Abstract

OBJECTIVE

The 12-item Functional Assessment of Chronic Illness Therapy-Spiritual Well-being Scale (FACIT-Sp) is a popular measure of the religious/spiritual (R/S) components of quality of life (QoL) in patients with cancer. The original factor analyses of the FACIT-Sp supported two factors: Meaning/Peace and Faith. Because Meaning suggests a cognitive aspect of R/S and Peace an affective component, we hypothesized a 3-factor solution: Meaning, Peace, and Faith.

METHODS

Participants were 240 long-term female survivors of cancer who completed the FACIT-Sp, the SF-12, and the BSI 18. We used confirmatory factor analysis to compare the 2- and 3-factor models of the FACIT-Sp and subsequently assessed associations between the resulting solutions and QoL domains.

RESULTS

Survivors averaged 44 years of age and 10 years post-diagnosis. A 3-factor solution of the FACIT-Sp significantly improved the fit of the model to the data over the original 2-factor structure (Delta chi(2)=72.36, df=2, p<0.001). Further adjustments to the 3-factor model resulted in a final solution with even better goodness-of-fit indices (chi(2)=59.11, df=1, p=0.13, CFI=1.00, SMRM=0.05).The original Meaning/Peace factor controlling for Faith was associated with mental (r=0.63, p<0.000) and physical (r=0.22, p<0.01) health on the SF-12, and the original Faith factor controlling for Meaning/Peace was negatively associated with mental health (r=-0.15, p<0.05). The 3-factor model was more informative. Specifically, using partial correlations, the Peace factor was only related to mental health (r=0.53, p<0.001); Meaning was related to both physical (r=0.18, p<0.01) and mental (r=0.17, p<0.01) health; and Faith was negatively associated with mental health (r=-0.17, p<0.05).

CONCLUSION

The results of this study support a 3-factor solution of the FACIT-Sp. The new solution not only represents a psychometric improvement over the original, but also enables a more detailed examination of the contribution of different dimensions of R/S to QoL.

摘要

目的

慢性病治疗-精神健康状况量表（FACIT-Sp）的12项版本是一种常用的衡量癌症患者生活质量（QoL）宗教/精神（R/S）成分的工具。FACIT-Sp最初的因素分析支持两个因素：意义/安宁与信仰。由于意义暗示了R/S的认知方面，而安宁暗示了情感成分，我们假设存在一个三因素解决方案：意义、安宁和信仰。

方法

参与者为240名癌症长期女性幸存者，她们完成了FACIT-Sp、SF-12和BSI 18。我们使用验证性因素分析来比较FACIT-Sp的二因素模型和三因素模型，随后评估所得解决方案与生活质量领域之间的关联。

结果

幸存者的平均年龄为44岁，确诊后平均10年。FACIT-Sp的三因素解决方案比原来的二因素结构显著提高了模型对数据的拟合度（Δχ²=72.36，自由度=2，p<0.001）。对三因素模型的进一步调整产生了一个拟合优度指标更好的最终解决方案（χ²=59.11，自由度=1，p=0.13，CFI=1.00，SMRM=0.05）。在控制信仰的情况下，原来的意义/安宁因素与SF-12上的心理健康（r=0.63，p<0.000）和身体健康（r=0.22，p<0.01）相关，而在控制意义/安宁的情况下，原来的信仰因素与心理健康呈负相关（r=-0.15，p<0.05）。三因素模型提供了更多信息。具体而言，使用偏相关分析，安宁因素仅与心理健康相关（r=0.53，p<0.001）；意义与身体健康（r=0.18，p<0.01）和心理健康（r=0.17，p<0.01）均相关；信仰与心理健康呈负相关（r=-0.17，p<0.05）。
