Subst Use Misuse. 2014 Aug;49(10):1259-69. doi: 10.3109/10826084.2014.891621. Epub 2014 Mar 6.
The timeline follow-back (TLFB) interview was adopted to collect retrospective data on daily substance use and violence from 598 youth seeking care in an urban Emergency Department in Flint, Michigan during 2009-2011. Generalized linear mixed models with flexible smooth functions of time were employed to characterize the change in risk behaviors as a function of the length of recall period. Our results suggest that the 1-week recall period may be more effective for capturing atypical or variable patterns of risk behaviors, whereas a recall period longer than 2 weeks may result in a more stable estimation of a typical pattern.
采用时间回溯访谈(TLFB)收集了2009年至2011年期间在密歇根州弗林特市一家城市急诊科就诊的598名青少年每日物质使用和暴力行为的回顾性数据。使用具有灵活时间平滑函数的广义线性混合模型来描述风险行为随回忆期长度变化的特征。我们的结果表明,1周的回忆期可能更有效地捕捉风险行为的非典型或可变模式,而超过2周的回忆期可能会对典型模式进行更稳定的估计。
