This project studied the convergent validity of current recall of tobacco-related health behaviors, compared with prospective self-report collected earlier at two sites. Cohorts were from the Oregon Research Institute at Eugene (N = 346, collected 19.5 years earlier) and the University of Pittsburgh, Pennsylvania (N = 294, collected 3.9 years earlier). Current recall was examined through computer-assisted interviews with the Lifetime Tobacco Use Questionnaire from 2005 through 2008. Convergent validity estimates demonstrated variability. Validity estimates of some tobacco use measures were significant for Oregon subjects (age at first cigarette, number of cigarettes/day, quit attempts yes/no and number of attempts, and abstinence symptoms at quitting; all P < 0.03). Validity estimates of Pittsburgh subjects' self-reports of tobacco use and abstinence symptoms were significant (P < 0.001) for all tobacco use and abstinence symptoms and for responses to initial use of tobacco. These findings support the utility of collecting recalled self-report information for reconstructing salient lifetime health behaviors and underscore the need for careful interpretation.
本研究旨在探讨当前对与烟草相关的健康行为的回忆与前瞻性自报数据之间的聚合效度，并对两个地点的前瞻性自报数据进行了比较。队列来自于俄勒冈州尤金市的俄勒冈研究协会（n = 346，收集时间为 19.5 年前）和宾夕法尼亚州匹兹堡大学（n = 294，收集时间为 3.9 年前）。通过 2005 年至 2008 年期间的计算机辅助访谈，使用终生烟草使用问卷对当前的回忆进行了检查。聚合效度估计显示出一定的变异性。一些烟草使用测量的效度估计对俄勒冈州受试者有意义（首次吸烟年龄、每日吸烟量、戒烟尝试的有无和次数、戒烟时的戒断症状；所有 P < 0.03）。匹兹堡受试者的自我报告的烟草使用和戒断症状的效度估计对所有烟草使用和戒断症状以及对初始使用烟草的反应都具有显著意义（P < 0.001）。这些发现支持了收集回忆性自我报告信息以重建重要的终生健康行为的实用性，并强调了需要仔细解释的必要性。
