This study was concerned with the differences between two types of prisoners on a personality dimension and differences between these prison groups an a non-prison population. The impetus for this study stemmed from the development of a new test designed to scientifically measure the Freudian concept of the personality structures, the id, ego, and superego.

The purpose of this study is to get some concrete evidence that group principles can be applied to church groups in an effective manner. The more immediate purpose is to improve the relations in the individual classes so that they will have a feeling of belongingness, relatedness, or close affiliation. It is the purpose of this experiment to help these individuals find the fulfillment of their personal needs that can be supplied in the Sunday School class.
