Perception of risk of getting heart disease is an important predictor of individuals' engagement in a healthy lifestyle. This study describes the development and testing of the Perception of Risk of Heart Disease Scale (PRHDS). The 20-item instrument was tested in successive steps with 295 individuals for internal consistency, test-retest reliability, and construct validity. The three subscales of dread risk, risk, and unknown risk had internal consistency values ranging from .68 to .80. The total scale alpha was .80. Evidence of the instrument's stability over time was supported by subscale test-retest reliabilities ranging from .61 to .76. Construct validity was documented with a positive correlation between PRHDS and the Health Promotion Lifestyle Profile II (r = .20 to .39). Further psychometric testing of the PRHDS in a larger sample with a heterogeneous cultural background is recommended.
对患心脏病风险的认知是个体参与健康生活方式的一个重要预测指标。本研究描述了心脏病风险认知量表（PRHDS）的开发与测试。该包含20个条目的工具在连续步骤中对295名个体进行了内部一致性、重测信度和结构效度测试。恐惧风险、风险和未知风险这三个子量表的内部一致性值在0.68至0.80之间。总量表的阿尔法系数为0.80。子量表重测信度在0.61至0.76之间，支持了该工具随时间稳定性的证据。PRHDS与健康促进生活方式概况II之间呈正相关（r = 0.20至0.39），证明了结构效度。建议在具有异质文化背景的更大样本中对PRHDS进行进一步的心理测量测试。
