What is peer support, and what does the evidence say?

On this plate (6 sections)

Peer support is one of the oldest ideas in mental health advocacy and one of the newest job titles in health services. The core idea is simple: a person who has lived through a mental health condition offers support to someone going through something similar. This plate explains what peer support is, the forms it takes in the United States and England, how it differs from clinical treatment, what research reviews say about it, and whether it can be paid work. Anyone with concerns about their own health should speak with a clinician.

What peer support is

The US Substance Abuse and Mental Health Services Administration (SAMHSA) says that peer support workers are people who have been successful in the recovery process who help others experiencing similar situations. Through "shared understanding, respect, and mutual empowerment", SAMHSA says, they help people become and stay engaged in recovery. The agency adds that peer services can extend the reach of treatment beyond the clinical setting into everyday life.

Mind, the English charity, describes the same idea in the language of advocacy: peer advocates are people with lived experience of a mental health problem who can support you and offer advice based on their own experience. The wider setting is covered in the plate on what mental health advocacy is, and the comparison of kinds is in the five types of advocacy.

Forms peer support takes

Two broad forms appear in the sources. The first is informal or peer-run support, such as groups where people with similar experiences meet. Mind calls this group or collective advocacy and says it helps people strengthen their voice together. The second is a paid or formal role inside a service. SAMHSA lists activities such as advocating for people in recovery, sharing resources and building skills, building community, leading recovery groups, and mentoring and goal setting. It adds that roles may extend to providing training, supervising other peer workers, developing resources, administering programs and educating the public and policymakers.

In England, an NHS trust (NELFT) describes peer support workers as people with lived experience who provide "social, emotional and practical support" and share their experience to show that recovery is possible. The World Health Organization, on a page dated 11 September 2026, includes peer support in its list of community-based services, alongside community mental health centers and teams, psychosocial rehabilitation and supported living.

How it differs from clinical treatment

The same NHS trust page states plainly that its peer support workers "are NOT clinically trained and they are not therapists", and that peer support "does not replace the need for effective clinical advice, support, and information." SAMHSA likewise frames the role around shared understanding and shared experience of recovery. In practice, a peer may help someone prepare for an appointment or feel less alone, while diagnosis and treatment decisions stay with clinicians. The plate on preparing for an appointment shows how that support can fit around a visit.

What the evidence shows, and its limits

Evidence is mixed, and honest summaries say so. A 2021 systematic review and meta-analysis in BMC Psychiatry by Natasha Lyons, Chris Cooper and Brynmor Lloyd-Evans looked at group peer support. It included eight trials. The authors found that group peer support "may make small improvements to overall recovery" but not hope or empowerment individually, or clinical symptoms. They noted that six trials had high or unclear risk of bias and that interventions varied widely. Their conclusion was that there was "insufficient evidence available from trials of group peer support to recommend the routine implementation" of these interventions across mainstream services at that time.

A 2025 article by the Centre for Mental Health summarizes a wider review. The NIHR Policy Research Unit in Mental Health pulled together 35 systematic reviews of paid peer support and reported mixed results, with some signs that peer support may help with depression, particularly perinatal depression, and with self-belief and personal recovery. The authors say more work is needed to learn which models work best in which settings, and that the role can bring emotional challenges and is not right for everyone.

Neither source shows that peer support works for everyone or replaces other care. The 2021 review also describes the interventions it examined as varied. Readers should treat the findings as a cautious outline rather than a verdict.

Can you earn a living in peer support?

A legacy question on this topic is whether a person can make money as a mental health advocate. For peer support, the sources show that paid roles exist. The NHS trust page says additional lived experience peer support workers were employed there, and SAMHSA describes supervisory and program roles. The Centre for Mental Health article reports that an NHS audit in 2023 counted over 1,000 peer workers in NHS-commissioned mental health services in England, and describes it as one of the largest workforce changes in the sector in a decade.

The same article is candid about problems. It names low pay, limited career progression, no recognized certification for the role and unclear role definitions among the barriers, and quotes one expert saying that many peer workers are on voluntary or temporary contracts with little supervision. None of the opened pages gave a dated salary figure, so none is stated here. Conditions differ by country, employer and year, so anyone considering this path would need to check current job listings and local training requirements. Other advocacy work, such as the roles described in how to request an advocate, is often delivered by charities and may use paid staff or volunteers, as Mind notes.

The short version

Peer support is help from people with lived experience, delivered in peer-run groups or in paid roles inside services. It is not clinical treatment, and the research so far is mixed and limited, with small recovery benefits in some studies. Paid roles exist, though sources describe pay and career structure as unsettled.
