The Relationship Between Moral Thought-Action Fusion And Scrupulosity Across Judaism, Christianity, And Islam, Kelsey Evey Jan 2024

The Relationship Between Moral Thought-Action Fusion And Scrupulosity Across Judaism, Christianity, And Islam, Kelsey Evey

Graduate Theses, Dissertations, and Problem Reports (ETD)

Scrupulosity is a subtype of obsessive-compulsive disorder (OCD) where individuals are upset by intrusive thoughts related to religious or moral issues. Current research suggests that scrupulosity occurs across the major world religions—including the Abrahamic religions (i.e., Judaism, Christianity, and Islam). Some research suggests that moral thought-action fusion (moral TAF), a dysfunctional belief that thinking something is equal to doing it, may only be pathological under certain circumstances (e.g., if it is not culturally normative). If this is true, the current cognitive model of scrupulosity may need to be amended to reflect how cultural differences impact the role of moral TAF …
