根据全国健康访谈调查（NHIS），仅使用手机的家庭数量继续增长，到2006年底占所有家庭的12.8%。皮尤研究中心在2006年进行了四项独立的双框架研究，以评估座机电话样本中由于没有只使用手机的家庭而产生的潜在偏见的程度和性质，其中三项研究至少采访了200名只使用手机的受访者。尽管在许多重要变量上，纯蜂窝电话和固定电话受访者之间存在显著差异，但在四项具有不同实质性内容的调查中，我们发现，将纯蜂窝电话样本与固定电话RDD样本相结合，产生的总体人口估计值接近
The number of cell phone only households has continued to grow - 12.8 percent of all households by the end of 2006, according to the National Health Interview Survey (NHIS). To assess the extent and nature of the potential bias in landline telephone samples created by the absence of cell-only households, the Pew Research Center conducted four independent dual frame studies in 2006, three of which included at least 200 interviews with cell-only respondents. Despite the fact that there are significant differences between cell-only and landline respondents on many important variables, across the four surveys with different substantive content we find that including a cell-only sample with a landline RDD sample produces general population estimates that are nearly
