For a small minority of personnel, military service can have a negative impact on their mental health. Yet no studies have assessed how the mental health of UK veterans (who served during the recent operations in Afghanistan or Iraq) compares to non-veterans, to determine if they are at a disadvantage. We examine the prevalence of mental disorders and alcohol misuse in UK veterans compared to non-veterans.

Veteran data were taken from the third phase of the King's Centre for Military Health Research cohort study (n = 2917). These data were compared with data on non-veterans taken from two large general population surveys: 2014 Adult Psychiatric Morbidity Survey (n = 5871) and wave 6 of the UK Household Longitudinal Study (UKHLS, n = 22 760).

We found that, overall, UK veterans who served at the time of recent military operations were more likely to report a significantly higher prevalence of common mental disorders (CMD) (23% v. 16%), post-traumatic stress disorder (PTSD) (8% v. 5%) and alcohol misuse (11% v. 6%) than non-veterans. Stratifying by gender showed that the negative impact of being a veteran on mental health and alcohol misuse was restricted to male veterans. Being ill or disabled was associated with a higher prevalence of CMD and PTSD for both veterans and non-veterans.

Whilst the same sociodemographic groups within the veteran and non-veteran populations seemed to have an increased risk of mental health problems (e.g. those who were unemployed), male veterans, in particular, appear to be at a distinct disadvantage compared to those who have never served.

Veterans with post-traumatic stress disorder (PTSD) typically report a poorer treatment response than those who have not served in the Armed Forces. A possible explanation is that veterans often present with complex symptoms of PTSD. ICD-11 PTSD and complex PTSD (CPTSD) have not previously been explored in a military sample.

This study aimed to validate the only measure of ICD-11 PTSD and CPTSD, the International Trauma Questionnaire, and assess the rates of the disorder in a sample of treatment-seeking UK veterans.

A sample of help-seeking veterans (N = 177) was recruited from a national charity in the UK that provides clinical services to veterans. Participants completed measures of ICD-11 PTSD and CPTSD as well as childhood and adult traumatic life events. Confirmatory factor analysis was used to assess the latent structure of PTSD and CPTSD symptoms, and rates of the disorders were estimated.

The majority of the participants (70.7%) reported symptoms consistent with a diagnosis of either PTSD or CPTSD. Results indicated the presence of two separate disorders, with CPTSD being more frequently endorsed (56.7%) than PTSD (14.0%). CPTSD was more strongly associated with childhood trauma than PTSD.

The International Trauma Questionnaire can adequately distinguish between PTSD and CPTSD within clinical samples of veterans. There is a need to explore the effectiveness of existing and new treatments for CPTSD in military personnel.

Post-traumatic stress disorder (PTSD) is a potentially chronic and disabling disorder affecting a significant minority of people exposed to trauma. Various psychological treatments have been shown to be effective, but their relative effects are not well established.

We undertook a systematic review and network meta-analyses of psychological interventions for adults with PTSD. Outcomes included PTSD symptom change scores post-treatment and at 1–4-month follow-up, and remission post-treatment.

We included 90 trials, 6560 individuals and 22 interventions. Evidence was of moderate-to-low quality. Eye movement desensitisation and reprocessing (EMDR) [standardised mean difference (SMD) −2.07; 95% credible interval (CrI) −2.70 to −1.44], combined somatic/cognitive therapies (SMD −1.69; 95% CrI −2.66 to −0.73), trauma-focused cognitive behavioural therapy (TF-CBT) (SMD −1.46; 95% CrI −1.87 to −1.05) and self-help with support (SMD −1.46; 95% CrI −2.33 to −0.59) appeared to be most effective at reducing PTSD symptoms post-treatment v. waitlist, followed by non-TF-CBT, TF-CBT combined with a selective serotonin reuptake inhibitor (SSRI), SSRIs, self-help without support and counselling. EMDR and TF-CBT showed sustained effects at 1–4-month follow-up. EMDR, TF-CBT, self-help with support and counselling improved remission rates post-treatment. Results for other interventions were either inconclusive or based on limited evidence.

EMDR and TF-CBT appear to be most effective at reducing symptoms and improving remission rates in adults with PTSD. They are also effective at sustaining symptom improvements beyond treatment endpoint. Further research needs to explore the long-term comparative effectiveness of psychological therapies for adults with PTSD and also the impact of severity and complexity of PTSD on treatment outcomes.

The principles of the Armed Forces Covenant state that Armed Forces Veterans should be at no disadvantage resulting from their service compared with a general adult population. However, despite being at increased risk of experiencing common mental health difficulties, evidence indicates that 82% of Armed Forces Veterans receive no treatment, compared with 63% of the general adult population.

