What Is Group Therapy?

Group therapy is a form of psychotherapy where one or more trained therapists work with a small group of people at the same time, usually anywhere from 5 to 15 participants. Sessions are structured around a shared theme or condition, and progress comes not just from the therapist, but from the interaction between group members — hearing others' experiences, giving and receiving feedback, and practicing new behaviors in a safe, supported setting.

It's not group therapy just because multiple people are in a room. Effective group therapy is facilitated, has clear goals, and follows an established therapeutic model.

Why Group Therapy Works

• Reduces isolation. Many people going through anxiety, addiction, or grief feel like no one else understands. A group immediately breaks that illusion.
• Real-time practice. For social anxiety especially, a group is live exposure therapy — a genuine social situation where new skills can be tested safely.
• Peer accountability. Group members often push each other toward honesty and consistency more effectively than a therapist working alone can.
• Cost-effective and often more consistent. Weekly group sessions are usually more affordable than equivalent individual therapy hours, which means people are more likely to stick with treatment long enough for it to work.

Types of Group Therapy

Not all group therapy looks the same. The type matters — a program built for addiction recovery looks very different from one built for anxiety or grief. Here are the main types used in clinical settings today:

Cognitive Behavioral Group Therapy (CBGT)
Structured around identifying and reframing unhelpful thought patterns, practiced live with peer feedback. Commonly used for anxiety disorders, depression, and phobias.

Dialectical Behavior Therapy (DBT) Groups
Focused on building four core skill sets — mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness. Originally designed for borderline personality disorder, DBT groups are now widely used for emotional dysregulation, self-harm, and anxiety.

Psychoeducational Groups
Less about processing emotions, more about teaching — what a condition actually is, why the body and mind respond the way they do, and practical tools to manage it. Often the entry point for people new to treatment.

Support Groups
Less clinical, more experience-based. Members share what they're going through, and the value comes from mutual understanding rather than a structured curriculum. Common in addiction recovery (like 12-step models) and grief support.

Interpersonal Process Groups
Focused on how members relate to one another in real time, using those dynamics as a mirror for patterns that show up in the person's life outside the group.

Expressive and Creative Therapy Groups
Includes dance/movement therapy and music therapy — approaches that let people process and express emotion without relying purely on verbal skills. Especially effective for people (including many young people with social anxiety) who find it hard to open up through talking alone.

Family and Multi-Family Groups
Bring family members into the therapeutic process together, useful when the condition being treated — addiction, eating disorders, adolescent mental health issues — is deeply tied to family dynamics.

Choosing the Right Type

The right type of group depends entirely on what's being treated and how the person engages best. Someone with social anxiety may benefit most from a blend — CBGT for the thought patterns, DBT for emotional regulation, and expressive therapies like dance or music to build confidence outside of verbal performance. Someone in addiction recovery may need a different mix entirely, often layering support groups with family sessions.

This is where the quality of the treatment centre matters. A program that only offers one type of group therapy will only reach people who respond well to that one format — and a lot of people don't.

Calida Rehab stands out for exactly this reason: rather than running a single group format, they combine DBT, structured group therapy, dance movement therapy, and music therapy into one integrated program. That range means a person who shuts down in talk-based groups still has a real entry point into treatment through movement or music, instead of being written off as "not ready" for therapy.

The Bottom Line

Group therapy isn't a lesser version of individual therapy — for many conditions, it's the more effective one, precisely because it happens in the presence of other people. The key is finding a program that offers the right combination of group types for the specific condition being treated, rather than a one-size-fits-all format.
