Macro-skills involve planning and organizing the overall flow of a group session—setting goals, selecting activities, timing, transitions, and creating a safe, inclusive structure. Designing the session fits this because it covers the big picture: what the session aims to achieve, how the activities are arranged to move participants toward those goals, how time is allocated, and what norms or contingencies are put in place for smooth progression. The other options are micro-skills—specific, moment-to-moment techniques used within a session to support interaction, such as listening attentively, restating or clarifying what someone said, or mirroring nonverbals. These enhance engagement and understanding, but they operate within the designed structure rather than constituting the overall design itself. So, session design is the macro-skill because it shapes the entire facilitation process.

The main idea here is group cohesion—the sense of belonging, acceptance, and mutual support that grows when members feel connected to the group. When a group works well, members trust one another, feel safe to share, and support each other, creating a supportive system that sustains participation and growth. Universality involves recognizing that others share similar experiences, which can reduce isolation, but it doesn’t by itself establish the ongoing sense of belonging and mutual backing that cohesion describes. Interpersonal learning is about understanding how we relate to others and what those interactions reveal about ourselves, not the shared sense of belonging. Catharsis refers to emotional release, not the sustained feeling of unity and support. So the SAMPLEbest fit for fostering belonging and support is cohesion.

Coleadership means two qualified facilitators share planning, monitoring, and intervention during a group, so responsibilities and emotional labor are distributed rather than resting on one person. That shared load lowers the risk of burnout because each leader can step back when needed, problem-solve together, and provide mutual support. It also enhances safety because two sets of eyes are monitoring dynamics, boundaries, and potential crises, making it easier to notice warning signs, intervene promptly, and debrief after challenging moments. In open groups, coleadership is especially helpful. When new members join or others leave, two leaders can orient them, maintain a consistent process, and handle transitions smoothly, which reduces disruption and protects safety. The idea that it increases burnout or has no impact isn’t supported by how shared leadership works in practice, and the notion that it shouldn’t be used for open groups misses the ways two leaders can maintain continuity and safety through turnover.

Establishing behavior expectations and group norms at the outset. When a facilitator lays out rules like no smoking and no cursing in the first session, they’re setting boundaries that create a safe, predictable environment and outline what conduct is acceptable. This helps reduce ambiguity, prevents conflicts, and supports respectful interaction, which is essential for trust and productive group functioning. Ambivalent transference describes mixed feelings toward the facilitator, not a procedural rule. Blocking is about interrupting or restricting participation, a specific intervention rather than a general guideline. Scapegoating is a group dynamic where blame is placed on one member, not about establishing norms. So the scenario best fits setting ground rules.
