我们使用来自青少年健康与发展背景研究的数据——一个在俄亥俄州哥伦布市及其周边地区11-17岁的城市青年的代表性样本——来调查基于智能手机的地理明确生态瞬间评估（GEMA）的可行性和有效性。年龄、种族、家庭收入、对智能手机的熟悉程度和自我控制能力与缺失全球定位系统（GPS）的覆盖有关，而基于GPS的在家时间百分比与基于回忆辅助时空预算数据的在家时间百分比之间的不一致有关。遵守协议的疲劳增加了一周内丢失的GPS，这导致了更多的不一致。尽管观察到一些系统差异，但这些发现提供了证据，证明基于智能手机的GEMA是收集城市青年活动空间数据的可行方法。
We employ data from the Adolescent Health and Development in Context Study-a representative sample of urban youth ages 11-17 in and around the Columbus, OH area-to investigate the feasibility and validity of smartphone-based geographically explicit ecological momentary assessment (GEMA). Age, race, household income, familiarity with smartphones, and self-control were associated with missing global positioning systems (GPS) coverage, whereas school day was associated with discordance between percent of time at home based on GPS-only versus recall-aided space-time budget data. Fatigue from protocol compliance increases missing GPS across the week, which results in more discordance. Although some systematic differences were observed, these findings offer evidence that smartphone-based GEMA is a viable method for the collection of activity space data on urban youth.