To gain a better appreciation of factors that inform the type of adaptations to cognitive behavioural therapy (CBT) interventions for depression and mainstream service promotion materials to enhance acceptability for Armed Forces Veterans.

This is a qualitative study employing a focus group of 12 participants to examine the main impacts of depression on Armed Forces Veterans alongside attitudes towards terminology and visual imagery. Thematic analysis was used to identify themes and sub-themes with rigour established through two researchers independently developing thematic maps to inform a final agreed thematic map.

A behavioural activation intervention supporting re-engagement with activities to overcome depression had good levels of acceptability when adapted to reflect an Armed Forces culture. Preferences regarding terminology commonly used within CBT adapted for Armed Forces Veterans were identified. Concerns were expressed with respect to using imagery that emphasized physical rather than mental health difficulties.

There is the need to consider the Armed Forces community as a specific institutional culture when developing CBT approaches with potential to enhance engagement, completion and recovery rates. Results have potential to inform the practice of CBT with Armed Forces Veterans and future research.

Little is known about the prevalence of mental health outcomes in UK personnel at the end of the British involvement in the Iraq and Afghanistan conflicts.

We examined the prevalence of mental disorders and alcohol misuse, whether this differed between serving and ex-serving regular personnel and by deployment status.

This is the third phase of a military cohort study (2014–2016; n = 8093). The sample was based on participants from previous phases (2004–2006 and 2007–2009) and a new randomly selected sample of those who had joined the UK armed forces since 2009.

The prevalence was 6.2% for probable post-traumatic stress disorder, 21.9% for common mental disorders and 10.0% for alcohol misuse. Deployment to Iraq or Afghanistan and a combat role during deployment were associated with significantly worse mental health outcomes and alcohol misuse in ex-serving regular personnel but not in currently serving regular personnel.

The findings highlight an increasing prevalence of post-traumatic stress disorder and a lowering prevalence of alcohol misuse compared with our previous findings and stresses the importance of continued surveillance during service and beyond.

Many people confront potentially morally injurious experiences (PMIEs) in the course of their work which can violate deeply held moral values or beliefs, putting them at risk for psychological difficulties (e.g. post-traumatic stress disorder (PTSD), depression, etc.).

We aimed to assess the effect of moral injury on mental health outcomes.

We conducted a systematic review and meta-analysis to assess the association between work-related PMIEs and mental health disorders. Studies were independently assessed for methodological quality and potential moderator variables, including participant age, gender and PMIE factors, were also examined.

Thirteen studies were included, representing 6373 participants. PMIEs accounted for 9.4% of the variance in PTSD, 5.2% of the variance in depression and 2.0% of the variance in suicidality. PMIEs were associated with more symptoms of anxiety and behavioural problems (e.g. hostility), although this relationship was not consistently significant. Moderator analyses indicated that methodological factors (e.g. PMIE measurement tool), demographic characteristics and PMIE variables (e.g. military v. non-military context) did not affect the association between a PMIE and mental health outcomes.

Most studies examined occupational PMIEs in military samples and additional studies investigating the effect of PMIEs on civilians are needed. Given the limited number of high-quality studies available, only tentative conclusions about the association between exposure to PMIEs and mental health disorders can be made.

None.

To identify factors that affected well-being among British embassy staff based in Japan after the 2011 earthquake, tsunami, and nuclear meltdown.

In-depth qualitative interviews were conducted with 36 members of staff 8 to 9 months after the earthquake.

Participants described their crisis work as stressful, exciting, and something of which they were proud. Aside from disaster-specific stressors, factors identified as stressful included unclear roles, handing over work to new personnel, being assigned to office-based work, feeling that work was not immediately beneficial to the public, not taking good-quality breaks, and difficulties with relatives. The radiation risk provoked mixed feelings, with most participants being reassured by contact with senior scientists.

Interventions to safeguard the well-being of personnel during crisis work must consider the impact of a broad range of stressors.(Disaster Med Public Health Preparedness. 2014;0:1-7)

Research of military personnel who deployed to the conflicts in Iraq or Afghanistan has suggested that there are differences in mental health outcomes between UK and US military personnel.

To compare the prevalence of post-traumatic stress disorder (PTSD), hazardous alcohol consumption, aggressive behaviour and multiple physical symptoms in US and UK military personnel deployed to Iraq.

Data were from one US (n = 1560) and one UK (n = 313) study of post-deployment military health of army personnel who had deployed to Iraq during 2007–2008. Analyses were stratified by high- and low-combat exposure.

