这项分析的目的是确定家庭收入对结直肠癌(CRC)幸存者的心理幸福感(PWB)中解释的差异的独特贡献。这项研究是对作为长期结直肠癌幸存者健康相关生活质量研究的一部分收集的数据的二次分析，该研究包括有(病例)造口和没有(对照)造口的结直肠癌幸存者。数据集包括社会人口、健康状况和与健康相关的生活质量(HRQOL)信息。采用改良的希望之城生活质量量表(mCOH-QOL)-造口问卷和SF-36v2量表评定患者的生活质量。为了评估收入和PWB之间的关系，结合病例和对照的数据，构建了一个层次线性回归模型。在考虑了模型中其他自变量解释的PWB的变异比例后，收入解释的额外变异显著(R2从0.228增加到0.250；p=0.006)。虽然研究设计不允许因果推断，但这些结果表明，在结直肠癌幸存者中，收入和PWB之间存在显著的关系。研究结果表明，对于HRQOL的非随机组比较，至少应该将收入作为控制变量包括在分析中。
The purpose of this analysis was to determine the unique contribution of household income to the variance explained in psychological well-being (PWB) among a sample of colorectal cancer (CRC) survivors. This study is a secondary analysis of data collected as part of the Health-Related Quality of Life in Long-Term Colorectal Cancer Survivors Study, which included CRC survivors with (cases) and without (controls) ostomies. The dataset included socio-demographic, health status, and health-related quality of life (HRQOL) information. HRQOL was assessed with the modified City of Hope Quality of Life (mCOH-QOL)-Ostomy questionnaire and SF-36v2. To assess the relationship between income and PWB, a hierarchical linear regression model was constructed combining data from both cases and controls. After accounting for the proportion of variance in PWB explained by the other independent variables in the model, the additional variance explained by income was significant (R2 increased from 0.228 to 0.250; p = 0.006). Although the study design does not allow causal inference, these results demonstrate a significant relationship between income and PWB in CRC survivors. The findings suggest that for non-randomized group comparisons of HRQOL, income should, at the very least, be included as a control variable in the analysis.
