The study investigated the utility of the Heuristic-Systematic Processing Model as a framework for the investigation of patient decision making. A total of 111 men recently diagnosed with localized prostate cancer were assessed using Verbal Protocol Analysis and self-report measures. Study variables included men's use of nonsystematic and systematic information processing, desire for involvement in decision making, and the individual differences of health locus of control, tolerance of ambiguity, and decision-related uncertainty. Most men (68%) preferred that decision making be shared equally between them and their doctor. Men's use of the expert opinion heuristic was related to men's verbal reports of decisional uncertainty and having a positive orientation to their doctor and medical care; a desire for greater involvement in decision making was predicted by a high internal locus of health control. Trends were observed for systematic information processing to increase when the heuristic strategy used was negatively affect laden and when men were uncertain about the probabilities for cure and side effects. There was a trend for decreased systematic processing when the expert opinion heuristic was used. Findings were consistent with the Heuristic-Systematic Processing Model and suggest that this model has utility for future research in applied decision making about health.
该研究调查了启发式-系统性加工模型作为患者决策调查框架的效用。总共111名最近被诊断为局限性前列腺癌的男性使用言语协议分析和自我报告测量方法进行了评估。研究变量包括男性对非系统性和系统性信息加工的运用、参与决策的意愿，以及健康控制点、模糊容忍度和决策相关不确定性的个体差异。大多数男性（68%）倾向于他们与医生平等分担决策。男性对专家意见启发式的运用与男性关于决策不确定性的言语报告以及对医生和医疗护理的积极态度有关；对健康有高度内控点预测了更强烈的参与决策的意愿。当所使用的启发式策略带有负面情绪，以及当男性对治愈概率和副作用不确定时，观察到系统性信息加工有增加的趋势。使用专家意见启发式时，有系统性加工减少的趋势。研究结果与启发式-系统性加工模型一致，并表明该模型对未来关于健康应用决策的研究有用。
