Group Therapy vs. Individual Therapy: Benefits and Differences

When people decide to seek therapy, one of the first questions they face is: should I see a therapist one-on-one, or would a group setting work better for me? Both are legitimate, evidence-based forms of psychotherapy – but they work in fundamentally different ways. Understanding those differences can help individuals make a more informed choice about their mental health care.

A brief history: how group therapy came to be

Group therapy has its roots in the early 20th century. It first emerged as a way to support tuberculosis patients in hospital settings, and was later used to treat soldiers experiencing emotional distress during World War II. At the time, the sheer number of people requiring psychological care made individual sessions impractical – there simply weren’t enough therapists to go around. What began as a cost-saving workaround, however, quickly revealed something unexpected: treating people in groups wasn’t just convenient, it was therapeutically powerful in its own right.

The formal organizational foundations of group therapy in the United States took shape in the 1940s, with the establishment of two separate interdisciplinary organizations by Samuel Slavson and Jacob Levy Moreno in New York City. After World War II, the field was further developed by figures including Irvin Yalom, whose approach to group therapy went on to have significant global influence. Today, group therapy is a recognized and rigorously studied form of treatment used for a wide range of mental health conditions.

What is group therapy, exactly?

Group therapy involves the treatment of psychological problems in a setting that includes two or more participants along with a therapist who facilitates the group. Participants interact with each other, share problems and concerns, and the therapist fosters an environment of mutual respect where members can strengthen self-understanding and improve interpersonal relationships. Sessions can vary widely in size and structure depending on the type of therapy being delivered. Most commonly, groups are small – typically five to eight members – and meet regularly around a shared concern or therapeutic goal.

Group therapy is not the same as a support group. While support groups are often peer-led, group therapy is conducted by a trained mental health professional who guides the process, monitors group dynamics, and delivers structured therapeutic interventions.

What is individual therapy?

Individual therapy is the treatment of psychological problems in a private setting where a therapist works one-on-one with a patient. The approach and process are tailored to the patient’s individual needs, with sessions focused on exploring problems and working on ways to alleviate symptoms. Approaches like cognitive-behavioral therapy (CBT), motivational interviewing, and dialectical behavior therapy (DBT) are commonly used in individual sessions. The therapist’s full attention is on one person, which allows for deep, personalized work at the client’s own pace.

Key differences between the two formats

The most obvious difference is structural: one format involves a single client and therapist, while the other brings multiple clients together. But the differences go deeper than just numbers.

The unique benefits of group therapy

Decades of research have identified specific mechanisms that make group therapy therapeutically effective. Psychiatrist Irvin Yalom formalized these in his influential framework of 11 therapeutic factors, several of which are unique to the group setting.

Universality: you are not alone

One of the core benefits of group therapy is the assurance that others share similar problems and struggles – reducing the sense of isolation that many people feel when dealing with mental health challenges. Discovering that others carry the same fears or shame can be profoundly relieving, and is often cited by participants as one of the most valuable parts of the experience.

Sharing in group sessions allows people to improve social skills, find healthier ways to express themselves, and build solidarity with others dealing with similar issues. Seeing how others cope, communicate, and work through difficulties offers a form of learning that simply isn’t available in one-on-one therapy. Interacting with others in the group setting helps members practice communication, empathy, and conflict resolution – skills that can enhance their relationships outside of therapy as well.

Altruism and mutual support

Receiving support from others is part of the therapeutic alliance that forms in groups, while giving support to others creates opportunities for growth and learning. Being helpful to fellow group members builds self-esteem and a sense of purpose – which can itself be therapeutic, particularly for those who have long felt burdensome to others.

Instillation of hope

When individuals join a group of people struggling with similar problems, they have the opportunity to witness change in others while also having their own progress acknowledged and celebrated by group members. This visibility of recovery and change is something that individual therapy, by design, cannot offer in the same way.

The unique benefits of individual therapy

Individual therapy offers its own set of advantages that group settings cannot always replicate.

Privacy and depth

Individual therapy allows clients to work through deeply personal issues in a private and confidential setting, with therapists tailoring treatment plans to specific needs and creating goals to track progress. For individuals dealing with trauma, abuse histories, or highly sensitive material they are not ready to disclose in a group, this level of privacy is essential.

Personalized pacing and flexibility

Individuals who can handle more focused and intense interventions may benefit from a quicker therapy pace, while those who need more time to adjust can work at a slower pace. Because a therapist can give undivided, personalized attention, clients can explore their issues more deeply without dealing with group dynamics or distractions.

Crisis response

Individual therapy is also the more appropriate setting for people experiencing acute mental health crises, including severe depression, active suicidal ideation, or early-stage trauma processing. The focused, one-on-one nature of the work allows for immediate and targeted intervention without the added complexity of managing group dynamics.

When group therapy may not be the right fit

Group therapy is not suitable for everyone. Research finds that both individual and group therapy are relatively equivalent in effectiveness across a large number of issues – but suitability depends on the individual. People who are highly introverted, acutely socially anxious, or in the midst of a serious mental health crisis may find the group setting overwhelming rather than helpful, at least initially. Personality conflicts within groups can also hinder progress for those who struggle with interpersonal trust. Additionally, some individuals simply find it difficult to open up in front of strangers, which limits their engagement with the therapeutic process.

Those dealing with very personal or complex trauma, or conditions requiring intensive one-on-one intervention, are often better served starting with individual therapy before transitioning to a group format.

What the research says about effectiveness

A randomized pilot study comparing individual and group therapy for university students with anxiety and depression found significant reductions in symptoms across both formats, with no significant difference in outcomes between them. A meta-analysis published in the Journal of Clinical Psychology found that group therapy was as effective as individual therapy for treating depression, with both leading to significant improvements in symptoms. Similarly, group CBT was found to be as effective as individual CBT for social anxiety disorder.

These findings don’t make one format superior to the other – they suggest that the right format depends on the individual’s needs, goals, and the nature of their concerns.

Combining both approaches

Many mental health professionals recommend a combined approach rather than treating it as an either-or decision. An individual may benefit from both the personalized attention of individual therapy and the community support of group therapy – therapists may recommend individual therapy for more intensive personal work and group therapy for ongoing support and maintenance. For conditions like substance use disorders, social anxiety, and grief, this combination has shown particular value. Individual therapy provides the safety needed for deep personal processing, while group therapy delivers the interpersonal learning and community connection that one-on-one sessions cannot replicate.

Choosing the right format

The choice between group and individual therapy ultimately depends on a person’s specific concerns, comfort level with disclosure, therapeutic goals, and practical considerations like cost. Individual therapy is ideal for deeply personal issues such as trauma or self-esteem, where a private and tailored approach is essential. Group therapy is highly effective for issues that benefit from peer support and shared experience, such as addiction, social anxiety, or grief. Neither format is inherently better – each serves a distinct purpose, and both are grounded in substantial evidence.

A good starting point is to speak with a mental health professional who can assess your needs and recommend the format most likely to benefit you – or a combination of both.

What do you think? If you were considering therapy for the first time, what factors would matter most to you – the privacy of one-on-one sessions, or the sense of shared experience that a group can offer? And do you think there are certain problems that are better worked through with the support of others who truly understand them from the inside?
