Comparative risk perceptions may rival other types of information in terms of effects on health behavior decisions.
We examined associations between comparative risk perceptions, affect, and behavior while controlling for absolute risk perceptions and actual risk.
Women at an increased risk of breast cancer participated in a program to learn about tamoxifen which can reduce the risk of breast cancer. They reported comparative risk perceptions of breast cancer and completed measures of anxiety, knowledge, and tamoxifen-related behavior intentions. Three months later, the women reported their behavior.
Comparative risk perceptions were positively correlated with anxiety, knowledge, intentions, and behavior 3 months later. After controlling for participants' actual risk of breast cancer and absolute risk perceptions, comparative risk perceptions predicted anxiety and knowledge, but not intentions or behavior.
Comparative risk perceptions can affect patient outcomes like anxiety and knowledge independently of absolute risk perceptions and actual risk information.
比较风险感知可能会与其他类型的信息一样，对健康行为决策产生影响。
在控制绝对风险感知和实际风险的情况下，我们检验了比较风险感知、情感与行为之间的关联。
患有乳腺癌风险增加的女性参与了一个关于他莫昔芬的项目，该药物可以降低乳腺癌的风险。她们报告了对乳腺癌的比较风险感知，并完成了焦虑、知识和他莫昔芬相关行为意向的测量。3 个月后，女性报告了她们的行为。
比较风险感知与 3 个月后的焦虑、知识、意向和行为呈正相关。在控制了参与者的实际乳腺癌风险和绝对风险感知后，比较风险感知可以预测焦虑和知识，但不能预测意向或行为。
比较风险感知可以独立于绝对风险感知和实际风险信息，影响患者的焦虑和知识等结果。
