In spite of scientific developments, paranormal beliefs remain widespread, especially in South Asian societies. Numerous disorders connected to possession and trance have been theorized in recent years. In this study, three community samples were used to develop a comprehensive scale of Belief in Jinn Possession Scale (BJPS) and to examine its consistency and relevance. The BJPS scale was proposed to be multidimensional with four factors displaying satisfactory internal consistency reliability estimated by the exploratory factor analysis (EFA) ( n = 300). (...) However, confirmatory factor analyses ( n = 300) reduced the number of factors to two. The BJPS demonstrated excellent reliability and statistically significant positive correlations among its factors of beliefs about signs of possession and beliefs about vulnerability and preventive measures. Convergent and discriminant validity ( n = 316) was supported by a high correlation between BJPS, Revised Paranormal Belief Scale (RPBS), and Paranormal and Supernatural Belief Scale (PSBS) and a low correlation between BJPS, Narcissistic Personality Inventory 16 (NPI-16), and Moral Identity Measure (MIM). These results suggest that the BJPS is a well-grounded and sound tool for evaluating one’s irrational beliefs about possession states in Pakistani culture, and it may be the first attempt to conceptualize possession.
