Group therapy is the most common modality in addiction treatment. Quality facilitation determines whether groups are transformative or time-filling.

Types of groups

Process groups: sharing experiences and receiving feedback. Psychoeducation: teaching about addiction, coping, triggers. Skills groups: practicing specific techniques (CBT, DBT skills). Step study: 12-step focused. Specialty groups: trauma, grief, relationships, gender-specific.

Facilitation best practices

Establish and enforce group norms. Balance participation (draw out quiet members, contain dominant ones). Model appropriate self-disclosure. Process group dynamics in real-time. Create safety through consistency and boundaries.

Common mistakes

Allowing cross-talk to become confrontational. Letting one person dominate. Using groups as lecture rather than interactive process. Failing to process emotional material that arises. Groups that are too large (8-12 is optimal).
