In a two-wave survey study designed to extend and refine previous research on religion as an attachment process, college students completed a four-category attachment-style measure and several religiosity measures at Time 1; a subsample also completed identical religiosity measures about 4 months later (Time 2). Analysis of Time 1 data (N= 1,126) extended previous findings by demonstrating that positive mental models of both self and others were related cross-sectionally to positive images of God and perceived relationships with God. Longitudinal analyses (N = 297) revealed that positive religious change over time was predicted by negative models of self and positive models of others. Discussion focuses on the dynamics of religious belief and change as a function of psychological attachment processes.
