Spirituality moderates the relationship between cancer caregiver burden and depression.

ABSTRACT

OBJECTIVES: Cancer has become a chronic disease that requires a considerable amount of informal caregiving, often quite burdensome to family caregivers. However, the influence of spirituality on the caregivers' burden and mental health outcomes has been understudied. This study was to examine how caregiver burden, spirituality, and depression change during cancer treatment and investigate the moderating role of spirituality in the relationship between caregiver burden and depression for a sample of caregivers of persons with cancer. METHODS: This secondary analysis used a longitudinal design employing 3 waves of data collection (at baseline, 3 months, and 6 months). Family caregivers completed the Caregiver Reaction Assessment, Spiritual Perspective Scale, and the PROMIS® depression measure. Linear mixed model analyses were used, controlling for pertinent covariates. RESULTS: Spirituality, total caregiver burden, and depression remained stable over 6 months. More than 30% of the caregivers had mild to severe depressive symptoms at 3 time points. There was evidence of overall burden influencing depression. Of note was a protective effect of caregivers' spirituality on the relationship between depression and caregiver burden over time (b = -1.35, p = .015). The lower the spirituality, the stronger the relationship between depression and burden, especially regarding subscales of schedule burden, financial burden, and lack of family support. SIGNIFICANCE OF RESULTS: Spirituality was a significant resource for coping with caregiving challenges. This study suggests that comprehensive screening and spiritual care for cancer caregivers may improve their cancer caregiving experience and possibly influence the care recipients' health.
