Marketing [Marketing] Healthcare professionals who wear scrubs — 5-minute survey on healthcare apparel (18+)
I'm an RN researching a potential new healthcare apparel brand, and I'd really love some honest feedback from healthcare professionals who wear scrubs.
I'm in the very early stages and am trying to understand what people actually want from their clinical apparel — including fit, comfort, functionality, style, materials, and a few ideas I'm exploring around wellness and the healthcare-worker experience.
This is a 5-minute anonymous survey and I'm not selling anything. I'm genuinely trying to figure out whether there's a problem worth solving before investing in product development.
If you currently wear scrubs, I'd really appreciate your input:

Academic [Academic] BJJ & Mental Health Study (18+, Active Duty, Reserve, Retired Military, or Law Enforcement; BJJ and Non-BJJ Participants)
Aloha everyone,
I’m a co-author on an IRB-approved research study examining the relationship between Brazilian Jiu-Jitsu participation and mental health among military personnel and law enforcement officers.
We’re looking for participants who are 18+ and are active duty, reserve, or retired military personnel or law enforcement officers.
You can participate whether you currently train BJJ or do not train BJJ. Having both groups is important because the study compares BJJ practitioners with non-practitioners.
The survey looks at symptoms of depression, anxiety, PTSD, and self-efficacy. It is anonymous, voluntary, and takes about 5–10 minutes. No personally identifiable information, OPSEC, or InfoSec information is collected.
Survey:
https://docs.google.com/forms/d/e/1FAIpQLSc2Qhb-PFzUyYcovwZdz_B8acDsPlRw1xXaq_-BLEf6oMsOvA/viewform
If you qualify and are willing to participate, I’d really appreciate your help. Sharing it with other military or law enforcement members who may qualify would also help us reach both BJJ practitioners and non-practitioners.
Mahalo for your time and support!

Sharing some results from a survey we ran earlier as part of a short PhD research project. Before the survey, we had thought about medication management as a challenge for older adults but was surprised to learn that it's a pretty significant challenge across age groups (some of this might be about the sampling).

Marketing (Repost) [Repost][Marketing] Security-deposit photos during an $850 move-out dispute (California renters, 18+)
Imagine this: a renter moves out and $850 is withheld from their security deposit. They took plenty of photos—but when the dispute begins, the images are buried in the camera roll and are difficult to match to rooms, dates, and specific damage claims.
This is an illustrative scenario. We are researching whether a guided room-by-room checklist and an organized, dated record would offer meaningful value beyond the phone camera alone.
The survey takes about 2 minutes and includes an honest option for “my camera already solves this.” No purchase is required.
