Abstract Title of Dissertation: A LONGITUDINAL STUDY OF PERSON CULTURE FIT: CONVERGENCE OF MENTAL MODELS

The person-environment fit hypothesis argues that the match or fit between an individual and the environment predicts positive adaptation outcomes for the person. Unfortunately, the person-environment fit hypothesis has not received consistent empirical support in the context of cross-cultural adaptation due to lack of a clear conceptualization of fit and an appropriate measure of fit. This dissertation proposes to use the convergence of mental models, a dynamic constructivist approach, to conceptualize person-culture fit, and to use it as a viable mechanism for understanding cross-cultural adaptation processes. A cross-lagged structural equation model was developed to examine how cultural adaptability and host language proficiency lead to positive adaptation outcomes through the mediating roles of mental model convergence and mental model change. Participants were 126 sojourning Chinese students studying in the U.S. and 30 American students and professors who were friends of the Chinese participants. Data were collected from the Chinese participants at two points in time: shortly after they arrived in the U.S. and three months after the first round of data collection. Based o
