本研究探讨了风险信息寻求和处理模型（RISP）和计划行为理论（TPB）在与临床试验中涉及的潜在风险相关的健康决策背景下的理论联系。在RISP模型提出十年后，大量的经验证据证明该模型在描述个体寻求和处理风险信息的动机方面具有鲁棒性，认为继续进行这一探索至关重要。两项电话调查的数据显示，倾向于以更系统的方式处理相关风险信息的个人更有可能报告对临床试验的有利态度，并表示愿意参加未来的试验。那些报告对医生更信任的人也更有可能报告良好的态度和意愿。相反，风险认知与对临床试验的积极态度呈负相关。比较几个结构模型指定的数据，个人的倾向，依赖于独立的决定似乎缓和主观规范和行为意图之间的关系。使用回归系数估计来绘制这种相互作用，在那些倾向于依赖独立决定的人中，来自医生的影响可能会导致他们不太愿意参加未来的试验。这项研究的结果表明，在一个独特的研究背景下，努力追求理论发展，我们也可以确定重要的途径，以改善与临床试验的患者累积相关的健康沟通实践。
This study examines theoretical linkages between the Risk Information Seeking and Processing model (RISP) and the Theory of Planned Behavior (TPB) in a context of health decision making related to potential risks involved in clinical trials. A decade after the RISP model was proposed, abundant empirical evidence attesting to the model’s robustness in depicting individuals’ motivations for risk information seeking and processing deems that it is crucial to continue this exploration. Data from two telephone surveys showed that individuals who tended to process relevant risk information in a more systematic manner were more likely to report favorable attitudes toward clinical trials and express a willingness to enroll in a future trial. Those who reported greater trust in their doctors were also more likely to report favorable attitudes and willingness to enroll. In contrast, risk perceptions were negatively related to favorable attitudes toward clinical trials. Comparing several structural models specified to the data, individuals’ tendency to rely on independent decisions seemed to moderate the relationship between subjective norm and behavioral intention. Using regression coefficients estimates to plot this interaction, among those who tended to rely on independent decisions, influence from their doctors might lead to less willingness to enroll in a future trial. Results from this study suggest that in an effort to pursue theory development within a unique research context, we could also identify important pathways to improve health communication practice related to patient accrual for clinical trials.
