Individual vs Group Therapy: Pros, Cons, and How to Choose

The Short Answer

Individual therapy provides one-on-one attention from a therapist, allowing deep exploration of personal issues with complete confidentiality. Group therapy brings together several people (typically 5 to 12) with similar concerns, facilitated by one or two therapists, and uses the group dynamic itself as a therapeutic tool. Individual therapy offers personalized treatment and privacy. Group therapy offers peer support, normalization, and the opportunity to learn from others' experiences. Both are evidence-based, and for many conditions, group therapy is as effective as individual therapy while costing significantly less.

Quick Comparison

How Individual Therapy Works

Individual therapy is the most familiar format. You meet with a therapist one-on-one, typically for 45 to 60 minutes each week. The session is entirely devoted to your concerns, your history, and your treatment goals.

The therapist selects and applies evidence-based techniques tailored to your specific diagnosis, symptoms, personality, and preferences. If you have PTSD, the therapist can use trauma-focused CBT or EMDR designed for your particular experiences. If you have depression, they can target your specific cognitive patterns and behavioral withdrawal. Treatment is individualized at every level.

The therapeutic relationship, the alliance between you and your therapist, is itself a powerful agent of change. Research consistently identifies the quality of this relationship as one of the strongest predictors of therapy outcomes, regardless of the specific techniques used. In individual therapy, this relationship receives undivided attention.

Individual therapy provides complete confidentiality. What you share stays between you and your therapist (with standard exceptions for safety). This privacy allows exploration of deeply personal topics: sexual concerns, shame-laden experiences, family secrets, and thoughts you have never shared with anyone.

The therapist can adjust the pace, depth, and approach from session to session based on how you are responding. If a particular technique is not working, they can pivot immediately. If a crisis arises, the entire session can address it.

Individual therapy is effective across virtually all mental health conditions. It is the most studied therapy format and forms the foundation of most clinical guidelines.

How Group Therapy Works

Group therapy involves a trained therapist (or two co-therapists) facilitating a session with multiple clients who share similar concerns. Groups may be organized around a diagnosis (depression, anxiety, substance use), a life circumstance (grief, divorce, caregiving), a skill set (DBT skills, social skills), or a therapeutic approach (psychodynamic process groups).

Groups typically follow one of two structures:

Psychoeducational/skills groups follow a curriculum. Each session covers a specific topic or skill, with discussion and practice. DBT skills groups, anger management groups, and many substance use groups follow this format. These groups have a clear beginning and end date, and members join at the start.

Process groups are less structured and focus on interpersonal dynamics within the group itself. Members share experiences, provide feedback, and explore how their patterns play out in real time with the other group members. These groups may be ongoing, with members joining and leaving at different points.

The therapeutic power of group therapy comes from several unique factors identified by Irvin Yalom, a pioneer in group therapy research:

Universality: Discovering that others share your struggles reduces isolation and shame. Hearing someone else describe exactly what you experience can be profoundly validating.

Altruism: Helping others in the group builds self-esteem and a sense of purpose. People who feel broken often discover they have valuable insights to offer.

Interpersonal learning: The group is a microcosm of the outside world. Patterns that create difficulties in relationships (withdrawal, people-pleasing, aggression, avoidance) emerge naturally in the group and can be addressed in real time.

Modeling: Watching others cope with challenges, express emotions, or assert boundaries provides concrete examples that can be applied in your own life.

Group cohesion: The sense of belonging that develops in an effective group is itself therapeutic, particularly for individuals who feel disconnected or alone.

Research supports group therapy's effectiveness for a wide range of conditions. For depression, meta-analyses show that group CBT produces outcomes comparable to individual CBT. For substance use disorders, group therapy is a standard component of treatment. For social anxiety, group therapy offers the additional advantage of built-in exposure to social situations.

Key Differences

Attention and Personalization

In individual therapy, you receive the therapist's undivided attention for the entire session. Every intervention is designed for you. In group therapy, attention is distributed among all members. You may speak for only a portion of the session, and interventions address the group's needs rather than your specific situation.

However, listening to others' experiences and the therapist's responses to them can be just as therapeutic as direct attention. Many group members report benefiting as much from observing others' work as from their own.

The Social Element

Individual therapy is a private dyadic relationship. Group therapy is inherently social. For individuals whose difficulties are primarily interpersonal (trouble maintaining relationships, social anxiety, conflict patterns), group therapy provides a live laboratory for practicing new ways of relating.

For individuals whose concerns are deeply personal and not primarily relational (processing a specific trauma, addressing intrusive thoughts), individual therapy's privacy may be more appropriate.

Cost Effectiveness

Group therapy typically costs one-third to one-half of individual therapy per session. Because groups meet for longer sessions and the cost is distributed among members, the therapist can offer a lower rate while still providing extended treatment time. For individuals without insurance or with limited financial resources, group therapy can make ongoing treatment accessible.

