Ask most people what therapy looks like and they’ll describe one couch, one therapist, and a box of tissues on the side table. Mention group therapy and you usually get a wince. Talk about my problems in front of strangers? On a weeknight? No thanks.
That reaction makes sense. Opening up is hard enough with one trained professional, let alone six or seven people you’ve never met. Still, group therapy is one of the best-studied formats in mental health care, and it keeps showing up in the research as a real option rather than a budget version of “real” therapy. For many people it ends up being the part of their healing they didn’t expect to need.
This guide walks through what group therapy is, what the evidence says, why talking with strangers can help in ways a one-on-one session can’t, and what to look for if you’re in California and thinking about trying it. No sales pitch. Just what you’d want to know before you sign up for anything.
What group therapy is (and what it isn’t)
Group therapy is a form of psychotherapy where a small group of people, usually somewhere between five and ten, meet regularly with one or two trained clinicians. Most outpatient groups meet once a week for 60 to 90 minutes. Some run for a set number of weeks with a clear curriculum. Others are ongoing, with members joining and leaving over time.
It helps to separate it from a few things it gets confused with.
It’s not the same as a support group. Peer support groups, like many 12-step meetings or hospital-run caregiver circles, can be wonderful. But they’re usually led by volunteers or peers, and the goal is mutual encouragement. A therapy group is led by a licensed clinician who screens members, sets agreements, watches how people interact, and steers the conversation toward change. That clinical structure is the difference.
It’s not a class. Some groups do teach skills, like managing anxiety or communicating in a relationship. But even skill-based groups lean on discussion, practice, and feedback between members. You’re not just taking notes.
It’s not group confession. Nobody is going to make you tell your whole story on day one. Good facilitators expect people to listen for a while before they share much, and they treat that as a normal part of the process.
Broadly, groups fall into two styles. Skills or psychoeducational groups focus on learning specific tools, often drawn from approaches like cognitive behavioral therapy (CBT) or dialectical behavior therapy (DBT). Process groups focus more on what happens between members in real time: how you react when someone disagrees with you, who you tend to rescue, when you go quiet. Plenty of groups blend the two.
Does it actually work? What the research says
Short answer: for a wide range of concerns, yes, and about as well as individual therapy.
The most cited work here comes from Gary Burlingame, a psychology professor at Brigham Young University who has spent decades studying group treatment. In 2016, his team published a meta-analysis that looked only at studies comparing group and individual formats directly, 67 of them. When the treatment, the patients, and the amount of therapy were comparable, the two formats produced equivalent outcomes. The American Psychological Association has since reported Burlingame’s summary of that work bluntly: across multiple disorders, the research found no meaningful difference between the two.
That finding wasn’t a one-off. Earlier meta-analyses going back to the 1990s pointed the same way, and disorder-specific reviews have found group treatment effective for depression, panic disorder, social anxiety, and more. The American Group Psychotherapy Association (AGPA) has started describing group as a “Triple E” treatment: effective, equivalent to individual therapy for many conditions, and efficient, because one clinician can help more people in the same hour.
What about online groups, which is how a lot of Californians attend now? The evidence is younger but encouraging. A 2018 systematic review in the Journal of Telemedicine and Telecare looked at video-based group treatment and found it feasible, with outcomes similar to in-person groups and high satisfaction among participants. The same review noted a small drop in the therapeutic alliance in some studies, and called for more rigorous trials. In other words: online groups appear to work, and the research community is still learning how to run them best.
Two honest caveats. First, “equivalent on average” doesn’t mean equivalent for every person. Some people do better one-on-one, at least at first. Second, quality matters. The research supports well-run groups with trained leaders, not any gathering that calls itself group therapy.
Why talking with strangers can help
If you’ve never been in a group, the idea that strangers could help you heal might sound strange. Psychiatrist Irvin Yalom, whose textbook The Theory and Practice of Group Psychotherapy (co-written with Molyn Leszcz) is still standard reading for group therapists, spent years asking group members what actually helped them. He organized the answers into a set of “therapeutic factors.” A few of them explain most of what people describe after a good group.
