Group Therapy Vs Individual Therapy: How To Choose In 2026

Group therapy vs individual therapy comes down to what you’re treating and how private your story needs to stay. An open court case changes the math too.

In head-to-head research on depression and PTSD, individual therapy showed more improvement by the end of treatment. At follow-up, the differences in symptoms were no longer significant. For adults with social anxiety, the UK’s national clinical guideline favors individual CBT. Groups let you practice with real people and hear from peers who share your problem.

I’m Dr. Cathy Colet, a licensed clinical and forensic psychologist and the founder of FC PsychExperts in Jupiter, Florida. I started the practice in 2008, and Florida courts regularly call on me for evaluations and expert testimony. That court work adds a factor most comparisons leave out: what Florida law protects in each format.

What’s The Difference Between Group And Individual Therapy?

Group therapy vs individual therapy is a choice about format. In individual therapy, you meet one-on-one with a licensed therapist on a schedule set around you. In group therapy, a therapist leads a small group of clients through the same plan. Both can use the same methods, such as CBT. They differ in pace, privacy, and legal protection.

	Individual therapy	Group therapy
Who’s in the room	You and 1 licensed therapist	1 or 2 therapists and other clients
Session length	50 minutes at our practice	Varies by program; in a 2017 PTSD trial, groups ran 90 minutes and individual sessions ran 60
Pace	Set around your goals	Set by the group’s plan
Who must keep it private	Your therapist, under law and ethics rules	Your therapist; other members only under group rules
Florida privilege law (section 90.503)	Covers your talks with a psychotherapist, with exceptions	Doesn’t mention group members
Research edge	More improvement by the end of treatment in depression and PTSD research; favored for adult social anxiety	No significant difference in symptoms at follow-up in depression and PTSD research

Is Group Therapy As Effective As Individual Therapy?

For depression and PTSD, it comes close. In head-to-head research, one-on-one therapy showed more improvement by the end of treatment. The gap in symptoms had faded by follow-up. Social anxiety in adults is the exception, and there the evidence leans toward individual CBT.

Depression: a small early edge for individual therapy

Cuijpers and colleagues pooled 15 studies that compared individual and group therapy for adult depression head to head (European Journal of Psychiatry, 2008). One-on-one therapy came out ahead right after treatment, by a small margin (an effect size of 0.20). People in one-on-one therapy were also less likely to drop out.

At follow-up, the difference was no longer statistically significant. The authors said it isn’t clear the early edge is big enough to matter in treatment. They also flagged the small number of studies and their limited quality. Given those results, a CBT group is a reasonable option for mild to moderate depression. That holds only if you’re not having thoughts of suicide.

PTSD: a 268-person trial favored individual sessions

In a 2017 JAMA Psychiatry trial, 268 active-duty service members with PTSD got cognitive processing therapy (CPT) for 6 weeks. About half met in groups of 8 to 10 for 90-minute sessions. The rest met one-on-one for 60 minutes.

One-on-one CPT cut PTSD symptoms more by the end of treatment (an effect size of 0.6). At 6 months, the 2 formats showed no difference in severity or remission. Everyone in the study was on active military duty, so civilian results may differ.

Our individual therapy covers trauma and PTSD, and our trauma therapy in Jupiter includes EMDR.

Social anxiety in adults: the guideline favors individual CBT

About 7.1% of U.S. adults had social anxiety disorder in the past year, according to NIMH estimates from a national survey run from 2001 to 2003. Social anxiety often gets pitched as a group problem. The logic sounds right: practice being around people, with people. In adults, the evidence leans the other way.

The UK’s National Institute for Health and Care Excellence (NICE) addresses this in its social anxiety guideline. Its recommendation 1.3.3 for adults advises against offering group CBT in place of individual CBT as a routine choice. NICE found group CBT works better than most other options, but less well than individual CBT.

A NICE-funded network meta-analysis, published in Lancet Psychiatry in 2014, pooled 101 trials and 13,164 people. One-on-one CBT beat a waitlist by a wider margin than group CBT did, with effect sizes of 1.19 and 0.92. NICE’s recommendations match those results. The ranges overlap, so the edge isn’t proven. If social anxiety is your main problem, start one-on-one, and add a group once you’ve built some skills.

Is Group Therapy Confidential?

It’s partly confidential. Your group therapist has legal and ethical duties to protect what you say. The other members aren’t your therapists, so their silence rests on the group’s rules.

Under the APA Ethics Code, a psychologist who runs a group must explain each person’s role at the start (Standard 10.03). The same rule covers the limits of confidentiality. Ask about both in the first session, and ask what happens if a member breaks the rules.

Limits apply to individual therapy too. At our practice, you get the limits of Florida law in writing at intake. Your therapist also goes over exceptions, such as risk of serious harm, in your first session. Our couples, family, and co-parenting sessions put more than 1 client in the room. Each uses its own confidentiality agreement, set before the first session.

Choosing Therapy During A Florida Court Case

Talk to your attorney before you pick a format if you have an open custody, injury, or criminal case. Florida law protects what you tell a psychotherapist, but the protection has limits. The privilege statute also doesn’t mention the other people in a group. This section is general information, not legal advice.

Whether to start therapy during a court case at all is its own decision, with its own trade-offs. Our practice does evaluations and expert testimony in Florida’s 1st, 15th, 17th, 19th, and 20th Judicial Circuits. Of the 3 exceptions below, 2 line up with evaluations we do.

The 3 exceptions in Florida’s privilege law

Florida’s privilege statute, section 90.503, gives you the right to keep confidential talks with a psychotherapist private in legal cases. It lists 3 exceptions.

