The open time-extended group, run by multiple counselors, adds a facilitating dimension to the counseling function--a dimension that exemplifies the concepts of self-growth and self-actualization by first providing the atmosphere for the client and then by allowing him to progress at his own rate and to a depth which he determines. An open group differs from a closed group in the following ways: (1) no set size, (2) anyone can come, (3) participant behavior determines what is to be focused upon, when it will be focused on and how long the focus will remain there; and (4) time is practically limited to three to four hours, theoretically it should be unlimited. Varying group structure results in changing the dynamics of groups. Destructiveness or the tearing down of defenses without providing for new replacement patterns is more likely in open groups. There is also a significant amount of experimentation as well as creativity observed in open groups. Training values include the opportunity to observe co-workers to see how they handle certain situations. In addition, counselors working with open groups are esentially "forced" to develop spontaneity and flexibility in style. (Author/KJ)
