Development of a One-item Screening Question to Assess Spiritual Well-Being for Advanced Cancer Inpatients in Korea.

CONTEXT Spiritual well-being (SWB) is significant for patients with life-limiting illnesses. Thus, shortened versions of questions would be helpful in approaching SWB. OBJECTIVES Our goal was to develop a one-item screening question to assess the SWB of advanced cancer inpatients. METHODS This was a cross-sectional, multicenter study involving adult advanced cancer inpatients from seven palliative care units in South Korea. The candidate one-item questions were three questions scored using numeric rating scales from 0 to 10: feeling at peace (Are you at peace?), self-rated spirituality (Do you think of yourself as a spiritual person?), and self-rated religiosity (Do you think of yourself as a religious person?). The Functional Assessment of Chronic Illness Therapy-Spirituality 12 (FACIT-Sp-12) comprised of two subscales Meaning/Peace and Faith was used to assess SWB. Pearson's correlation test was conducted to determine the relationship between the three questions, the total FACIT-Sp-12 score, and its subscales. RESULTS A total of 202 patients were enrolled. A strong correlation was observed between self-rated spirituality (r = 0.732 and 0.790; P < 0.001 and < 0.001 respectively) and religiosity (r = 0.708 and 0.758; P < 0.001 and < 0.001 respectively) with the total FACIT-Sp-12 scores and faith subscale scores. Feeling at peace showed a moderate correlation with the total of FACIT-Sp-12 scores (r = 0.505, P < 0.01). All three questions had a moderate correlation with the meaning/peace subscale. CONCLUSION Self-rated spirituality and religiosity showed better convergence validity than feeling at peace. Therefore, we recommend self-rated spirituality or religiosity as a one-item question for screening SWB in inpatients with advanced cancer.
