Online peer support: forums, groups & warmlines
Sometimes the people who help most are the ones who’ve been there too, even if they’re on the other side of a screen.
By the numbers
What surveys and studies show about support online.
Research on online peer support is promising but still young. These numbers show how people use it and what studies have found so far.
How people use it
What research shows
What is online peer support?
Support from people with lived experience, through a screen or phone.
Peer support means getting and giving support with people who share a similar experience. Online, it happens in forums, video groups, apps, chat lines and social media.
Researchers have described people living with mental health conditions using social media to share their experiences and learn from each other. They see real potential in these connections.

Mental Health America notes online communities can be especially helpful if there are no groups in your area, and can add to in-person support.
Reading without posting is fine. Many people “lurk” for a while before joining in.

Peer support is a two-way street. Many people find that sharing what helped them gives their own experience new meaning.
What research shows so far
Promising, but still early.
A 2020 review of 30 studies found digital peer support for people with serious mental health conditions was workable and acceptable, with strong potential. The authors said bigger, better trials are still needed.
For young people, a 2015 review found only six studies, with mixed results. Almost all used groups with moderators.
Researchers have also flagged possible downsides: misleading information, hostile comments and feeling more unsure about your health. They judged the benefits seemed to outweigh these risks, but called for more study.
Signs of a healthy online community
What good spaces tend to have in common.
Green flags
- Active moderators who step in when things get unkind or unsafe
- Clear rules, such as no diagnosing, no selling and no graphic content
- Crisis information that is easy to find
- People share experiences rather than telling others what to do
- Respect for privacy, including usernames and no pressure to share
- Run or supported by a trusted organization
Red flags
- Advice to stop seeing your clinical provider or ignore their guidance
- Content that makes self-harm or disordered eating look normal or appealing
- Members who push you to move to private chats quickly
- Pressure to buy products, programs or “cures”
- Us-versus-them talk about families, professionals or “outsiders”
Warmlines: someone to talk to, before it’s a crisis
Peer-run lines for when you need a listening ear.
A warmline is a peer-run phone line, and sometimes chat or text, that offers emotional support. The people who answer have their own lived experience of mental health challenges.
Warmlines are not crisis hotlines, but SAMHSA says they should be able to tell when someone needs a crisis line or more help, and connect them.
Good to know
- Check whether a line takes calls from outside its area before calling
- Hours vary, and some lines are not open every day
- Many serve only one state or county
- Some offer text or chat, and some offer Spanish
NAMI keeps a national warmline directory listed by state on its HelpLine website. The NAMI HelpLine itself can also point you to local support.
Risks to watch for
Most spaces are kind, but not all.

Be wary of anyone who asks for money, photos, personal details or secrecy, or moves fast to private chat.
Sharing safely
Protecting your privacy while you open up.
Before you post
- Check how the site uses and shares your information
- Leave out details that could identify you, like your school, workplace or town
- Remember posts can be screenshotted and shared, even in “private” groups
- Use a username that isn’t your real name if you prefer
It’s okay to share a little at first and more over time as you build trust. You decide what is yours to tell.
Being a good peer online

Set limits on time and topics, and step away when you need to. You can care about people without being available all the time.
Balancing online and offline support
Online support as one part of a bigger circle.
Mental Health America reminds people that online support is not a replacement for talking with a mental health professional. It works best alongside other support.
Signs a group isn’t helping right now
- It is taking time from sleep, friends or things you enjoy
- You feel worse, more hopeless or more anxious after visiting
- You feel pressure to keep up with every post
- You hide how much time you spend there
Taking a break, muting a group or leaving is always okay. You can come back later or find a better fit.
When and where to get help
Peer support is great, and sometimes you need more.
Reach out to a clinical provider or therapist if…
- Daily life is getting harder to manage
- Online support isn’t easing how you feel
- You have been struggling for more than a couple of weeks
- You notice thoughts of harming yourself
