I am not the biggest professional volunteer, yet I've been around a while and pretty much lost track of how many studies I've done. As a former scientist and healthcare worker I rag on botched procedures to myself (and sometimes in public).
Rather than note only the negative, when soing is done right I should point it out so here goes:
Hands down, the way V. and A. does things is far superior to any where else I have been. Thumbs up here. Not that other places are bad (Quintiles is fine), it's that there is a reason V. and A. does not have to advertise much and has plenty of volunteers. Who else would think of offering compensation just for screening? Yet they do, and do not assume you have a bad nature.
Two thumbs up for this place which is expanding while other companies are scaling back.
I recently screened for the first time at vince. Overall good impression, but I had a couple of problems. They called me at 9 pm the night before screening to say the screening had been postponed a day. So an extra night in a hotel and a day wandering around kansas city took up the screening payment (which was bigger than expected. annoyingly, it's only a gift card, not a check.) Then when they were supposed to call me with the results, they didn't. Eventually, a day before check-in, I got through to somebody who said the study had been postponed. I still don't know if it is cancelled, or will be rescheduled, or if i'll have to rescreen, or what.
