Timeline Follow-Back (TLFB) is a widely used, calendar-based measure of self-reported use of (among other things) illicit substances. We examined agreement between TLFB and biological measures for illicit substances.
PubMed, PsycINFO, Cochrane CENTRAL, and EMBASE were searched in December 2010. 16,633 papers screened to identify those that measured illicit substance use by both TLFB and biological measures. We extracted data on agreement between TLFB and biological measures, sample size, study type, inclusion criteria of participants, and length of recall of TLFB.
Twenty-nine papers were included, almost exclusively in substance-use-disorder populations. Some studies reported several overall agreement rates, e.g. over time. Lowest and highest weighted average agreement rates were: for cannabis, 87.3% (95% confidence interval 86.9% to 87.7%) and 90.9% (90.5% to 91.4%); for cocaine, 79.3% (79.1% to 79.6%) and 84.1% (83.9% to 84.2%); for opiates 94.0% (93.5% to 94.5%) for both weighted averages; and for studies not distinguishing between substances, 88.5% (88.4 to 88.7%) and 91.0% (90.7% to 91.2%). Higher agreement was found in populations without psychiatric comorbidity, and lower agreement in randomized controlled trials. Publication bias or selective outcome reporting bias was not detected.
TLFB validly detects use of illicit substances in populations with substance use disorders. Using TLFB may limit the need for biological samples, making information on illicit substance use easier and less costly to obtain and analyze.
时间线回溯（TLFB）是一种广泛使用的基于日历的自我报告使用（包括其他方面）非法物质的测量方法。我们检查了 TLFB 与生物测量法在非法物质方面的一致性。
2010 年 12 月，在 PubMed、PsycINFO、Cochrane CENTRAL 和 EMBASE 上进行了搜索。筛选了 16633 篇论文，以确定那些同时使用 TLFB 和生物测量法测量非法物质使用的论文。我们提取了 TLFB 与生物测量法之间的一致性、样本量、研究类型、参与者纳入标准以及 TLFB 回忆的时间长度的数据。
共纳入 29 篇论文，几乎全部来自物质使用障碍人群。一些研究报告了几个总体一致性率，例如随时间变化的一致性率。最低和最高加权平均一致性率分别为：大麻为 87.3%（95%置信区间 86.9%至 87.7%）和 90.9%（90.5%至 91.4%）；可卡因为 79.3%（79.1%至 79.6%）和 84.1%（83.9%至 84.2%）；阿片类药物两者加权平均值均为 94.0%（93.5%至 94.5%）；对于不区分物质的研究，一致性率分别为 88.5%（88.4%至 88.7%）和 91.0%（90.7%至 91.2%）。在没有精神共病的人群中，一致性更高，在随机对照试验中，一致性更低。未发现发表偏倚或选择性结果报告偏倚。
TLFB 可以有效地检测出物质使用障碍人群中非法物质的使用。使用 TLFB 可能会减少对生物样本的需求，使非法物质使用的信息更容易获得和分析，成本也更低。
