Research suggests that spiritual transformation, a change in the way a person considers the sacred, can change medical outcome (Pargament, 2006). Psychometric studies have failed to identify specific factors, but qualitative reports detail an experience that can be reliably shown to have an impact. We report on the development of a rubric for quantifying levels of spiritual transformation. Narrative analysis techniques were used to quantify levels of spiritual transformation from participants' life stories, experience with traditional healers, and subsequent medical status. A quantification rubric was developed and 111 assistants rated the stories after a three-hour training session. Inter-observer reliability was 0.87 (95% CI, 0.72 to 0.97, p less than 0.001). Findings suggest it is possible to develop reliable coding scenarios that independent raters can follow to use in research to quantifiably assess spiritual transformation. (Contains 1 footnote.)
