The effects of spiritual interventions in patients with cancer: a meta-analysis
1Department of Nursing, Sahmyook University in Seoul, South Korea.
Purpose/Objectives:
To evaluate the effects of a spiritual intervention in patients with cancer.
Data Sources:
Databases searched included both international electronic databases (MEDLINE® via PubMed, Cochrane Library CENTRAL, EMBASE, and CINAHL®) as well as Korean electronic databases (KMBASE, KOREAMED, RISS, KISS, and NANET) through December 2013.
Data Synthesis:
A meta-analysis was conducted of 15 studies involving 14 controlled trials (7 randomized and 7 nonrandomized) with 889 patients with cancer. Spiritual interventions were compared with a usual care control group or other psychosocial interventions. The weighted average effect size across studies was -0.48 (p = 0.006, I2 = 65%) for spiritual well-being, -0.58 (p = 0.02, I2 = 70%) for meaning of life, -0.87 (p = 0.02, I2 = 87%) for anxiety, and -0.62 (p = 0.001, I2 = 73%) for depression.
Conclusions:
The findings showed that spiritual interventions had significant but moderate effects on spiritual well-being, meaning of life, and depression. However, the evidence remains weak because of the mixed study design and substantial heterogeneity.
Implications For Nursing:
Oncology nurses increasingly recognize the significance of the spiritual domain of care. The current study indicates that facilitating spiritual awareness and needs may be a worthwhile nursing intervention for patients with cancer.
