To examine whether the method of measuring patient satisfaction influences the results.
All families with NICU patients discharged home alive to parent(s) were surveyed at 2 to 42 days post discharge with two parallel surveys (mailed and phone) from August 2010 to December 2011. The responses to the same five questions on each survey were recorded and subjected to statistical analysis via paired Student's t and Pearson correlation coefficients to see whether the two surveys yielded the same population attitudes.
Eight hundred and thirteen families were included in the study. Seven hundred and sixty three (93.8%) completed the phone survey and 237 (29.2%) completed the mail in survey. Three of the five questions yielded significantly different answers between mailed and phone responses. In addition, no significant linear correlation between mail and survey could be found for the other two questions.
As no linear correlation could be found between two of the five questions, a process constant mathematical value could not be identified. This indicates that mail survey and phone survey respondents have different attitudes that cannot be adjusted because of methodological measurement effects.
检验测量患者满意度的方法是否会影响结果。
2010 年 8 月至 2011 年 12 月，对所有在家中由父母照顾出院的新生儿重症监护病房（NICU）患者的家庭，在出院后 2 至 42 天进行了两次平行调查（邮寄和电话）。记录了每个调查中对相同五个问题的回答，并通过配对学生 t 检验和 Pearson 相关系数进行了统计分析，以了解两次调查是否得出了相同的人群态度。
本研究共纳入 813 个家庭。763 个家庭（93.8%）完成了电话调查，237 个家庭（29.2%）完成了邮件调查。五个问题中的三个问题在邮寄和电话回复之间产生了显著不同的答案。此外，对于另外两个问题，也未发现邮件和调查之间存在显著的线性相关性。
由于无法在五个问题中的两个问题之间找到线性相关性，因此无法确定过程常数的数学值。这表明邮件调查和电话调查的受访者有不同的态度，由于方法测量效果，这些态度无法调整。
