To investigate how comparable outcomes of medical communication research are when using different patient accrual methods by comparing cancer patients organization members with outpatient clinic patients.
In an experimental video-vignettes study, the impact of oncologist communication on trust was tested. Background characteristics (socio-demographics, trait anxiety, health locus of control and attachment style), reported trust, and the impact of communication on trust were compared between the two groups.
Cancer patient organization members (n=196) were younger and higher educated than clinical patients (n=148). Members felt more personal control over their health (p<.01) but were also more anxious (p<.05). They reported lower trust in general health care (p<.05), in their own oncologist (p<.001) and in the oncologist in the videos (p<.05). The impact of oncologist communication on trust was similar for both groups.
Despite considerable differences in trust levels, both groups appear equally affected by oncologist communication. Thus, although including cancer patient organization members may impact the generalizability of some findings, using these participants to investigate communication appears justified.
Cancer patient organization members may regard their oncologist more critically. Research including both members and patients recruited through hospital clinics could take group membership into account as a possible confounder. Nonetheless, communicating competence, honesty and caring may benefit the relation with these patients similarly as with other patients.
通过比较癌症患者组织成员和门诊患者，研究使用不同患者招募方法时医学沟通研究的可比结果。
在一项实验性视频短片研究中，测试了肿瘤学家沟通对信任的影响。比较了两组之间的背景特征（社会人口统计学、特质焦虑、健康控制点和依恋风格）、报告的信任以及沟通对信任的影响。
癌症患者组织成员（n = 196）比临床患者（n = 148）更年轻且受教育程度更高。成员对自己的健康感觉有更多的个人掌控（p <.01），但也更焦虑（p <.05）。他们报告对一般医疗保健（p <.05）、自己的肿瘤学家（p <.001）以及视频中的肿瘤学家（p <.05）的信任度较低。两组中肿瘤学家沟通对信任的影响相似。
尽管信任水平存在显著差异，但两组似乎同样受到肿瘤学家沟通的影响。因此，尽管纳入癌症患者组织成员可能会影响某些研究结果的普遍性，但使用这些参与者来研究沟通似乎是合理的。
癌症患者组织成员可能会更批判性地看待他们的肿瘤学家。包括成员和通过医院诊所招募的患者的研究可以将群体成员身份作为一个可能的混杂因素考虑在内。尽管如此，沟通能力、诚实和关怀可能会同样有益于与这些患者的关系，就像与其他患者一样。
