What is this study trying to understand?
Based on the public registry summary, this study is trying to understand: This is a pilot study of 55 adult male veterans with PTSD. The study will test a new mobile application "app" that can be run on an iPhone10. The app, which is called the Mobile Acoustic startle Reflex-monitoring System (a.k.a., MARS), will be used to measure participant's. The study team can confirm the exact objective and what it means for you.
Does this study involve a device, app, or technology?
This appears to be a device / app / digital / technology study involving Mobile Acoustic startle Reflex monitoring System (MARS). The phase is not clearly listed in the public registry. Phase is mostly relevant for medication studies and some device studies. For this study, it may be more useful to look at what is required, the duration, visits, and eligibility criteria.
Who might this study be for?
This study may concern people with ptsd; age range: Over 18 Years. The criteria appear fairly specific, but you should not assume you are eligible. The study team must confirm diagnosis, age, exclusions, available locations, and next steps.
What would I likely need to do?
You may need to use a device, app, or digital tool for a defined period. The listed study locations suggest that at least part of participation may involve a physical site. Ask whether some steps can be done remotely.
What should I check about data, monitoring, alerts, and daily use?
If the study uses a device, app, or digital tool, check what data is collected, who can access it, how often you need to use it, and what happens if the tool detects a concerning signal. For any mental health study, also ask who to contact if you feel worse, whether participation may affect current treatment, whether you can stop, and who confirms eligibility.
Will I need to travel or attend in-person visits?
The listed study locations suggest that at least part of participation may involve a physical site. Ask which sites are open, how many visits are expected, whether any steps can be done remotely, and whether travel costs or compensation are listed.
Who is behind this study?
This study is sponsored by Johns Hopkins University, which appears to be a university. If available, it can be useful to check the sponsor website, collaborators, investigator affiliation, and the official registry before deciding. HopeStage does not judge the quality of a sponsor or researcher, but helps you identify what to verify.
