BACKGROUND
This study demonstrates the use of geographic ecological momentary assessment (GEMA) methods among young adult marijuana users.
METHOD
Participants were 14 current marijuana users ages 21-27 living in Greater Seattle, Washington. They completed brief surveys four times per day for 14 consecutive days, including measures of marijuana use and desire to use. They also carried a GPS data logger that tracked their spatial movements over time.
RESULTS
Participants completed 80.1% of possible EMA surveys. Using the GPS data, we calculated daily number of exposures to (i.e., within 100-m of) marijuana retail outlets (mean = 3.9 times per day; SD = 4.4) and time spent per day in high poverty census tracts (mean = 7.3 h per day in high poverty census tracts; SD = 5.1).
CONCLUSIONS
GEMA may be a promising approach for studying the role spatio-temporal factors play in marijuana use and related factors.
背景
本研究展示了地理生态瞬间评估（GEMA）方法在年轻成年大麻使用者中的应用。
方法
参与者为 14 名年龄在 21-27 岁之间、居住在华盛顿州西雅图大都市区的当前大麻使用者。他们在连续 14 天内每天完成 4 次简短的调查，包括大麻使用和使用意愿的测量。他们还携带一个 GPS 数据记录器，记录他们随时间的空间移动。
结果
参与者完成了 80.1%的可能 EMA 调查。使用 GPS 数据，我们计算了每天接触（即在 100 米内）大麻零售店的次数（平均每天 3.9 次；SD=4.4）和每天在高贫困普查区度过的时间（高贫困普查区每天 7.3 小时；SD=5.1）。
结论
GEMA 可能是研究时空因素在大麻使用和相关因素中所起作用的一种很有前途的方法。
