Assessment of Intrinsic Religiosity with a Single-Item Measure in a Sample of Arab Muslims

The objective of the current investigation was to examine the test–retest reliability and concurrent and factorial validity of a single-item measure to assess self-reported religiosity in an Arab-Muslim population. The sample was comprised of 531 volunteer Kuwaiti Muslim undergraduate men (n = 227) and women (n = 304). Participants responded to the one-item Self-Rating of Religiosity (SRR), the Self-Rating of Strength of Religious Belief (SRSRB), and the Hoge scale of Intrinsic Religious Motivation (IRM; 1972 Hoge, D. R. 1972. A validated intrinsic religious motivation scale. Journal for the Scientific Study of Religion, 11: 369–376. [Crossref], [Web of Science ®] , [Google Scholar]). The SRR had good temporal stability (0.89), and correlated with the SRSRB and IRM (0.577 and 0.498, respectively). One salient factor was extracted in which the SRR had a high loading (0.84). The study concluded that, despite its limitations, assessing religiosity with a single-item measure can be reliable, valid, and viable in community surveys.
