This document presents a review of the literature on the social interaction of sojourning college students with host nationals and with conationals (fellow sojourners from the same culture). Research is reviewed which explores the possibility that deleterious effects of separation are partially offset by social interaction with host nationals. A brief overview of the separation literature is included. The literature relevant to student sojourners is focused on five areas involving the effects of social interaction with host nationals: sojourner attitudes, alienation, language acquisition, national origin, and the sojourner interaction with fellow conationals. The results of the review conclude that: (1) sojourner attitudes that correlated positively with increased social interaction and adjustment included world-mindedness, interpersonal relatedness, respect, favorable attitudes toward the host culture, assertiveness, self-assurance, and motivation to sojourn for social or cultural reasons; (2) social contact with host nationals correlated negatively with alienation; (3) proficiency in the host language enhanced social interaction between sojourners and host nationals and was positively correlated with adjustment; (4) cultural distance was correlated negatively with social interaction and adjustment, and sojourners coming from countries similar to the host culture reported better adjustment and greater satisfaction with their sojourn; and (5) sojourners whose primary social interaction was with conationals were less well-adjusted in comparison to those who had greater levels of interaction with host nationals. Methodological considerations are addressed; implications for facilitating sojourner adjustment are discussed. (NB)
