Dimensions, determinants, and differences in the expatriate adjustment process

We comprehensively test the Black, Mendenhall, and Oddou (1991) model of the dimensions and determinants of adjustment to international assignments. We also expand the model to examine two individual factors (i.e., previous assignments and language fluency) and three positional factors (i.e., hierarchical level, functional area, and assignment vector) as moderators of adjustment determinants. Surveys were completed by 452 expatriates from 29 different countries assigned to 45 host countries by large multinational firms. The multi-dimensionality of adjustment was investigated and confirmed. Support for the expanded Black et al. (1991) model was found. Several significant moderating effects emerged, showing different patterns of adjustment for those with different amounts of pervious expatriate experience and levels of host country language fluency Hierarchical level and assignment vector were also important moderators, but the effects for functional area were generally weak.
