摘要
目的探索生态瞬时评估(ecological momentary assessment,EMA)技术在大学生性行为监测中的可行性,为更好地监测大学生性行为提供技术支持。方法通过立意抽样与滚雪球抽样,依据"信息饱和"原则,招募发生过性行为的20名大学生进行个别深入访谈,了解其参与EMA的意愿、顾虑以及建议,据此制订EMA计划,开展可行性试点研究,采用经验抽样法和自我监测法收集资料。结果参与访谈的20名大学生中,17名(85%)访谈对象同意参加,实际15名参加了EMA可行性试点。试点期31 d,发布465次填写指令,获得438份反馈信息,平均反馈率为94.19%;经验抽样法的平均反馈率为80.43%,平均超时率为14.97%;性行为自我监测率为51.97%;提前填报的平均发生率为8.45%;问卷平均完成时间经验抽样法为1.33 min,自我监测法为4.67 min。结论 EMA退出率低、反馈率高、超时情况较少,在充分取得调查对象信任的前提下,对大学生进行性行为EMA可行。
Objective To evaluate the feasibility of ecological momentary assessment （EMA） in monitoring sexual behaviors among college students. Methods Based on the principle of information saturation, the in-depth interviews were conducted via purposive sampling and snowball sampling among college students who have had sex. Willingness, concerns and suggestions of EMA participation were analyzed. The experience sampling method was used as a tool to support self-monitoring. Results Twenty college students participated the interview, of whom 17 （85%） agreed and 15 students attended the EMA feasibility pilot study. During the 31-day trial, 465 times instructions were released, 438 online questionnaires were obtained, and the average response rate was 94.19%. The average feedback rate of empirical sampling method was 80.43% and the average timeout rate was 14.97%. The self-monitoring rate of sexual behavior was 51.97%. About 8.45% of participants pre-filled the questionnaire. The average time for com- pleting questionnaire was 1.33 minutes （empirical sampling method） / 4.67 minutes （self-monitoring method）. Conclusion EMA shows low drop-out rate, high feedback rate and less timeout. It is feasible among college students to collect information on sexual behaviors in terms of establishing trust among participants.
