OBJECTIVE
To assess the effect of wireless telephone substitution in a survey of health care reform opinions.
DATA SOURCE
Survey of New Jersey adults conducted by landline and wireless telephones from June 1 to July 9, 2007.
STUDY DESIGN
Eighty-one survey measures are compared by wireless status. Logistic regression is used to confirm landline-wireless gaps in support for coverage reforms, controlling for population differences. Weights adjust for selection probability, complex sample design, and demographic distributions.
PRINCIPAL FINDINGS
Significant differences by wireless status were found in many survey measures. Wireless users were significantly more likely to favor coverage reforms. Higher support for government-sponsored universal coverage, income-related state coverage subsidies, and an individual mandate remain after adjustment for demographic variables.
CONCLUSIONS
Opinion polls excluding wireless users are likely to understate support for coverage reforms.
目的
在一项关于医疗改革意见的调查中评估无线电话替代的影响。
数据来源
2007年6月1日至7月9日通过固定电话和无线电话对新泽西州成年人进行的调查。
研究设计
按无线电话使用状况比较81项调查指标。使用逻辑回归来确认在支持覆盖范围改革方面固定电话用户与无线电话用户之间的差距，并控制人口差异。权重针对选择概率、复杂样本设计和人口分布进行调整。
主要发现
在许多调查指标中发现了按无线电话使用状况划分的显著差异。无线电话用户更有可能支持覆盖范围改革。在对人口变量进行调整后，对政府资助的全民覆盖、与收入相关的州覆盖补贴以及个人强制保险的支持率仍然较高。
结论
排除无线电话用户的民意调查可能会低估对覆盖范围改革的支持率。
