摘要:
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31d,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.

Abstract:
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 onhne 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 selfmonitoring rate of sexual behavior was 51.97%.About 8.45% of participants pre-filled the questionnaire.The average time for completing 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.
