To evaluate different techniques intended to motivate community residents to have their blood pressures taken, five inner-city target areas with comparable, predominantly Black, populations were selected. A sample of about 200 households in each of four areas were subjected to different motivational interventions; in one of these four areas, households were approached in a series of four sequential steps. The fifth target area served as a control. Findings establish that home visits by community members trained to take blood pressure measurements (BPMs) in the home produces much larger yields of new (previously unknown) hypertensives than more passive techniques such as invitational letters and gift offers. Prior informational letters, including letters specifying time of visit, do not affect refusals or increase the yield. More "passive" motivational techniques yield a higher proportion of previously known hypertensives than the more "active" outreach efforts.
为评估旨在激励社区居民测量血压的不同技术，选取了五个市中心的目标区域，这些区域的人口以黑人为主且具有可比性。四个区域中每个区域约200户家庭样本接受了不同的激励干预；在这四个区域中的一个，通过四个连续步骤接触家庭。第五个目标区域作为对照。研究结果表明，由经过培训可在家中测量血压的社区成员进行家访，与诸如邀请函和礼品提供等更为被动的技术相比，能发现更多新的（此前未知的）高血压患者。事先的信息信件，包括指明家访时间的信件，并不会影响拒绝率或提高发现率。与更为“主动”的外展工作相比，更多“被动”的激励技术能发现更高比例的已知高血压患者。
