The Religious and Spiritual Struggles Scale (Exline and colleagues, 2014) maps six kinds of tension that can surface in a faith or spiritual life: anger at or distance from the divine, troubling doubt, fear of evil or supernatural forces, moral guilt, conflict with others over religion, and questions of ultimate meaning. Common to devout believers, seekers and doubters alike, a struggle here marks a passage in someone's spiritual journey — not a verdict on how strong their faith is.
The Religious and Spiritual Struggles Scale (Exline, Pargament, Grubbs & Yali, 2014) is a validated measure of the tensions people experience in their faith life. These struggles are common among believers and seekers alike and don't imply weak faith. (Religious/Spiritual Struggles Scale (Exline et al.))
