FACIT-Sp

The Functional Assessment of Chronic Illness Therapy – Spiritual Well-Being (FACIT-Sp) is a 12-item self-report measure assessing spiritual well-being in people with chronic and life-threatening illnesses. It comprises three subscales: Meaning (4 items, sense of purpose and productiveness), Peace (4 items, sense of harmony and inner peace), and Faith (4 items, relationship between illness and spiritual beliefs). Each item is rated 0–4, with total scores from 0 to 48. The FACIT-Sp was a primary or co-primary endpoint in the landmark psilocybin trials for cancer-related psychological distress at Johns Hopkins (Griffiths et al., 2016) and NYU (Ross et al., 2016), where single-dose psilocybin produced large, sustained increases in spiritual well-being. It captures a dimension of therapeutic change that symptom-focused measures miss — the existential and spiritual transformation frequently reported by participants in psychedelic-assisted therapy.
