Our objective was to validate a Social Vulnerabilities Survey that was developed to identify patient barriers in the following domains: (1) salience or priority of health; (2) social support; (3) transportation; and (4) finances.
Cross-sectional psychometric study.Questions for one domain (health salience) were developed de novo while questions for the other domains were derived from national surveys and/or previously validated questionnaires. We tested construct (ie, convergent and discriminative) validity for these new questions through hypothesis testing of correlations between question responses and patient characteristics. Exploratory factor analysis was conducted to determine structural validity of the survey as a whole.
Patients admitted to the inpatient internal medicine service at a tertiary care hospital in Calgary, Canada.
A total of 406 patients were included in the study.
The mean age of respondents was 55.5 (SD 18.6) years, with the majority being men (55.4%). In feasibility testing of the first 107 patients, the Social Vulnerabilities Survey was felt to be acceptable, comprehensive and met face validity. Hypothesis testing of the health salience questions revealed that the majority of observed correlations were exactly as predicted. Exploratory factor analysis of the global survey revealed the presence of five factors (eigenvalue >1): social support, health salience, drug insurance, transportation barriers and drug costs. All but four questions loaded to these five factors.
The Social Vulnerabilities Survey has face, construct and structural validity. It can be used to measure modifiable social vulnerabilities, such that their effects on health outcomes can be explored and understood.
我们的目的是验证一项社会脆弱性调查，该调查旨在确定以下领域的患者障碍：（1）健康的显著或优先性；（2）社会支持；（3）交通；和（4）财务。
横断面心理测量研究。一个领域（健康显著性）的问题是全新开发的，而其他领域的问题则来自国家调查和/或以前验证过的问卷。我们通过假设检验问题回答与患者特征之间的相关性来测试这些新问题的构建（即收敛和鉴别）有效性。进行探索性因子分析以确定调查作为一个整体的结构有效性。
加拿大卡尔加里一家三级保健医院的住院内科患者。
共有 406 名患者参与了这项研究。
受访者的平均年龄为 55.5（18.6）岁，其中大多数是男性（55.4%）。在对前 107 名患者的可行性测试中，社会脆弱性调查被认为是可以接受的、全面的，并且符合表面有效性。健康显著性问题的假设检验表明，大多数观察到的相关性与预测完全一致。对全球调查的探索性因子分析显示存在五个因素（特征值>1）：社会支持、健康显著性、药物保险、交通障碍和药物成本。除了四个问题外，所有问题都加载到这五个因素中。
社会脆弱性调查具有表面、构建和结构有效性。它可用于衡量可改变的社会脆弱性，以便可以探索和理解它们对健康结果的影响。
