过去的研究表明，性格上对癌症的担忧可能是健康行为的关键预测因素。本研究考察了7种对性格性癌症担忧的测量方法，看看它们是否显著相关（趋同效度），是否与相似但不同的特征显著不同（发散效度），是否能够预测癌症相关的结果（预测效度）。489名大学生完成了一项测量性格担忧、性格癌症担忧和感知癌症风险的调查。因子分析确定了四个潜在维度，解释了67.3%的易感性癌症担忧差异：严重程度（42.8%）、频率（12.3%）、心理抗拒（6.9%）和担忧影响（5.3%）。研究人员发现，现有的四种对性格性癌症担忧的测量方法分别代表了这些维度。总体而言，性情性癌症担忧测量彼此高度相关，与性情性担忧测量仅适度相关，支持强的收敛效度和发散效度。层次回归分析显示，性情性癌症担忧措施预测癌症相关结果的显著差异，超出了性情性担忧。本研究的结果支持了性格性癌症担忧和性格性担忧是不同构念的观点。此外，性格性癌症担忧的两个维度（严重程度和频率）似乎具有最强的收敛效度、发散效度和预测效度。
Past research has suggested that dispositional cancer worry may be a key predictor of health behavior. The present study examined seven measures of dispositional cancer worry to see if they were significantly related (convergent validity), significantly different from similar but distinct traits (divergent validity), and capable of predicting cancer-relevant outcomes (predictive validity). 489 undergraduate students completed a survey measuring dispositional worry, dispositional cancer worry, and perceived cancer risk. Factor analysis identified four underlying dimensions that explained 67.3% of the variance in dispositional cancer worry: severity (42.8%), frequency (12.3%), psychological reactance (6.9%), and worry impact (5.3%). Four existing measures of dispositional cancer worry were found to represent each of these dimensions. In general, dispositional cancer worry measures were highly correlated with one another and only moderately correlated with measures of dispositional worry, supporting strong convergent and divergent validity. Hierarchical regression analyses revealed that dispositional cancer worry measures predicted significant variance in cancer-relevant outcomes above and beyond dispositional worry. The results of this study support the notion that dispositional cancer worry and dispositional worry are distinct constructs. Furthermore, two dimensions of dispositional cancer worry (severity and frequency) seemed to have the strongest convergent, divergent, and predictive validity.