Cost Comparison in Detail

The cost difference between individual and group therapy is significant. Individual therapy sessions typically range from $100 to $250 per session, depending on your location, the therapist's credentials, and whether you are using insurance. Group therapy sessions typically cost between $15 and $50 per session out-of-pocket, though some groups charge up to $80. This means that for the cost of one individual session, you could attend two to five group sessions, each of which provides 60 to 120 minutes of therapeutic contact.

Insurance Coverage

Most insurance plans cover group therapy, though the specifics vary. Group therapy is billed under its own CPT code (90853), which is distinct from individual therapy codes. Many plans cover group therapy with the same copay structure as individual therapy, meaning your out-of-pocket cost may be the same for either format. Some plans cover group therapy with a lower copay. It is worth calling your insurance company to ask specifically about group therapy coverage, as it is sometimes listed under a different benefit category. If you are paying out of pocket, the cost advantage of group therapy is substantial.

Online Group Therapy

Online group therapy has grown rapidly as a treatment option, particularly since 2020. Telehealth platforms now offer group therapy sessions via video conferencing, making groups accessible to people in rural areas, those with mobility limitations, or anyone who prefers the convenience of participating from home. Research on online group therapy is still emerging, but early studies suggest that virtual groups can produce outcomes comparable to in-person groups for conditions like depression and anxiety. Online groups follow the same structure as in-person groups — regular meeting times, consistent membership, and a trained facilitator — with the added benefit of eliminating geographic barriers.

Confidentiality

Individual therapy offers legally protected confidentiality. Group therapy asks members to maintain confidentiality, but this is based on group agreements and trust rather than legal obligation. While breaches are uncommon in well-run groups, the risk is not zero. For individuals dealing with extremely sensitive material (such as certain legal situations, stigmatized conditions, or safety concerns), this is an important consideration.

Normalization vs Individualization

Group therapy excels at normalization. Discovering that you are not alone in your experience can reduce shame and isolation more powerfully than any individual therapist's reassurance. When a group member says "I feel that too," it carries a different weight than when a therapist says "That is common."

Individual therapy excels at individualization. Your specific history, cognitive patterns, and life circumstances receive focused attention. Treatment can be precisely calibrated to your needs.

Which Is Better for You?

Individual therapy may be the better choice if:

• You are dealing with complex trauma, abuse, or highly sensitive material
• You need a specific evidence-based protocol (such as ERP for OCD or EMDR for PTSD)
• You have never been in therapy and want to build comfort with the process
• You have difficulty sharing in groups or have a condition that makes groups challenging
• Your concerns are highly specific and would not be shared by a typical group
• You need flexibility in scheduling and session focus

Group therapy may be the better choice if:

• Your difficulties are primarily interpersonal (relationship patterns, social anxiety, isolation)
• You would benefit from peer support and shared experience
• You want to build social skills in a safe environment
• Individual therapy has helped but you need a different kind of growth
• Cost is a significant barrier to treatment
• You are in recovery from substance use and benefit from community support
• You want to practice skills (such as DBT) in a structured group setting

Can Individual and Group Therapy Be Combined?

Yes, and combining them is common and often recommended. Many treatment models explicitly call for both.

DBT is the clearest example: the standard DBT program includes weekly individual therapy sessions alongside weekly skills group sessions. The individual sessions address personal crises and apply skills to specific situations, while the group teaches and practices the core skills.

For substance use disorders, a combination of individual therapy (addressing underlying psychological issues) and group therapy (providing community support and accountability) is standard practice across many treatment settings.

A practical approach is to begin with individual therapy to establish a diagnosis, build a therapeutic relationship, and develop initial stability. Once foundational work is done, group therapy can be added to provide peer support, interpersonal practice, and a broader perspective. Some individuals eventually transition from individual to group therapy as their primary format, reserving individual sessions for periodic check-ins.

How to Choose

Identify your primary need. If you need personalized treatment for a specific condition, start with individual therapy. If you need connection, support, and interpersonal growth, group therapy deserves consideration.

Consider the practical factors. Cost, schedule, availability, and insurance coverage all matter. Group therapy may be the pragmatic choice that allows you to receive treatment you could not otherwise afford.

Ask your therapist. If you are already in individual therapy, ask your therapist whether a group might complement your work. They can often recommend appropriate groups and explain how the combination would benefit you.

Try it. Many people are apprehensive about group therapy and discover it is far more comfortable and valuable than they anticipated. Most groups allow a trial period, and the facilitator can help you determine fit.

Evaluate the group carefully. Not all groups are equal. Ask about the therapist's qualifications, the group's structure and rules, how confidentiality is handled, and what the screening process is for new members. A well-run group with clear boundaries is a different experience from a poorly facilitated one.

The Bottom Line

Individual and group therapy are complementary formats, not competitors. Individual therapy provides personalized, private treatment with undivided therapeutic attention. Group therapy provides peer support, normalization, and a unique opportunity for interpersonal learning. For many conditions, both formats produce comparable outcomes. The best choice depends on your specific concerns, interpersonal needs, and practical circumstances, and combining both is often the most comprehensive approach.
