Background
Health related quality of life (HRQOL) measures are common in oncology research, trials and practice. Spiritual well-being has emerged as an important aspect of HRQOL and the Functional Assessment of Chronic Illness Therapy Spiritual Well-Being; The 12-item Spiritual Well-Being Scale (FACIT-Sp-12) is the most widely used measure of spiritual well-being among those with cancer. However, there is an absence of reference values to facilitate the interpretation of scores in research and clinical practice. The objective of this study is to provide FACIT-Sp-12 reference values from a representative sample of adult cancer survivors.
Methods
As part of the American Cancer Society's Study of Cancer Survivors-II, a national, cross-sectional study of cancer survivors (N=8,864) completed questionnaires assessing demographic characteristics, clinical information, and the FACIT-Sp-12. Scores were calculated and summarized by FACIT-Sp-12 subscale and total scores across age, sex, race/ethnicity, time post-treatment, and cancer type.
Results
Independent samples T-test found that women reported significantly higher FACIT-Sp-12 scores (P<001). Analyses of variance found significant main effects for FACIT-Sp-12 scores by age (P<.01), race/ethnicity (P<.05), and cancer type (P<.001). Post-hoc comparisons revealed that older adults (60-69 and 70-79 year olds) and Black Non-Hispanics reported the highest FACIT-Sp-12 scores relative to 18-39 year olds (P<.05, d=0.20-0.50) and White Non-Hispanics (P<.05, d=0.02-0.62), respectively. All other significant main effects were small in magnitude (effect size range: 0.001-0.032).
Conclusion
These data will aid interpretation of the magnitude and meaning of FACIT-Sp-12 scores, and allow for comparisons of scores across studies.