Universality: “Wait, you too?” A lot of suffering comes with a quiet belief that you’re the only one. The only one who still can’t get through the holidays after the divorce. The only guy at work who lies awake with his heart pounding. Hearing someone else describe your exact private thought, out loud, does something a therapist’s reassurance often can’t. Shame shrinks fast when it turns out to be shared.
Hope you can see. In ongoing groups, you’ll often sit next to someone who’s six months further along than you. Watching them laugh about something that used to flatten them is more convincing than any pep talk.
Being useful again. Yalom called this altruism. When you’re struggling, it’s easy to feel like a burden. In a group, you get to be the person whose comment helped someone else, and that changes how you see yourself.
Learning how you come across. This is where groups really differ from individual work. A group becomes a small version of your social world. If you always apologize before you speak, or go cold when someone gets emotional, it will show up in the room. With a skilled facilitator, other members can tell you kindly what they notice, and you can try something different right there, with people who have agreed to give you honest feedback.
Belonging. Researchers call it cohesion, and it’s one of the strongest predictors of how much people get out of a group. Feeling like you’re part of something, with people who show up for you every week, is healing in itself.
Who tends to get the most out of a group
Group work isn’t only for one diagnosis. It tends to fit people whose struggles are tied up with other people, or who feel cut off from them.
People who feel isolated. In 2023, then-U.S. Surgeon General Vivek Murthy issued an advisory calling loneliness and isolation a public health epidemic, noting that roughly half of American adults report feeling lonely. Plenty of people in that half have friends and family. What they lack is a place where they can be honest. A group provides that, on a schedule.
People dealing with anxiety. Anxiety, especially social anxiety, thrives on avoidance. A group is a safe, structured way to practice the exact thing anxiety tells you to skip, while learning coping tools at the same time.
People going through a loss or a big transition. Grief, divorce, a move, a career change, becoming a caregiver. These are lonely experiences even when people around you mean well. Being with others who are in the middle of something similar takes away the pressure to explain.
Men who don’t talk much about how they’re doing. Many men grew up with the message that problems get handled privately. A men’s group gives them a room where talking about stress, anger, or loneliness is the norm, not the exception.
Immigrants and people living between cultures. California is home to more immigrants than any other state. Adjusting to a new country, carrying family expectations from two places, feeling at home in neither: these are hard to explain to someone who hasn’t lived it. Groups built around that experience save people a lot of translating.
This is also why many practices now organize groups around shared experiences instead of running one general circle. Some practices that provide online group therapy in California, Heartfelt Flourish Psychotherapy among them, build their groups around specific needs such as anxiety, men’s issues, and the immigrant experience, so members start with something in common.
When a group might not be the right first step. If you’re in an acute crisis, actively thinking about suicide, or struggling with symptoms that make it hard to follow a conversation, individual care usually comes first. The same goes if you’re in the early, raw days after a trauma and not yet ready to hear other people’s stories. A good group leader will talk this through with you honestly during screening. If you are in crisis right now, call or text 988 to reach the Suicide & Crisis Lifeline any time, day or night.
Online groups in California: what changes on a screen
For a state this big, online groups solve real problems. If you live in Fresno or Redding, you may not have a specialized group within driving distance. If you live in Los Angeles or the Bay Area, you might, but getting there at 6 p.m. on a Tuesday is its own kind of therapy. Logging in from home takes the commute, the parking, and the babysitter math out of the equation.
A few things are worth knowing before you join an online group.
Your therapist needs a California license. Under California’s Board of Behavioral Sciences regulations, anyone providing psychotherapy by telehealth to a client who is physically located in California must hold a current California license or registration. That’s true even if the therapist happens to be traveling. The rule is based on where you are, not where they are.
You should get their license number. The same regulations require clinicians to give you their license or registration number and type when telehealth services begin. You can look it up yourself on the California Department of Consumer Affairs license search. It takes about a minute, and it’s worth doing for any therapist.
They’ll ask where you are each session. Don’t be surprised if the facilitator confirms your location at the start. California’s telehealth rules require clinicians to document it, partly so they know where to send help in an emergency.
Privacy is partly on you. Find a spot where people in your home can’t hear the group, and wear headphones so other members’ voices stay private too. Many groups ask members not to join from a car in motion, a coffee shop, or a shared office. That’s about protecting everyone in the room, not just you.
