虽然风险感知是健康行为理论中的一个关键预测因素，但目前的风险概念仅包括一个（审议）或两个（审议vs.情感/经验）维度。本研究测试了一个区分风险感知的审议，情感和经验成分的三方模型。在两项研究中，并与三种常见疾病有关。（癌症、心脏病、糖尿病），我们使用验证性因素分析来检验三方风险认知（TRIRISK）模型的因素结构，并比较TRIRISK模型与双因素和单因素模型的拟合度。在第三项研究中，我们通过检查癌症诊断对（a）审慎、情感和经验风险感知水平以及（B）风险成分之间关系强度的影响来评估并发效度，并通过评估与预防癌症的行为意图的关系来测试预测效度。在被诊断患有癌症的参与者中，各组成部分之间的相互关系显着较小，这表明受影响的人群在风险感知之间进行了更细粒度的区分（研究3）。此外，所有三个风险感知组件预测独特的差异，在意图从事预防行为（研究3）。TRIRISK模型提供了一个新的概念化的健康相关的风险感知，和新的措施，提高预测的有效性超越所产生的一维和二维模型。目前的研究结果有影响的方式，其中风险认知的健康行为改变干预措施，健康传播和决策援助的目标。
Although risk perception is a key predictor in health behavior theories, current conceptions of risk comprise only one (deliberative) or two (deliberative vs. affective/experiential) dimensions.This research tested a tripartite model that distinguishes among deliberative, affective, and experiential components of risk perception.In two studies, and in relation to three common diseases (cancer, heart disease, diabetes), we used confirmatory factor analyses to examine the factor structure of the tripartite risk perception (TRIRISK) model and compared the fit of the TRIRISK model to dual-factor and single-factor models. In a third study, we assessed concurrent validity by examining the impact of cancer diagnosis on (a) levels of deliberative, affective, and experiential risk perception, and (b) the strength of relations among risk components, and tested predictive validity by assessing relations with behavioral intentions to prevent cancer.The tripartite factor structure was supported, producing better model fit across diseases (studies 1 and 2). Inter-correlations among the components were significantly smaller among participants who had been diagnosed with cancer, suggesting that affected populations make finer-grained distinctions among risk perceptions (study 3). Moreover, all three risk perception components predicted unique variance in intentions to engage in preventive behavior (study 3).The TRIRISK model offers both a novel conceptualization of health-related risk perceptions, and new measures that enhance predictive validity beyond that engendered by unidimensional and bidimensional models. The present findings have implications for the ways in which risk perceptions are targeted in health behavior change interventions, health communications, and decision aids.
