Associations between personality and self-reported health problems may be biased by reporting heterogeneity, that is, tendency to rate the severity of the same health problem differently. This study used hypothetical health vignettes to examine the magnitude of such heterogeneity. Participants were from Health and Retirement Study (HRS; = 3950; mean age 65 years, range from 30 to 97) and Wisconsin Longitudinal Study (WLS; = 8664; mean age 64 years, range from 34 to 87). Personality traits of the Five Factor Model (extraversion, emotional stability, agreeableness, conscientiousness, and openness to experience) were only weakly associated with vignette ratings (s < 0.10). Associations between personality and self-reported health problems were not substantially changed when the thresholds of self-reported severity were allowed to vary by personality, based on the participants' ratings of the vignettes. Reporting heterogeneity does not appear to be a major source of bias in the associations between personality traits and self-reported health problems.
人格与自我报告的健康问题之间的关联可能会受到报告异质性的影响，也就是说，对同一健康问题严重程度的评分存在差异的倾向。本研究使用假设的健康案例来检验这种异质性的程度。参与者来自健康与退休研究（HRS；n = 3950；平均年龄65岁，范围从30到97岁）和威斯康星纵向研究（WLS；n = 8664；平均年龄64岁，范围从34到87岁）。五因素模型的人格特质（外向性、情绪稳定性、宜人性、尽责性和开放性）与案例评分的关联较弱（r < 0.10）。根据参与者对案例的评分，当自我报告严重程度的阈值允许因人格而异时，人格与自我报告的健康问题之间的关联没有实质性变化。报告异质性似乎不是人格特质与自我报告的健康问题之间关联偏差的主要来源。
