To investigate the reliability and validity of retrospectively reported information on smoking.
Nationally representative retrospective data from longitudinal surveys and contemporaneous data from repeated cross-sectional surveys were used.
Adult respondents to three of the four samples of the National Longitudinal Surveys Original Cohort 1966-68; the National Longitudinal Survey of Youth 1979; and various waves of the US National Health Interview Survey.
Reliability was investigated by calculating kappa statistics for repeated measures of ever-smoking and annual-smoking status. Validity was investigated by comparing smoking prevalence rates generated by retrospective data with contemporaneously measured rates.
Kappa statistics indicated the repeated measures of ever-smoking status show substantial agreement; repeated measures of annual-smoking status show moderate agreement. Retrospective reports on smoking behavior produced prevalence rates that match reasonably well with those from contemporaneous reports of smoking behavior.
Retrospective data on smoking can be an important resource for tobacco addiction research.
调查吸烟回顾性报告信息的可靠性和有效性。
使用了来自纵向调查的具有全国代表性的回顾性数据以及来自重复横断面调查的同期数据。
1966 - 1968年全国纵向调查原始队列四个样本中的三个样本的成年受访者；1979年全国青年纵向调查；以及美国国家健康访谈调查的各轮调查。
通过计算曾经吸烟和年度吸烟状况重复测量的kappa统计量来调查可靠性。通过比较回顾性数据产生的吸烟流行率与同期测量的流行率来调查有效性。
kappa统计量表明，曾经吸烟状况的重复测量显示出高度一致性；年度吸烟状况的重复测量显示出中等一致性。吸烟行为的回顾性报告产生的流行率与吸烟行为同期报告的流行率相当匹配。
吸烟回顾性数据可以成为烟草成瘾研究的重要资源。
