One alternative may be the influence of religion. Even if the child did not have a secure attachment as a child, some may grow older and become anti social. However, when some go into religion (which acts very much as a supportive mother would) they can regain the positive reinforcement of making connections and become more social and friendly.
This is a good thought, darthtater. I personally know a boy who grew up in a troubled family who had a lot of issues. He abused drugs and did not relate well to others. However, he joined a church community two years ago and he is now more outgoing and willing to relate to others. The transformation is remarkable. Although a change this stark is not very common, it is interesting to note the tremendous effect religion had on this young man. It is amazing to see people make changes like this so late in their lives, since personality is usually shaped and solidified early in life.
