Total VeteranSocial Support and PTSD Treatment for Veterans: What the Evidence Shows
Guidelines recommend trauma-focused therapy first. Research also links stronger social support with lower PTSD severity. Here is how the evidence fits together, and its limits.
- NICE and VA/DoD guidance recommend individual trauma-focused therapy first, with medication in a secondary role.
- A meta-analysis of 37 studies found lower social support goes with more severe PTSD symptoms (r = -0.33).
- A 28-study review suggests connection-based programmes may reduce loneliness. Only 2 studies were UK-based.
- The VA states peer groups are not PTSD treatment and have not been shown to reduce symptoms.
The best evidence supports trauma-focused therapy as first-line treatment for PTSD, with social support as a companion to treatment. Official guidelines in the UK and US recommend trauma-focused psychological therapy first. Separate research links stronger social support with lower PTSD severity, and reviews suggest connection-based programmes may reduce loneliness in veterans. No source reviewed here shows that social support replaces treatment, and the VA states that peer groups are not PTSD treatment.
This article summarises published research and guidelines for general information. It gives no individual medical advice. A clinician can explain which options fit a particular person.
What each type of evidence says
| Evidence | What it shows | What it cannot show |
|---|---|---|
| UK and US guidelines: NICE NG116 (2018); VA/DoD Version 4.0 (2023) | Individual trauma-focused therapy comes first: trauma-focused CBT in NICE guidance, and cognitive processing therapy, prolonged exposure or EMDR in the VA/DoD guideline. Medication has a secondary role | Neither guideline names peer support as a substitute for therapy |
| Meta-analysis: Blais et al. (2021): 37 studies, 18,766 US service members and veterans | Lower social support goes with more severe PTSD symptoms (r = -0.33). Non-military support showed a stronger link than military support | Cross-sectional studies cannot show that support causes lower symptoms |
| Systematic review: Gettings et al. (2022): 28 studies | Interventions built around social connection may reduce loneliness and isolation in veterans with PTSD. Themes included peer support, social reintegration, purpose and trust | Small samples, little follow-up, 21 of 28 studies from the US and 2 from the UK, no formal quality rating |
| UK cohort: KCMHR Phase 4 (2022 to 2023) | Ex-serving personnel with poor social support had higher PTSD (18.2% against 4.9%) and CPTSD (11.4% against 2.9%) rates | Measured at one point in time, so the direction of the link is unclear |
| Trial-based model: DeGarmo and Gewirtz (2018): 336 post-deployed military parents | Parenting support buffered the effect of military trauma exposure on PTSD symptoms over two years. A parent training programme reduced symptoms in mothers (d = 0.41) and showed no such effect in fathers | A single programme with a parent-specific sample |
Where social support fits beside treatment
The VA/DoD guideline makes a strong recommendation for individual, manualised trauma-focused therapy over medication, and a strong recommendation for paroxetine, sertraline or venlafaxine when medication is used. It also notes that a co-occurring substance use disorder should not on its own rule out trauma-focused therapy. The NICE guideline (2018) opens by recognising that people with PTSD, including complex PTSD, may show interpersonal difficulties and negative self-perception alongside the core symptoms. The NICE adult pathway advises extra time to build trust with people with complex needs.
The social side shows up in three places in the evidence.
- Symptoms. ICD-11 includes difficulty sustaining relationships in its definition of complex PTSD. Our article on PTSD and complex PTSD sets out the criteria.
- Risk. In a Danish study of 599 treatment-seeking veterans, being single was a risk factor for CPTSD compared with no trauma disorder.
- Protection. The VA Center for PTSD course on social support states that social support appears to buffer the effects of loneliness and isolation, which are linked to other mental health problems including suicidal thoughts.
A 2025 review of reviews in the British Medical Bulletin by Billings and Nicholls adds a caution. Dropout from trauma therapy remains high, and evidence on adapting treatment for CPTSD is limited. Connection with family, friends and peers may help people start and stay in care, though the sources reviewed here do not test that directly.
Structure and people around you
Cohorts combine one-to-one coaching, a peer Bravo and a written plan for life after service. Coaching works alongside any clinical care you receive.
What the connection-based studies looked at
The Gettings review searched six databases and included 28 studies of veterans with PTSD. Eleven studies addressed social isolation directly and two addressed loneliness directly. The formats varied widely. The authors grouped findings into six themes: rethinking the PTSD diagnosis, holistic interventions, peer support, social reintegration, empowerment through purpose and community, and building trust.
The authors conclude that a direct focus on social reintegration, psychosocial functioning, trust, peer support, group cohesion and purpose-building may reduce loneliness and isolation in veterans with PTSD. They also list limits: English-language papers only, small samples, self-reported PTSD in some studies, few studies with a six-month follow-up and under-representation of women and ethnic minority veterans.
On peer groups, the VA Center for PTSD gives a plain statement. Groups help members feel less alone, learn coping tips and practise asking for help. They "have not been shown to reduce PTSD symptoms" and work best alongside evidence-based treatment.
What a combined approach looks like in practice
The sources describe two parallel tracks. Neither replaces the other.
| Track | UK options | US options |
|---|---|---|
| Clinical treatment | Op COURAGE, the NHS Veterans Mental Health and Wellbeing Service for England. NHS talking therapies accept self-referral from age 18 in most areas. GP referral for trauma-focused CBT or EMDR | VA facilities for trauma-focused therapy: cognitive processing therapy, prolonged exposure or EMDR. Secure video delivery is strongly recommended where validated or where options are limited |
| Connection and peer support | Combat Stress helpline for veterans, families and carers, 0800 138 1619, open 24 hours. Togetherall, an anonymous online community listed by the NHS | VA Peer Support Services and Peer Specialists, who are veterans with experience of mental health recovery. Vet Center support groups. 1-877-WAR-VETS (1-877-927-8387) to talk with a combat veteran |
| Family involvement | Op COURAGE accepts contact through a family member or friend, as well as self-referral | VA National Center for PTSD family guidance: learn about PTSD, consider family therapy, use crisis lines, PTSD Family Coach app |
Our article on Op COURAGE covers the England service in more detail, and the Bravo model describes one peer-support design.
Getting into care is a separate hurdle. In a 2004 study in the New England Journal of Medicine, only 23% to 40% of US soldiers and Marines who screened positive for a mental disorder after Iraq or Afghanistan sought care, and they were about twice as likely as others to report concerns about stigma.
Reading the evidence with care
Three points apply to everything above.
- Most of the social support evidence is correlational. People with fewer supports may have more severe symptoms, and people with more severe symptoms may lose supports.
- US samples dominate. The Gettings review found only 2 UK studies among its 28.
- Group averages say little about one person. A clinician, or a service such as Op COURAGE, can discuss what fits an individual.
UK: call Samaritans free on 116 123, any time. Combat Stress runs a free 24-hour helpline for veterans and families on 0800 138 1619. Op COURAGE, the NHS veterans mental health and wellbeing service for England, takes self-referrals through regional teams listed on the NHS veterans mental health page. In an emergency call 999, or call 111 and choose the mental health option.
US: the Veterans Crisis Line is open to veterans and the people supporting them. Dial 988 then press 1, text 838255, or use the online chat.
What to do this week
- Ask a GP or Op COURAGE team about trauma-focused CBT or EMDR before relying on peer groups alone.
- US: ask your VA facility about trauma-focused therapy and Peer Support Services in the same call.
- Name one family member or friend who can check in with you each week.
- Share the VA family guidance page with a partner or relative.
- Write down the questions you want to ask a clinician: therapy type, session numbers, waiting time.
