A student seeking help

Hi, all-
I am looking for law enforcement officers interested in participating in an online survey for a project designed to study the relationships among sleep behavior, nightmares, occupational stress, and social support. Participation will take approximately 30-35 minutes. After participating, you can be entered into a drawing for a $200 Visa gift card.
You can access the survey here:

I am a student in the PhD program of Clinical Psychology at CSPP, Los Angeles. I am studying to work with law enforcement officers and would greatly appreciate your help.
Thank you for your time.
