Key Takeaways
Option A
Individual Therapy
Private, personalised support tailored entirely to you.
Best for: People who want a confidential, one-on-one space to work through personal issues at their own pace.
Option B
Group Therapy
Shared healing through collective experience and peer connection.
Best for: People who benefit from knowing others share their struggles, and who want to build interpersonal skills alongside individual growth.
If you're navigating trauma, abuse history, or deeply personal disclosure
Individual Therapy
Sensitive or highly personal material is best explored in a confidential, one-on-one setting where the pace is entirely yours.
If you're managing social anxiety, loneliness, or relationship difficulties
Group Therapy
The group setting itself becomes a practice ground for real-world connection and communication — something individual sessions cannot fully replicate.
If cost or access is a significant barrier
Group Therapy
Group sessions are typically more affordable and are often available through community mental health services, making access broader.
If you want deep, tailored focus on a specific diagnosis or goal
Individual Therapy
Individual sessions allow a therapist to build an in-depth understanding of your unique situation and adapt the treatment approach accordingly.
If you want both personalised insight and peer connection
Individual Therapy
Many clinicians recommend starting individually to build a foundation of trust and self-awareness before or alongside group participation.
What Each Format Actually Involves
When people picture therapy, they often imagine a single person talking with a therapist in a private room. That's individual therapy — and it's the most common format. But group therapy is equally legitimate and, for many people, equally or more effective.
In individual therapy, you meet one-on-one with a licensed mental health professional. Sessions typically run 45–60 minutes and are focused entirely on your concerns, history, and goals. The therapist adapts the conversation — and the therapeutic approach — to suit you specifically.
In group therapy, a trained therapist facilitates sessions with several participants, usually between 5 and 15 people. Groups are often organised around a shared theme — grief, anxiety, addiction recovery, or life transitions, for example. The therapist guides discussion, but peer interaction is a central part of the therapeutic process itself.
It's worth noting that group therapy is distinct from support groups. Support groups (such as community peer circles) are typically peer-led and not clinically structured. Group therapy is professionally facilitated and follows evidence-based frameworks. For a broader look at therapy types, see the Types of Therapy hub.
| Criterion | Individual Therapy | Group Therapy |
|---|---|---|
| Session structure | One client, one therapist | Multiple clients, one facilitator |
| Privacy level | Fully confidential | Shared with group members |
| Personalisation | Entirely tailored to you | Shared focus across participants |
| Typical cost | Higher per session | Generally more affordable |
| Peer connection | Not a component | Central to the process |
| Interpersonal skill practice | Discussed, not practised live | Practised in real time |
| Pacing | Set by your needs alone | Shared with group needs |
| Best suited for | Deep personal or trauma work | Social, relational, or shared challenges |
The Real Differences in Experience and Outcome
The most significant practical difference is privacy. Individual therapy is entirely confidential between you and your therapist (within legal limits). In a group setting, you share space with peers — and while professional confidentiality norms are established, the dynamic inherently involves more people knowing your story.
For some, this feels vulnerable in a productive way. Research consistently suggests that hearing others articulate shared experiences can reduce the isolation many people feel around mental health struggles. The clinical term for this is universality — the therapeutic realisation that you are not alone.
Individual therapy, however, allows for depth that a group cannot always match. A therapist can spend an entire session exploring one specific memory, relationship pattern, or emotional response — something that simply isn't possible when session time is shared.
~80%
Effectiveness rate for group therapy
Meta-analyses have consistently found group therapy produces meaningful outcomes for a broad range of conditions, with effectiveness broadly comparable to individual therapy for many presentations.
5–15
Typical group therapy participants
Most professionally facilitated therapy groups maintain small membership to allow meaningful participation and therapist oversight for each person.
There's also the question of interpersonal learning. If your challenges are rooted in how you relate to others — conflict avoidance, fear of judgment, difficulty trusting — group therapy offers a live environment to notice and work through those patterns. That's a unique benefit individual sessions can describe but not replicate.

Practical Factors: Access, Cost, and Fit
Cost is a real consideration. Individual therapy sessions in the US typically range from $100–$300 per hour without insurance, though sliding-scale options and insurance coverage can reduce this significantly. Group therapy is generally more affordable per session, and many community mental health centres offer it at low or no cost.
Availability matters too. In areas with limited mental health providers, group therapy may be more accessible — particularly through hospitals, community organisations, or structured programmes.
A Note on Special Populations
Children, adolescents, older adults, and individuals managing complex trauma or co-occurring conditions may have specific needs that influence which format is appropriate. If you or someone you care for falls into one of these groups, it's especially important to consult a qualified mental health professional rather than relying on general guidance. They can assess your circumstances and recommend the most suitable approach.
When thinking about fit, consider your comfort with disclosure and your primary goals. If you're just beginning to explore therapy and feel unsure where to start, our guide on questions worth asking before you start therapy can help you clarify what you're looking for before your first session.
It's also worth knowing that the two formats aren't mutually exclusive. Many people attend individual sessions while also participating in a group — using each to reinforce the other. A therapist can help you decide whether that combination makes sense for your situation.
