The aim was to determine the cross-cultural applicability, reliability, construct and convergent validity of the WHOQOL-SRPB in the Chinese community, and to compare the quality of life of contrasting spiritual groups. The WHOQOL-SRPB and Importance measures were administered to community participants (n = 445) in Hong Kong. The spiritual well-being scale (SWBS) was administered to examine the convergent validity of the SRPB domain. Quotas for three age bands (18–44, 45–64, ≥65) were targeted, within two broad religious groupings: Chinese spiritual (CSG) and Christian (CG). Test–retest reliability over two weeks was assessed in a second sample (n = 68). Confirmatory factor analysis (CFA) and other psychometric tests were performed. Alphas for the original WHOQOL domains were acceptable, ranging from 0.72 to 0.84, and excellent for the SRPB domain (α = .92). Test–retest reliability (ICC) of the SRPB domain (α = .95) and its facets (range .80– .94) was excellent. A confirmatory factor analysis on the SRPB-expanded model suggested a reasonable fit (Chi square/df = 4.78), in spite of a relatively low Comparative Fit Index (0.80). The SRPB domain showed a similar structure to SWBS religious and existential subscales. The nine SRPB facets and their Importance scores discriminate well between CSG and CG. The WHOQOL-SRPB is reliable, valid and applicable for Chinese people with Christian and traditional Chinese Spiritual beliefs to use. SRPB is a distinctive dimension that is conceptually consistent with religious and existential beliefs.
