Background and aims

The Timeline Followback (TLFB) was initially developed to collect retrospective self- reports of alcohol and drug use. Since its development, several peer-reviewed papers have supported it as a sound psychometric measure for substance use and for several other behaviors. Worldwide, coffee is one of the most widely consumed beverages. Although early epidemiological research suggested that drinking coffee is associated with some health problems, several recent studies have found moderate coffee consumption to have an inverse association with mortality. Because of its widespread use, a psychometrically sound measure of coffee consumption would help better inform research and public health policies.

Design

This study investigated the test–retest reliability of a version of the TLFB modified to assess coffee consumption.

Setting and participants

98 clinical psychology doctoral students completed a 30-day coffee TLFB on two occasions separated by 14 days.

Measurements

Participants used a computerized Survey Monkey™ version of the coffee TLFB to report their caffeinated coffee consumption for the same 30-day interval. For the first administration participants reported their consumption for the preceding 30 days, and for the second administration they reported on the preceding 45 days which included the earlier reporting interval.

Findings

Reliability coefficients were found to be very high (0.90–0.97).

Conclusions

As with other substance use versions of the TLFB, these results suggest the TLFB is a good method for measuring coffee consumption in research studies and in primary health care settings where such data may be important.

含咖啡因咖啡消费的时间线跟踪测量的可靠性

背景和目标

时间线追踪 (TLFB) 最初是为了收集酒精和药物使用的回顾性自我报告而开发的。自其开发以来，几篇同行评审的论文支持它作为物质使用和其他几种行为的合理心理测量指标。在世界范围内，咖啡是消费最广泛的饮料之一。尽管早期的流行病学研究表明喝咖啡与一些健康问题有关，但最近的几项研究发现适量饮用咖啡与死亡率呈负相关。由于其广泛使用，对咖啡消费进行心理测量的合理测量将有助于更好地为研究和公共卫生政策提供信息。

设计

本研究调查了用于评估咖啡消耗量的 TLFB 版本的重测可靠性。

背景及参与者

98 名临床心理学博士生两次完成了为期 30 天的咖啡 TLFB，间隔 14 天。

测量

参与者使用计算机化的 Survey Monkey™ 版本的咖啡 TLFB 来报告他们在相同的 30 天间隔内的含咖啡因咖啡消耗量。对于第一次管理，参与者报告了之前 30 天的消耗情况，对于第二次管理，他们报告了之前 45 天的消耗情况，其中包括之前的报告间隔。

发现

可靠性系数被发现非常高（0.90-0.97）。

结论

与 TLFB 的其他物质使用版本一样，这些结果表明 TLFB 是一种在研究和初级卫生保健环境中测量咖啡消耗量的好方法，这些数据可能很重要。