It may feel a little flat at first. Some people say the warmth takes a couple of sessions longer to build on video. That matches what researchers have found. Keeping your camera on, when you can, helps the group bond faster.
Your first session, honestly
Most people are nervous before their first group. That’s normal, and every facilitator expects it.
Before you ever join, a good group will usually have you do a screening conversation with the leader. It’s a chance for them to make sure the group fits what you need, and for you to ask questions. You’ll often sign or agree to group guidelines at that point.
The first meeting usually starts with introductions. You’ll be asked to share something small, often your first name and what brought you there, in as much or as little detail as you want. Then the facilitator walks through the group agreements. Common ones include:
- What’s said in group stays in group. Members don’t share names or stories outside.
- Show up on time and let the group know if you’ll miss a session.
- Speak from your own experience and avoid giving unsolicited advice.
- Members don’t socialize privately outside group, or if they do, they bring it back to the group.
- If you’re thinking about leaving the group, you talk about it in session first.
It’s worth understanding one limit of confidentiality. Your therapist is bound by law and professional ethics to protect what you share, with a few legal exceptions, such as immediate safety risks. Other members agree to keep things private, but they aren’t licensed professionals and aren’t bound in the same legal way. Most groups take this seriously, and in practice members tend to be very protective of each other. Still, it’s fair to share at your own pace.
After that, the session finds its rhythm. In a skills group, the leader may introduce a topic, like spotting anxious thoughts, and invite members to talk about how it shows up for them. In a process group, the conversation is looser and follows whatever is alive in the room that day.
You don’t have to talk much in the first few sessions. Listening counts. Many people say the turning point came when they finally said one true thing out loud and nobody flinched.
How to tell a well-run group from a weak one
Not every group is created equal. A few signs of a group that’s likely to be worth your time:
- There’s a screening process. If you can sign up and show up without anyone talking to you first, be cautious. Screening protects you and the other members.
- The purpose is clear. You should know what the group is for, who it’s for, and roughly how it runs before you join.
- The leader is licensed and trained in group work. In California, look for a license such as LMFT, LCSW, LPCC, or a psychologist license, or a registered associate working under supervision. Some group therapists also hold the Certified Group Psychotherapist (CGP) credential, which is linked to AGPA and requires specific group training.
- The group stays small. Somewhere around five to ten members gives everyone time to speak.
- Agreements are spelled out. Confidentiality, attendance, and what happens when conflict comes up should all be explained clearly.
- Conflict is handled, not avoided. Disagreements happen. A skilled leader helps the group work through them instead of shutting them down or letting one person take over.
- Costs are transparent. You should know what a session costs, whether your insurance applies, and what the cancellation policy is.
If something about a group doesn’t feel right after a few sessions, bring it up with the facilitator. That conversation is often useful in itself. And if the fit still isn’t there, it’s okay to look for another group.
Questions people ask before signing up
Is group therapy cheaper than individual therapy?
Usually, yes. Because the clinician’s time is shared, a group session typically costs less than an individual session of similar length. Exact pricing and insurance coverage vary, so ask directly.
Can I do group and individual therapy at the same time?
Many people do, and the two often work well together. Individual sessions give you room to go deep on personal history, while the group gives you a place to practice. If you already have a therapist, let them know you’re joining a group.
What if I know someone in the group?
Tell the facilitator as soon as you realize it. In an online group that draws from across California, it’s less likely, but it happens. The leader will help you decide whether it’s workable.
How long will I be in a group?
It depends on the format. Structured groups may run 8 to 16 weeks. Ongoing process groups often ask for a commitment of several months, since the benefits build over time.
What if I hate it after the first session?
Give it a few weeks if you can. The first session is often the most awkward one. If it still doesn’t feel right after three or four meetings, talk with the leader about whether a different group, or individual therapy, would serve you better.
The bottom line
Group therapy isn’t a lesser form of help, and it isn’t about performing your problems for an audience. At its best, it’s a small, carefully held space where you learn that you’re less alone than you thought, and where you get to practice being yourself with other people.
If you’re curious, start with a screening conversation with a licensed group leader. Ask what the group focuses on, how it runs, and whether they think it fits. You don’t have to decide anything in that call. You just have to be curious enough to ask.
