Which of the following is NOT a stage in Tuckman's 5 Stages of Group Therapy?

In Tuckman's model of group development, the five stages are forming, storming, norming, performing, and adjourning (or mourning in some variations). Each of these stages represents different phases that groups go through as they evolve and function together.

The forming stage involves initial orientation and getting acquainted among group members. The storming stage is characterized by conflict and competition as group members assert their opinions and roles. The norming stage emerges once the group begins to establish norms and resolve conflicts, moving toward collaboration. The performing stage reflects a time when the group effectively works toward its goals, leveraging the established relationships and norms, while the final stage, adjourning, pertains to the disbanding of the group after achieving its objectives.

The term "adapting" does not align with any of Tuckman's recognized stages and does not represent a phase that groups typically experience during their development. Thus, identifying "adapting" as not belonging to Tuckman's stages highlights a crucial understanding of group dynamics in therapy and other similar settings.
