本研究的重点是对首次饮酒和吸烟年龄的估计错误。数据来自一项为期 5 年的纵向研究，包含三个测量值。将基线测量时关于首次使用年龄的自我报告与两次后续调查中的类似自我报告进行比较。在后续测量中，青少年更有可能报告首次使用的年龄较高。那些在基线测量中报告吸烟 (n = 338) 或饮酒 (n = 523) 的人分别有 61.7% 和 89% 低估了他们的饮酒年限。与第一次和第三次测量时的估计相比，吸烟者和饮酒者的首次使用年龄一致，分别为 13.6% 和 4.6%。基线测量时关于发病年龄的自我报告与 5 年后吸烟和饮酒的频率和强度相关，以评估发病年龄对以后使用的预测能力。除了一个例外（与 5 年后饮酒强度的相关性，r = .14），没有发现显着的相关性。结果表明，应谨慎使用首次使用年龄这一概念，原因有二：（1）评估可靠性不足；（2）不同估计值与第三次浪潮实际消费频率和强度的相关性不一致。讨论了测量误差的解释以及改进建议。 (C) 1997 爱思唯尔科学有限公司。
This study focuses on errors in estimations of age at which alcohol and tobacco are used for the first time. The data come from a 5-year longitudinal study with three measurements. Self-reports about age of first use at the baseline measurement were compared with similar self-reports at two follow-up surveys. Adolescents were more likely to report a higher age of first use at follow-up measurements. Those who at the baseline measurement re ported having smoked (n = 338) or consumed alcohol (n = 523) 61.7% and 89%, respectively, underestimated their years of use. By comparison with estimations at the first and third measurement, 13.6% for smoking and 4.6% for drinking were consistent about their age of first use. Self-reports about the age of onset at the baseline measurement were correlated with frequency and intensity of tobacco and alcohol use 5 years later to assess the predictive power of age of onset for later use. With one exception (correlation with intensity of alcohol use 5 years later, r = .14) no significant correlation was found. The results show that the concept age of first use should be utilized with caution for two reasons: (1) the reliability of assessment is insufficient, and (2) correlations of different estimates with actual frequency and intensity of consumption at the third wave are inconsistent. Explanations for errors in measurement, and recommendations for improvement, are discussed. (C) 1997 Elsevier Science Ltd.
