This study explored the relationship between personality, cultural fit (similarity between sojourners and hosts), and psychological adjustment during cross-cultural transitions. One hundred and twenty four AFS student sojourners in New Zealand participated in the study and completed questionnaires which assessed extraversion, locus of control, allocentrism, tolerance of ambiguity, coping humour, and psychological adjustment. It was hypothesised that internal locus of control, tolerance of ambiguity and coping humour would be significantly related to psychological adjustment but that extraversion and allocentrism would be affected by cultural fit; i.e., a host-sojourner match. In addition to performing zero order correlations between personality variables and psychological adjustment, cultural fit was examined by relating discrepancies between sojourner personality and host culture norms (provided by a comparative sample of 146 New Zealand secondary students) to psychological adjustment. The results did not support the concept of culture fit. While personality discrepancies were unrelated to mood disturbance in AFS students, internal locus of control, coping humour, and extraversion were significantly linked to diminished mood disruption. Methodological and conceptual problems and avenues for further research are discussed.
