作者先前研究了通过电话调查评估的自我报告的心血管疾病（CVD）风险因素的有效性，发现有效性较低，特别是对于自我报告的高血压和高胆固醇血症。提高有效性的一种方法是将联合收割机重复测量（双重响应）组合成单个测量。作者探讨了这一点，并从1989年1月至1990年5月在三个纽约县的行为危险因素调查收集的自报CVD数据的可靠性。对911名调查对象进行电话访谈，收集心血管病危险因素和健康行为信息。受访者接受了体格检查和实验室测试，以验证自我报告的心血管疾病风险因素; 628人参与。受试者也重新采访，以评估重测信度的调查，并研究如何有效性的自我报告的CVD数据的变化，双重响应。心血管疾病的危险因素，预防保健措施，和风险因素水平的知识的可靠性系数范围从0.42到0.99。使用双重应答发现自我报告的危险因素的敏感性改善最小，并且没有改善特异性。此外，对于危险因素的患病率，与客观估计值相比，双重应答最低限度地改善了自我报告的患病率。结合自我报告的测量结果导致这些变量的有效性变化最小。高血压和高胆固醇血症的生理评估，或纠正错误分类，需要有效的个人测量和社区流行率估计电话调查。自我报告的吸烟，肥胖和糖尿病有更好的有效性，但生理评估或纠正错误分类可能会补充这些自我报告的危险因素。
The authors previously studied the validity of self-reported cardiovascular disease (CVD) risk factors assessed by telephone surveys, and found the validity low, especially for self-reported hypertension and hypercholesterolemia. One way to improve validity is to combine repeated measurements (dual response) into a single measure. The authors explored this and the reliability of self-reported CVD data collected by the Behavioral Risk Factor Survey in three New York counties from January 1989 to May 1990. Nine hundred and eleven subjects were interviewed by telephone to collect CVD risk factor and health behavior information. Interviewees were offered physical examination and laboratory testing to verify self-reported CVD risk factors; 628 participated. Subjects were also reinterviewed to assess the test-retest reliability of the survey, and to study how validity of self-reported CVD data changes by dual response. Reliability coefficients for CVD risk factors, preventive health practices, and knowledge of risk factor levels ranged from 0.42 to 0.99. Minimal improvement in sensitivity of self-reported risk factors was found using dual response, and it did not improve specificity. Also, for prevalence of risk factors, dual response minimally improved self-reported rates compared to objective estimates. Combining self-reported measurements causes minimal changes in the validity of these variables. Physiological assessment for hypertension and hypercholesterolemia, or correction for misclassification, is needed for valid individual measurement and for community prevalence estimates from telephone surveys. Self-reported cigarette smoking, obesity, and diabetes mellitus have better validity, but physiological assessment or correction for misclassification may supplement these self-reported risk factors.
