Multi-Dimensional Fundamentalism Inventory (MDFI)
The Multi-Dimensional Fundamentalism Inventory (MDFI) is a 15-item questionnaire capturing the extent of religious fundamentalism. The instrument consists of three subscales of five items each: External/Internal authority, Fixed/Malleable religion, and Rejection/Affirmation of the world. The first dimension captures the belief that an individual’s actions are moral and right only if they are based on God’s authority. The second dimension represents the attitude that religious tradition is a given and exists independently of historical and cultural conditions. The third dimension captures the valuing of the sacred over secular experiences.
Length of completion
The MDFI takes approximately 5 minutes to complete.
