Iranians responded to Quest and Extrinsic Religious Orientation Scales in order to assess their validity and factor structure within a Muslim context. A sample of 251 Iranian university students received Persian versions of these instruments along with Intrinsic Religious Orientation, Interpersonal Reactivity, Constructive inking, Need for Cognition, and Openness to Experience Scales. Analysis of these data revealed that the Quest Scale contained four factors and validly measured Iranian religious commitments. Extrinsic and Intrinsic Religious Orientation Scales also clarified the psychological implications of religion in Iran. Extrinsic factors corresponded to American data; and as in previous Pakistani studies, Extrinsic-Personal scores were higher on average than those for the Intrinsic Orientation, which in turn was higher than the Extrinsic-Social motivation. These findings confirmed that the Quest and Intrinsic Scales along with the Extrinsic factors may be useful in the construction of a Muslim psychology of religion.
