Trajectories of spiritual well-being in long-term survivors of cancer: A report from the American Cancer Society's studies of Cancer Survivors-I.

BACKGROUND: Existing research indicates that religion, spirituality, or both are important to the quality of life of patients with cancer. The current study is the first to characterize trajectories of spiritual well-being (SWB) over time and to identify their predictors in a large, diverse sample of long-term cancer survivors.

METHODS: The participants were 2365 cancer survivors representing 10 cancer diagnoses from the American Cancer Society's Studies of Cancer Survivors-I, and they were assessed at 3 time points: 1, 2, and 9 years after their diagnosis. SWB was assessed with the 3 subscales of the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being (FACIT-Sp; ie, Meaning, Peace, and Faith). Predictors included demographic, medical, and psychosocial variables. Latent growth mixture modeling was used to identify trajectories and test their predictors.

RESULTS: Four distinct trajectories of SWB were identified for each of the FACIT-Sp subscales: stable-high (45%-61% of the sample, depending on the subscale), stable-moderate (23%-33%), stable-low (7%-16%), and declining (6%-10%). Significant predictors of these trajectories included age, sex, race, education, comorbidities, symptom burden, social support, and optimism, but not always in the hypothesized direction. For some of the subscale trajectories, a recurrence of cancer, multiple cancers, or metastatic cancer was associated with lower SWB.

CONCLUSIONS: This is the first study to establish the existence and predictors of heterogeneous trajectories of SWB in long-term survivors of cancer. Because SWB is an important component of quality of life, the current results indicate characteristics of persons who could be at greater risk for a decline or consistently low scores in SWB and may warrant clinical attention.
