adaptation outcomes than heritage culture orientation or integration as a combined construct. Meta-analytical results show that a model using mainstream orientation alone explains roughly as much variance in adaptation as a model including both cultural orientations and their interaction term. The positive adaptation effects previously reported as evidence for integration can therefore be attributed to the main effect of mainstream orientation, while the heterogeneity in those effects is attributable to heritage culture orientation, which produces associations with adaptation that are sometimes positive and sometimes negative.
