Health Reform Monitoring Survey, United States, First Quarter 2014

Each quarterly HRMS sample is drawn from the KnowledgePanel, a probability-based, nationally representative Internet panel maintained by GfK Custom Research. Beginning with the second quarter of 2013, the HRMS includes oversamples of adults with family incomes at or below 138 percent of the federal poverty level and adults from selected state groups based on (1) the potential for gains in insurance coverage in the state under the ACA as estimated by the Urban Institute's microsimulation model and (2) states of specific interest to the HRMS funders. Additional funders have supported oversamples of adults from individual states or subgroups of interest (including children). However, ICPSR received data only for the adults in the general national sample and the income and state group oversamples.每季度HRMS样本均取自捷孚凯定制研究（GfK Custom Research）维护的、基于概率抽样的全国代表性互联网面板——知识面板（KnowledgePanel）。自2013年第二季度起，HRMS纳入了两类成年人的过度抽样：一是家庭收入处于或低于联邦贫困线138%的成年人；二是基于两项标准筛选的特定州群体成年人：其一为城市研究所（Urban Institute）通过微观模拟模型估算的、在《平价医疗法案》（ACA）框架下该州医保覆盖范围有望扩大的州；其二为HRMS资助方重点关注的州。另有部分资助方支持了对特定州成年人或目标子群体（含儿童）的过度抽样。但政治与社会研究大学联盟（ICPSR）仅获取了全国通用样本中的成年人数据，以及基于收入和州群体的过度抽样数据。
