abstract
CONTEXT: Unmet spiritual needs have been associated with decreased patient ratings of quality of care, satisfaction, and quality of life. There is a need for a well-validated, psychometrically sound instrument to describe and measure spiritual needs. OBJECTIVES: To develop a valid and reliable instrument to assess patients' spiritual needs. METHODS: Instrument development was based on a literature review, clinical and pastoral evaluation, and cognitive pretesting (n=15 ambulatory cancer patients). Forty-seven ambulatory cancer patients completed cross-sectional and longitudinal surveys to test instrument validity and reliability. Internal reliability was assessed by Cronbach's α, test-retest reliability by Spearman's correlation coefficients, and construct validity by comparing instrument scores to a previously used single-item spiritual needs question. RESULTS: The Spiritual Needs Assessment for Patients (SNAP) comprises a total of 23 items in three domains: psychosocial (n=5), spiritual (n=13), and religious (n=5). Sixty percent of participants were white, 21% black, 13% Hispanic, and 6% Asian or other. Fifty-eight percent were Catholic, 13% Jewish, 11% Protestant, 2% Buddhist, 2% Muslim, and 2% Hindu. Sixty-eight percent described themselves as spiritual but not religious; 15% reported unmet spiritual needs; 19% wanted help meeting their spiritual needs. Cronbach's α for the total SNAP was 0.95, and for the subscales was psychosocial=0.74, spiritual=0.93, and religious needs=0.86. Test-retest correlation coefficients were total SNAP=0.69, psychosocial needs=0.51, spiritual needs=0.70, and religious needs=0.65. Participants reporting unmet spiritual needs had significantly higher mean scores on the total SNAP (66.3 vs. 49.4, P=0.03) and on the spiritual needs subscale (39.0 vs. 28.3, P=0.02). CONCLUSION: The results provide preliminary evidence that the SNAP is a valid and reliable instrument for measuring spiritual needs in a diverse patient population.
