In the Boston Model, which stage emphasizes clarification of differential and cohesive processes and group autonomy?

• A. Differentiation Stage
• B. Preaffiliation Stage
• C. Intimacy Stage
• D. Separation Stage

Answer: (A)

In the Boston Model, the stage that focuses on how the group functions and how individual differences fit with group unity is the Differentiation stage. This phase is about clarifying differential processes—how members differ, what each person needs, and how those differences influence group dynamics—along with cohesive processes, which are the norms, trust, and capacity of the group to work together effectively. It also emphasizes group autonomy, shaping how decisions are made, who has influence, and how the group can stay connected while allowing members to act as individuals. This stage sits after the initial orientation of Preaffiliation and before the deeper closeness of Intimacy, laying the groundwork for healthy cohesion and clear boundaries before the group moves toward deeper involvement or eventual separation.
