This study tested Berzsonky's theory of identity styles and identity commitment in predicting religiosity. Participants were university students (N = 320) from Chile who were surveyed with the ISI-3 and BRS-6 instruments to measure identity styles and religiosity. Path analysis was used to test the model, which suggested that the three identity styles all had direct effects on commitment. Commitment, in turn, had a direct effect on religiosity. Results revealed that normative, informational, and diffuse-avoidant styles had direct effects on identity commitment, with commitment having a direct effect on religiosity. Also, normative style was shown to have a direct effect on religiosity. Overall, results indicated that commitment is key in explaining religiosity from the perspective of Berzonsky's theory.
