As a mother of 2 teenage girls, I'm particularly interested in educated (and protecting) them on this subject. Faith based groups are mentioned above. Both of my girls are active in their faith especially by attending church sponsored mission trips (over seas) and extended out of town trips. One thing I've tried to instill in them, besides awareness, is for them to not become a target when participating in the activities, especially away from home. They need to be particularly aware and not have a false sense of protection by being with the church. Letting their guards down with a false sense of protection provides more opportunity for those looking/focusing on their "targets". Just a thought...
