What Is Group Therapy?

Group therapy is a form of psychotherapy in which one or two trained therapists work with a small group of clients — usually five to twelve — at the same time. People often picture it as a watered-down version of individual therapy: the same thing, but you have to share the hour. That's a misunderstanding. In group therapy, the group isn't a compromise. It's the active ingredient.

Why the group is the point

The psychiatrist Irvin Yalom, whose work shaped modern group therapy, described the group as a social microcosm. Over time, people tend to behave inside the group the way they behave outside it — the person who fears rejection holds back, the person who feels responsible for everyone starts caretaking. Those patterns then become visible and workable in real time, with immediate feedback from people who have no stake in pretending.

Yalom catalogued the "therapeutic factors" that make this work. A few of the most important:

• Universality — the relief of discovering you're not uniquely broken; others struggle with the same things.
• Interpersonal learning — seeing how you affect others and trying out new ways of relating.
• Cohesiveness — the sense of belonging and acceptance that makes change feel safe.
• Instillation of hope — watching others further along give you reason to believe change is possible.

What a session looks like

A typical group meets weekly for about 75 to 90 minutes with a consistent membership and a strong confidentiality agreement. Formats vary widely:

• Process groups focus on the here-and-now relationships in the room and the patterns they reveal.
• Skills groups (such as CBT or DBT groups) teach and practice specific tools for managing emotions, anxiety, or distress.
• Psychoeducational and themed groups organize around a shared issue — grief, trauma recovery, substance use, social anxiety.

In all of them, the therapist's job is to keep the space safe, draw out what's happening between members, and help people connect what they notice to life outside the room.

Who it helps

Group therapy has strong evidence behind it for depression, anxiety, trauma, grief, substance use, and especially difficulties that are interpersonal at their core, like social anxiety and chronic relationship problems. It tends to suit people who are ready to be seen by others and to learn from them; it's less appropriate in acute crisis, where stabilizing individual care usually comes first.

Because it's clinical treatment, group therapy is led by licensed professionals — psychologists, clinical social workers, counselors, or psychiatrists. If you think it might help, a good first step is asking a therapist or your doctor for a referral.

How it differs from T-groups and circling

Group therapy can look, from the outside, like other group practices — but it's the only one that's clinical treatment. A T-group is an experiential learning practice for growth, not therapy, and is usually facilitator-led rather than clinician-led. Circling is a relational awareness practice focused on present-moment connection. If you're seeking help for a mental-health condition, group therapy — not a T-group or circling — is the one designed for that.
