A study was conducted several years ago covering a span of years by sociologists Sheldon and Eleanor Glueck from Harvard and they identified after all of this study four crucial factors in predicting children who were not delinquents. This was a multi-year study and it was found to be 90 percent accurate. They said these are the four essential factors to prevent delinquency, just purely from the observation of those worldly people. One, the father’s discipline, fair, firm and consistent. Two, the mother’s supervision in the home, knowing where the children are all the time, knowing what they’re doing and being available to them. Three, the parents unceasing affection demonstrated to each other and to the children frequently. And fourthly, the family's cohesiveness, time spent together.
