This question came up in my college class some months back. I did ask my teacher about conduct disorders and this generation, vs. the 70's and before. 1) Why did we not seem to have this trend as kids? I remember being parented in do or die fashion. and school was not the school of today as in truant, gangs, attitude, drugs, etc. Was it just that kids were not DIAGNOSED and studies were few back then? Was it diet related? Parenting change related? Divorce rate related? I know I know. I am probably asking something like what came first the chicken or the egg! But anything you have read or heard in studies etc as to WHY would probably help me understand my difficult child's behavior better. By the way, teacher told me that years and years ago, conduct disorders have always been "around" just never diagnosed and kids who had them turned to alcoholism or such to cope, instead of therapy or medications.