Exception in section 90.503	What it means for you
Hospitalization hearings	If your psychotherapist believes you need hospital care and a court is asked to order it, related talks can come in.
Court-ordered exams	What you say in an exam a judge orders isn’t privileged.
Your condition is part of your claim or defense	If you rely on your mental or emotional state in a claim or defense, related talks can come in. An emotional-harm lawsuit may qualify, depending on how the claim is pled.

Other Florida laws reach past these 3. Under section 90.507, you can lose the privilege by agreeing to share a significant part of what you said. Speaking when you don’t have a reasonable expectation of privacy can also waive it. When a case involves known or suspected child abuse, abandonment, or neglect, section 39.204 removes the privilege for talks involving the person accused.

None of these rules mention group therapy. A court-ordered exam is also a different thing from therapy. What you tell the evaluator can end up in a report for the court. So a forensic psychological evaluation isn’t a substitute for treatment.

I work with both plaintiffs and defense attorneys in injury cases. Our personal and emotional injury evaluations fall under the third exception.

Who’s in the room changes the risk

The statute lets 3 kinds of people hear a confidential conversation without breaking it. Those are people there to further your interest and people needed to pass the message along. The third group is anyone taking part in your diagnosis and treatment under the psychotherapist’s direction.

Fellow group members aren’t named. The waiver rule adds a second question: whether you had a reasonable expectation of privacy when you spoke in front of them. Both are legal questions, so ask your attorney before you share case details in a group. Group members also aren’t treating you, and their promise to keep your story private comes from the group’s ground rules.

Before a Florida custody evaluation, keep case details for one-on-one sessions until your attorney weighs in.

When a judge orders treatment

Follow the court order if it names a program. Your format preference doesn’t override it. Florida’s batterers’ intervention programs, for example, must run at least 29 weeks and include 24 weekly sessions under section 741.325. When an order says therapy without naming a format, ask your attorney whether group sessions count before you enroll.

Our court-ordered therapy comes with dated attendance records, progress summaries, and a completion letter. They go where your order and your signed release say. The court gets what the order specifies, usually attendance and a progress summary. Before you begin, your clinician tells you in writing what gets reported. Some orders require in-person sessions, so bring yours to the first call. I oversee court-referred cases and their paperwork.

When Is Group Therapy The Better Fit?

A group fits when the problem plays out in how you deal with people, and you’re ready to work on it in front of others. The exception is social anxiety disorder in adults, where the evidence favors starting one-on-one.

It also makes sense when you want peers who share your problem. Some people join a group after finishing individual work, to keep their skills in use. Before you sign up, ask whether the leader screens members first. Also ask whether the group is closed, meaning the same members stay together until it ends, or open to new people at any time.

Our therapy services cover 5 formats: individual, family, couples, court-ordered, and co-parenting. If a group fits you better, ask your primary care doctor or current therapist for a referral.

When Individual Therapy Makes More Sense

Start one-on-one if the details are private, if trauma or adult social anxiety is the main problem, or if you have an open court case. A crisis comes before either format. Call 911 if you’re in immediate danger. Anyone thinking about suicide can call or text 988, or chat at 988lifeline.org, to reach the Suicide & Crisis Lifeline.

Our individual therapy sessions usually run 50 minutes, weekly or every other week. First sessions are usually available within the same week. You can come to our Jupiter or Fort Lauderdale office, or meet by secure video anywhere in Florida. Sessions use methods such as CBT, EMDR, and trauma-focused therapy. Jessica T. Aloise, LCSW, has practiced for more than 20 years and leads individual therapy. I direct clinical care.

Can You Do Both At Once?

Yes, and pairing weekly individual sessions with a group is common. It gives you a private place to work through what comes up in group.

Tell each therapist about the other, and sign releases so they can compare notes. When the problem lives in your household and not in you alone, family therapy is a third format to consider.

FAQs

Group therapy vs individual therapy: which works better for depression?

Individual therapy has a small early edge. A 2008 meta-analysis of 15 head-to-head studies found individual therapy slightly ahead right after treatment, with fewer dropouts. By follow-up, the 2 formats showed no statistically significant difference.

Group therapy vs individual therapy: which is better for PTSD?

A 2017 trial of 268 active-duty service members found individual cognitive processing therapy cut PTSD symptoms more by the end of treatment. At 6 months, the 2 formats showed no difference in severity or remission. Results in civilians may differ.

Is what I say in group therapy confidential?

Your group therapist is bound by law and professional ethics. The APA Ethics Code also requires psychologists to explain the limits of confidentiality when a group starts. Other members are bound only by the group’s rules. Section 90.503, Florida’s privilege statute, doesn’t mention group members, so ask your attorney before sharing details tied to an open court case.

Can my therapy records be used in a Florida court case?

Florida’s privilege statute, section 90.503, lets you keep confidential talks with a psychotherapist out of court by default. It lists 3 exceptions: hospitalization hearings, court-ordered exams, and claims or defenses that rely on your mental or emotional condition. Waiver rules and child abuse cases can also open records, so ask your attorney how these rules apply to your case.

Who should not do group therapy?

Groups are a poor first step for people in crisis and for people who need to discuss private details tied to a court case. The evidence also favors starting one-on-one for adults with social anxiety disorder. If you’re thinking about suicide, call or text 988 first. A licensed therapist can help you decide whether to start one-on-one and join a group later.

Can I do group and individual therapy at the same time?

Yes, and it’s a common pairing. Tell each therapist about the other and sign releases so they can coordinate. At FC PsychExperts, individual sessions usually run 50 minutes, weekly or every other week, so a weekly group can fit around them.
