During the initial stage of therapy, the group members get to know each during orientation and may be hesitant in participation. During this initial stage, the group members must determine a method of achieving their primary task (reason joined group) and establish a place that allows for comfort and gratification of being in group.

During the second stage of therapy the group members experiences conflict, ups and downs, the struggle for dominance, control, and power, and conflict with the group leader.

During the third stage of group, the members develop cohesiveness, take on a ownership of the group, and provide mutual support and work together. Conflict will emerge. However, now in an environment of cohesiveness, the struggle is not with dominance but with resistance.

During the termination phase, boundaries are diffuse (the process is not linear but is more like a spiral) and much is up to chance as no two groups are alike.
