我们研究了自我报告的定期吸烟开始年龄的伸缩偏见的证据。由于发病的确切年份不可用，因此探索了自我报告中的差异（称为偏移）。研究的目的，是要确立烟草使用的普遍程度、烟草使用转变的幅度与受访者及调查对象的特征之间的关系，以及找出导致烟草使用转变的主要因素。使用了这两年中当前和既往吸烟者报告的常规吸烟开始年龄。所有的统计分析纳入了重复的权重，以调整复杂的调查design.In我们的样本中，约31.6%（31.8%）的受访者向前（向后）移动吸烟开始年龄，与平均幅度的差异约2.7年（两个方向）。发病后经过的时间被证明是最重要的考虑预测的患病率的转变。随着时间的推移，向前（向后）移动的流行趋势会增加（减少）。此外，平均而言，随着时间的推移，前移反应的差异往往会增加，研究结果表明，在吸烟开始年龄的报告中，前移和后移可能是普遍的。变化的程度取决于自发病以来经过的时间（因此也取决于答卷人的年龄）以及答卷人和调查对象的其他特点。研究结果是一致的存在向前和向后的伸缩偏见。
We examined the evidence of telescoping bias in self-reports of regular smoking onset age. Since the exact year of the onset was not available, the discrepancy (termed shift) in self-reports was explored. The study was targeted at establishing the relationships between the prevalence and the magnitude of shifting and respondent and survey characteristics and identifying the key factors contributing to forward and backward shifting.The 2002-2003 Tobacco Use Supplement to the Current Population Survey was administered using phone and in-person interviews to the same respondents in 2002 and 2003. The regular smoking onset age, reported by current and former smokers during both years, was used. All statistical analyses incorporated replicate weights to adjust for the complex survey design.In our sample, about 31.6% (31.8%) of respondents forwardly (backwardly) shifted the smoking onset age, with the mean magnitude of discrepancy about 2.7 years (both directions). The elapsed time since the onset was shown to be the most important considered predictor of prevalence of shifting. The prevalence of forward (backward) shifting tends to increase (decrease) as elapsed time increases. Furthermore, the discrepancy in forwardly shifted responses tends to increase, on average, with elapsed time.The findings indicate that both forward and backward shifting may be prevalent in reports on smoking onset age. The extent of shifting depends on elapsed time since the onset (and therefore, the respondent's age) and other respondent and survey characteristics. The findings are consistent with presence of both forward and backward telescoping biases.
