The primary purpose of this article is to elaborate on a psychological concept related to Tinto's construct of social integration. The concept introduced in this article is worldview fit, defined as the perceived ideological compatibility between the student and the institution (e.g., faculty, peers). This purpose was accomplished through three research objectives: (a) construction of a worldview fit measure and an assessment of its psychometric properties, (b) examination of worldview fit across demographic groups at a religiously affiliated campus that might show worldview fit differences, and (c) testing the ability of the worldview fit measure to predict fall-to-fall retention in first-year students at a religiously affiliated campus. Results of this current study suggest that worldview factors might contribute to student satisfaction and retention. (Contains 2 tables.)
