Measuring spirituality as a universal human experience: development of the Spiritual Attitude and Involvement List (SAIL)

Abstract

Many cancer patients experience spirituality as highly supportive while coping with their disease. Most research as well as most questionnaires in this field is religious orientated. The Spiritual Attitude and Involvement List was developed to enable research on spirituality among religious and nonreligious people. It consists of seven subscales that measure connectedness with oneself, with others and nature, and with the transcendent. Among a student, a healthy population, a healthy interested, a curative cancer, and a palliative cancer sample factorial, convergent and discriminant validity were demonstrated, as well as adequate internal consistency and test-retest reliability.
