The present study investigated whether discrepancies between retrospectively recalled pre-migration expectations and post-migration experiences on the basis of expectancy violation theory (EVT) would be a strong predictor of acculturative stress. The sample consisted of random Hispanic international students (N = 77) across different regions in the United States. Acculturative stress was measured using the Acculturative Stress Scale of International Students (ASSIS). Results confirmed that discrepancies between pre-migration expectations and postmigration experiences resulted in acculturative stress in this population even when accounting for general demographic variables. Furthermore, this study found that when post-migration experiences fall below pre-migration expectations there is an increase in acculturative stress and when post-migration experiences exceed or are perceived as positive in relation to the pre-migration expectations less acculturative stress is reported. The findings in this study suggest that pre-migratory expectations influence acculturative stress. Demographic analyses within this study also reveal that variables such as age, socio-economic status, and living with others also impact levels of acculturative stress among Hispanic international students. Implications for culturally adaptive interventions at the institutional and provider level, as well as research opportunities with EVT in the Hispanic and international student population are discussed.
