目的探讨使用移动的手机对注射吸毒青少年（PWID）进行情绪和注射危险行为生态瞬时评估（EMA）的可接受性和可行性。参与者是185名年龄在18到35岁之间的PWID，他们是从芝加哥的一个大型注射器服务项目的两个地点招募的。在完成基线访谈后，参与者使用移动的手机应用程序对15天的情绪，物质使用和注射风险行为的瞬时调查做出回应。参与者被分配每天接受4、5或6次调查。参与者为68%男性，61%非西班牙裔白色，24%西班牙裔，5%非西班牙裔黑人。在185例受试者中，8%（n=15）未能完成任何EMA评估。在170例EMA应答者中，报告的平均天数为10天（SD 4.7），完成评估的平均比例为0.43（SD 0.27），76%（n=130）完成了随访。在调整年龄和人种/种族的分析中，女性在报告天数（IRR=1.33，95% CI 1.13-1.56）和完成的调查总数（IRR=1.51，95% CI 1.18-1.93）方面比男性对EMA调查的反应更大。无家可归的参与者在更少的天数（IRR=0.76，95% CI 0.64-0.90）和完成更少的调查（IRR=0.70，95% CI 0.54-0.91），并且不太可能返回进行随访（p=0.016）。EMA反应性不受分配的每日评估次数的显著影响。这项研究证明了EMA在年轻PWID中的高可接受性和可行性，每天最多6次调查提示。然而，无家可归严重阻碍了成功参与。
To test the acceptability and feasibility of ecological momentary assessment (EMA) of mood and injection risk behavior among young people who inject drugs (PWID), using mobile phones. Participants were 185 PWID age 18 to 35 recruited from two sites of a large syringe service program in Chicago. After completing a baseline interview, participants used a mobile phone app to respond to momentary surveys on mood, substance use, and injection risk behavior for 15 days. Participants were assigned to receive surveys 4, 5, or 6 times per day. Participants were 68% male, 61% non-Hispanic white, 24% Hispanic, and 5% non-Hispanic Black. Out of 185 participants, 8% (n=15) failed to complete any EMA assessments. Among 170 EMA responders, the mean number of days reporting was 10 (SD 4.7), the mean proportion of assessments completed was 0.43 (SD 0.27), and 76% (n=130) completed the follow-up interview. In analyses adjusted for age and race/ethnicity, women were more responsive than men to the EMA surveys in days reporting (IRR=1.33, 95% CI 1.13–1.56), and total number of surveys completed (IRR=1.51, 95% CI 1.18–1.93). Homeless participants responded on fewer days (IRR=0.76, 95% CI 0.64–0.90) and completed fewer surveys (IRR=0.70, 95% CI 0.54–0.91), and were less likely to return for follow-up (p=0.016). EMA responsiveness was not significantly affected by the number of assigned daily assessments. This study demonstrated high acceptability and feasibility of EMA among young PWID, with up to 6 survey prompts per day. However, homelessness significantly hampered successful participation.
