Intuitive cancer risk perceptions may inform strategies to motivate cancer prevention behaviors. This study evaluated factor structure and measurement invariance of two new measures of intuitive cancer risk, the Cognitive Causation and Negative Affect in Risk scales. Single- and multiple-group confirmatory factor analysis models were fit to responses from three diverse samples. The confirmatory factor analysis models fit the data well, with all comparative fit indices (CFI) ≥ 0.94. Items flagged by chi-square difference tests as potentially non-invariant were largely invariant between samples according to practical fit indices (e.g. ΔCFI). These novel scales may be particularly relevant in diverse, underserved populations.
直观的癌症风险感知可能为激励癌症预防行为的策略提供信息。本研究评估了两种新的直观癌症风险测量方法的因素结构和测量不变性，即认知因果关系和风险的消极影响量表。单组和多组验证性因子分析模型适用于三个不同样本的反应。验证性因子分析模型很好地拟合了数据，所有比较拟合指数（CFI）≥0.94。根据实用拟合指数（例如ΔCFI），通过卡方差异检验标记为潜在不变的项目在样本之间基本不变。这些新的量表在多样化、服务不足的人群中可能特别相关。
