Wow, that would have to be my greatest fear as a parent. I would like to offer you my ideas, although I am not a Psychologist, but I am a parent and a teacher with over 30 years experience with kids. I believe that the best way to avoid such a horrible outcome would include, really know your child, share his or her interests, get to know what his or her interests are. Be aware of children who follow family pressures to play Basketball, as it runs in the family. Be interested in what your child is doing, share his or her successes AND failures. Obviate the failures as a necessary part of learning we all fail, but we need to capitalize on these failures and avoid similar mistakes in the future. Know your child's friends, who are they mixing with? Who are they trying to mix with? How successful are they really at mixing with those they like? Is your child always in doors? Does he or she go out and play? Do they stay indoors by choice? If it is by choice what can you do to get them out and about? If it is not their choice then why are they staying in? Who are they speaking to on Face Book? Are they positive discussions or comments that are derogatory and negative? Do not take the "Yeah all is good I am doing fine" comments as Gospel, but you are going to have to be a little sneaky, kids love their privacy. Hey, that is OK as you are the Mum or the Dad and this gives you special powers because nothing is more important to you than the welfare of your child, remember that.
This is all off the top of my head, but I hope it helps.
