The present article aims to design and validate a scale for measuring self-deception based on Islamic teachings. In the concept extraction stage, descriptive method and analysis of Islamic sources were used. Psychometric evaluation was conducted with the participation of 240 university students of the Velayat project. Face and content validity were assessed by experts and using CVI and CVR indices. The initial version included 115 items, which were reduced to 85 items after validity analysis. The validity of the scale was confirmed in the pilot and final stages with Cronbach's alpha coefficient (0.865 and 0.813), Spearman-Brown split-half coefficients (0.901 and 0.856), and Guttman coefficients (0.893 and 0.842). The correlation coefficient between the two halves was also high in both stages (0.815 and 0.796, respectively), indicating acceptable internal consistency. The final scale is a native instrument that is consistent with Islamic principles and includes the five main components of ignorance, desire for pleasures, individual deviation, egotism, and secrecy. The findings show that this instrument has desirable validity and reliability and can be used in personality psychology research, Islamic studies, and clinical interventions.
