As part of an evaluation of the voluntary health promotion program offered by Johnson & Johnson to its employees, comparisons were made between nonrespondents and respondents (75% of all employees) in the baseline health screen. A survey of randomly selected nonrespondents was conducted in 1979-1980 to collect health and life-style information. Comparisons between respondents and nonrespondents on a multitude of characteristics indicated that the nonrespondents reported life-styles as healthful as those of the respondents with the exception that significantly more nonrespondents reported ever having smoked cigarettes and significantly more female nonrespondents currently smoke. These results suggest that the systematic biases found among nonrespondents in general population health surveys do not exist among this more homogeneous employed population and imply that the participants in the program provide a good estimate of the health status and life-style of the entire workforce.
作为对强生公司为其员工提供的自愿健康促进计划评估的一部分，在基线健康筛查中对未回复者和回复者（占所有员工的75%）进行了比较。1979年至1980年对随机挑选的未回复者进行了一项调查，以收集健康和生活方式信息。对回复者和未回复者在众多特征上的比较表明，未回复者报告的生活方式与回复者一样健康，只是有显著更多的未回复者报告曾经吸烟，且有显著更多的女性未回复者目前仍在吸烟。这些结果表明，在一般人群健康调查中未回复者中发现的系统性偏差在这个更同质化的就业人群中不存在，这意味着该计划的参与者能很好地估计整个劳动力的健康状况和生活方式。
