Anchoring Vignettes in the Health and Retirement Study: How Do Medical Professionals and Disability Recipients Characterize the Severity of Work Limitations?

PurposeRecent studies report systematic differences in how individuals categorize the severity of identical health and work limitation vignettes. We investigate how health professionals and disability recipients characterize the severity of work limitations and whether their reporting patterns are robust to demographic, education, and health characteristics. We use the results to illustrate the potential impact of reporting heterogeneity on the distribution of work disability estimated from self-reported categorical health and disability data.MethodNationally representative data on anchoring disability vignettes from the 2004 Health and Retirement Study (HRS) are used to investigate how respondents with an occupation background in health and Social Security disability beneficiaries categorize work limitation vignettes. Using pain, cardiovascular health, and depression vignettes, we estimate generalized ordered probit models (N = 2,660 individuals or 39,681 person-vignette observations) that allow the severity thresholds to vary by respondent characteristics.ResultsWe find that health professionals (excluding nurses) and disability recipients tend to classify identical work limitations as more severe compared to non-health professional non-disabled respondents. For disability recipients, the differences are most pronounced and particularly visible in the tails of the work limitations distribution. For health professionals, we observe smaller differences, affecting primarily the classification of mildly and moderately severe work limitations. The patterns for health professionals (excluding nurses) are robust to demographics, education, and health conditions. The greater likelihood of viewing the vignette person as more severely work limited observed among disability recipients is mostly explained by the fact that these respondents also tend to be in poorer health which itself predicts a more inclusive scale.ConclusionsKnowledge of reporting scales from health professionals and disabled individuals can benefit researchers in a broad range of applications in health and disability research. They may be useful as reference scales to evaluate disability survey data. Such knowledge may be beneficial when studying disability programs. Given the increasing availability of anchoring vignette data in surveys, this is a promising area for future evaluation research.【研究目的】已有研究表明，不同个体对相同健康与工作限制情景题（vignette）的严重程度进行分类时存在系统性差异。本研究旨在探究卫生专业人员与残疾领取者如何界定工作限制情景的严重程度，同时验证其报告模式是否不受人口统计学特征、受教育程度与健康状况的影响。本研究还将利用分析结果，阐释报告异质性对基于自我报告分类健康与残疾数据估算的工作残疾分布可能产生的影响。 【研究方法】本研究使用2004年健康与退休研究（Health and Retirement Study, HRS）中具有全国代表性的锚定残疾情景题（anchoring vignettes）数据，针对具有医疗卫生职业背景的受访者与社会保障残疾受益人，分析其对工作限制情景的分类方式。研究选取疼痛、心血管疾病与抑郁三类情景题，构建广义有序概率单位模型（generalized ordered probit models）进行估计，样本覆盖2660名受访者，共计39681条个人-情景题观测数据。该模型允许严重程度阈值随受访者特征发生变化。 【研究结果】研究发现，与非卫生专业人员且非残疾的受访者相比，卫生专业人员（不含护士）与残疾领取者更倾向于将相同的工作限制情景判定为更严重。其中，残疾领取者的分类差异最为显著，尤其在工作限制程度分布的两端体现得尤为突出；而卫生专业人员的分类差异相对较小，主要影响轻度与中度严重程度的工作限制分类。此外，卫生专业人员（不含护士）的分类模式不受人口统计学特征、受教育程度与健康状况的影响。残疾领取者更易将情景中的个体判定为存在更严重的工作限制，这一现象主要可由这类受访者自身健康状况较差所解释——而较差的健康状况本身也预示着他们会采用更宽泛的评分标准。 【研究结论】了解卫生专业人员与残疾群体的报告评分标准，可惠及健康与残疾研究领域的众多应用场景，可作为参考标准用于评估残疾调查数据，在研究残疾保障项目时也颇具价值。鉴于当前调查中锚定情景题数据的可用性不断提升，该领域未来的评估研究前景广阔。
