Perceived versus Objective Cultural Distance: Differential Effects on Acculturation Experiences.

How do perceived and objective cultural distance compare in predicting immigrants' acculturation experiences? Using data from a diverse sample of immigrants residing in the United States (N = 939), we examined perceived cultural distance alongside objective cultural distance measured by the Cultural Fixation Index (CFST ), a novel and flexible metric derived from World Values Survey data that captures between-group variation in cultural values. Our findings reveal that perceived cultural distance, assessed using the Brief Perceived Cultural Distance Scale, was more often associated with psychological outcomes, including higher homesickness (β = .08) and lower psychological adaptation (β = -.08). In contrast, objective cultural distance was negatively associated with physical health (β = -.16), and stronger orientations toward host culture (β = .08). The two measures were moderately correlated (r = .34), and both predicted greater culture shock and stronger heritage culture orientation. Neither objective nor perceived cultural distance significantly predicted depressive symptoms or anxiety. These findings highlight the importance of assessing both subjective perceptions and objective measures of cultural differences when studying acculturation and considering their respective trade-offs.
