Veteran Loneliness After Service: The Numbers, the Causes and What Helps

Loneliness after service is common and measurable. A 2017 survey of 2,007 British veterans found that 41% had felt lonely or isolated since leaving, and a 2026 US study found that 22.4% of veterans report frequent loneliness. The research links loneliness to depression, PTSD and suicidal thoughts, and a 2022 review of 28 studies suggests that interventions built around social connection can ease it. This article sets out the numbers, the likely causes tied to leaving the forces, the limits of the evidence, and what helps.

Loneliness and social isolation are different things

The 2023 US Surgeon General's advisory "Our Epidemic of Loneliness and Isolation" defines loneliness as "a subjective distressing experience that results from perceived isolation or inadequate meaningful connections". It defines social isolation as "objectively having few social relationships, social roles, group memberships, and infrequent social interaction". A veteran can live among people and feel lonely, or live alone and feel fine. The advisory reports that loneliness and social isolation increase the risk of premature death by 26% and 29% respectively.

The numbers for veterans

Read these figures with their limits in mind. The US study is cross-sectional and relies on self-report, so it shows association and cannot show which came first. The UK survey covers veterans aged 18 to 64 and dates from 2017. The scoping review authors note that most research uses retrospective self-reports, which are vulnerable to memory bias.

Why leaving service raises the risk

Three strands of research point to circumstances that come with leaving the forces.

• Losing the unit. In the SSAFA survey, the most common reason for loneliness was losing touch with service friends (41%), followed by physical or mental health problems (33%) and difficulty relating to civilian life (23%).
• Losing the role. Williams and colleagues interviewed 20 retired servicemen, all Royal British Legion members. In their 2018 study participants described handing back identity cards, watches and equipment, feeling "marked" as neither military insiders nor fully accepted civilians, and losing the camaraderie of a "family". The Legion's coffee mornings and events gave them belonging and routine.
• Holding a strong military identity. Binks and Cambridge interviewed seven former British service personnel. Their 2016 study in Political Psychology reported that individuals with a more salient military identity had more difficult transition experiences. The sample is small, so the finding suggests a pattern and proves nothing.

Together these studies describe loneliness as something that follows from losing a unit, a role and a daily routine at once. The sources do not describe a fixed personality trait, and none of them set out to test that question directly.

What the 28-study review found

Gettings and colleagues reviewed 28 studies of interventions for veterans with PTSD and published their results in Frontiers in Psychology in July 2022. They identified six themes: rethinking the diagnosis of PTSD, holistic interventions, peer support, social reintegration, empowerment through purpose and community, and building trust. Their conclusion is that interventions with a direct focus on social connection may mitigate experiential loneliness and social isolation in veterans with PTSD, and that future work should consider bespoke interventions for tackling loneliness. Our companion article goes through the intervention types study by study.

The review has clear limits:

• Twenty-one of the 28 studies were US-based. Two were from the UK, two from Israel, two from Australia and one from Denmark.
• Many studies used small cohorts with limited statistical power.
• The authors chose not to apply a quality-assessment tool.
• Some studies relied on self-reported PTSD instead of clinical assessment, and few included a six-month follow-up.
• The paper gives two counts of studies that directly address loneliness or isolation: 11 for isolation and 2 for loneliness in the abstract, and 15 in the discussion.

What helps

The evidence supports structured contact with people who share your experience. Options with a public route in:

The network and charity comparison gives more detail on each group. The VA is clear that peer groups sit alongside evidence-based treatment. If loneliness comes with low mood, nightmares, heavy drinking or thoughts of suicide, contact a clinician as well as a peer group. In England, NHS Op COURAGE accepts self-referral from veterans who served for at least one full day.

How to help a veteran who seems isolated

The SSAFA survey gives practical pointers. Of the veterans surveyed, 53% said they would be unlikely to discuss loneliness with a family member or close friend, so a direct question about how someone is coping may meet a closed door at first. Another 27% said they would benefit from regularly meeting someone with a military background. Four steps follow from those figures:

1. Offer an activity. An invitation to a breakfast club, a branch event or a volunteer day is easier to accept than a conversation about feelings.
2. Go with them the first time. Walking into a room of strangers is the hardest part.
3. Use a signposting line. Veterans' Gateway (0808 802 1212) and the Royal British Legion helpline (0808 802 8080) both handle first contact for veterans and families.
4. Escalate when needed. Persistent low mood, heavy drinking or talk of suicide calls for a clinician or a crisis line.
