The main goal of the research project P5 "Personalized Risk" is to examine (a) trajectories in health risk perception across time, (b) the interplay between changes in risk perceptions and health behaviors across time (Preparedness-Exposure-Coping Cycles, PEC), and c) risk-amplifying and -decreasing mechanisms in the different stages of the PEC Cycle after receiving multiple personalized risk-related feedback ("critical events") in real-life contexts. Two types of risk-related feedback will be studied in two work packages (WPs); one related to secondary prevention (clinical biomarkers, WP1) and one related to primary prevention (health behavior, WP2). Multiple risk feedback will be tailored to the actual individual risk status through objective measures (e.g., blood pressure, lipid levels, WP1) and ecological momentary assessment of real-life behavior (food intake, physical activity, WP2). In order to trace how risk perceptions and risk feedback responses change across time, longitudinal research designs will be implemented with multiple, consecutive measurement points of risk perception and health protective behaviors. We expect differential dynamics across time that are dependent on initial risk perceptions, risk reappraisals, and coping responses and will therefore investigate several risk compensatory mechanisms that might hinder risk decreasing PEC Cycles. In addition, we will investigate the impact of differential preparedness (self-regulatory competence) on dynamic changes. We assume that, for long-term protective (adaptive) behavioral changes, the impact of post-event coping responses, i.e. lifestyle changes, on risk perceptions is highly relevant. The novel data and findings will help to advance theories on risk perception and health behavior and to inform the development of effective risk communication and health behavior change techniques.

研究项目P5“个性化风险”的主要目的是研究(a)健康风险感知在时间上的变化轨迹，（b)风险感知与健康行为的变化在时间上的相互作用（准备-暴露-应对周期，PEC），以及c）在现实环境中接受多个个性化风险相关反馈（“关键事件”）后，PEC周期不同阶段的风险放大和降低机制。将在两个工作包中研究两种与风险有关的反馈；一个与二级预防有关（临床生物标志物，WP1），另一个与一级预防有关（健康行为，WP2）。多重风险反馈将通过客观测量（如血压、脂质水平、WP1）和对现实生活行为的生态瞬时评估（食物摄入、身体活动、WP2），针对个体的实际风险状态进行量身定制。为了追踪风险感知和风险反馈反应如何随时间变化，将采用多个连续的风险感知和健康保护行为测量点实施纵向研究设计。我们预计不同时间的差异动力学取决于初始风险感知、风险重新评估和应对反应，因此我们将研究几种可能阻碍风险降低的风险补偿机制。此外，我们将调查差异准备（自我监管能力）对动态变化的影响。我们假设，对于长期的保护性（适应性）行为改变，事件后应对反应（即生活方式的改变）对风险感知的影响是高度相关的。新的数据和发现将有助于推进风险感知和健康行为的理论，并为有效的风险沟通和健康行为改变技术的发展提供信息。
