To test the reliability and the discriminant and convergent validity of the abbreviated Brazilian Portuguese World Health Organization's Quality of Life Instrument - Spirituality, Religion, and Personal Beliefs module (WHOQOL-SRPB BREF).
In a sample of 404 individuals, we applied a general questionnaire, the WHOQOL-BREF, the long-form SRPB, the Brief Religious-Spiritual Coping Scale (RCOPE), and the Beck Depression Inventory (BDI). Priority was given to the 9-item SRPB assessment: its unidimensionality was tested through confirmatory factor analysis and Rasch analysis.
Confirmatory factor analysis of the 9-item SRPB assessment indicated an adjusted model with acceptable fit to data. In the Rasch analysis, general fit measures showed adequate performance. The 9-item SRPB assessment showed good internal consistency (alpha = 0.85), and could differentiate (discriminant validity) between religious and atheist/agnostic respondents (mean = 74.7±14.1 and 56.8±15.5, respectively; t = 6.37; degrees of freedom [df] = 402; p < 0.01) and between non-depressed and depressed respondents (mean = 76.5±12.9 and 67.1±16.5; t = 5.57; df = 190.5; p < 0.01). Correlations (convergent validity) were significant with the positive-RCOPE subscale (r = 0.58, p < 0.01) and the WHOQOL-BREF domains (Pearson coefficient ranging between 0.24 and 0.49; p < 0.01), but were in the negative direction with the negative-RCOPE subscale (r = -0.10, p < 0.05). Correlation with the long-form SRPB domain (r = 0.934) was almost perfect.
The Brazilian Portuguese 9-item SRPB has good psychometric properties and confirmed the findings of the long-form Brazilian Portuguese version and the abbreviated English version.
测试简短巴西葡萄牙语版世界卫生组织生活质量工具-精神信仰模块（WHOQOL-SRPB BREF）的可靠性、区分度和聚合效度。
在 404 名个体的样本中，我们应用了一般问卷、WHOQOL-BREF、长式 SRPB、简短宗教精神应对量表（RCOPE）和贝克抑郁量表（BDI）。9 项 SRPB 评估是优先考虑的：通过验证性因子分析和 Rasch 分析测试其单维性。
9 项 SRPB 评估的验证性因子分析表明，数据拟合的调整模型具有可接受性。在 Rasch 分析中，一般拟合指标表现出良好的性能。9 项 SRPB 评估显示出良好的内部一致性（α=0.85），并且可以区分宗教和无神论/不可知论者的答卷人（平均值分别为 74.7±14.1 和 56.8±15.5；t=6.37；自由度 [df]=402；p<0.01）以及非抑郁和抑郁答卷人（平均值分别为 76.5±12.9 和 67.1±16.5；t=5.57；df=190.5；p<0.01）。与积极的 RCOPE 子量表（r=0.58，p<0.01）和 WHOQOL-BREF 领域（Pearson 系数范围为 0.24 至 0.49；p<0.01）的相关性（聚合效度）显著，但与消极的 RCOPE 子量表呈负相关（r=-0.10，p<0.05）。与长式 SRPB 领域的相关性（r=0.934）几乎是完美的。
简短的巴西葡萄牙语 9 项 SRPB 具有良好的心理测量学特性，证实了长式巴西葡萄牙语版本和简短英语版本的发现。
