To assess whether adults with bothersome tinnitus will complete multiple ecological momentary assessments (EMAs) per day, including those during a therapeutic intervention trial. EMA is defined as repeated sampling of subjects' current behaviors and experiences in real time.
Twelve-week longitudinal cohort study conducted from August 28, 2017, to December 14, 2017.
Online only.
Thirty adults with self-reported bothersome nonpulsatile tinnitus of >6 months' duration.
Participants completed 2 weeks of EMA text surveys 7 times per day (preintervention), followed by 8 weeks of EMA questions 4 times per day (during intervention), concluding with 2 weeks of EMA questions 7 times per day (postintervention) for a total of 420 surveys over 12 weeks. During the 8-week intervention period, participants used a commercially available auditory-intensive online cognitive brain training program for 20 minutes per day, 5 times per week (total, 800 minutes). The primary outcome measures were compliance with EMA surveys, as measured by survey response rates, and participant-reported effects of EMA on their tinnitus bother.
Of the 30 participants in this study (20 women and 10 men; median age, 54 years [range, 47-64 years]), 25 participants completed the study protocol (83%). Participants completed a median 87% of EMA surveys (range, 67%-99%). Qualitative analysis of free-text responses found that participants did not report negative side effects of the EMA.
Excellent participant compliance can be achieved with multiweek temporally rigorous EMA sampling. EMA sampling can successfully be conducted during an intervention. EMA is a promising sampling methodology in tinnitus research.
评估有烦扰性耳鸣的成年人是否会每天完成多次生态瞬时评估（EMA），包括治疗干预试验期间的评估。EMA 定义为对受试者当前行为和体验的实时重复采样。
2017 年 8 月 28 日至 2017 年 12 月 14 日进行的为期 12 周的纵向队列研究。
仅限在线。
30 名有自我报告的烦扰性非搏动性耳鸣超过 6 个月的成年人。
参与者在干预前完成了 2 周每天 7 次 EMA 文本调查，然后在干预期间每天 4 次完成 8 周 EMA 问题，最后在干预后每天 7 次完成 2 周 EMA 问题，共 12 周内完成 420 次调查。在 8 周的干预期间，参与者每天使用一种商业上可获得的听觉密集型在线认知脑训练计划 20 分钟，每周 5 次（总计 800 分钟）。主要观察指标为 EMA 调查的依从性，以调查应答率衡量，以及参与者报告的 EMA 对其耳鸣困扰的影响。
在这项研究的 30 名参与者中（20 名女性和 10 名男性；中位数年龄为 54 岁[范围，47-64 岁]），25 名参与者完成了研究方案（83%）。参与者完成了 EMA 调查的中位数 87%（范围，67%-99%）。对自由文本回复的定性分析发现，参与者没有报告 EMA 的负面副作用。
可以通过多周严格的 EMA 采样实现极好的参与者依从性。EMA 采样可以在干预期间成功进行。EMA 是耳鸣研究中一种很有前途的采样方法。