Significant differences in combat exposure and sociodemographics were observed between US and UK personnel; controlling for these variables accounted for the difference in prevalence of PTSD, but not in the total symptom level scores. Levels of hazardous alcohol consumption (low-combat exposure: odds ratio (OR) = 0.13, 95% CI 0.07–0.21; high-combat exposure: OR = 0.23, 95% CI 0.14–0.39) and aggression (low-combat exposure: OR = 0.36, 95% CI 0.19–0.68) were significantly lower in US compared with UK personnel. There was no difference in multiple physical symptoms.

Differences in self-reported combat exposures explain most of the differences in reported prevalence of PTSD. Adjusting for self-reported combat exposures and sociodemographics did not explain differences in hazardous alcohol consumption or aggression.

Most accounts of deployment mental health in UK armed forces personnel rely on retrospective assessments.

We present data relating to the burden of mental ill health and the effect of support measures including operational, family, welfare and medical support obtained on two occasions some 18 months apart.

A total of 2794 personnel completed a survey while deployed to Afghanistan; 1363 in 2011 and 1431 in 2010. Their responses were compared and contrasted.

The prevalence of self-report mental health disorder was low and not significantly different between the surveys; the rates of probable post-traumatic stress disorder (PTSD) were 2.8% in 2010 and 1.8% in 2011; for common mental health disorders the rates were 17.0% and 16.0% respectively. Remembering receiving predeployment psychoeducation, perceptions of good leadership and good family support were all significantly associated with better mental health. Seeking support from non-medical sources and reporting sick for medical reasons were both significantly associated with poorer mental health.

Over a period of 18 months, deployment mental health symptoms in UK armed forces personnel were fewer than those obtained from a military population sample despite continuing deployment in a high-threat context and were associated with perceptions of support.

To examine the use of vitamin D supplements during infancy among the participants in an international infant feeding trial.

Longitudinal study.

Information about vitamin D supplementation was collected through a validated FFQ at the age of 2 weeks and monthly between the ages of 1 month and 6 months.

Infants (n 2159) with a biological family member affected by type 1 diabetes and with increased human leucocyte antigen-conferred susceptibility to type 1 diabetes from twelve European countries, the USA, Canada and Australia.

Daily use of vitamin D supplements was common during the first 6 months of life in Northern and Central Europe (>80 % of the infants), with somewhat lower rates observed in Southern Europe (>60 %). In Canada, vitamin D supplementation was more common among exclusively breast-fed than other infants (e.g. 71 % v. 44 % at 6 months of age). Less than 2 % of infants in the USA and Australia received any vitamin D supplementation. Higher gestational age, older maternal age and longer maternal education were study-wide associated with greater use of vitamin D supplements.

Most of the infants received vitamin D supplements during the first 6 months of life in the European countries, whereas in Canada only half and in the USA and Australia very few were given supplementation.

The 2011 earthquake and tsunami in Japan caused a meltdown at the Fukushima nuclear power plant.

To quantify emotional responses among British nationals in Japan and to assess whether perceptions about the incident or accessing information about it were associated with responses.

A total of 284 participants randomly selected from official records completed a survey that included instruments to measure emotional responses.

In total, 16% met the criteria for distress, 29.7% reported high anxiety relating to the incident and 30.4% reported high anger. Perceptions that strongly predicted these outcomes included feeling uncertain, being unable to rule out harmful exposure, and believing that exposure would have severe or hidden health effects or be difficult to detect. Using information sources was associated with higher emotional outcome, particularly for sources perceived to have low credibility.

Reducing uncertainty and improving the credibility of information is essential in reducing the psychological impact of radiological disasters.

Most studies of the mental health of UK armed forces focus on retrospective accounts of deployment and few sample personnel while they are deployed.

This study reports the results of a survey of deployed personnel, examining the perceived impact of events at home and military support for the family on current mental health during the deployment.

Surveys were conducted with 2042 British forces personnel serving in Iraq and Afghanistan. Prevalence of common mental disorders was assessed with the 12-item General Health Questionnaire (GHQ-12) and post-traumatic stress disorder (PTSD) was assessed with the PTSD Checklist – Civilian version (PCL-C).

The prevalence of common mental disorders was 17.8% and of probable PTSD was 2.8%. Perceived home difficulties significantly influenced the mental health of deployed personnel; the greater the perception of negative events in the home environment, the greater the reporting of adverse mental health effects. This finding was independent of combat exposure and was only partially mitigated by being well led and reporting subjectively good unit cohesion; however, the effect of the totality of home-front events was not improved by the latter. Poor perceived military support for the family had a detrimental impact on deployment mental health.

The armed forces offer many support services to the partners and families of deployed personnel and ensuring that the efforts being made on their behalf are well communicated might improve the mental health of deployed personnel.
