Young adults who experience homelessness are exposed to environments that contribute to risk behavior. However, few studies have examined how access to housing may affect the health risk behaviors of young adults experiencing homelessness.
This paper describes the Log My Life study that uses an innovative, mixed-methods approach based on geographically explicit ecological momentary assessment (EMA) through cell phone technology to understand the risk environment of young adults who have either enrolled in housing programs or are currently homeless.
For the quantitative arm, study participants age 18-27 respond to momentary surveys via a smartphone app that collects geospatial information repeatedly during a 1-week period. Both EMAs (up to 8 per day) and daily diaries are prompted to explore within-day and daily variations in emotional affect, context, and health risk behavior, while also capturing infrequent risk behaviors such as sex in exchange for goods or services. For the qualitative arm, a purposive subsample of participants who indicated engaging in risky behaviors are asked to complete an in-depth qualitative interview using an interactive, personalized geospatial map rendering of EMA responses.
Recruitment began in June of 2017. To date, 170 participants enrolled in the study. Compliance with EMA and daily diary surveys was generally high. In-depth qualitative follow-ups have been conducted with 15 participants. We expect to recruit 50 additional participants and complete analyses by September of 2019.
Mixing the quantitative and qualitative arms in this study will provide a more complete understanding of differences in risk environments between homeless and housed young adults. Furthermore, this approach can improve recall bias and enhance ecological validity.

经历无家可归的年轻人所处的环境会促使他们产生危险行为。然而，很少有研究探讨获得住房如何影响经历无家可归的年轻人的健康风险行为。
本文介绍了“记录我的生活”研究，该研究采用了一种创新的混合方法，基于通过手机技术进行的地理明确生态瞬时评估（EMA），以了解已参加住房项目或目前无家可归的年轻人的风险环境。
在定量研究部分，年龄在18 - 27岁的研究参与者通过智能手机应用程序对瞬时调查做出回应，该应用程序在1周内反复收集地理空间信息。通过EMA（每天最多8次）和每日日记来探究情绪影响、情境和健康风险行为的日内和每日变化，同时也捕捉诸如以性交易换取物品或服务等不常见的风险行为。在定性研究部分，对那些表示有危险行为的参与者进行有目的的子样本抽样，要求他们使用EMA回应的交互式个性化地理空间地图绘制来完成深入的定性访谈。
招募工作于2017年6月开始。截至目前，有170名参与者登记参加了该研究。对EMA和每日日记调查的依从性总体较高。已对15名参与者进行了深入的定性随访。我们预计再招募50名参与者，并在2019年9月前完成分析。
本研究将定量和定性研究部分相结合，将能更全面地了解无家可归和有住房的年轻人在风险环境方面的差异。此外，这种方法可以减少回忆偏差并提高生态效度。
