In this article
Individual, group, and online therapy each serve different needs. Learn how they differ in structure, cost, and who tends to benefit most from each.
Key Takeaways
- Individual therapy offers private, personalized care tailored to a single person's goals and history.
- Group therapy provides peer connection and shared experience, often at a lower cost per session.
- Online therapy can match the effectiveness of in-person care for many common concerns, with added convenience.
- No single format is universally superior — the right fit depends on your goals, preferences, and circumstances.
- Always consult a licensed mental health professional to determine which format suits your specific needs.
How Therapy Formats Differ
Mental health therapy is not one-size-fits-all. Three primary delivery formats — individual, group, and online sessions — each carry a different structure, dynamic, and set of practical considerations. Understanding those differences helps people make more informed decisions about where to start or how to continue their care.
If you're still weighing whether professional support makes sense for you at all, the article Signs You Might Benefit from Talking to a Mental Health Professional outlines common signals worth considering. Once you've decided to pursue therapy, choosing the right format is the natural next step.
| Individual Therapy | Group Therapy | Online Therapy | |
|---|---|---|---|
| Session structure | One client, one therapist | 5–15 clients, 1–2 therapists | One-on-one or group via video/phone |
| Typical cost per session | Higher — most expensive format | Lower — cost shared across members | Varies; often comparable to in-person |
| Privacy level | Fully private | Semi-private; shared setting | Private if home environment allows |
| Peer connection | None — therapist only | Core feature of the format | Possible in virtual group formats |
| Scheduling flexibility | Moderate — varies by provider | Fixed group schedule | High — broader availability |
| Evidence base | Extensive for most conditions | Strong for many conditions | Growing; comparable for common concerns |
| Best suited for | Complex or sensitive personal issues | Shared challenges; skill-building | Access barriers; mild-moderate concerns |
Individual Therapy: Personalized and Private
Individual therapy — sometimes called one-on-one or talk therapy — involves a single client working directly with a licensed therapist. Sessions typically run 45 to 60 minutes and are structured around that person's specific goals, history, and presenting concerns.
This format allows for deep exploration of personal experiences without the social dynamics of a group. It is well suited for people dealing with trauma, complex relationship patterns, or issues they aren't yet comfortable discussing in a shared setting. Evidence-based approaches such as cognitive behavioral therapy (CBT) are frequently delivered in this format. For a thorough overview of how CBT works in practice, see The Complete Picture of Cognitive Behavioral Therapy.
The primary trade-off is cost: individual sessions tend to be the most expensive per visit, and availability of in-network providers can vary considerably by location.
Group Therapy: Shared Experience and Peer Support
Group therapy brings together a small number of participants — typically 5 to 15 — under the guidance of one or two licensed therapists. Sessions may be structured around a shared diagnosis, life experience, or skill-building curriculum (such as dialectical behavior therapy skills groups), or they may be more open-ended and process-oriented.
Research consistently shows that group therapy produces meaningful outcomes for a range of conditions, including depression, anxiety, substance use disorders, and grief. One of its core therapeutic mechanisms is universality — the recognition that others share similar struggles, which itself can reduce isolation and shame.
Group Therapy Is Not a Support Group
Group therapy led by a licensed therapist is a clinical treatment — not the same as a peer support or self-help group, though both can be valuable. Clinician-led groups follow structured therapeutic approaches and are often covered by health insurance in the same way individual sessions are. Ask a provider or insurer about your specific coverage.
From a practical standpoint, group sessions are generally less expensive per session than individual therapy. However, scheduling is typically fixed, and the format requires a degree of comfort with sharing in a semi-public setting. Group therapy is not a lesser alternative to individual work — for many people and many conditions, it is the preferred approach.
Online Therapy: Access and Flexibility
Online therapy — also called teletherapy or telehealth counseling — delivers therapeutic services via video call, phone, or sometimes asynchronous messaging. It can replicate either individual or group formats in a virtual environment.
A growing body of research suggests that video-based individual therapy produces outcomes comparable to in-person care for many common presentations, including depression, anxiety, and PTSD. The American Psychological Association has noted that telepsychology, when conducted appropriately, can be an effective mode of service delivery.
The practical advantages are significant: no commute, greater scheduling flexibility, and broader geographic reach — particularly valuable for people in rural areas or those with mobility limitations. If you're curious about what the first appointment actually looks like in either format, What Happens During a First Therapy Appointment offers a realistic preview.
Limitations do exist. Poor internet connectivity, lack of a private space at home, and the absence of physical co-presence can present genuine barriers for some individuals. Online therapy may also be less appropriate for people experiencing severe psychiatric symptoms or crisis-level distress, who often require in-person evaluation and support.
