OBJECTIVE
Cancer predisposition perception refers to the subjective estimation of the likelihood of being diagnosed with cancer in the future. It affects people's behavior concerning cancer screening and prevention. At present, there is no available tool to evaluate cancer predisposition perception. The aim of this study was to translate the cancer predisposition perception scale into simplified Chinese (C-CPPS), and then test its psychometric properties among Chinese patients.
METHODS
In phase I, the CPPS was translated into Chinese, and validated by an expert panel. In phase II, data on reliability and validity was evaluated in terms of construct validity, criterion validity, internal consistency, test-retest reliability, and item-total correlations, with a convenience sample of 208 patients recruited from the colorectal cancer surgical ward.
RESULTS
The C-CPPS had desirable validity and reliability. The scale-level content validity index was 0.96. Exploratory factor analysis indicated that the six-factor structure of the C-CPPS was good fit to the data. Correlation between the C-CPPS and the Brief Illness Perception Questionnaire was statistically significant. Cronbach's α for the entire scale was 0.90 and 0.71-0.95 for five of the six subscales. Item-total correlations ranged from 0.309 to 0.775, and the intraclass correlation coefficient was 0.97.
CONCLUSIONS
The C-CPPS appears to be culturally appropriate, reliable, and valid for assessing cancer predisposition perception among patients with colorectal cancer in China.
目的
癌症易感性认知是指对未来被诊断患有癌症可能性的主观估计。它会影响人们在癌症筛查和预防方面的行为。目前，尚无可用工具来评估癌症易感性认知。本研究的目的是将癌症易感性认知量表翻译成简体中文（C-CPPS），然后在中国患者中测试其心理测量特性。
方法
在第一阶段，将CPPS翻译成中文，并由专家小组进行验证。在第二阶段，通过从结直肠癌外科病房招募的208名患者的便利样本，从结构效度、效标效度、内部一致性、重测信度和项目-总分相关性方面评估信效度数据。
结果
C-CPPS具有良好的效度和信度。量表水平的内容效度指数为0.96。探索性因素分析表明，C-CPPS的六因素结构与数据拟合良好。C-CPPS与简易疾病认知问卷之间的相关性具有统计学意义。整个量表的Cronbach's α为0.90，六个子量表中的五个子量表的Cronbach's α为0.71 - 0.95。项目-总分相关性范围为0.309至0.775，组内相关系数为0.97。
结论
C-CPPS在文化上似乎是合适的，对于评估中国结直肠癌患者的癌症易感性认知是可靠且有效的。
